Lost or need to program a new key fob for your 1997 Buick LeSabre? Programming your key fob yourself can save you time and money compared to dealership services. This guide provides step-by-step instructions to program your 1997 Buick LeSabre key fob remote quickly and easily. Whether you have a replacement key fob or are programming an existing one, follow these simple steps to get your remote working again.
Programming Steps:
Before you begin, ensure you have all the key fobs you intend to program for your vehicle. This procedure will program all remotes at the same time.
-
Locate the Data Link Port Connector. The Data Link Port is essential for initiating the programming sequence. It’s positioned underneath the driver’s side dashboard. You’ll need to get down to floor level and look upwards under the dash to find it. Identify the wider top row of the port to orient yourself correctly. If you are facing the port with the wider row at the top, pin 1 will be at the upper left corner and pin 8 at the upper right corner. Crucially, verify that metal pins are present inside ports 8 and 4. Refer to the diagram below for visual guidance on pin locations. Note that the connector itself does not have numbers; they are for reference in the diagram.
-
Bridge Pin 8 and Pin 4. Using a jumper wire, create a connection between pin 8 and pin 4 of the Data Link Port. A small piece of wire or a U-shaped paper clip works effectively for this. Keep the jumper wire connected throughout the entire programming process.
-
Turn the Ignition to the ON Position. Insert your key into the ignition and turn it to the “ON” position. Do not start the engine. Upon turning the ignition to ON, the vehicle will automatically signal that it has entered programming mode by locking and then unlocking all doors. This lock and unlock sequence confirms that the system is ready for key fob programming.
-
Program the First Key Fob. Take your first key fob remote 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 again respond by locking and unlocking the doors. This second lock/unlock cycle indicates successful programming of the key fob. Release the LOCK and UNLOCK buttons on the remote after this confirmation.
-
Program Additional Key Fobs (Within One Minute). If you have more key fobs to program, you must repeat step 4 for each additional remote within one minute of programming the first one. This includes reprogramming any existing, working key fobs to ensure they continue to function.
-
Remove the Jumper Wire. Once you have programmed all desired key fobs, remove the jumper wire that is connecting pin 8 and pin 4 from the Data Link Port.
Following these steps should successfully program your 1997 Buick LeSabre key fob. If you encounter difficulties or prefer professional assistance, you can search for local key fob programming services online.
