Step-by-step on-board programming
This procedure is for programming the remote portion of a new key fob. It will not program the immobilizer chip. You must have one already programmed key to perform this procedure. If you do not have a working key, you will need to have a new key cut and programmed by a locksmith or the dealer.
- Insert one of the already programmed keys into the ignition.
- Cycle the key from the OFF to the ON position eight times in quick succession (within 10 seconds), with the eighth turn ending in the ON position.
- The doors will lock and unlock to confirm that programming mode has been entered.
- Within 20 seconds, press any button on the new, unprogrammed key fob. The doors will lock and unlock to confirm that the new fob has been programmed.
- If you have any other new fobs to program, repeat step 4 for each one.
- Turn the ignition to the OFF position to exit programming mode. The doors will lock and unlock one last time to confirm.
Battery replacement
The 2021 Ford Transit key fob uses a CR2032 battery. To replace it:
- Use a small flathead screwdriver to gently pry the two halves of the key fob apart. There is a small notch on the side of the fob for this purpose.
- Once the fob is open, you will see the battery. Note the orientation of the positive (+) and negative (-) sides.
- Remove the old battery and insert the new one, making sure it is correctly oriented.
- Snap the two halves of the fob back together.
Where to buy a replacement fob
- Dealer: The most expensive option, but you are guaranteed to get a genuine OEM key fob. Expect to pay $150–$300 for the fob and another $100–$200 for cutting and programming.
- Locksmith: A more affordable option than the dealer. A locksmith can usually provide a genuine OEM or high-quality aftermarket fob and has the tools to cut and program it. Expect to pay $100–$200 for the fob and programming.
- Amazon/Online: The cheapest option, with fobs available for as little as $20. However, the quality can be hit-or-miss, and you will still need to have the key cut and programmed by a locksmith or dealer.
If on-board programming isn't supported
As mentioned, the on-board programming procedure for the 2021 Ford Transit only programs the remote functions. The key blade must be cut to match your vehicle's ignition, and the immobilizer transponder chip inside the key must be programmed to the vehicle's computer. This requires specialized equipment that only locksmiths and dealers have. Expect to pay $50–$150 for cutting and programming services.
