2016 Ford Explorer Key Replacement

2016 Explorer key specs

The 2016 refresh moved the Explorer to Hitag Pro keys and the side-milled HU101 blade. Base trucks start with a turned key and a three-button flip key (Ford 164-R8130, FCC ID N5F-A08TAA). Most others use Intelligent Access fobs: for 2016-2017, a four-button fob in 315 MHz form (FCC ID M3N-A2C31243800) or 902 MHz remote-start form (FCC ID M3N-A2C31243300); for 2018-2019, Ford's slimmer fob, FCC ID M3N-A2C93142300, or its 902 MHz counterpart, M3N-A2C931426.

What's specific to the 2016 Explorer

2016 was the first model year of the Explorer Fifth generation refresh. Early-production cars sometimes use different part numbers than later ones, so for a 2016 Ford Explorer we confirm the exact key from the VIN or the old key's FCC ID before cutting anything. It also marks a change from the previous generation: the 2015 Explorer used a remote head key, a smart proximity key with push-button start and a transponder (chip) key, while the 2016 uses a flip key and a smart proximity key with push-button start. Keys from the older car will not work in this one.

At roughly 10 years old, a 2016 Ford Explorer 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 2016 Explorer 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 2016 Ford Explorer

• Flip (switchblade) key. When a flip key is lost rather than broken, the replacement starts from scratch. For a Ford Explorer, we confirm the FCC ID, frequency and chip type from the VIN and any remaining key, cut the blade by code, then program both the transponder for the immobilizer and the remote buttons for the doors. Some platforms accept a new flip key through the OBD-II port in a single session; others need a security PIN or a module read before they'll take a new key. Aftermarket flip keys vary a lot in quality, especially the hinge mechanism, so we'll tell you which options we trust for your 2016 Explorer and which we don't.
• Smart proximity key (push-to-start). A smart or proximity key lets a 2016 Ford Explorer 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.

How the Ford immobilizer works on the Explorer

Ford's immobilizer is PATS, the Passive Anti-Theft System, sold under the SecuriLock name. A transponder sealed in the key head, or built into the fob on push-button models, answers a coded challenge from a coil around the ignition or from antennas in the cabin, and the engine won't run until the powertrain computer accepts the answer. Across 2000-2026 the chip changed in clear steps. Pickups, big SUVs and the Crown Victoria used a fixed-code Texas 4C chip into the early 2000s, and the Excursion kept it through 2005. The first Escape and early Focus used a Texas 4D60. Between 2000 and 2004 most of the lineup moved to the encrypted Texas 4D63, with 80-bit versions becoming the norm around 2011, while most catalogs list the E-Series van with chip keys only from 2008. NXP Hitag Pro arrived with the 2013 Fusion, reached the F-150 for 2015 and now covers nearly the whole lineup. Remote-head keys appeared in the mid-2000s, Intelligent Access push-button fobs around 2010, and long-range 902 MHz fobs came with remote start. Recent models use 434 MHz fobs, and the Mustang Mach-E and F-150 Lightning added Phone As A Key.

• The 2016-2017 fobs take a CR2032, while the slimmer 2018-2019 fobs take a CR2450.
• Catalogs list the three-button flip key, Ford 164-R8130, for Explorers from 2016 through 2022, so one key style covers the base trim of two generations.

Programming a 2016 Explorer key

Flip keys and fobs are programmed through the OBD-II port with a programmer that covers Ford's Hitag Pro system, after a timed security access. We cut the HU101 blade or emergency insert on a laser-style machine. Spares are routine from one working key. With every key lost, an active alarm can call for an emulator or bypass cable, so we confirm coverage by VIN before quoting.

Spare keys are routine; all-keys-lost on these Hitag Pro Explorers can need an emulator or bypass cable, which we confirm by VIN first.

Lost every key to your Explorer?

1. Gather your documents and the VIN. Find your registration or title and a government photo ID in the same name. Note the VIN, which is printed on the driver's side of the dashboard and usually on your insurance card. If the paperwork is locked in the car, tell us; we'll open the vehicle first and check it there.
2. 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.
3. Originate a new key from the car. Originating a key means building it without a sample. The door lock usually reveals most of the cuts; any it doesn't are worked out by test-cutting and trying the ignition or a second lock. The finished blade should feel like a factory key, not a forced fit.
4. Program the key to the immobilizer. All-keys-lost programming often takes longer than adding a key, because the car has no trusted key to authorize the change. We follow the procedure your Ford Explorer requires, then confirm the engine starts and keeps running and the remote or keyless functions respond.
5. 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.
• Electronics fail without warning. A fob dropped on concrete, run through the washing machine or soaked at the pool can quit for good. With a second programmed key, that's an annoyance you fix on your own schedule, not a stranded car that needs attention today.
• 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.

