1st you'll need the permanent code. The most likely place to find it is on the right trunk support arm, on a small label.
Then read the following.
Unlocking the door with the keyless entry system
In vehicles equipped with a Keyless Entry system, you can lock or unlock the vehicle doors and open the trunk without using a key. The system will work with up to four transmitters. The manufacturer provided the computer code that operates the system in three places:
on the owner's wallet card
taped to the right hinge of the trunk lid
taped to the computer module in the trunk
When the system is activated, the illuminated entry system turns on the interior and keyhole lights for 25 seconds and the buttons on the keypad light up.
Before unlocking the trunk or passenger door(s) you must unlock the driver's door. If you let more than five seconds pass between pressing numbers on the keypad, the system will shut down and you will have to enter the code again.
To unlock the driver's door, enter the factory code or your personal code. All codes have five numbers. After pressing 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.
To unlock the trunk, press the 5 / 6 button within five seconds of unlocking the driver's or passenger's door, or re-enter the code to open the driver's door, then press 5 / 6.
Locking the doors with the keyless entry system
The Keyless Entry system can also be used to lock the vehicle doors. You can also use the Autolock feature to automatically lock the doors after entering the vehicle.
To lock all of the car doors at the same time, press 7 / 8 and 9 / 0 at the same time. It is not necessary to first enter your keypad code. This will arm the anti-theft system (if so equipped).
AUTOLOCK (With Keyless Entry)
The Autolock feature (if equipped) will automatically lock both doors when:
the vehicle doors are fully closed
the ignition key is turned to the ON position
someone is sitting in the driver's seat or a heavy object is placed on it and
you shift through Reverse
The Autolock feature will repeat when:
the ignition key remains in the ON position
someone remains sitting in the driver's seat or a heavy object is on the seat, and
a door is opened and then closed.
Using the buttons for the keyless entry system can deactivate the Autolock feature.
To deactivate the Autolock system:
Enter the permanent five-digit entry code (not the personal code you may have set).
Within 5 seconds, press and hold 7 / 8.
Within 5 more seconds, press and release 3 / 4.
Release 7 / 8.
To reactivate the Autolock feature, simply repeat the instructions for deactivating the system. The Autolock feature can be turned on and off using these instructions.
Programming your own entry code
You can program a personal code to unlock your vehicle. This code does NOT replace the permanent code, but you can use the personal code in the same manner as the original code.
To program your own code:
Select five digits for your personal code.
Enter the permanent code.
Within five seconds, press 1 / 2.
Within five more seconds, enter the personal code you have selected, pressing each digit within five seconds of the last digit.
The keyless system registers this second code. To unlock your vehicle, you can now use either code. However, the module remembers only ONE personal code at a time. Entering a second personal code will erase the first one and replace it. To erase your personal code:
Enter the original permanent code.
Press 1 / 2 within five seconds.
Wait six seconds.
The Keyless Entry system automatically erases your personal code. The system will now only respond to the permanent code.
*It is recommended that a code not be set that represents numbers in sequential order, or uses the same button repeatedly.
Arming / disarming / resetting the 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 alarm when you enter in the five digit code to unlock the driver's door. The remote entry system is designed to work with the factory installed anti-theft system. It may not work with other anti-theft systems.
Memory Seat Feature (If equipped)
The vehicle allows the remote keyless entry system to control the Memory Seat Module. With this feature, each of the first three transmitters programmed will recall a different seat position (the program only allows three memory positions). When unlocking a vehicle equipped with the programmable Memory Seat/Outside Rear View Mirrors feature, the seat and the outside mirrors will adjust to position that is set for the transmitter being used.
Pressing the transmitter UNLOCK button once will unlock the driver's door and move the seat to its corresponding memory seat position. You may change seat positions at any time. Once programmed, Transmitter #1 will always move the seat to position #1, transmitter #2 will always move the seat to position #2, etc. The feature is turned on at the factory, but you can deactivate the system by using the buttons for the keyless entry system if you do not want to use the feature.
To deactivate the Memory Seat feature:
Enter your permanent entry code (not any personal code you may have selected).
Within 5 seconds, press and hold 7 / 8.
Within 5 more seconds, press and release 5 / 6. Release 7 / 8.
To reactivate the Memory Seat system, simply repeat the instructions for deactivating the system to reinstate the feature.
NOTE: The Memory Seat function will continue to work from the door switch even when deactivated at the remote keyless entry module. Only remote seat recall can be deactivated.
