Programming Your 2004 Buick Century Key Fob – Step-by-Step Instructions
Before you begin, ensure you have all the key fobs you wish to program for your 2004 Buick Century. This procedure will erase all previously programmed remotes, so you must program all existing and new remotes in one session.
- Prepare Your Vehicle: Begin by closing all doors of your 2004 Buick Century.
- Ignition Cycle – Part 1: Insert your key into the ignition and turn it to the ON position (do not start the engine). Then, turn the key back to the OFF position and remove it from the ignition.
- Hold Unlock Button: Press and hold the UNLOCK button on the driver’s side door. Do not release the unlock button throughout the next steps.
- Ignition Cycle – Part 2: Insert the key into the ignition and remove it. Repeat this step two more times: insert and remove, insert and remove, and on the third time, leave the key in the ignition in the OFF position. (Key should be inserted a total of three times and left in on the third insertion).
- Release Unlock Button & Enter Programming Mode: Release the UNLOCK button on the door. You should hear three chimes. These chimes indicate that your 2004 Buick Century has entered the key fob programming mode.
- Program Key Fobs: Press and hold both the LOCK and UNLOCK buttons simultaneously on the first key fob you want to program. Continue holding both buttons until the vehicle chimes twice. These two chimes confirm that the key fob has been successfully programmed. Repeat this step for any additional 2004 Buick Century key fobs you need to program.
- Exit Programming Mode: Remove the key from the ignition to exit the programming mode.
Once you have completed these steps, test each of your programmed 2004 Buick Century key fobs to ensure they are working correctly. You should now be able to lock and unlock your doors and utilize other remote functions.
