Re: 2005 C4 key replacement
Thanks for explaining me this. So in our case mobile locksmith replaced transponder. Well added new one because now the original key starts the car only with added transponder. But then WHY it is not locking/unlocking the doors if same key was able to d othis even when the transponder was damaged and key was unable to start the car. After the locksmith added transponder end reprogrammed the key, locking function was lost and he was scratching his head without any logical explantaion...

As I mentioned - it really does depend on the type of system you have - they can differ slightly - so as you can see on some the electronics send out different codes depending on the function - and as long as the fob is authorised (programmed) the remote functions should work.
The coded message sent to the receiver (in the car) by each remote control is composed of the following codes:
The coded message sent to the receiver (in the car) by each remote control is composed of the following codes:
- A fixed code linked to the key
- A rolling code matched with the vehicle’s receiver
- A code corresponding to the action to be performed
- A code corresponding to the condition of charge of the batteries

As long as the new key will start the car then I would try resynching again.
As I get older I think a lot about the hereafter - I go into a room and then wonder what I'm here after.
