2017 Ford Taurus Key Replacement
Short answer: The 2017 Ford Taurus belongs to the Taurus Sixth generation refresh and uses a remote head key, a smart proximity key with push-button start and a transponder (chip) key. Its immobilizer chip: Texas 4D63 80-bit (remote-head key). We can usually add spare keys on site; some situations, such as all keys lost on certain trims, need extra steps or a dealer-supplied part. Julian's Locksmith cuts and programs Taurus keys on site; call (951) 903-3193 with your VIN for a quote.

Bought a used 2017 Ford Taurus and got one key at signing? That's common, and it's worth fixing early. A single key leaves you one lost pocket away from an all-keys-lost job, and you have no idea how many other keys the previous owners had programmed to the car. Julian's Locksmith can meet you in Southern California, verify the registration in your name, cut and program a second key, and, where the system allows, clear old keys from the immobilizer so only the ones in your hand will start the engine. It's a simple step that protects both the car and your budget, and we walk you through exactly what was done before we pack up.

The 2013 refresh carried over the 80-bit remote-head key for turn-key cars, while Intelligent Access cars moved to a newer smart fob, FCC ID M3N5WY8609, which was also sold with a remote-start button. Intelligent Access was most common on Limited and SHO models, and many SE and SEL cars kept the turned key. Production ended in early 2019, so the 2019 model year is the last Taurus sold in the US.
What's specific to the 2017 Taurus
The 2017 Ford Taurus is the fifth of 7 model years in the Taurus Sixth generation refresh (2013–2019), so it shares its key system with the rest of that run, which makes replacement parts easy to source. At roughly 9 years old, a 2017 Ford Taurus has usually seen real wear. Ignition and door cylinders on high-mileage cars wear along with the key, so we cut new keys to factory code rather than copying a worn key. Fob cases crack, buttons wear through and solder joints loosen at this age, so a new shell or a replacement remote often beats repairing the old one. Many have changed hands more than once, so erasing keys you can't account for is worth doing during the visit.
Smart-key cars like the 2017 Taurus can be targeted with relay attacks that extend the fob's signal from inside your home, so keep fobs away from exterior walls or in a signal-blocking pouch, and have any missing fob erased from the car.
Key options for the 2017 Ford Taurus
- Remote head key. Remote-head keys look similar across many vehicles, but the electronics inside are not interchangeable. Getting the right one for a Ford Taurus means matching the FCC ID and part number printed on the back or inside the case, the operating frequency, which is commonly 315 MHz on US-market cars, the transponder type, and the button layout. A trim with remote start or a power liftgate may use a four- or five-button version where a base trim uses three. We check those details against your VIN and your existing key, if you have one, before cutting the blade. A wrong match can look perfect and still refuse to program.
- Smart proximity key (push-to-start). A smart or proximity key lets a 2017 Ford Taurus open when you touch the door handle and start with a push of a button while the fob stays in your pocket or bag. Antennas in the doors and cabin send out a low-frequency wake-up signal; the fob answers on a higher radio frequency with an encrypted reply, and the car only allows a start once it confirms the fob is inside. When the fob battery is weak, that conversation fails, which is why most designs include a backup: hold the fob against the start button or set it in a designated pocket. The owner's manual shows where, and it's worth checking before you need it.
- Transponder (chip) key. A transponder key carries a small chip in its head, usually a glass capsule or a carbon wafer, with no battery of its own. When you turn the key in a 2017 Ford Taurus that uses one, an antenna ring around the ignition energizes the chip and asks for its code. If the answer matches what the immobilizer has stored, the engine is allowed to run. If it doesn't, you get the classic symptoms: the engine cranks but won't fire, or it fires and dies after a second, and the security light on the dash flashes or stays lit. That's why a perfectly cut copy without a programmed chip will open the doors but won't start the car.
How the Ford immobilizer works on the Taurus
- The M3N5WY8609 smart fob is shared with the 2013-2019 Flex and the 2011-2015 Explorer and Edge.