Dealer or mobile locksmith?

Price and parts are the other half of the comparison. Dealers typically sell factory keys only and charge their posted service rates for programming. We offer factory keys where it matters and quality aftermarket alternatives where they perform well, and the quote covers cutting, programming and the trip, with nothing tacked on at the end. Timing differs too. Dealer service departments generally keep business hours, while we take automotive calls every day from 6:30 a.m. to 11:30 p.m., which covers early commutes and late evenings. We're closed overnight, and we'll be upfront if your timing means the dealer or a next-day visit is the better plan. Neither option is wrong; the right one depends on your Explorer and your schedule.

Explorer key battery

Battery details for the 2016 Explorer: CR2032 (flip key and 2016-2017 fob); CR2450 (2018-2019 fob). Swap cells one at a time and match each one exactly; if a key still fails with a fresh battery, the board, buttons or programming may be the problem, which we can test on site.

How the job works

1. Identify the exact key your Explorer 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 Explorer keys that look identical can carry different electronics, so this step keeps the wrong part from ever reaching the car.
2. 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.
3. Get the key code or decode the lock. If you still have a working key, we can read its cuts directly and check them against the factory depths for the Ford keyway. A worn key gets corrected back to spec during this step, so the new key turns crisply instead of reproducing years of wear in a fresh piece of metal.
4. Cut the blade on-site. Our van carries a code-cutting machine that handles both traditional edge-cut blades and the laser-cut, side-milled profiles common on newer keys. The blade is cut to the code, then test-fitted in a door lock and the ignition or emergency keyhole to confirm smooth operation before any programming begins.
5. Program the chip, remote or smart key. Programming tells the car's computers that the new key belongs to the vehicle. Transponder chips are added to the immobilizer, remote buttons to the body control module, and proximity fobs to the keyless system. If a step requires dealer-only access on your Explorer, you'll have heard that before we arrived, not halfway through the job.
6. Test everything and clear out old keys. Before we leave, every function gets checked: doors, trunk or liftgate, panic button, remote range, engine start, and the emergency blade in the driver's door. If keys are missing, we delete them from the car's memory where the system allows, so a lost key can no longer start the engine.

What affects the price of an Explorer 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 Explorer came with different key styles by trim, the one your car actually uses is the one that sets the quote.
• All keys lost or adding a key. On some vehicles, losing the last key changes the programming entirely, from a quick add-key procedure to a full immobilizer reset or a module read on the bench. That extra labor shows up in the price, and it's the strongest argument for keeping a spare in the house.
• 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. Sometimes a key problem is really a lock problem: an ignition that won't turn even with the right key, or a door cylinder that has been jammed for years. Fixing those is separate work. We point them out, explain the options, and quote the whole job up front so the bill holds no surprises.

Call (951) 903-3193 with your VIN and the keys you still have, and we'll quote the job before any work starts.

Common Ford key problems

• Ford fobs come in 315 MHz, 434 MHz and long-range 902 MHz versions, and two fobs that look identical may not be interchangeable. We match the FCC ID printed on your old fob, or decode the VIN, before ordering a replacement.
• A flashing theft light with a crank and no start, or an engine that fires and dies after a second, usually means PATS didn't read the key. A cracked head that lost its chip, or a hardware-store copy with no transponder, is the usual cause.
• Two chip keys hanging side by side, or a metal gadget pressed against the key head, can confuse PATS. Ford's manuals warn about this, and a truck that starts once the extra keys come off the ring has a healthy key.

Tips from a mobile locksmith

• Never hide a spare key or fob on the outside of the car. Magnetic boxes in wheel wells and under bumpers are the first places a thief checks, and with a proximity fob, a hidden key can let anyone open the doors and drive away. Keep the spare at home or with someone you trust.
• 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.
• 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

Before we cut or program a key for any vehicle, we verify that you have the right to it. Please have two things ready: the current registration or the title, and a government-issued photo ID with a matching name. We also check that the VIN on those documents matches the VIN plate on the dashboard. If the registration is locked inside the car, that's fine; we open the vehicle first, check the paperwork in the glove box, and only then make the key. If something doesn't line up, we stop and sort it out before any key is made.
