cunningfox69 10 Posted December 5, 2011 Hi, I'm having an issue with my central locking, it will only lock the car and not unlock it from the key fob, i have checked all the wiring and hoses and the system must be operating with air as it locks the system. The handles are de-locked so i can't test it with the key. I have also checked the pump and it works both ways when disconnected from the hose but only locks when its on???????? Could this be a fault with one of the door vacuum units (which I have visually checked), or could it be the central locking control unit? If so where is the unit located? All help gratefully received. Quote Share this post Link to post Share on other sites