- The smart fob's emergency blade, Ford 164-R8041, carries no chip; it only opens the door.
- Catalogs list a five-button remote-head key with remote start, Ford 164-R8000, for 2012-2019 Tauruses.
Programming a 2017 Taurus key
Programming runs through the OBD-II port for both key styles. Owners with two working smart fobs can add a third on board, but a lost-key situation needs our programmer and the timed security access. We cut the emergency blade or the remote-head key on site. All-keys-lost is a single-visit job on most 2013-2015 cars, while later push-button cars can need an emulator or bypass cable first; either way we end with two working keys and the missing ones erased.
Nearly all Ford key programming runs through the OBD-II port. On turn-key Fords from roughly 2000 to 2014, our programmer requests PATS security access, often a timed wait of about ten minutes, and then adds a key or erases and rebuilds the key list. If you already have two working keys, many of these vehicles also accept Ford's owner procedure, where each good key is switched on in turn, followed by the newly cut key. A fixed-code 4C key can simply be cloned. Most separate remotes from that era pair when the ignition is cycled eight times in quick succession, while integrated remote-head keys usually learn their buttons along with the chip. Hitag Pro flip keys and every push-button fob are registered with a programmer. On many 2015-and-later models an active alarm means an emulator or bypass cable for all-keys-lost work, and some 2020-and-later models add an online authorization step. We check your ID and registration or title before we start.
Spare keys are routine; all-keys-lost on 2016-and-later push-button Tauruses can need an emulator or bypass cable, which we confirm by VIN.
Lost every key to your Taurus?
- Gather your documents and the VIN. Call with the year, make, model and VIN if you can read it through the windshield, plus where the car is parked. Those details let us confirm whether your Ford Taurus can be done on-site and bring the right key, so the first trip is the only trip.
- Get into the vehicle without damage. If the car is locked, we open it with non-destructive tools such as an inflatable wedge and a long-reach rod, or by picking the door lock. Some vehicles need a careful approach to avoid triggering the alarm, which can interfere with programming later.
- Originate a new key from the car. With no key to copy, the cuts come from the vehicle itself. We retrieve the key code through manufacturer channels where possible, or decode a door lock with a pick-decoder tool. Then we cut the blade on our code machine and confirm it turns the lock smoothly.
- Program the key to the immobilizer. Next, the new key is introduced to the car's security system. Many vehicles allow this through the OBD-II port with a PIN or security procedure. Some all-keys-lost cases require reading a module on the bench, and a few platforms only allow dealer programming, which we'll tell you up front.
- Erase missing keys and add a spare. Once the car starts, we remove the lost keys from memory wherever the system allows, so they can't start the engine if someone finds them. Making a second key during the same visit costs much less than a repeat all-keys-lost call down the road.
Why a spare key pays for itself
- A spare turns a future all-keys-lost emergency into a simple add-a-key job. With one working key in hand, programming is quicker, and the chip or fob can often be paired without decoding locks or reading modules, which keeps the cost of a lost key far lower.
- Some vehicles make it hard to add a key once you're down to one. Certain immobilizer systems let an owner program an extra key on-board only when two working keys are present, so a second key preserves the easy options for later and avoids a full reset.
- A spare stored safely at home rescues you from a locked car with the fob sitting on the seat, a key dropped somewhere along a hiking trail, or a fob that stops responding on a busy morning. Keep it indoors, never in a magnetic box under the bumper.
Dealer or mobile locksmith?
Dealers have one clear advantage: direct access to the manufacturer's own systems. Some newer vehicles tie key programming to online authorization that only a dealer can use, and certain all-keys-lost situations on specific platforms still require it. A good locksmith knows where those lines are. Where we can do the job, we use professional programming equipment that talks to the same immobilizer and keyless systems through the OBD-II port, and in many cases the result is identical: a properly registered key that starts the car. Where we can't, we can often still help by opening the vehicle, cutting a mechanical blade from code, or helping you gather what the dealer will ask for so that visit goes smoothly. For your Ford Taurus, ask us directly and you'll get a plain answer.
