Passive Transponder Systems:
Passive transponder systems have become the
most popular anti-theft system among vehicle
manufacturers (Ford, Honda, BMW, Toyota,
Nissan and others). This system requires use of
a tiny passive transmitter housed in the base of
the key. This device activates when placed close
to the vehicle’s ignition switch. The starter will
usually crank but the fuel system will be
disabled, not allowing the vehicle to run, if the
transponder is not detected. To properly
interface into transponder systems, a
transponder bypass module must be
installed. These modules allow full
functionality of the factory anti-theft system
and usually require the use of a spare key.
ADDING TRANSMITTERS
To add a new transmitter to the system have
the desired transmitters ready and follow the
Code Learning sequence.
To enter Code Learning Mode:
1. Turn the ignition on, off, on, off and leave on.
• The siren will chirp.
2. Press and hold the Override switch.
• The siren will chirp 3 times.
3. Release the Override switch.
4. Press the Lock Button on the transmitter.
• The siren will chirp once.
5. Repeat step 3 for each additional
transmitter, up to four total transmitters.
• The siren will chirp an additional time for
each added transmitter.
6. Turn off the ignition.
• The siren will chirp 3 times.
NOTE: If a transmitter is lost or stolen, make sure
to code all 4 transmitter memory locations.
(Example: If only one transmitter is used, repeat
step 3 three more times to remove any
previously programmed transmitters.)
