Hi does anyone know if locking the driver side door manually trigger the others to lock ? Mine doesn't so it's made the cobra alarm which uses a lock solenoid/motor pretty useless as only the driver side door locks.

 

on mine drivers side locks and unlock all doors and passenger side only locks and unlock that door.

 

As above, and I have a Cobra alarm

 

Thanks guys there's obviously a fault somewhere then. If I can find it at least the cobra remote will lock all doors instead of just the driver side.
