Hi!

Writing on behalf of my father and his car. A while ago he had the car at the mechanics and they replaced the car battery. After that the key won't unlock the car, nor the boot of the car, and the the roof won't come down.
We have tried two different ways of synchronizing the key to the car, one where you press down unlock and lock, then double click unlock, and then turn the key in the ignition while pressing unlock.
The other way was starting the car, turning it off, pressing five times on unlock, turning the key and pressing five times again. Both ways have been unsuccessful.
Any ideas?
