When Alarm and Central Lock Went South

My central lock did give me some headache for a week or two. Whenever I arm the car using the transmitter, the door will lock and in a split second it will unlock the door back. On top of that, the lock latch on the driver side isn't locking properly which indicate, either the central locking gun has broken or the linkages were screwed. So I took it back to the shop I've bought and installed the alarm. To their finding, actually the wiring was the culprit. I'm quite surprise also since they are known as the one of the best in wiring job (as per claimed in Lyn.net). But then, even the mighty Microsoft did shit (remember Win ME?) They took more that an hour to troubleshoot it. Now everything is working fine.
