I am having trouble programming a key less entry remote for a 2002 grand am

“CUSTOMER LEARN” MODE This feature is only available on domestic vehicles or those which have a U.S. country code designator. This procedure requires access to at least two valid Sentry Keys. If two valid Sentry Keys are not available, Sentry Key programming will require the use of a scan tool.
The steps required to program Sentry Keys with two valid Sentry Keys follows:
1. Obtain the blank Sentry Key(s) that need to be programmed. Cut the keys to match the ignition lock cylinder mechanical key codes. 2. Insert one of the two valid Sentry Keys into the ignition switch and turn the ignition switch to the ON position. 3. After the ignition switch has been in the ON position for longer than three seconds, but no more than fifteen seconds, cycle the ignition switch back to the OFF position. Replace the first valid Sentry Key in the ignition lock cylinder with the second valid Sentry Key and turn the ignition switch back to the ON position. The second valid Sentry Key must be inserted within 15 seconds of removing the first valid Sentry key. 4. About ten seconds after the completion of Step #3 , the indicator light will start to flash and a single audible chime tone will sound to indicate that the system has entered the "Customer Learn" programming mode. 5. Within sixty seconds of entering the "Customer Learn" programming mode, turn the ignition switch to the OFF position, replace the valid Sentry Key with a blank Sentry Key transponder, and turn the ignition switch back to the ON position. 6. About ten seconds after the completion of Step #5 , a single audible chime tone will sound and the indicator light will stop flashing and stay on solid for three seconds and then turn off to indicate that the blank Sentry Key has been successfully programmed. The SKREES will immediately exit the "Customer Learn" programming mode and the vehicle may be started using the newly programmed Sentry Key.

NOTE: The Remote Keyless Entry (RKE) Transmitter will also be programmed during this procedure. These steps must be completed in their entirety for each additional Sentry Key to be programmed. If any of the above steps are not completed in the given sequence, or within the allotted time, the SKREES will exit the "Customer Learn" programming mode and the programming will be unsuccessful. The SKREES will also automatically exit the "Customer Learn" programming mode if:

1. It sees a non-blank Sentry Key when it should see a blank.
2. If it has already programmed four (4) valid Sentry Keys.
3. If the ignition switch is turned to the OFF position for more than about fifty (50) seconds.

NOTE: If you attempt to start the vehicle while in “Customer Learn” mode (LED flashing), the vehicle will behave as though an invalid key is being used (i.e. the engine will stall after two (2) seconds of running). No faults will be logged.
NOTE: Once a Sentry Key has been programmed to a particular vehicle, it cannot be used on any other vehicle.

Keyless Entry Keypad FAQ Ford Explorer
The keypad can be operated with the factory set 5-digit entry code
You can use the keyless entry keypad to

• Lock or unlock the doors without using a key.
• Open the liftgate window.
• Activate or deactivate the autolock feature.

Where the code can be found

• This code is located on the owner's wallet card in the glove box
• Is available from your authorized dealer via scan code
• Is marked on the computer module

Computer Module location

• 1995 thru 2001 is located in the jack storage compartment in the rear of your Explorer. First remove the panel to the jack storage compartment. Towards the front of this area you should see a metal box this is your auto-lock module(way up front next to your rear left passenger seat). On the back side of this is your 5 digit code factory preset code. It is hard to get to. To see it you will have to loosen, pull, use a flashlight or a mirror but it can be done.

• 2002 thru 2007 is in the right panel behind the middle row window. It is below the seat belt mechanism. You have to pull out the top plastic panel off, then loosen the lower panel to be able to see the face of the computer module. The code is on a sticker on the face of the module.

Programming a personal entry code The factory set code cannot be reprogrammed but you can create your own 5�digit personal entry code. When pressing the controls on the keypad, press the middle of the controls to ensure a good activation.
Up to three personal entry codes may be programmed to the vehicle. To create your own personal entry code:

• 1. Enter the factory set code.
• 2. Within five seconds press the 1 � 2 on the keypad.
• 3. Enter your personal 5-digit code. Each number must be entered within five seconds of each other.
• 4. Press 1 � 2, 3 � 4 or 5 � 6 to indicate which of the three personal entry code positions you wish to use.
• 5. The doors will again lock then unlock to confirm that your personal key code has been programmed to the module.

Tips:

• Do not set a code that uses five of the same number.
• Do not use five numbers in sequential order.
• The factory set code will work even if you have set your own personal code.
• If you program a code to a position that already contains a set code, the previously-set code will be erased.

Erasing personal code

• 1. Enter the factory set 5�digit code.
• 2. Within five seconds, press the 1 � 2 on the keypad and release.
• 3. Press and hold the 1 � 2 for two seconds. This must be done within five seconds of completing Step 2.

All personal codes are now erased and only the factory set 5�digit code will work.

Anti-scan feature If the wrong code has been entered 7 times (35 consecutive button presses), the keypad will go into an anti-scan mode. This mode disables the keypad for one minute and the keypad lamp will flash.

The anti-scan feature will turn off after

• One minute of keypad inactivity.
• Pressing the UNLOCK control on the remote entry transmitter.
• The ignition is turned to the 3 (ON) position.

Transmitter Programming
No Tools Required
In the event that a transmitter is lost, program the old and the new transmitters into the memory of the remote control door lock receiver. Up to 4 transmitters may be programmed.


Important
Once the keyless entry receiver enters the programming/diagnostic mode, the programming of the first transmitter erases all previous transmitter programming information. You must then program all of the transmitters.

Program only 1 vehicle remote control door lock receiver at a time. If you program multiple receivers simultaneously, the same transmitter could possibly be programmed to more than 1 remote control door lock receiver.


Perform the following steps:

Sit in the vehicle driver's seat.
Remove the ignition key from the ignition lock cylinder.
Close all of the vehicle's doors.
Remove the MALL PGM fuse from the fuse panel. Refer to Electronic Diagnosis in Body and Chassis.
Turn the ignition lock cylinder to the ACC position.
Turn the ignition lock cylinder OFF, then back to ACC within 1 second.
Open and then close any vehicle door. You will hear a chime when the remote control door lock receiver enters the programming/diagnostic mode. If you do not hear a chime, start again at step 1.

Important
After 7 seconds, you may hear a chime confirming successful synchronization. After approximately 14 seconds, you will hear a chime confirming successful programming.


Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for 14 seconds.
Repeat step 8 in order to program each additional transmitter.
Remove the ignition key from the ignition lock cylinder.
Install the MALL PGM fuse back into the fuse panel. Refer to Electrical Diagnosis in Body and Chassis.
Validate that all the transmitters that were programmed operate properly. Refer to Keyless Entry System Operation
