2015 Ford Expedition Key Replacement

The 2015–2017 Expedition uses the same key setup, so everything on this page applies to those years too. The full picture is on the Ford Expedition key guide.

2015 Ford Expedition: key facts

Key type: Remote-head key

What kind of key does a 2015 Expedition use?

The 2015 Expedition uses a remote-head key. That means the metal blade, the transponder chip and the lock/unlock remote are all built into one piece, so there is no separate fob to carry. The chip inside is a 4D63 80-bit transponder, the family Ford calls ID83. The truck is not a push-to-start model in the standard setup, so you turn a key in the ignition to start it.

For you as the owner, this matters in three ways. First, a blade cut alone will open the door and may even turn the ignition, but the engine will not run until the truck reads a programmed chip. Second, the chip and the remote are programmed separately, so a replacement key needs both done to be fully useful. Third, because programming for this setup goes through the OBD port, the work can usually be done at the vehicle without towing it anywhere.

If you are weighing options for the wider model line, our Ford Expedition key page covers how the setup changes across years, and the Ford key overview covers the brand.

Duplicate key or all keys lost: how each works on this truck

If you still have a working key, making a duplicate is the more straightforward job. For this setup an original key is needed to copy from, so bring the one that still starts the truck. We cut the blade, program the 4D63 chip to the vehicle, and pair the remote buttons.

If every key is gone, that is still possible to solve on this truck. All-keys-lost work on a 2015 Expedition can be done through the OBD port, and the data for this setup does not call for the special NASTF SDRM access that some other vehicles require. It involves more steps than a duplicate, because the blade has to be cut without an existing key to copy, and the truck has to be taught the new chip from scratch. We can do this at your location with a mobile van, or you can bring the vehicle to our Westwood storefront if it is drivable.

Working key available: duplicate from the original, then program chip and remote.
No working key: all-keys-lost process, blade cut to the vehicle, new key programmed by OBD.
A mechanical backup key exists for this setup, which is a good reason to keep a spare in a safe place rather than waiting for a lockout.

What affects the cost of a 2015 Expedition key?

We do not quote numbers on a web page, because the honest answer depends on the situation. These are the factors that move the cost up or down:

Duplicate versus all keys lost. A copy from an original key is usually the more economical route; all-keys-lost involves more labor.
How many keys you need made, and whether you want the remote functions on each.
Your location. A van coming to you costs more to run than a drop-off at the storefront.
Time of day. Late-night and holiday calls take more of our schedule than daytime appointments.
Condition of the old key. A cracked shell or worn buttons can sometimes be dealt with differently from a completely new key, depending on what is still working.
Condition of the ignition. On high-mileage trucks, worn ignition lock wafers can add work if the key will not turn smoothly.

Common problems and what we confirm by VIN

The problems we hear about on this setup are fairly consistent: cracked remote-head key shells, worn buttons, battery failure in the key's remote, and the PATS theft light flashing when the engine cranks but will not start because the chip is not being read. Worn ignition lock wafers also show up on high-mileage trucks. A flashing theft light is not always a dead chip, so we check before replacing anything.

One caveat. The fitment data we rely on shows the 4D63 80-bit chip on the integrated remote-head keys, and it also notes that a smart fob was optional on upper trims. If your Expedition is one of those, the key setup may not match what is described above. That is why we confirm by VIN, or by looking at the truck in person, before cutting or programming anything.

Frequently asked questions

Is the 2015 Ford Expedition push-to-start?

In the standard setup, no. It uses a remote-head key turned in the ignition. The fitment data notes a smart fob was optional on upper trims, so we confirm by VIN if you are unsure what your truck has.

What chip does a 2015 Expedition key use?

The verified data shows a 4D63 80-bit transponder chip, also called ID83, built into the remote-head key.

Can you make a key if I lost all of mine?

Yes. All-keys-lost work is possible on this truck and is done through the OBD port. It takes more steps than copying an existing key, so expect it to be a bigger job.

Do I need my original key to get a duplicate?

For this setup, yes, an original key is needed to duplicate from. If you do not have one, the job becomes an all-keys-lost job.

My theft light is flashing and the engine will not start. Is the key bad?

That pattern, with the engine cranking but not starting, usually means the truck is not reading the chip. It can come from a damaged key, a weak signal, or an ignition issue, so we test before we replace anything.

Will you come to me, or do I need to bring the truck in?

We do both. Mobile vans can come to you across the 140 cities we serve in Los Angeles and Ventura counties, or you can come to 10740 Wilshire Blvd in Westwood.

We cover all these cities
