I’ve got a 2012 2017 GMC Sierra 3500HD Base, would this method still work?

My 2017 GMC Sierra 3500HD Base's immobilizer is stuck. Hoping this helps.

Was about to give up on my 2017 GMC Sierra 3500HD Base, but this gives me hope.

Does this method work for the 2017 GMC Sierra 3500HD Base models from 2010 onward?

🔑 Car Key & Fob FAQ

Common questions about key programming, fob issues, and replacement options

Key Programming
Some vehicles allow DIY key programming using specific sequences (like turning ignition on/off with original keys). However, most modern cars require specialized equipment only locksmiths or dealers have. Check your owner's manual for your specific model.
Key Programming
Most transponder keys and smart keys can be reprogrammed if they haven't been damaged. Basic mechanical-only keys (no chip) can't be reprogrammed - they must be physically cut to match your locks.
Cost & Options
Locksmiths are typically 30-50% cheaper than dealerships for key replacement and programming. However, some newer models (especially luxury brands) may require dealer-only programming tools. Always get quotes from both.

Key Tip: Keep spare keys in a faraday bag to prevent signal amplification theft
Key Programming
Programming syncs the key's transponder chip with your car's immobilizer system. The process varies by manufacturer but generally involves: 1) authenticating with the car's computer 2) erasing old keys if needed 3) programming new key codes 4) testing functionality.
Key Fact: The average driver will lose 1-2 car keys during ownership
