Can someone tell me how to deactivate the factory alarm on a 1989 560 SEL? It goes off sometimes even when all the doors, hood & trunk are closed. I just want to disconnect the alarm so it never works. The battery has been run down several times when the alarm went off and there was no one to stop it. Thanks!
