Unlocking the Doors with the Keyless Entry System You must unlock the driver's door before you unlock any of the other doors or trunk. If you let more than five seconds pass between pressing numbers, the system shuts down, and you have to enter the code again. The system has shut down if the keypad light is out. If the keyless entry system does not work properly, use the key or transmitter(s) to lock and unlock the doors or unlock the trunk. 1. To unlock the driver's door, enter the factory code or your personal code. All codes have five numbers. After you press the fifth number, the driver's door unlocks. To unlock the passenger's door, press the 3/4 button within five seconds of unlocking the driver's door or trunk, or re-enter the code to open the driver's door, then press 3/4. 2. 3. To unlock the trunk, press the 5/6 button within five seconds of unlocking the driver's or passenger's doors, or re-enter the code to open the driver's door, then press 5/6. As long as the driver's door has been unlocked first, you can open the passenger door or the trunk in any order. Locking the Doors with the Keyless Entry System Along with unlocking your doors, you can use the keyless entry system to lock the doors. You can also use the Autolock feature to automatically lock the doors after you get in the vehicle. To lock all of the vehicle's doors at the same time, press 7/8 and 9/0 at the same time.
