Hopefully someone may have a tip for me.
Just purchased a new to me Cayenne and have 2 keys supplied with the car.
The spare one had a flat battery as the led didn't light,so replaced the battery and now the led flashes,also used the shops meter to test its sending signals and it is.
But it does nothing on the car,won't unlock or lock or put ignition on?
Main key works fine.
On the nav screen it says only 1 key.
Do the keys have to be resynced to the car or is it more likely the spare key has never been coded to the car with it saying only 1 key synced.
