I've been having this problem where the door will not unlock. When i turn the key nothing happens. This only happens occasionally. To unlock, i have to start the car then unlock from the outside (cannot even pull up the door knob) and all the doors will unlock.I sent it for repair, took the workshop three days, they said the alarm was causing the problem and disconnected it. It worked for about 3 weeks and now the problem is back. Should i change the lock? or is it really an electrical problem? where should i send for this problem ( I lost faith in the original workshop)</blockquote>
