Bypassing Transponder/PassKey 3 / P.A.T.S./"Smart Key" Anti-
Theft Systems
Note: For this type of security system - you must sacrifice one of the spare keys
that comes with the car. This key will be used for the transponder. The dealer-
ship can progam a spare key, but make sure they program all keys to the vehicle
at the same time since learning just one transponder could erase all other key
transponders (including the key used for the remote starter).
A.
Remove the transponder from the key (the key may have a door on the top
of the key that can be opened and the transponder can be removed).
Alternatively, the entire key may be mounted inside the receiver case.
Be sure to cut the metal teeth of key in half or grind off some of the teeth
to render the key unusable if your vehicle is stolen.
B.
Pull apart the receiver case and place the transponder, or the head of the
key, on top of the circuit board. Transponders are directional and must be
placed along the same direction that the key would lay.
Use the cable ties and double stick foam tape provided. Place one layer of
tape on the circuit board and then the transponder or key, and the second
double-stick foam tape on top of it. Use the cable ties to hold the key
securely in place.
C.
The transponder LOOP goes underneath the steering column and up
toward the ignition key cylinder and needs to be positioned so that there
are 3 to 4 full turns around the ignition key cylinder as shown below. The
length of the transponder loop can be increased if necessary. Transpon-
der systems often have a black plastic ring around the ignition lock
switch. This is the vehicle’s transponder pick-up antenna. It is important
that the 3 to 4 loops be mounted on or as close to this black plastic ring
as possible. Slide the tube up toward the ignition switch to tighten the
loops of wire. Use electrical tape to hold the loops in place. Plug the other
end of the transponder loop into the transponder jack on the remote car
starter module.
D.
Now start the vehicle with the remote starter. If the vehicle starts and runs
for at least 30 seconds the transponder bypass is correct. Note: If the
vehicle does not start with the remote starter, try adjusting or changing
the position of the transponder on the circuit board or adjusting the
position of the two loop wire around the transponder pick-up antenna
mentioned above.
Transponder Loop Installation Tips:
Getting the loops around the vehicle's transponder pick-up antenna is the
MOST important part of this bypass installation. Here are several recom-
mended suggestions to help:
1.
Form the wire loops (3 or more complete loops) before mounting
the loops to the ignition switch. Form the wire loops around a
similar sized socket or tube to the ignition switch. Use 2 or 3
PLASTIC cable ties to help the wire loops keep their shape. Slide
the wire loops off of the socket or tube and then mount the wire
loops around the ignition switch. (Keep in mind how the steering
column cover fits over or around the ignition switch when
deciding on how large the loops should be or how they should
be attached.) Electrical tape, plastic cable ties, hot melt glue or
silicone glue are good ways to attach the loops to the ignition
switch pick-up antenna)
2.
When routing the wires from the loop that you just made back to
the module, keep them from running parallel to other wires in the
steering column. Interference from these other wires may effect
the transponder bypass performance. (Do keep in mind how you
are routing the wires especially if the vehicle is equipped with a
tilt steering wheel. Make sure the transponder loop wires do not
interfere with the up and down, and left and right motion of the
steering wheel.)
3.
Make sure the transponder loop wires are long enough to reach
the module when the module is mounted under the dash when
the installation is complete. If the transponder loop wires are not
long enough, cut and carefully splice just enough extra wire in
the transponder loop to reach the module (any similar gauge wire
will do). Make sure your connections are well made and carefully
taped to insulate the wires.
4.
If the transponder loop is well placed and the vehicle will still not
properly remotely start (generally the THIEF or SECURITY light
on the dash is flashing when the remote starter is attempting to
start), try flipping or rotating the key inside of the module.
Transponders can be directional and sometimes tricky to find
their “sweet spot”.
