Automatic Arming; Automatic Disarming - Lincoln MKZ Hybrid Owner's Manual

Locks and Security
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.

Automatic arming

The vehicle is armed immediately after turning the ignition off.

Automatic disarming

The vehicle is disarmed immediately after the ignition is turned on.
Replacement of integrated keyhead transmitters (IKT) and coded
keys
Note: Your vehicle comes equipped with two integrated keyhead
transmitters (IKTs). The IKT functions as both a programmed ignition
key that operates all the locks and starts the vehicle, as well as a remote
keyless entry transmitter. A maximum of eight coded keys can be
programmed to your vehicle; only four of these eight keys can be IKTs
with remote entry functionality.
If your IKTs or standard SecuriLock coded keys are lost or stolen and
you don't have an extra coded key, you will need to have your vehicle
towed to an authorized dealer. The key codes need to be erased from
your vehicle and new coded keys will need to be programmed.
Replacing coded keys can be very costly. Store an extra programmed key
away from the vehicle in a safe place to help prevent any
inconveniences. Please visit an authorized dealer to purchase additional
spare or replacement keys.
