This is pretty great. Resetting your car’s keychain fob is something that has to happen from time to time — when a fob’s battery runs out, for instance, or you pick up an extra one. The process of pairing it is one of these rituals that I have always loved, like the special way you had to blow on your NES cartridges to get them to play.
The process is different on all the different makes, of course, but if you’ve got Ford, GM, Nissan, Toyota, or Jeep, there’s a good chance the instructions are here.
