C5 central locking

[Davidcrofts]

The locking on the button has decided to fail today. I seem to remember that there is a method for resetting it but can’t remember exactly how. I know it was something about holding the button down?

If you mean re-synch of the remote fob. Turn the key to ignition on then press & hold remote button within 10 seconds IIRC.

Thank you that worked
