Battery disconnection and alarm

Recommended Posts

I know the procedure for preventing the seperate battery powered alarm going off if the battery is disconnected. That is insert ignition key and turn to position 1 before disconnecting the battery.


I have a question however. If having disconnected the battery using the above procedure - is it necessary to leave the key in position 1, or can the key be withdrawn? The reason I ask is that I intend to do some work on the electrics and this will take me some time, so I don't want to leave the key in the car during this period.

Upnorth...  I'm guessing you can remove the key.  I've always just disconnected the battery without the alarm going off?  I might add if you're going to disconnect the battery I would first lower the door windows a tad so you can open and close the doors without the door glass binding on the door rubber.

creekman - RoW cars have different alarm system than US/Canada cars. There is a special procedure to remove the battery without setting off the car alarm. In RoW cars the alarm horn has it's own separate battery and logic.


Upnorth - yes you can likely remove the key once the battery is out - but you might want to remove/disconnect the alarm horn just in case.

Loren - FYI you can remove the key once the battery has been disconnected. I did it and everything was quiet. Thanks again to your wonderful site. How would we survive without it.


Creekman - thanks for tip on dropping window. Would never have done that. There is some logic in the seperate alarm battery, as a bad person would be expecting the alarm to go off, and would then be ready to disconnect battery to stop it. When it doesn't maybe he would giveup and retreat, leaving the pride and joy to live another day.
