Regarding car keys and assuming at least one of the doors has a mechanical lock cylinder (only the driver's door on my car has one; most cars these days rely on the electronic key fob to unlock/lock) you can have an ordinary key cut to unlock the door to gain entry. 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.
