Experiencing issues with your 07 Tahoe Key Fob, specifically the remote start? You’re not alone. Many 2007 Chevy Tahoe owners encounter a peculiar problem where pressing the remote start button doesn’t ignite the engine but instead pops open the rear liftgate glass. This can be confusing and frustrating, especially when you’re expecting a warm car on a cold morning.
One common cause of this issue is simply using the wrong key fob. For a 2007 Tahoe equipped with remote start, the key fob should have six buttons, including a dedicated remote start button with a curved arrow icon. It’s possible the dealership provided a key fob intended for a different vehicle or trim level. Look closely at your key fob; does it match this description?

Another potential issue is the remote start programming itself. Even with the correct key fob, the system might not be properly activated or configured in your Tahoe’s computer. To correctly use remote start on a 2007 Tahoe, you typically need to press the lock button twice, then press and hold the remote start button. Have you tried this specific sequence? If you have and the rear glass still pops open, a programming error is likely.
To confirm if your 2007 Tahoe is even equipped with the remote start option from the factory, you can check the glove box for the service option code “AP8”. While the original poster in the forum mentioned lacking this code and only having “AP3”, it’s still worth double-checking your vehicle’s service sticker.
If you’ve confirmed you have the correct key fob, tried the proper starting sequence, and suspect a programming issue, the best course of action is to return to the GM dealer. Since you mentioned they were supposed to set up the remote start, this issue should be covered, especially if the vehicle was purchased with a Certified Pre-Owned warranty. They can diagnose the system and ensure your 07 Tahoe key fob correctly activates the remote start function, not just the rear glass.
