Programming Your 1999 Chevy Silverado Key Fob (New Body Style)

This procedure applies to the “New Body Style” of the 1999 Chevy Silverado. If you are unsure which body style you have, consult your vehicle’s documentation or compare it to online resources.

1. Ensure All Doors Are Closed: Begin by making sure all doors of your 1999 Chevy Silverado are completely closed.

2. Insert Key into Ignition: Place your key into the ignition cylinder, but do not turn it on yet.

3. Hold Power UNLOCK Button: Locate the power UNLOCK button on the driver’s side door panel. Press and hold this button down. Keep holding it until step 9 instructs you to release it.

4. Rapid Ignition Sequence (Steps 5-8): Perform the following steps in quick succession:

   5. Turn Ignition to ON: Turn the ignition key to the “ON” position. This is the position just before starting the engine – where the dashboard lights illuminate.

   6. Turn Ignition to OFF: Turn the ignition key back to the “OFF” position.

   7. Turn Ignition to ON (Again): Turn the ignition key to the “ON” position once more.

   8. Turn Ignition to OFF (Again): Turn the ignition key back to the “OFF” position again.

5. Release Power UNLOCK Button: Now, release the power UNLOCK button that you have been holding down since step 3.

6. Observe Door Locks: At this point, your 1999 Chevy Silverado should automatically cycle the door locks – they will lock and then unlock. This indicates that the vehicle has successfully entered key fob programming mode. If the locks do not cycle, you need to start the procedure over from step 1. Make sure you release the unlock button after the locks cycle, not before.

7. Program Key Fob(s): Take your first key fob remote. Press and hold both the LOCK and UNLOCK buttons simultaneously on the remote. Continue holding them until the doors lock and unlock again. This might take up to 30 seconds.

8. Program Additional Remotes (If Any): If you have additional key fobs to program (including any existing remotes you want to continue using), repeat step 10 immediately for each additional remote.

9. Exit Programming Mode: Turn the ignition key to the “ON” position one last time. This will exit the key fob programming mode.

10. Test Your Remotes: Remove the key from the ignition and test all programmed key fobs to ensure they are working correctly by pressing the lock and unlock buttons.

Programming Your 1999 Chevy Silverado Key Fob (Classic Body Style)

This procedure is for the “Classic Body Style” 1999 Chevy Silverado. This method involves using the OBDII Data Link Port.

1. Locate the Data Link Port: Find the Data Link Port. It’s located under the dashboard on the driver’s side. It’s important to identify pins 8 and 4 on this port. Note that the port is wider on the top row to help with orientation.

2. Prepare Jumper Wire and Connect Pins 8 and 4: Ensure that terminals 8 and 4 of the Data Link Port have metal contact pins. Use a suitable jumper wire to connect terminal 8 to terminal 4. Leave the jumper wire connected throughout the entire programming process. Double-check you have correctly identified terminals 8 and 4. Upon connecting the pins, the vehicle should respond by automatically locking and unlocking the doors, signaling entry into programming mode.

3. Program First Key Fob: Take the first key fob you want to program. Press and hold both the LOCK and UNLOCK buttons on the transmitter simultaneously. After approximately 15 seconds, the vehicle will respond again by locking and unlocking the doors. Release the buttons on the transmitter.

4. Program Remaining Key Fobs: Within one minute, repeat the previous step (step 3) for any remaining key fobs you need to program.

5. Remove Jumper Wire: Once you have programmed all desired key fobs, remove the jumper wire from the OBDII Data Link Port.

By following the appropriate set of instructions for your 1999 Chevy Silverado’s body style, you can easily program your key fobs and regain the convenience of remote locking and unlocking. Always test each key fob after programming to ensure successful operation.
