1️⃣ Insert the new Key Fob in the ignition and turn to the RUN position.

If the vehicle is equipped with Keyless Enter-N-Go, remove the Engine START/STOP button. Then insert the new Key Fob in the ignition and turn to the RUN position.
EVIC will display message: ‘Key Not Programmed’.

2️⃣ Establish a connection with the vehicle, and run ‘Read PIN Code’ Routine.

You can find it in Diagnostic -> WCM -> Routines. The PIN code will be needed when programming the new Key Fob.

👉 How to read PIN Code

3️⃣ Run ‘Program Ignition Keys or Key FOBs’ routine

On the first step you will see the number of currently programmed keys. Usually can be a maximum of 8.

In the second step, you have to enter the 4-digit PIN code.

Then the ignition module will start the Key Fob programming procedure. It may take several seconds.

After a while you should see the programming result and the number of currently programmed key fobs – one more than before 👌

4️⃣ If the vehicle is equipped with a Keyless Go

and the programmed key supports this function (cheap replacements usually do not support it) – 👉 PEM Replace Routine should be run. You can find it in Diagnostic -> PEM -> Routines.

⚠️ Common causes when the ignition module is unable to program the key:

– wrong key fob type – similar looking key fobs are not interchangeable,
– the key fob was already programmed to another vehicle,
– the maximum number of programmed keys has been exceeded,
– too low or too high key fob battery voltage – should be around 3.3 Volts

Do I have to reprogram my key fob if I change the battery?

Typically, you do not need to reprogram the key fob after changing the battery. However, if you've replaced not just the batteries but also some of the internal wiring and electronics, you may need to reprogram it by pairing it with your vehicle once again.
