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.
2. 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.
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.
