Methods and apparatus are provided for handling the response sequence with geometric elimination of a plurality of keyless fobs. The remote fobs are interrogated with a body control module. A first signal is issued from a first set of remote fobs in a first time slot in response to the interrogation signal from the body control module. A second signal is issued from a second set of remote fobs in a second time slot in response to the interrogation signal from the body control module. The second time slot differs from the first time slot. A first remote fob is authenticated when the first signal is received by the body control module in a free and clear state. The second remote fob is authenticated when the second signal is received by the body control module in the free and clear state. If neither the first nor second signals are received in the free and clear state, the remote fobs are re-interrogated by the body control module.

Methods and apparatus are provided for rendering electronic keys left behind in a vehicle temporarily inactive. The apparatus comprises a vehicle security control module in wireless communication with the electronic keys, and having operatively coupled together a receiver, a processor, non-volatile memory and a short-range transmitter. When the module receives a valid lock command from any source it sends a short-range interrogation signal to keys within the vehicle. Left-behind keys respond and send their unique ID(s) to the module's receiver. The processor obtains the unique ID(s) from the receiver and sets one or more inhibit flags in memory or equivalent to identify those keys as left-behind keys. The processor thereafter ignores commands from such left-behind keys, thereby rendering them temporarily inoperative until a valid unlock command is received form another source, whereupon the processor clears the inhibit flags from memory and restores the left-behind keys to active status.
