i have faulty central locking which the doors either lock themselves or if you lock them you cannot open them without fidding with the key in the lock and if you cannot manage to open you have to get in through boot which sets alarm off . what i need to know is there any way i can deactivate the alarm and also deactivate the central locking or get a new central locking kit if so how much will this cost, basicaly it is doing my nut in
