The Chrysler Crossfire, manufactured from 2004 to 2008, was designed to be one of the centrepieces of the redesigned Chrysler line-up. It was factory equipped with many advanced electronics, including an antitheft system. However, the antitheft system may require some adjustment for it to function correctly. Fortunately, the process for troubleshooting the Crossfire antitheft system is straightforward and can be completed without any tools or equipment.
Ensure that the doors, hood, decklid and rear liftgate are properly closed. The alarm cannot properly arm if any of the doors or other openings are not closed.
Replace the batteries in the key fob to ensure that the remote is capable of arming the alarm system. If the batteries have been dead for more than a few minutes, the fob will need to be synchronised with the vehicle to function. To synchronise the remote with the car, aim the remote at the vehicle and press the lock or unlock button twice. Next, place the key in the vehicle's ignition and turn the ignition switch to the "On" position. All of the steps must be completed within 30 seconds.
Verify that the parking lamps flash three times when the system is armed using the remote. Alternatively, verify that the alarm is armed by looking at the alarm indicator on the dash. If the alarm is properly armed, the alarm indicator light should blink.
