will excite the transponder, which is located (but not visible) in the head of the ignition key. The key transpon-
der will then send a unique code back to the transceiver for evaluation. If the code matches a valid code of the
system, the vehicle will be allowed to start. Most of these transponder-based systems can be bypassed using p p / / n n
5 5 5 5 5 5 U U (or 5 5 5 5 6 6 U U ). Some may require additional parts from the vehicle manufacturer. Consult you dealer for the appli-
cations. For most Ford PATS transponders, p p / / n n 5 5 5 5 5 5 F F can be used, except for the following vehicles, which will
require p p / / n n 5 5 5 5 5 5 U U : '97 and newer Mark VII, and 2000 and newer Taurus/Sable, Contour/Mystique and Focus.

The black 3-pin port is provided for programming of the unit. The unit can also be programmed using the
Bitwriter (p p / / n n 9 9 9 9 8 8 T T ). When using the hand-held programmer, it is possible to configure any and all of the pro-
grammable functions as well as lock the Transmitter/Receiver and System Features Learn Routines so that
unauthorized users cannot change the configuration or program transmitters to the unit.
When the learn routines have previously been programmed using an optional hand-held system programmer
(p p / / n n 9 9 9 9 8 8 T T ), they may have been locked. Before proceeding with reprogramming the learn routines, they
must be unlocked with the 998T - this cannot be done manually with the Valet switch.
