Are you having trouble with your 2009 Buick Lucerne Key Fob, or do you need to program a new replacement? Programming your key fob can often be done easily at home, saving you a trip to the dealership. This guide provides step-by-step instructions for programming a 2009 Buick Lucerne key fob, ensuring you regain full remote access to your vehicle.
There are two procedures for programming your key fob, depending on whether your Buick Lucerne is equipped with a driver information center (DIC). Vehicles with a DIC will have buttons on the steering wheel, including one with an “i” symbol. Follow the procedure that corresponds to your vehicle’s features.
Procedure #1: Vehicles With Driver Information Center (DIC)
If your 2009 Buick Lucerne has a driver information center, follow these steps to program your key fob:
-
Ignition Position: Insert your key into the ignition and turn it to the “On” position. Do not start the engine.
-
Access Relearn Remote Key Menu: Press the “Information” button on your steering wheel repeatedly until you see “Relearn Remote Key” displayed on the DIC screen.
-
Initiate Learning Mode: Press the “Set/Reset” button (often marked with a checkmark symbol) until “Remote key learning Active” appears on the DIC screen. The vehicle is now in programming mode, ready to learn your key fob.
-
Program Key Fob: Press and hold both the “Lock” and “Unlock” buttons simultaneously on the key fob you are programming. Continue holding until the vehicle chimes twice. This chime indicates that the key fob has been successfully programmed. Repeat this step for each additional 2009 Buick Lucerne key fob you need to program.
-
Exit Programming Mode: Turn the ignition key to the “Off” position to exit the programming mode. Test each programmed key fob to ensure it is working correctly.
Procedure #2: Vehicles Without Driver Information Center (DIC)
If your 2009 Buick Lucerne does not have a driver information center, use this procedure:
-
Ignition Position: Insert the key into the ignition and turn it to the “On” position, without starting the car’s engine.
-
Access Relearn Remote Key Menu: Press and release the trip odometer reset button located on the instrument panel until “Relearn Remote Key” is displayed in the area where the odometer reading is usually shown.
-
Initiate Learning Mode: Press and hold the trip odometer reset button until “Remote Key Learning Active” is displayed. The vehicle is now ready to learn the new key fob.
-
Program Key Fob: On the key fob to be programmed, press and hold the “Lock” and “Unlock” buttons at the same time. Keep holding them until the vehicle chimes, signaling successful programming. Repeat this step for any additional 2009 Buick Lucerne key fobs.
-
Exit Programming Mode: Turn the ignition key to the “Off” position to finalize the programming process. Verify that all programmed key fobs are functioning as expected.
