Anti-Theft Indicator - Ford Mustang 2010 Owner's Manual

started unless a coded Integrated Keyhead Transmitter (IKT)
programmed to your vehicle is used. The use of the wrong type of
coded key may lead to a "no-start" condition.
Your vehicle comes with two coded Integrated Keyhead Transmitters;
additional coded IKTs may be purchased from your authorized dealer.
Standard SecuriLock keys without remote entry transmitter
functionality can also be purchased from your authorized dealer if
desired. The authorized dealer can program your spare IKTs to your
vehicle or you can program the IKTs yourself. Refer to Programming
spare keys for instructions on how to program the coded key.
Note: The SecuriLock passive anti-theft system is not compatible with
non-Ford aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security protection.
Note: Large metallic objects, electronic devices that are used to
purchase gasoline or similar items, or a second coded key on the same
key chain may cause vehicle starting issues. You need to prevent these
objects from touching the coded IKT while starting the engine. These
objects will not cause damage to the coded IKT, but may cause a
momentary issue if they are too close to the IKT when starting the
engine. If a problem occurs, turn the ignition off, remove all objects on
the key chain away from the coded IKT and restart the engine.
Note: Do not leave a duplicate coded key in the vehicle. Always
take your keys and lock all doors when leaving the vehicle.

position, the indicator will flash

indicate the SecuriLock system
is functioning as a theft
deterrent.
• When the ignition is in the on position, the indicator will glow for
three seconds, then turn off to indicate normal system functionality.
If a problem occurs with the SecuriLock system, the indicator will flash
rapidly or glow steadily when the ignition is in the on position. If this
occurs, turn the ignition off then back to on to make sure there was no
electronic interference with the programmed key. If the vehicle doesn't
start, try to start it with the 2nd programmed key and if successful
contact your authorized dealership for key replacement. If the indicator
