1999 Cadillac DeVille Q&A
1999 Cadillac DeVille Question: My alarm stays on even after starting. How do I turn the Alarm off completely?
IF ITS A FACTORY ALARM YOU REALLY CAN'T DISCONNECT IT WITHOUT EFFECTING SOMETHING ELSE IN YOUR VEH. IF ITS AFTERMARKET HAVE IT REMOVED COMPLETELY - globalhelper
Unlock your trunk or doors with your key. It should turn it off. - robertherndz
