Suprakeith Posted December 16, 2014 Share Posted December 16, 2014 My supra has decided that she doesn't want to lock the doors when arm the car using alarm. I now have to lock both doors using key them arm the alarm. When deactivate the alarm both doors unlock but don't lock when arm alarm. Can anyone please shed any ideas or reason central locking not working properly Link to comment Share on other sites More sharing options...
Dazzi Posted December 16, 2014 Share Posted December 16, 2014 Common problem. There's other threads like this in here. Usually the red control box passenger side behind the dash. Link to comment Share on other sites More sharing options...

Is it just case of getting new one or can old one be repaired? Link to comment Share on other sites More sharing options...
RobUK Posted December 16, 2014 Share Posted December 16, 2014 New/2nd hand one but if the doors are unlocking then it could be the door mechanism rather than the red box Link to comment Share on other sites More sharing options...

Suprakeith Posted December 16, 2014 Author Share Posted December 16, 2014 Thank you for the link, I have found 2nd hand control box will order that and try that 1st if no joy will look at locks themselves, from reading link believe mine to be control box fault as both doors lock fine using key Link to comment Share on other sites More sharing options...
