I reluctantly disabled my central locking system and made it a purely manual one years ago by removing the control unit
Repeated problems with door locking motors made me realise that if only one door lock failed in the deadlock position, the only way to get at it would virtually destroy the door card
If the whole system fails when you are outside the car and everything is deadlocked, you are neck deep in the brown stuff.
Unfortunately, removing the control unit also disables the alarm system
