Remote Programming for most Code Alarm systems post 1993
Open the driver’s door.
Turn the ignition key ON (turn key all the way forward without starting vehicle).
Press and Hold the programming/override button (located under dash). In approximately 20 seconds the system will start to cycle the door locks and siren (if equipped) 3 times to indicate the system has entered the transmitter learn mode (Do not release the programming/override button).
Press the #1 button on the un-programmed transmitter. The system will respond by cycling the door locks and the siren (if equipped) one time to indicate the transmitter has been learned.
All other transmitters (up to four) also need to be programmed at this time.
Programming is now complete, let go of the programming/override button and turn ignition off to exit learn mode.

Remote Programming for all Code Entry pieces (Z-7, Y-5 and Y-7)
Obtain the TWO or FOUR digit code off the module. The Code will be located in the following locations:
  • Placed on a sticker on the back side of the module labeled “Code#”.
  • Located on the portion of the circuit board beneath the spade connectors. There will be two rows of 1-5. Which ever number is shaded in BLUE in each row is the CODE number for that module.
Make sure the system is disarmed and the ignition is off.
Without starting the vehicle, turn the ignition ON, OFF then ON at ½ second intervals.
After two seconds the status indicator will begin flashing for Code Entry.
Allow the status indicator to flash the corresponding number of times as the first number in the code. Turn ignition OFF. The first number has been entered.
Turn ignition back to the ON position. The status indicator will again begin flashing. Repeat the previous step, this time using the second digit of the Code.
Repeat previous steps if unit is equipped with a four digit code (Z-7).
If correct code has been entered, the siren will chirp twice indicating entry into Transmitter Programming Mode.
Wait 5 seconds and then press button #1 on the un-programmed transmitter.
All other transmitters (up to four) also need to be programmed at this time.
Programming is now complete. To exit programming mode turn the vehicle ignition ON then OFF.
Remote Programming for all Code Alarm systems prior to 1993
Enter the vehicle and close all doors.
Wait until dome light has shut off.
Perform the following three steps (all within 5 Seconds):

The door locks (if equipped) and siren (if equipped) will cycle 3 times to indicate the module has entered Transmitter Learn Mode. If the system did not cycle 3 times repeat the above step by using the driver’s door pin switch.
Press button #1 on the un-programmed transmitter.
All other transmitters (up to four) also need to be programmed at this time.
Programming is now complete. Turn ignition off to exit Transmitter Learn Mode.
If you don’t know what a valet switch/button is or you can’t find it then visit this webpage: http://www.remotesandkeys.com/kb_results.asp?ID=1
Alarm must be disarmed to enter programming mode. Valet mode won’t work. The red LED must be off. If there is no working remote and the alarm sounds when you open the door or start the vehicle then do the following: Press valet switch for one second and release with the ignition ON. If that doesn’t work then do it with ignition OFF.
