Is your 2002 Buick Century Key Fob no longer working, or have you purchased a replacement remote? Gaining keyless entry to your Buick Century is simple and can be done right in your driveway. Forget expensive dealership programming – this guide provides straightforward steps to program your 2002 Buick Century key fob yourself.
Step-by-Step Guide to Program Your 2002 Buick Century Key Fob
Before you begin, ensure you have all key fobs you intend to use with your vehicle. Programming will erase all previous remote codes, so you’ll need to reprogram all remotes at once.
-
Vehicle Preparation: Begin by closing all doors on your 2002 Buick Century. This ensures the system is properly set for programming mode.
-
Ignition Cycle Start: Insert your key into the ignition. Turn the ignition to the “ON” position – this is the position just before you would crank the engine to start.
-
Turn Ignition Off: Turn the ignition back to the “OFF” position and remove the key completely from the ignition.
-
Engage Door Lock Switch: Locate the driver’s side door lock switch. Press and hold the switch in the “UNLOCK” position. Maintain pressure on the unlock switch throughout the next steps.
-
Key Insertion Sequence – Step 1: Insert the ignition key into the ignition cylinder and then immediately remove it. Do not turn the key at any point during this step.
-
Key Insertion Sequence – Step 2: Repeat step 5. Insert the ignition key into the ignition cylinder and then immediately remove it again, without turning it.
-
Key Insertion Sequence – Step 3: Insert the ignition key into the ignition cylinder for a third time. This time, leave the key in the ignition cylinder. Do not turn the key.
-
Release Door Lock Switch: Release the driver’s side door lock switch that you have been holding in the “UNLOCK” position.
-
Program Mode Confirmation: Listen for the vehicle to sound three beeps. These beeps indicate that your 2002 Buick Century has successfully entered programming mode and is ready to learn the new key fob codes.
-
Key Fob Programming: Take your first key fob remote. Simultaneously press and hold both the “LOCK” and “UNLOCK” buttons on the remote. Continue holding both buttons until the vehicle beeps twice. These two beeps confirm that the key fob has been successfully programmed. This step may take approximately 15 seconds.
-
Program Additional Key Fobs (Optional): If you have additional key fobs to program, repeat step 10 for each additional remote. You can program up to four key fobs, including any existing remotes you had previously.
-
Exit Programming Mode: Remove the ignition key from the ignition cylinder. This action will automatically exit the programming mode.
You have now completed the programming process for your 2002 Buick Century key fob. Test each of your programmed remotes to ensure they are working correctly by locking and unlocking your doors remotely.
