Lost your key fob or need to program a new one for your 1999 Chevrolet Silverado? Don’t worry, programming your key fob at home is a straightforward process that can save you time and money compared to dealership programming. This guide provides comprehensive, easy-to-follow instructions for programming your 1999 Silverado key fob, covering both the New Body Style and Classic Body Style models.
Programming Your 1999 Silverado Key Fob – New Body Style
This procedure applies to the “New Body Style” of the 1999 Chevrolet Silverado. Follow these steps carefully to successfully program your key fob:
-
Ensure All Doors Are Closed: Begin by making sure all doors of your 1999 Silverado are completely closed. This is crucial for the programming sequence to initiate correctly.
-
Insert Key into Ignition: Place your ignition key into the ignition cylinder. Do not turn the key yet.
-
Press and Hold the UNLOCK Button: Locate the power UNLOCK button on the driver’s side door panel. Press and hold this button down. Maintain pressure on the button until instructed to release it in a later step.
-
Ignition Cycling Sequence (Steps 5-8): Perform the following steps in rapid succession. This timing is important for entering programming mode.
-
Turn Ignition to ON: Turn the ignition key to the “ON” position. This is the position just before starting the engine. The dashboard lights should illuminate.
-
Turn Ignition to OFF: Turn the ignition key back to the “OFF” position.
-
Turn Ignition to ON (Again): Repeat step 5, turning the ignition key to the “ON” position once more.
-
Turn Ignition to OFF (Again): Repeat step 6, turning the ignition key back to the “OFF” position again.
-
Release the UNLOCK Button: Now, release the power UNLOCK button on the door panel that you have been holding since step 3.
-
Observe Door Locks: Upon releasing the UNLOCK button, the vehicle should automatically respond by cycling the door locks – they will lock and then unlock. This lock cycling indicates that your 1999 Silverado has successfully entered key fob programming mode. If the door locks do not cycle, you will need to repeat the procedure from step 1. Ensure you release the unlock button after the locks cycle, not before. If unsuccessful, remove the key, open the driver’s door and restart from step 1.
-
Program the First Remote: Take the key fob you wish to program. Press and hold both the LOCK and UNLOCK buttons on the remote simultaneously. Continue holding both buttons until the doors lock and then unlock again. This may take up to 30 seconds. This step programs the first key fob to your Silverado.
-
Program Additional Remotes: If you have additional key fobs to program (including any existing, working remotes you want to continue using), repeat step 11 immediately for each additional remote. It is important to program all remotes you want to use in this session, as programming a new remote may erase previously programmed ones if not done together.
-
Exit Programming Mode: Turn the ignition key to the “ON” position. This action will exit the key fob programming mode.
-
Test 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 and verifying the doors respond.
Programming Your 1999 Silverado Key Fob – Classic Body Style
This procedure is for the “Classic Body Style” 1999 Chevrolet Silverado. This method involves using the OBDII Data Link Port.
- Locate the Data Link Port (OBDII Port): The Data Link Port, also known as the OBDII port, is located under the dashboard on the driver’s side of your Silverado. You’ll need to identify pins 8 and 4 on this port. Note that the port is wider on the top row, which can help with orientation.
Identifying the OBDII Port for 1999 Silverado Classic Body Style Key Fob Programming
-
Prepare Jumper Wire and Connect Pins 8 and 4: Ensure that terminals 8 and 4 of the OBDII port have metal contact pins. Using a suitable jumper wire, connect terminal 8 to terminal 4. Keep the jumper wire connected throughout the entire programming procedure. It’s crucial to correctly identify terminals 8 and 4.
-
Enter Programming Mode (Door Lock Confirmation): Once you connect pins 8 and 4 with the jumper wire, your Silverado should respond by automatically locking and unlocking the doors. This door lock cycle confirms that the vehicle has entered the key fob programming mode for the Classic Body Style.
-
Program the First Transmitter (Key Fob): Take the first key fob you want to program. Press and hold both the LOCK and UNLOCK buttons on the key fob simultaneously. After approximately 15 seconds, the vehicle will respond again by locking and unlocking the doors. Release the buttons on the transmitter after this confirmation.
-
Program Remaining Transmitters: Within one minute of completing step 4, repeat the same process (step 4) for any remaining key fobs you need to program.
-
Remove Jumper Wire: After programming all desired key fobs, remove the jumper wire from the OBDII port, disconnecting pins 8 and 4.
Now you have successfully programmed your 1999 Chevrolet Silverado key fob. Test each remote to ensure proper function of the lock and unlock buttons.
