Hide a chip key somewhere inside the car to drive. Then the ordinary key can fit your EDC easier. Make SURE the ordinary key unlocks the door BEFORE you leave the dealership or where ever you got the key cut.


Keep in mind that hiding the chip key too near where it needs to be read can disable the antitheft system when you don't intend to. What's "too near"? I don't know. Probably best to experiment carefully with your car.

Also, I've heard that some insurance companies will deny auto theft claims if you can't produce all the keys on demand.
