Is your 2007 Silverado Classic giving you trouble with its key fob, or did you perhaps lose your remote? You might be surprised to learn that adding or reprogramming a key fob for your truck is often simpler than you think. Many Silverado Classic models from this era came equipped with remote keyless entry, even if it’s not immediately obvious. Let’s explore how to determine if your truck has this feature and how to get your key fob working, saving you a trip to the dealership if possible.
Does Your 2007 Silverado Classic Already Have Keyless Entry?
Before assuming your truck lacks keyless entry, there’s a quick way to check. Many 2007 Silverado Classic trucks with power windows and locks were factory-equipped with remote keyless entry. The easiest way to verify this is by checking the Service Parts Identification label, often referred to as the RPO sticker. This sticker is usually located in your glovebox.
Look for the following RPO codes on the sticker:
- AU0: This code indicates standard doors, which is a general code and less indicative of keyless entry itself.
- A31: This code signifies power windows.
- AU3: This is the key code! AU3 specifically denotes power door locks, and crucially, if you have both A31 and AU3, it strongly suggests your Silverado Classic is equipped with remote keyless entry.
If you find all three codes – AU0, A31, and AU3 – your truck likely already has the remote keyless entry system installed. This means you might just need to purchase a new key fob and program it to your vehicle, rather than needing to install a whole new system.
Programming Your 2007 Silverado Classic Key Fob – Step-by-Step
Assuming your Silverado Classic is equipped with keyless entry, programming a new key fob is a straightforward process you can do yourself. Here’s how:
- Ensure all doors are fully closed. This is crucial for the programming sequence to initiate correctly.
- Insert your ignition key into the ignition lock cylinder.
- Press and hold the door UNLOCK switch on your driver’s side door panel. Keep holding it down throughout the next steps.
- Cycle the ignition key between the ON and OFF positions twice. This means turning the key to the “ON” position (without starting the engine) and then back to “OFF”, and repeating this once more, for a total of two cycles (ON, OFF, ON, OFF).
- Release the door UNLOCK switch. Once you release the switch, the doors should automatically lock and then unlock. This lock/unlock cycle confirms that your truck has entered the key fob programming mode.
- Program the first key fob: Press and hold both the LOCK and UNLOCK buttons simultaneously on the key fob you want to program. Continue holding both buttons for approximately 15 seconds. After the short delay, the doors will lock and unlock again, confirming that the first key fob has been successfully programmed.
- Program additional key fobs (if needed): If you have more key fobs to program (up to a maximum of four), repeat step 6 for each additional key fob.
- Exit programming mode: Turn the ignition switch to the “RUN” position (or simply start your engine). This action will exit the keyless entry transmitter programming mode.
- Test your key fobs: Operate all the buttons on each programmed key fob to verify they are working correctly, locking and unlocking the doors as expected.
What If Programming Doesn’t Work?
If you’ve followed the programming procedure carefully and your key fob still isn’t working, there are a couple of possibilities:
- Incorrect Key Fob: Ensure you have purchased the correct key fob model for a 2003-2007 Silverado pickup. Using the wrong type of fob will prevent successful programming.
- BCM Reprogramming Needed: In some cases, even if your truck has the RPO codes indicating keyless entry, the Body Control Module (BCM) might require a reflash or reprogramming by a dealer to fully activate the keyless entry feature. This is less common, but possible.
If you suspect the BCM needs reprogramming, your next step would be to contact your local Chevrolet dealership. Explain that you are trying to program a key fob for your 2007 Silverado Classic and suspect the BCM might need to be reflashed to enable the keyless entry function. While there may be a labor charge associated with this service, it should resolve the issue and get your remote keyless entry system working. Sometimes, if you are lucky and have a helpful service department, they might perform the reflash at a minimal cost or even for free.
By following these steps, you should be able to quickly determine if your 2007 Silverado Classic is ready for a key fob and get it programmed and working efficiently. Enjoy the convenience of remote keyless entry!