Taurus key battery
A fob battery rarely dies all at once. The warning signs build: you have to get closer to the car before the doors respond, the dash shows a key battery or key-not-detected message, or the push-button start only works with the fob held near the button. Inland heat speeds that decline, especially for fobs left in a hot cabin or on the dashboard. Keep a spare CR2032 at home in a cool drawer, sealed in its original package, and buy from a busy store where stock turns over quickly. A cell that sat on a shelf for years may arrive already partly spent.
How the job works
- Identify the exact key your Taurus uses. Every job starts with the VIN, the trim and a look at any key you still have. From those we confirm the keyway, the transponder or smart-key chip, the remote frequency, the FCC ID and the button layout. Two Ford Taurus keys that look identical can carry different electronics, so this step keeps the wrong part from ever reaching the car.
- Verify ownership before any work. Before cutting or programming, we compare your government photo ID with the vehicle registration or title and check that the VIN on the paperwork matches the VIN on the dash. If the registration is locked inside, we open the car first, confirm the documents, and only then make the key.
- Get the key code or decode the lock. A key is cut from a code, not a guess. When the factory code can be retrieved through manufacturer channels after ownership is verified, we use it. When it can't, we decode a door lock with a pick-decoder tool that reads the wafer positions without damaging anything, then work out any missing cuts.
- Cut the blade on-site. Cutting happens right beside your car. For a smart key, that means the emergency blade hidden inside the fob; for a transponder or remote-head key, it's the main blade you'll use every day. We deburr the cuts and check the fit in each lock so nothing binds or sticks later on.
- Program the chip, remote or smart key. With the blade done, we connect to the OBD-II port and register the new key with the immobilizer. Depending on the Ford system, this may involve a security PIN, a timed waiting period, or on-board button sequences for the remote. On some vehicles we clone a working key's chip instead, when that's the more reliable path.
- Test everything and clear out old keys. The last step is a short walkthrough. We show you how many keys the car now recognizes, point out the dead-fob start method for your vehicle, and hand you an itemized receipt. If a spare makes sense, it's simplest to add it during this same visit while the equipment is already connected.
What affects the price of a Taurus key
- The type of key. Price follows complexity. The more the key does, the more it costs to replace: brass blade, then chip, then remote buttons, then full keyless entry and push-button start. If your Taurus came with different key styles by trim, the one your car actually uses is the one that sets the quote.
- Factory or aftermarket parts. Factory keys and fobs carry the manufacturer's part number and usually the highest parts cost. Quality aftermarket keys use compatible electronics at a lower price and work well on many vehicles. We tell you which options we trust for your car, and where an aftermarket version has known range or fit issues, we steer you to OEM.
- Programming complexity and security access. Some immobilizers accept a new key with a few on-board steps. Others need a PIN code, a timed security wait, manufacturer online access, or removing a module to read its data. Every extra layer of security on the Ford system adds equipment time and labor to the job.
- Travel, timing and extra repairs. Because we come to you, the distance from our San Bernardino base and the time of the call play a part. So does anything we find along the way, such as a worn ignition cylinder or a seized door lock. You hear about each item and get a quote before we start work.
Call (951) 903-3193 with your VIN and the keys you still have, and we'll quote the job before any work starts.
Tips from a mobile locksmith
- On any vehicle with a turn-key ignition, keep the key ring light. A heavy cluster of keys, tools and charms swings with every bump and slowly wears the ignition wafers and the key itself. When the key starts to stick or needs a wiggle to turn, deal with it early, before it stops turning entirely.
- Every so often, use the mechanical blade in the driver's door lock. Cylinders that go years without a key can seize from dust and dried grease, and you won't find out until the day the fob dies and the blade is your only way in. A small shot of dry lubricant keeps the lock ready.
