If the alarm system of your Cadillac DeVille is malfunctioning, the first step to take is to attempt to reset the system. A simple reset can often resolve most of the issues you may be experiencing. To reset the system, start by locking all the doors using the key fob and arming the system. Then, proceed to use the physical key in the driver's door key cylinder. Insert the key into the ignition and turn it to the on and off position twice without starting the vehicle. The dashboard light should flash, indicating the system has been successfully reset and is now ready for use. If further alarm problems persist, it is advisable to bring your car to a Cadillac dealership for inspection of the alarm modules.

Engage the ignition for 10 minutes until the service light blinks, then turn off the key and turn it back on for 10 minutes. Repeat this process three times before starting the car.

I replaced the fuse connected to my starter on my 1990 Cadillac DeVille. Initially, the car started right away when I inserted the new fuse. However, it only started once and now it won't start at all.

When I connect the battery to my 1995 DeVille, all the lights and headlights come on, which drains the battery. Additionally, my key is stuck in the car. I tried resetting the new key fob, but it still won't work.
