A vehicle ignition system includes a fob for transmitting an identification code. The fob includes a low frequency transceiver circuit and low frequency antenna. An ignition module is provided including, a housing, switch contacts and a push button slidably mounted in the housing and arranged so that pushing of said button closes said switch contacts. A LF coil is provided and is axially stationary within the housing and is located inside of the push button. An ignition module circuit provides power to the fob and establishes low frequency communications with the fob via the LF coil. An immobilizer circuit is operatively coupled to the ignition module for permitting or preventing actuation of the ignition system in response to the low frequency communications with the fob and the ignition module.
