2019 Ford Transit — Key Fob Programming

Quick reference

Step-by-step on-board programming

The 2019 Ford Transit allows for on-board programming of new smart key fobs, but only if you have two already programmed smart keys for the vehicle. If you have only one working smart key, or no working smart keys, you will need to seek assistance from a Ford dealership or a qualified automotive locksmith with specialized diagnostic equipment.

To program a new smart key fob (requires two existing programmed smart keys):

1. Take your two previously programmed smart keys and the new, unprogrammed smart key into the vehicle.
2. Place the first existing programmed smart key in the backup slot (this is usually in the center console or under a rubber mat, refer to your owner's manual for the exact location).
3. Press the ENGINE START/STOP button. Wait a few seconds, then press the ENGINE START/STOP button again to turn the vehicle off. Remove the first key from the backup slot.
4. Within 5 seconds, place the second existing programmed smart key in the backup slot.
5. Press the ENGINE START/STOP button. Wait a few seconds, then press the ENGINE START/STOP button again to turn the vehicle off. Remove the second key.
6. Within 5 seconds, place the new, unprogrammed smart key in the backup slot.
7. Press the ENGINE START/STOP button. The security light should illuminate and then turn off, indicating successful programming. If not, wait a few seconds, then press the ENGINE START/STOP button again to turn the vehicle off and repeat this step.
8. Remove the new smart key. Test all functions of the new smart key (lock, unlock, remote start if applicable, and starting the engine).

If the programming is unsuccessful, ensure you are following the steps precisely and that your new smart key is compatible with your 2019 Ford Transit.

Battery replacement

The smart key fob for your 2019 Ford Transit uses a CR2450 coin cell battery. To replace it:

1. Locate the small release button or tab on the side or back of the fob. Press it to release the emergency key blade, and pull the blade out.
2. With the emergency key removed, you will typically see a slot or seam where the two halves of the fob meet. Use a thin, flat tool (like a small screwdriver or a coin) to carefully pry the two halves apart.
3. Gently remove the old CR2450 battery, noting its orientation (typically positive side up).
4. Insert the new CR2450 battery with the positive (+) side facing the same direction as the old battery.
5. Carefully snap the two halves of the fob back together until you hear a click.
6. Reinsert the emergency key blade.
7. Test the fob's functions to ensure it's working correctly.

Where to buy a replacement fob

Ford Dealership:

• Pros: Guaranteed genuine OEM part, often includes programming and key cutting in the price, covered by warranty.
• Cons: Most expensive option. Expect to pay anywhere from $250 to $400+ for the fob, cutting, and programming.

Automotive Locksmith:

• Pros: Often more affordable than a dealership, can provide OEM or high-quality aftermarket fobs, offers mobile services, can cut and program the key on-site.
• Cons: Quality of aftermarket fobs can vary, so ensure the locksmith uses reputable brands. Prices typically range from $180 to $300.

Online Retailers (e.g., Amazon, eBay, dedicated key fob websites):

• Pros: Cheapest option for the fob itself.
• Cons: You only get the fob. You'll still need to pay extra for key cutting and programming by a locksmith or dealership, which can negate some of the savings. There's also a risk of purchasing counterfeit or incompatible fobs. Prices for the fob alone can be $70-$150, but remember to factor in programming and cutting costs.

If on-board programming isn't supported

As mentioned, if you do not have two working smart keys, or if you need to program an entirely new smart key system (e.g., all keys lost), the on-board procedure will not work. In these scenarios, special diagnostic equipment is required to communicate with the vehicle's immobilizer system.

• Cost Expectations: A Ford dealership or an automotive locksmith will charge for their time and the use of their specialized scan tools. Expect costs to be in the range of $100-$150 for programming services alone, in addition to the cost of the key fob itself and key cutting. Total costs can easily reach $250-$400+ for a new fob, cutting, and programming when on-board programming is not an option.
• Immobilizer Transponder: The 2019 Ford Transit uses an advanced immobilizer system. The smart key fob contains a transponder chip which must be correctly programmed to the vehicle's immobilizer. Without the correct transponder programming, the vehicle will not start, even if the remote functions (lock/unlock) work.
