    Central locking

    Hi

    Help I have a MK4 2005 Astra the central locking keeps locking itself when I try to open it, it will do this about five times before unlocking, locking is no problem only when I unlock on doing this the indicator lights will flash and the horn will go off until about the fifth time, also sometimes when it does unlock the red light by the lighter is still flashing I then have to wait about 45 seconds to be able to lock the car and then it will unlock no problem.

    Welcome mate

    Will it unlock first time with the key in the door? This may just be a faulty drivers door motor

    Hi

    Thanks for replying no the cenral locking still locks itself even if I try to open the doors with the keys in in the door, the only thing that has happen since I have had the car to this happening was an MOT and two new front tyres but the problem did not start until two weeks after this was done, could a relay cause this kind of problem im not sure,

    Thanks again Kevwally

    The relay could be the problem but i'd expect it to be a wiring issue or maybe a faulty switch in the drivers door.

    Hi Again,

    Thanks for your help I'm going to try the cheap option first and check the relay so my next question is do you know which relay would do the central locking on an Astra MK4 2005 1.6 sport twinport.

    yet again many thanks for your time

    The relay is in the drivers kickpanel. When you replace it any remote for the car will need reprogramming in by vauxhall

    Hi

    Got it sorted thanks all I needed to do was to undo the power from the car battery for a minute then replace it and it was back to normal must have been a problem in the chip or something.

    Thanks
