I keep a door key in the outside kitchen. If that happens to be locked I also have a magnetic "hide a key" with a key for the doors and storage compartments stuck inside between the spare tire and tire mount, where it is at the "hide a key" can not be seen but yet is very secure and fairly easy to get to if need be.
