Abstract
An improved key fob and key combination allows the mechanical key to be removed from the key fob and given to a valet attendant. The key is provided with a mechanical latch which may be easily removed from the key fob. When the key is removed, secured areas on the vehicle are locked. Moreover, the vehicle has limited operation when the mechanical key is not received with the key fob. In a second feature of this invention, a locator function on the key fob provides an indication of an approximate direction to a vehicle in a parking area. The key fob relies upon RF transmissions from the vehicle to determine an approximate direction to the vehicle.
