NGS Mach II User Guide v1.1
This section explains how to reprogram compatible keys and modules for Ford, Lincoln and
Mercury vehicles equipped with the passive anti-theft system (PATS).
Because of the large number of combinations of PATS parameters, it is recommended that you refer
to the vehicle’s shop manual in addition to these instructions.
PATS Functions
About PATS Programming
PATS equipped vehicles can be divided into
two types:
PATS I—applies to model years 1996–1998
PATS II—applies to model years 1998– current
NGS Mach II automatically determines which
PATS type is applicable for programming keys
when the model and year of the vehicle is
selected.
Within each system type, vehicles contain
PATS functionality in one of several modules:
• PCM
• VIC
• SCIL
• HEC
• ICM
• PATS
General Guidelines
When programming keys, please keep the
following in mind:
Vehicle Information
—
Refer to the vehicle’s
shop manual for PATS related information.
Spare Keys
—If you need additional spare keys
after completing this procedure, see
Add New
Keys.
Replacing Lost Keys
—If all keys to the
vehicle have been lost, cut new keys
according to the minimum number of keys
needed (see
Keys
in the PATS Programming
Chart) and use the
Erase and Reprogram
Keys
procedure.
Note: If the lost keys are found, they can be
reprogrammed as extra keys.
Maximum Keys
—The module will not accept
a key if the maximum number of keys are
already programmed into the vehicle (see
PATS Programming Chart). You can check the
NUMKEY PID to see if the maximum number
of keys have been programmed.
Theft Indicator
—Attempting to start the
vehicle with an unprogrammed key can
trigger the anti-scan feature, causing the
theft indicator to flash rapidly. If this occurs:
1. Leave the key in
RUN
for 30 seconds to
complete the anti-scan cycle.
2. Return to the beginning of the interrupted
procedure.
