I am interest in an key and sensor process to activate a current to move a solenoid, etc. an example might be the "fob" system used for starting a new automobile without a physical key by the use of a proximity device such as the 'fob"

I am not sure if I will have to use a circuit board and chip or something else. In the end it must be very small in size and have a proximity key activation of a few inches to o inches.

Any ideas will be greatly appreciated.
