To erase all of the personal entry codes and remote entry transmitters programmed to a vehicle: 1. 2. 3. Enter the original permanent code. Press 1/2 within five seconds of Step 1. Press and hold 1/2 for two (2) seconds. All of the vehicle doors will lock and then unlock to confirm erasure. Do not set a code that presents the numbers in sequential order, such as 1/2, 3/4, 5/6, 7/8, 9/0. Studies show that people who idly press the buttons usually press a sequential pattern. Also, do not select a code that uses the same button five times. Thieves can easily figure out these types of codes. Arming, disarming and resetting your anti-theft system from the keyless entry pad The Keyless Entry system will arm the anti-theft system when you use the 7/8 and 9/0 keys to lock the doors, and will disarm or reset a triggered anti-theft alarm when you enter in the five digit code to unlock the driver's door. Remote Entry System With the remote entry system, you can lock and unlock the vehicle doors and open the trunk without using a key. The buttons for the system are located on the two hand held transmitters that came with your vehicle. The remote also has a personal alarm feature. The system will work with up to four transmitters. Your vehicle came with two transmitters. Additional transmitters can be ordered from your dealer. 110
