Waiting to see if this will work on my Classic 2500 Crew Cab GMC as well.

Was about to give up on my Classic 2500 Crew Cab GMC, but this gives me hope.

My Classic 2500 Crew Cab GMC's been in the garage for a week over this. Thanks!

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

Cost & Options

Key Programming

Key Tip: Newer cars often require dealer programming for first key replacement
Key Programming
Common reasons: wrong key type for your vehicle, anti-theft system needs reset, low car battery voltage during programming, or the key isn't properly synced. Some cars also have programming limits (only 2-4 keys can be registered).
