Ford s-max 2012 proxy key
I`ve replaced the BCM, I read the old BCM using forscan and write the file to the new BCM. But now i have problems with the key "proxy key" , the key will lock and unlock the car via remote when i press the start button the dash will light up and take the steering lock off. But the engine wont crank and says on the dash key not detected ??? If i put the key out side of the car and press the start button nothing happens, so the car must be seeing the key for the dash too light up when the key is in side of the car. Put the old BCM back in and the keys work fine.

Things i`ve tried.
Deleting Keys and reading them, Two Keys
Help please Thank you.

The "new" BCM is a used version?
Is it a Ford OEM version?
Does the part number match or fit your exact model?
Why was the BCM replaced and what are the original faults?

Hello thank you for your reply.
yes it is a used BCM
part Numbers are the same.
BCM was water damaged but work car stated and run the thing was the drivers side headlight stopped on even if the car was switched off.

So this is a Euro model and likely you need the out-in code.
Have a look at this link:
