How to Disable a Cadillac Alarm

by David Clair

Many Cadillac vehicles are equipped with anti-theft alarm systems that activate an audible alarm and flash a visual alarm when triggered. The alarm system monitors sensors throughout the vehicle to detect possible unauthorized entry attempts. If the alarm system is disabled, the sensors will not trigger the alarms until the system is reactivated. The alarm system can be disabled and reactivated at any time.

Step 1

Press the "unlock" button on the keyless entry remote.

Step 2

Open the glove compartment.

Press the "on" portion of the valet mode switch to activate valet mode. The alarm system is disabled until valet mode is turned off.
