Lost your 2006 Buick LaCrosse key fob or need to program a new one? As a car repair expert at Keyfobx.com, I understand the frustration of key fob issues. Fortunately, programming a key fob for your 2006 Buick LaCrosse can often be done right at home, saving you time and money compared to dealership visits. This comprehensive guide will walk you through the programming process for your 2006 Buick LaCrosse, whether you have an existing working key fob or not.
Programming Your 2006 Buick LaCrosse Key Fob with a Working Key
This method is the simplest and quickest if you already have a programmed key that works with your Buick LaCrosse. This procedure is designed to add new keys and will not erase any previously programmed keys. Before you begin, ensure that the new key is properly cut to match your vehicle’s ignition.
Here’s how to program your 2006 Buick LaCrosse key fob with a working key:
-
Start Your Engine with the Original Key: Insert your existing, working key into the ignition and start your 2006 Buick LaCrosse engine as you normally would.
-
Turn Off and Remove the Key: Once the engine is running, turn the ignition key to the “off” position and remove the original key from the ignition.
-
Insert the New Key and Turn to “On”: Within 10 seconds of removing the original key, insert the new, unprogrammed key into the ignition. Turn the new key to the “on” position. Do not start the engine at this point.
-
Wait for the Security Light: Keep the key in the “on” position. The security light on your dashboard should turn off once the new key is successfully programmed. It’s important to note that the programming process can be very fast, so the security light might not be illuminated for long. If your 2006 Buick LaCrosse model doesn’t have a visible security light, wait for approximately 10 minutes and 45 seconds to ensure the key programming is complete.
-
Repeat for Additional Keys: If you need to program more than one new key fob, simply repeat steps 1 through 4 for each additional key.
Programming Your 2006 Buick LaCrosse Key Fob for Push Button Start Vehicles
If your 2006 Buick LaCrosse is equipped with a push-button ignition system, the programming procedure varies slightly. There are two scenarios depending on whether you have a working transmitter (proximity key) or not.
Scenario 1: Programming with at Least One Working Transmitter
This procedure applies when you have at least one functional key fob (transmitter). Ensure all transmitters – both working and new ones – are with you during this process. Again, the key blade of the new transmitter needs to be cut before programming.
-
Place the Working Transmitter in the Cupholder: Put the recognized, already programmed transmitter into the vehicle’s cupholder.
-
Use the New Key in the Driver Door Lock: Insert the new, uncut key blade into the lock cylinder located on the outside of the driver’s side door. Turn the key to the unlock position five times within a quick ten-second timeframe. After this step, the Driver Information Center (DIC) in your Buick LaCrosse should display the message “Ready For Remote #2, 3, 4, or 5.” This indicates the system is ready to learn a new transmitter.
-
Place the New Transmitter in the Transmitter Pocket: Locate the transmitter pocket, which is inside the center console storage area, underneath the cupholder. You may need to pull out the cupholder to access this pocket. Place the new transmitter into this pocket.
-
Press the Ignition Button: Press the ignition button in your Buick LaCrosse. Once the transmitter is successfully learned by the system, the DIC display will update to indicate it’s ready for programming the next transmitter if needed.
-
Remove and Test: Take the newly programmed transmitter out of the transmitter pocket and press the unlock button to test if the programming was successful.
To program additional transmitters, repeat steps 3 through 5. Once you have programmed all desired transmitters, press and hold the ignition button for approximately 5 seconds to exit the programming mode.
Scenario 2: Programming When You Don’t Have Any Working Transmitters
If you have lost all your working key fobs for your 2006 Buick LaCrosse with push-button start, you’ll need to follow a slightly longer 30-minute procedure to program new ones. It’s highly recommended to connect your vehicle to a power source, like jumper cables connected to another running vehicle or a battery maintainer, during this process as the car’s battery voltage can drop significantly during the extended programming time. Ensure all new transmitters you wish to program are with you, and the key blades are cut.
-
Use New Key in Driver Door Lock: Insert the new, cut key blade into the driver’s side door lock cylinder and turn it to the unlock position five times within ten seconds. The Driver Information Center (DIC) will display “Remote Learn Pending, Please Wait.”
-
Wait and Press Ignition (First Cycle): Wait for ten minutes. After ten minutes, the DIC display should change to “Press Engine Start Button To Learn.” Once you see this message, press the ignition button. The DIC will revert to displaying “Remote Learn Pending, Please Wait” again.
-
Repeat Wait and Press (Second and Third Cycles): Repeat step 2 two more times. This means you will wait for ten minutes, press the ignition, and wait another ten minutes, press the ignition, for a total of three cycles. After the third cycle, all previously known transmitters will be erased from the system’s memory. The DIC should now display “Ready For Remote #1.”
-
Place New Transmitter in Transmitter Pocket: Access the transmitter pocket in the center console (under the cupholder) and place the new transmitter inside.
-
Press Ignition Button: Press the ignition button. When the transmitter is learned, the DIC display will show that it is ready to program the next transmitter.
-
Remove and Test: Remove the transmitter from the pocket and press the unlock button to verify successful programming.
To program additional transmitters, repeat steps 4 through 6. After programming all desired key fobs, press and hold the ignition button for 5 seconds to exit the programming mode.
Important Note: Your 2006 Buick LaCrosse can have up to five transmitters programmed to it in total.
