Anti-Theft Alarm And Flat Battery
Posted 16 February 2012 - 12:38 PM
I discovered the "flat battery" problem when I could not even open the doors. The wireless remote unlock wouldn't work.
So (almost without thinking!) I opened the drivers' door with the key. It opened. There was no alarm or anything. I put the key into the ignition and turned it on. Nothing. Then I looked at the interior light. Nothing. So I jumped to the conclusion that the battery was flat, and went on to try to charge it.
I have since been re-reading the manual, and find that it says that - if the car is locked with the remote (which mine was) and then is opened physically with the key, the anti-theft alarm will go off. Mine didn't.
Obvious question - if the battery was totally flat, would this in fact mean there is insufficient power even to set off the alarm? Or is there some sort of back-up power for the alarm? If so, why didn't mine go off when I opened the door with the key?
So I am now wondering - has something gone wrong with the alarm/immobiliser set-up - and if so have I inadvertently made the problem worse by trying to charge, and then disconnecting, the battery?
Have something to contribute?

When I had my Gs300 I also had a flat battery problem and although the alarm didn't go off the engine was immobilised.
It was from information like yours on the forum I was able to reset the system and finally get the Mother-in -Law home!
