If you need a new key for your 2017 Chevy Tahoe, you might think a trip to the dealership or a locksmith is inevitable. While a professional scan tool is typically required for key programming, there’s a potential workaround that could save you time and money. This guide outlines the process a forum user shared for programming a new key fob using a Snap-on scan tool, offering a DIY solution for those with access to such equipment.
DIY Key Programming with a Snap-on Scan Tool
One Tahoe owner successfully programmed a new key and remote for about $15 using an aftermarket key, a locksmith for cutting, and a Snap-on scan tool. If you have access to a similar professional-grade diagnostic tool, you might be able to replicate this process. Here’s a breakdown of the steps they followed:
1. Vehicle Identification and System Selection:
- Power on the Snap-on scan tool.
- Choose the “Scanner” function.
- Accurately identify your vehicle by entering the Year, Make, Model, and VIN.
- Select the “Keyless Entry” system.
2. Module Setup and Key Programming:
- Navigate to “Module Setup.”
- Choose the “Program Key Fobs” option.
- Carefully review the on-screen instructions before proceeding.
- Click “Continue.”
3. Key Programming Options:
- The system will offer various programming options, such as erasing all existing keys and programming new ones or programming a key to an empty slot. The user in this case opted for the “next open slot.”
4. Programming the New Key:
- Scroll through the available key slots until you find an empty one.
- Select the empty slot. (The example used slot #3.)
- Press “Y” to confirm the programming selection at the top of the screen.
- Press “Y” again to initiate programming.
- Press and hold both the “LOCK” and “UNLOCK” buttons on the new key fob simultaneously.
- Continue holding the buttons until the screen displays “YES” at the end of the chosen slot, indicating successful programming.
5. Completion and Testing:
- Exit the programming menu on the scan tool.
- Test the newly programmed key fob by attempting to lock and unlock your Tahoe’s doors and starting the engine.
Important Considerations
This method relies on having access to a specific professional-grade scan tool. While potentially cost-effective, it might not be a feasible option for everyone.
Alternatives: If you lack access to a suitable scan tool, consulting a qualified locksmith or dealership remains the most reliable way to program a new key for your 2017 Chevy Tahoe. They possess the necessary expertise and equipment to ensure proper key programming and functionality.
Remember that key programming procedures can vary, so always consult your vehicle’s owner’s manual for model-specific instructions.
