ceiver will excite the transponder, which is located (but not visible) in the head of the ignition key. The key
transponder 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 . . Some may require additional parts from the vehicle manufacturer. Consult you dealer for the
applications. 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.

These plug into the module. The Status LED plugs into the small two-pin socket, while the Valet® /Program Switch
should be plugged into the larger blue two-pin connector. The Status LED fits into a

The black 3-pin port is provided for personal computer 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 optional PC Interface module, or hand-held programmer, it is pos-
sible to configure any and all of the programmable 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 ) or PC Interface module, they may have been locked. Before proceeding with reprogramming
the learn routines, they must be unlocked with either the 998T or the PC Interface module - this cannot be done
manually with the Valet switch.
