AMX28 Immobilizer Owner’s Manual
Your AMX28 Immobilizer includes two coded transponder tags. Keep only
one coded tag on your key chain at a time. The second coded tag can be used
as a spare, or for a second driver with their own set of keys. In order to start
your vehicle, a coded tag must be attached to the key chain.
Up to five Prime transponder tags can be added to your AMX28 Immobilizer.
Operating Your AMX28 Immobilizer
Activation
1. Turn the ignition key to the "OFF" position and remove the keys. The LED
Status Indicator will illuminate solid red.
2. When you open the driver door, the LED will begin to flash slowly to
indicate the Immobilizer is armed.
3. If you do not immediately open the driver door, after 20 seconds, the LED
will begin to flash slowly to indicate the Immobilizer is armed. While armed,
the vehicle cannot be started without the coded tag.
Deactivation
1. With the coded tag on your key chain, turn the ignition key to the "ON"
position.
2. The LED will turn off and the engine can now be started.
NOTE: If the LED changes to a rapid flash and the engine will not start,
hold the coded tag near the ignition switch to disarm the system.
Valet Mode
To prevent an unauthorized person from entering programming mode and
possibly adding their own coded tag, you can put the AMX28 into Valet
Mode. In Valet Mode, a valet attendant or service personnel can start the
vehicle while you keep the coded tag in your possession.
To Turn On Valet Mode
1. Turn the ignition key to the "ON" position with the doors closed.
2. Open and close the driver door.
3. Turn the ignition key OFF and then ON three times (OFF, ON, OFF, ON,
OFF, ON). The LED will flash at a medium rate to indicate the AMX28 is in
Valet Mode.
4. Remove the coded tag from your key chain.

To Turn Off Valet Mode

2. Turn the ignition key to the "ON" position.
3. Open and close the driver door.
4. Turn the ignition key OFF and then ON three times (OFF, ON, OFF, ON,
OFF, ON). The LED will turn off to indicate the AMX28 is out of Valet Mode.
Adding/Deleting Coded Transponder Tags
1. Enter the vehicle and close the door.
2. Disarm the Immobilizer. (Turn the ignition key ON with your coded tag on
the key chain.)
3. Remove all transponder tags from the key ring.
4. Turn the ignition key ON, OFF, ON, OFF and then ON. The LED will
begin to flash rapidly to indicate the AMX28 is now in the programming
mode.
5. Hold one of the transponder tags close to the ignition switch. The LED will
change from a rapid flash to slow single flashes to indicate the AMX28 has
learned the one transponder tag. Remove the coded tag from the ignition
switch area.
6.Hold the second transponder tag close to the ignition switch. The LED will
flash slowly two times to indicate the second transponder has been learned
and that there are now two transponder tags in memory.
7. Repeat steps 3 and 4 for any other transponder tags you wish to add to the
AMX28 memory. (You can add up to 5 tags.)
8.When you have finished adding the transponder tags into memory, turn the
ignition key to the "OFF" position to exit programming.
NOTE: Any transponder tag(s) that were not used in this process will be
automatically deleted from the AMX28 memory and cannot be used to
deactivate the Immobilizer.
