Locks and Security Programming your own personal entry code To program your own code: 1. Enter factory set code (keypad will illuminate when pressed). 2. Press 1/2 control within five seconds of step 1. 3. Enter your personal 5 digit code. Enter each digit within five seconds of previous one. 4. After the code is entered, the locks will cycle, confirming that the new code has been set. Do not set a code that includes five of the same number or presents them in sequential order. Thieves can easily figure out these types of codes. Your personal code does not replace the permanent code that the dealership gave you. You can use either code to unlock your vehicle. If a second personal code is entered, the module will erase the first personal code in favor of the new code. If you wish to erase your personal code, use the following instructions: 1. Enter factory set code. 2. Press 1/2 control and release. The system will now only respond to the factory set code. 165
