30 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE To Disarm the System: Use the Keyless Entry transmitter or the key to turn the driver's door lock to the unlock position. If something has triggered the system in your absence, the horn will sound three times when you unlock the doors and the security lamp will flash for 30 seconds. Check the vehicle for tampering. The Security system will also disarm, if the vehicle is started with a programmed Sentry Key. If an unprogrammed Sentry Key is used to start a vehicle, the engine will run for 2 seconds and then the security alarm will be initiated. To exit alarming mode, press the transmitter Unlock button, unlock the driver's door using the key cylinder, or start the vehicle with a programmed Sentry Key. The Security Alarm System is designed to protect your vehicle; however, you can create conditions where the system will arm unexpectedly. If you remain in the vehicle and lock the doors with the transmitter, the alarm will sound when you pull the door handle to exit. You may also accidentally disarm the system by unlocking the driver's door with the door key and then locking it manually with the lock plunger. The door will be locked but the Security Alarm will not arm.
