 Remote Car Keys of Summoning, Lesser
Remote Car Keys of Summoning resemble mundane remote car keys, including lock and unlock keys. There is an additional key, however, than summons a specific car when pressed. Each set of keys is attached to a a specific vehicle (such as a red Toyota 4-Runner or a souped-up Ducati). When the key is pressed the vehicle appears and remains for up to an hour per day. When the duration ends or the car is reduced to disabled status, the car disappears. It can be summoned again the following day.
