Inexpensive way to get an extra key?

[Top_Fuel]

To add a key, you must already have 2 registered keys...

Interesting. That's the way you do it for Ford keys. Here's a simple tip for you guys with actual keys...

Never have fewer than 3 keys programmed to your car.

That way if you lose one, you can always get a new key cut and register it to the car yourself. If you only have 2 keys and lose one, you are heading to the dealer (or a locksmith with a good aftermarket scan tool).
