Is your 2000 Chevy Tahoe Key Fob no longer working, or did you get a replacement that needs programming? Don’t worry, programming your key fob for a 2000 Chevy Tahoe can often be done right at home without a trip to the dealership. This guide provides you with clear, step-by-step instructions to program your 2000 Chevy Tahoe key fob, ensuring you regain convenient keyless entry to your vehicle.
It’s important to note that the 2000 Chevy Tahoe actually uses two different types of key fobs, each requiring a specific programming procedure. Before you begin, identify the FCC ID number on the back of your remote. This will determine which set of instructions you need to follow.
Procedure 1: For Remotes with FCC ID #ABO1502T
This procedure utilizes the OBDII (On-Board Diagnostics II) port in your Chevy Tahoe to enter programming mode.
-
Locate the OBDII Data Link Port: This port is typically found under the driver’s side dashboard. You’ll need to identify pins 8 and 4 within this port.
-
Prepare the Jumper Wire: Carefully inspect the OBDII port to ensure metal contact pins are present in terminals 8 and 4. Using a suitable jumper wire, connect terminal 8 to terminal 4. Keep this jumper wire connected throughout the entire programming process. Note: Ensure you correctly identify terminals 8 and 4 before connecting the jumper wire. Upon successful connection, the vehicle will signal entry into programming mode by automatically locking and unlocking the doors.
-
Program the First Key Fob: On the first key fob you wish to program, press and hold both the LOCK and UNLOCK buttons simultaneously. Continue holding both buttons for approximately 15 seconds. After about 15 seconds, the vehicle will once again lock and unlock the doors to confirm successful programming of this remote. Release the buttons on the key fob.
-
Program Additional Key Fobs: If you have additional key fobs to program (including existing remotes), repeat the previous step (step 3) within one minute of programming the first key fob.
-
Exit Programming Mode: Once you have programmed all desired key fobs, remove the jumper wire from the OBDII port. Programming is now complete. Test each key fob to ensure it is working correctly.
Procedure 2: For Remotes with FCC ID #KOBUT1BT
This procedure utilizes the ignition and door lock button to program your 2000 Chevy Tahoe key fob.
-
Close and Enter the Vehicle: Ensure all doors of your 2000 Chevy Tahoe are fully closed. Enter the driver’s seat.
-
Insert Key into Ignition: Place your key into the ignition switch.
-
Hold Unlock Button: Press and hold the power UNLOCK button located on the driver’s side door panel. Maintain pressure on this button and do not release it until instructed in step 9.
-
Ignition Cycling Sequence (Steps 5-8): Perform the following ignition switch actions in rapid succession:
- Turn the ignition switch to the ON position (turn the key as far as it will go without starting the engine).
- Turn the ignition switch to the OFF position.
- Turn the ignition switch to the ON position again.
- Turn the ignition switch to the OFF position for the final time.
-
Release Unlock Button: Release the power UNLOCK button on the door panel. The vehicle will automatically lock and unlock the doors to indicate it has entered programming mode.
-
Program the First Key Fob: On the key fob you wish to program, press and hold both the LOCK and UNLOCK buttons simultaneously. Continue holding both buttons until the door locks and unlocks. This step may take up to 30 seconds.
-
Program Additional Key Fobs: Immediately repeat step 10 for every additional key fob you need to program, including any previously working remotes. You must program all remotes you want to use during this step.
-
Exit Programming Mode: Turn the ignition switch to the ON position. This action will exit the transmitter programming mode. Test all programmed key fobs to confirm they are functioning correctly with your 2000 Chevy Tahoe.
By following the appropriate procedure based on your key fob’s FCC ID, you can successfully program your 2000 Chevy Tahoe key fob and restore the convenience of keyless entry. If you encounter any difficulties, double-check each step and ensure you are using the correct procedure for your specific remote.
