I lost a key fob. Is it true if I activate 3 the one I lost will deactivate? I’m buying two from Amazon and the dealership will active them and reactivate the one I still have , an original
It all depends what steps they take to program the new fobs.
You can have a total of 8 fobs programmed to the truck.
If you hand them two brand new fobs, and just tell them to program them to your truck, that’s exactly what they’ll do, and you’ll have a total of 4 programmed fobs for the truck. The lost fob will still work if it’s found.
Now, if you have a lost/stolen fob, and you don’t want it to work on your truck anymore if it’s found, AND you want to have two new fobs programmed to the truck, they have to perform extra programming steps.
First they need to perform the “erase all fobs” procedure. This will clear all programmed fobs from the truck so none of them will work anymore.
Then they’ll take the original fob that you do have and program it back to the truck, followed by programming the two additional new fobs- leaving you with a total of three fobs programmed to the truck.
You can do all of this by yourself using JScan, BTW.
