Lost your key fob or need to program a new one for your 2000 Chevy Tahoe? Don’t worry, programming your key fob can often be done yourself, saving you a trip to the dealership. This guide provides 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 may use one of two different types of key fobs, each requiring a specific programming procedure. Determine your key fob’s FCC ID to ensure you follow the correct steps.
Identifying Your Key Fob Type
Before you begin, locate the FCC ID on the back of your key fob. You’ll need to identify whether your remote has FCC ID #ABO1502T or FCC ID #KOBUT1BT. This identification is crucial because the programming procedures differ for each type. Once you’ve identified your FCC ID, proceed with the corresponding programming instructions below.
Programming Key Fobs with FCC ID #ABO1502T
This procedure utilizes the Data Link Port (DLP), also known as the OBDII port, typically found under the driver’s side dashboard.
-
Locate the OBDII Port: Get down to the driver’s side footwell and look under the dashboard. You’re searching for the Data Link Port, which is a trapezoidal connector.
-
Prepare the Jumper Wire: Inspect your OBDII port to ensure metal contact pins are present in terminals 8 and 4. You will need a jumper wire to connect terminal 8 to terminal 4.
-
Enter Programming Mode: Connect the jumper wire between terminals 8 and 4 of the OBDII port and leave it connected throughout the programming process. Upon successful connection, the vehicle will automatically lock and unlock the doors. This indicates that your 2000 Chevy Tahoe has entered programming mode.
-
Program the First Key Fob: Take 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 again respond by locking and unlocking the doors. Release the buttons on the key fob.
-
Program Additional Key Fobs: Within one minute of completing step 4, repeat the process for any remaining key fobs you need to program. For each additional key fob, press and hold the LOCK and UNLOCK buttons together for 15 seconds until the doors lock and unlock.
-
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 successfully locks and unlocks the doors.

This programming method utilizes the ignition and door lock button.
-
Prepare the Vehicle: Ensure all doors of your 2000 Chevy Tahoe are fully closed before beginning the programming sequence.
-
Insert and Hold: Insert your ignition key into the ignition cylinder. Press and hold down the power UNLOCK button located on the driver’s side door panel. Maintain pressure on the UNLOCK button throughout the subsequent steps until instructed to release it.
-
Ignition Cycling (Rapid Sequence): Perform steps 4 through 8 in quick succession.
- Turn the ignition switch to the ON position (just before starting the engine).
- Turn the ignition switch back to the OFF position.
- Turn the ignition switch to the ON position again.
- Turn the ignition switch back to the OFF position.
-
Release Unlock Button: Release the power UNLOCK button on the door panel. The vehicle will automatically lock and unlock the doors, signaling that it has entered programming mode.
-
Program Key Fobs: Immediately proceed to program your key fobs. On the first key fob, press and hold both the LOCK and UNLOCK buttons simultaneously. Continue holding them until the doors lock and unlock. This step may take up to 30 seconds.
-
Program Remaining Key Fobs: Immediately repeat step 10 (pressing and holding LOCK and UNLOCK buttons) for every additional key fob you wish to program, including any previously working key fobs. It’s important to reprogram all fobs at once.
-
Exit Programming Mode: To finalize the programming and exit programming mode, turn the ignition switch to the ON position.
-
Test Key Fobs: Test each programmed key fob to confirm it correctly operates the door locks and other keyless entry functions of your 2000 Chevy Tahoe.
By following the correct procedure for your specific 2000 Chevy Tahoe key fob, you can easily program it yourself and regain the convenience of keyless entry. If you encounter any difficulties, double-check your FCC ID and carefully re-read each step to ensure accuracy.