- Make the spare before you need it. Adding a key while one still works is quicker and less expensive than starting from nothing, and it keeps the simpler programming options available. Good moments are right after buying the car, or as soon as one of your two keys goes missing.
- Southern California heat is hard on keys. Fob batteries drain faster, plastic housings turn brittle, and rubber button pads crack when a key spends summer afternoons on a dashboard or in a sunny cup holder. Carry the fob with you or keep it shaded, and replace batteries before summer rather than after they fail.
- Photograph the back of your fob and any key tag that came with the car. The FCC ID, part number and key code printed there make ordering a replacement faster and more accurate. Store the photos somewhere you can reach from any device, not only on the phone that might go missing along with the keys.
Proof of ownership
Making car keys is regulated work in California. Locksmiths are licensed and overseen by the Bureau of Security and Investigative Services under the Locksmith Act, Business and Professions Code section 6980 and following, and Julian's Locksmith holds company license LCO7891. Verification protects you more than anyone: a locksmith who will make a key for whoever asks will also make one for someone who wants your car. We record your name, the vehicle and its VIN on a work order, and we politely decline jobs where ownership can't be established. You can look up our license at search.dca.ca.gov.

Frequently asked questions
Can a locksmith make a key for a 2017 Ford Taurus?
We can usually add spare keys on site; some situations, such as all keys lost on certain trims, need extra steps or a dealer-supplied part. Spare keys are routine; all-keys-lost on 2016-and-later push-button Tauruses can need an emulator or bypass cable, which we confirm by VIN. The 2017 Taurus uses a remote head key, a smart proximity key with push-button start and a transponder (chip) key.
Why does my Taurus crank but not start with a newly cut key?
That pattern points to the immobilizer, not the engine. The blade is cut correctly, so the ignition turns, but the car doesn't recognize the chip and blocks fuel or spark. A flashing security light usually confirms it. The key either wasn't programmed, carries the wrong chip type, or is an unprogrammed copy from a hardware store. Programming a correct key to your 2017 Ford Taurus resolves it.
Can you fix a broken Ford key instead of replacing it?
Often, yes. If the shell is cracked, the buttons are worn or the blade snapped, but the circuit board and chip are healthy, we can transfer the electronics into a new housing and cut a fresh blade to your key code. Your existing programming stays intact. If the board has been damaged by water or impact, a repair won't last, and we'll recommend a new programmed key instead.
Can you make a Taurus key from the VIN alone?
The VIN is a starting point, not a finished key. For many vehicles, the factory key code can be obtained from the VIN through manufacturer channels once ownership is verified, which lets us cut a blade that matches your locks. The chip or fob still has to be programmed at the vehicle, so we need access to the car itself. Where no code is available, we decode a lock instead.
When can you come out to Southern California for a car key?
We work every day from 6:30 a.m. to 11:30 p.m., weekends included. Weekends are included. Call (951) 903-3193 and we'll give you an honest ETA to Southern California based on where we are at the time. If you're stuck outside our hours, it's usually smarter to leave the car parked and locked, get home safely, and call when we open than to pay for an overnight tow.
What happens to the key I lost? Can it still start my Ford?
When we program new keys, we can usually erase lost keys from the immobilizer, which stops them from starting the engine. On some systems the car only remembers the keys present during programming, so the lost one drops off automatically. Keep in mind that a lost key's metal blade can still open the doors, so if it went missing with something that shows your address, ask about rekeying the door locks.
Is the 2017 Ford Taurus push-to-start?
It depends on the trim. Some 2017 Taurus trims have push-button start with a smart key, while others use a turn-key ignition. The quickest way to tell is the start button on the dash, or your VIN, which we can decode when you call.
What battery does a 2017 Ford Taurus key use?
Fobs for the 2017 Taurus use a CR2032 coin cell. Replace it when range drops or the car shows a key-battery warning. If the fob still fails with a fresh battery, the board, buttons or programming may be the problem, which we can test on site.
