Step-by-Step Programming Guide for Your 1998 GMC Sierra Key Fob
Here’s how to program your 1998 GMC Sierra key fob:
-
Locate the Data Link Port. The Data Link Port, also known as the OBDII port, is essential for initiating the programming sequence. You’ll find it located under the driver’s side dashboard. It’s important to identify pins 8 and 4 on this port correctly. Note that the port is designed to be wider on the top row, which can help you orient yourself.
-
Prepare to Connect Pins 8 and 4. First, ensure that terminals 8 and 4 of your Data Link Port have metal contact pins. You will need a jumper wire to connect these two terminals. Keep this jumper wire connected throughout the entire programming procedure. Double-check that you have correctly identified terminals 8 and 4. Once you connect the jumper wire, the vehicle should automatically respond by locking and then unlocking its doors. This action indicates that you have successfully entered the key fob programming mode.
-
Program the First Key Fob. Take the first key fob you wish to program and simultaneously press and hold both the LOCK and UNLOCK buttons. Continue holding both buttons for approximately 15 seconds. After about 15 seconds, the vehicle will signal successful programming by locking and unlocking the doors once more. At this point, you can release the buttons on the key fob.
-
Program Additional Key Fobs. If you have more key fobs to program, you must repeat the previous step (step 3) within one minute of programming the first one. For each additional key fob, press and hold the LOCK and UNLOCK buttons together for 15 seconds until the vehicle responds with the lock and unlock signal.
-
завершение Programming. Once you have programmed all desired key fobs, the final step is to remove the jumper wire from the OBDII port. This action will exit the programming mode.
