According to Edmunds.com, Chrysler first released the PT Cruiser in 2001. PT Cruiser owners who need replacement factory keyless remotes for their vehicles can purchase them from a Chrysler dealer or online from keylessride.com. Remotes purchased directly from Chrysler will be programmed by the dealer but may be more expensive. Remotes purchased online will cost less but will require programming before use. The programming process for factory remotes can be done by the vehicle owner but requires the owner to have a working keyless remote.
Insert the key into the ignition and turn the key to the "run" position. The "run" position is the position located immediately before the "start" position that starts the vehicle.
Press and hold the "unlock" button on the working keyless remote for 4 to 10 seconds. While holding the "unlock" button, press and hold the "panic" button on the working remote for 1 second. Release both buttons simultaneously. If done correctly, a chime will sound for 3 seconds indicating the vehicle has entered remote programming mode. If the chime does not start, repeat the tasks in this step to enter programming mode.
Press any button on each keyless remote that needs programming within 30 seconds of entering programming mode. A chime will sound after each remote is successfully programmed.
Turn the key in the ignition to the "off" position and remove the key to exit remote programming mode. Test each remote by locking and unlocking the door locks on the vehicle.
If a working keyless remote is not available, contact an automotive locksmith or bring your new remotes to a Chrysler dealer for programming. It is recommended that all remotes, including older working remotes, be programmed while in programming mode.
