2020 Ford Expedition Key Replacement
Short answer: The 2020 Ford Expedition belongs to the Expedition Fourth generation and uses a smart proximity key with push-button start and a flip key. Its immobilizer chip: Hitag Pro ID49. 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 Expedition keys on site; call (951) 903-3193 with your VIN for a quote.

A 2020 Ford Expedition key is more than a piece of cut metal. Depending on the trim, it carries a transponder chip that talks to the immobilizer, a remote that operates the door locks, or a proximity fob that lets the engine start with a push of a button. Each piece has to be matched and programmed, not just copied. Julian's Locksmith handles that work on-site in Southern California and the surrounding parts of the Inland Empire: we identify the exact key by VIN and part number, cut the blade by code, and pair the electronics through the car's diagnostic port. Below, you'll find the key types used on the Expedition, what replacement involves, and what affects the cost.

The aluminum-body 2018 Expedition and the long Expedition Max start with a button in nearly every case, using slim Hitag Pro smart fobs with an HU101 emergency blade. Catalogs list a four-button 315 MHz fob with a liftgate button (Ford 164-R8197, FCC ID M3N-A2C931423) and a five-button 902 MHz fob with remote start (Ford 164-R8198, FCC ID M3N-A2C931426). Ford's three-button flip key is also listed for these years, for the less common trucks built with a turned ignition.
What's specific to the 2020 Expedition
The 2020 Ford Expedition is the third of 5 model years in the Expedition Fourth generation (2018–2022), so it shares its key system with the rest of that run, which makes replacement parts easy to source.
A 2020 Ford Expedition is about 6 years old now. Original fob batteries are near the end of their life at this age, so weak range or a "key not detected" message is often a battery before it is a failed fob. Cars this age are often on their second owner, which is when a single remaining key and a request for a spare tend to show up.
Key options for the 2020 Ford Expedition
- Smart proximity key (push-to-start). Making a new smart key is mostly a programming job. The fob has to match the vehicle's FCC ID, frequency and chip, and then the keyless system must be told to accept it, normally through the OBD-II port. Depending on the platform, that can mean entering a PIN, waiting through a timed security procedure, or on some newer vehicles, using manufacturer online access. When every key is lost, certain models need a module removed and read on the bench. For your Ford Expedition Fourth generation, we'll tell you which of those applies, and if a step is dealer-only, you'll hear it before we drive out. The emergency blade hidden inside the fob is cut by code during the same visit.
- Flip (switchblade) key. The hinge is the weak point on most flip keys. The pivot pin loosens, the spring loses tension, the release button sticks, and eventually the blade either won't lock open or flops out on its own. Carrying the key half-open in a pocket speeds that wear along. If the electronics are healthy, a replacement shell with a new hinge and pin often brings a 2020 Ford Expedition flip key back to crisp action: we transfer the board and chip, move or recut the blade, and test every function. If the board has broken solder joints or water corrosion, we'll show you the damage and quote a new key instead.
How the Ford immobilizer works on the Expedition
- The four- and five-button fobs run at 315 and 902 MHz respectively and can't substitute for one another.
- These fobs take a CR2450 cell, the larger coin battery that replaced the CR2032 in Ford's earlier fobs.
Programming a 2020 Expedition key
Fobs are programmed through the OBD-II port with a tool covering Ford's Hitag Pro security, typically after a timed access period, and the emergency blade is cut on a laser-style machine. A spare is routine with one fob present. With every fob lost, an active alarm can call for an emulator or bypass cable, so we confirm coverage by VIN before quoting and tell you if the dealer is the better route.
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 fobs are routine; all-keys-lost on these Hitag Pro trucks can need an emulator or bypass cable, which we confirm by VIN first.
Lost every key to your Expedition?
- 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.
- 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. 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.
- 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
- 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.
- When you sell or trade in the vehicle, buyers and dealers expect two keys. A missing key can come up during an appraisal or a private-sale negotiation, so having both on hand keeps the conversation about the car, not about what it will cost the next owner to replace one.
- 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?
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 Expedition and your schedule.
Expedition key battery
Battery details for the 2020 Expedition: CR2450 (smart fob); CR2032 (flip key). 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
- Identify the exact key your Expedition uses. We ask a few quick questions on the phone: the year, whether the car starts with a turn key or a button, how many keys you have left, and whether the remote still works the doors. Then we check the VIN against our programming references so the van arrives with the correct blank or fob, not a close guess.
- Verify ownership before any work. California holds licensed locksmiths responsible for knowing whose car they're making keys for. We record your name, the VIN and the plate on a work order. If you aren't the registered owner, you'll need the owner's written authorization along with your own photo ID before we begin.
- 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.
- 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. 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 Expedition, you'll have heard that before we arrived, not halfway through the job.
- 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 Expedition key
- 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.
- Blade style and cutting. The blade still matters on keyless cars, because the emergency insert has to fit the door lock. Cutting by code is standard for us. Decoding a door lock when no key or code exists adds time, and so does progressing any cuts the door lock doesn't show.
- 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
- 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.
- 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.
- When a key's head cracks or its blade bends, replace it before it fails. A transponder chip can slip out of a split head, and a bent blade can break off inside the ignition or door lock, turning a simple key replacement into an extraction and repair job. Small symptoms are the inexpensive time to act.
- 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.
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.

Frequently asked questions
Can a locksmith make a key for a 2020 Ford Expedition?
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 fobs are routine; all-keys-lost on these Hitag Pro trucks can need an emulator or bypass cable, which we confirm by VIN first. The 2020 Expedition uses a smart proximity key with push-button start and a flip key.
How long does it take to make a new Ford Expedition key?
Adding a key to a car that already has a working one is usually a single short visit, often finished within an hour once we're on-site. All-keys-lost jobs take longer because we may need to open the car, decode a lock and run a longer programming routine. Some security systems also impose their own waiting periods during programming. We'll give you a realistic time estimate for your specific vehicle when you call.
What do I need to show before you make a key for my Expedition?
A current registration or title and a government-issued photo ID in the same name. We match the VIN on the paperwork with the one on the dashboard before any cutting or programming. If you're not the registered owner, bring the owner's written authorization and a copy of their ID. If the documents are locked in the car, we'll open it first and check them there.
Can you make an Expedition 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.
Why does my Expedition 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 2020 Ford Expedition resolves it.
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 2020 Ford Expedition push-to-start?
It depends on the trim. Some 2020 Expedition 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 2020 Ford Expedition key use?
Battery details for the 2020 Expedition: CR2450 (smart fob); CR2032 (flip key). 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.
