I had a set of keys stolen with the fob. Fortunately I had another set with a fob.

I ordered another fob. I can't get the truck into programming mode. Dealer could not. Locksmith could not. Locksmith suggested I have an aftermarket add-on.

Dealer wants $85 to diagnose.

I already have the replacement key and it works, but I need the second fob to work so both my wife and I can use the truck.

Suggestions?
