Lost your keys or is your Ram's key fob acting up? This TOP-VIGOR replacement is here to save the day. It's designed to match the original 4-button remote (FCC ID: GQ4-54T) for Dodge Ram 1500, 2500, and 3500 trucks from 2013 through 2019. IMPORTANT: This is just the shell and electronics with an uncut key blade. You'll need to take it to a locksmith or dealership to get it programmed to your truck and the metal key cut to match your door lock. The battery is already included, which is nice. Once it's set up, it'll work just like the factory remote for locking, unlocking, and maybe the panic button. It's a much cheaper fix than going straight to the dealer. Just make sure your truck is one of the listed years before ordering. Comes in one size: about 2.91 x 1.46 inches. Get back your keyless entry convenience without breaking the bank!
