How to Program a 2001 Buick Century Key Fob

Is your 2001 Buick Century Key Fob no longer working, or did you recently replace it? Luckily, programming a new or existing key fob for your 2001 Buick Century is a straightforward process you can do yourself, without a trip to the dealership. This guide provides simple, step-by-step instructions to get your 2001 Buick Century key fob programmed and working again in no time.

Step-by-Step Programming Guide

Before you begin, make sure you have all the key fobs you intend to use with your vehicle. Programming your 2001 Buick Century will erase all previously programmed remotes, so you’ll need to reprogram all of them during this session.

1. Ensure all vehicle doors are closed completely.
2. Insert your key into the ignition. Turn the ignition to the ON position, which is as far as you can turn the key without starting the engine.
3. Turn the ignition back to the OFF position and remove the key from the ignition.
4. Press and hold the power door lock switch on the driver’s side door in the UNLOCK position. Keep holding it throughout the next steps.
5. Insert the ignition key into the ignition lock cylinder and then remove it immediately. Do not turn the key at any point during this step.
6. Repeat step 5 two more times. Insert the ignition key into the ignition lock cylinder and remove it. Again, do not turn the key.
7. Insert the ignition key into the ignition lock cylinder one last time and leave it in the ignition. Do not turn the key.
8. Release the door lock switch. You should hear three audible beeps from your Buick Century. These beeps indicate that the vehicle has successfully entered the key fob programming mode.
9. Now, take the key fob you want to program. Press and hold both the LOCK and UNLOCK buttons on the key fob simultaneously for about 15 seconds. After approximately 15 seconds, the vehicle should beep twice. These two beeps confirm that the key fob has been successfully programmed.
10. If you have additional key fobs to program, repeat step 9 for each of them. You can program up to four key fobs in total, including any previously working ones.
11. Once you have programmed all your desired key fobs, remove the ignition key from the ignition to exit the programming mode.

Your 2001 Buick Century key fob should now be programmed and ready to use. If you experience any difficulties or prefer professional assistance, you can search online for local key fob programming services in your area.
