Abstract
An add-on, or after-market, remote-control vehicle security system expander allows auxiliary remote-control functions to be added to previously-installed remote-control systems. Using complementary remote control functions for multiple actuation encoding permits auxiliary function codes to be transmitted without a change of state in the underlying function. Signal validation by coincidence timing and voltage comparison are used to prevent inadvertent local actuation of the auxiliary remote-control functions. Decoding is also limited to a time-window to reduce electrical interference.
