Abstract
A remote function fob is disclosed for a passive entry-passive start (PEPS) system for a vehicle. The fob may include a battery, a low frequency (LF) receiver, and a controller. The controller may be configured to enable a low current consumption mode wherein the LF receiver is disabled such that the fob is unable to respond to a PEPS request signal transmitted from a vehicle control module. A method is also disclosed which may include enabling a low current consumption mode wherein a fob receiver is disabled such that the fob is unable to respond to a PEPS request signal transmitted from a vehicle control module. In such a fashion, a shelf-life of the fob battery may be extended.
