With gm alarms you need to wait about 2 min for it 2 arm. also it only protects the doors when opened.

1997 deville, battery drains overnight,pin pointed to a relay in trunk energized, removed relay, no dash lights.if you remove body 3 50 amp fuse it doesn't drain overnight, but also won't start...

I've replaced several rear body control modules that go bad and drain the battery. It is located behind the seat, black box about 4" x 5" rectangle. You can use a hand held scanner to diagnose them, the ones I replaced did throw a code. It is complicated and you need a pinout chart to diagnose it with an ohm meter. The ones I got were new and ran around $350.00

1998 deville dash says trunk open, does this cause battery to drain overnight?

If the trunk is 'open' ... there is probably a light in the trunk and the light will kill the battery over night ... yes. Adjust the switch to fix this problem.

Thanks for your interest in

1998 cad alarm no start

Your GM product has a safety alarm, it shuts down the radio , or locks it.
I send ours to a GM dealer to get it unlocked. They don't give those codes out.

Car won't start-- warning light

Try removing the fuse for the security system and see if this will allow you to start the car. If not, you have another problem and will need to take it to a mechanic.
