Key programming

[FirNaTine]

Hi all new member here. I recently bought a 2016 2500 HD. When I use the keys they are programmed as keys number 2 and 3. Key number 1 is nowhere to be found. My question is there anyway to reprogram them as #1 #2 so the memory features line up with the keys?

Hello,

In GDS2 all can be erased and relearned. The dealer or someone with access can reprogram your truck.
