Oh, heck, the stupid security key fob with my 1996 Nissan Quest/Mercury Villager sometimes goes dopey, and won’t let us start the car.
A fresh fob would probably cost $100. I prefer having $3 keys for my duplicates. All these things take control from the driver/owner and put them into the computer.
The fob for my current car is being held together with Gorilla tape. The local Ace Hardware claims that they can duplicate programmable keys for a fraction of what the dealership will want- I better see if they can dupe mine before the tape gives up.
