- disposing of transmitter batteries.
- Insert the new battery. Refer to the diagram inside the remote entry transmitter for the correct orientation of the battery. Press the battery down to ensure that the battery is fully seated in the battery housing cavity.
- Snap the two halves back together.
Note: Replacement of the battery will not cause the remote transmitter to become deprogrammed from your vehicle. The remote transmitter should operate normally after battery replacement.
Replacing lost remote entry transmitters
If you would like to have your remote entry transmitter reprogrammed because you lost one, or would like to buy additional remote entry transmitters, you can either reprogram them yourself, or take all remote entry transmitters to your authorized dealer for reprogramming.
How to reprogram your remote entry transmitters
You must have all remote entry transmitters (maximum of four) available before beginning this procedure.

To reprogram the remote entry transmitters:
- Ensure the vehicle is electronically unlocked.
- Put the key in the ignition.
- Cycle eight times rapidly (within 10 seconds) between the 1 (OFF/LOCK) position and 3 (ON). Note: The eighth turn must end in the 3 (ON) position. The doors will lock, then unlock, to confirm that the programming mode has been activated.
- Within 20 seconds press any button on the remote entry transmitter. Note: If more than 20 seconds have passed you will need to start the procedure over again. The doors will lock, then unlock, to confirm that this remote entry transmitter has been programmed.
- Repeat Step 4 to program each additional remote entry transmitter.
- Turn the ignition to the 1 (OFF/LOCK) position after you have finished programming all of the remote entry transmitters. Note: After 20 seconds, you will automatically exit the programming mode. The doors will lock, then unlock, to confirm that the programming mode has been exited.
Illuminated entry
The interior lamps illuminate when the remote entry system is used to unlock the door(s).
The illuminated entry system will turn off the interior lights if:
- the ignition switch is turned to the 3 (ON) position, or
- the remote transmitter lock control is pressed, or
- after 25 seconds of illumination.
The dome lamp control must not be set to the off position for the illuminated entry system to operate.
The inside lights will not turn off if:
- they have been turned on with the dimmer control, or
- any door is open.
The battery saver will shut off the interior lamps 10 minutes after the ignition has been turned to the 1 (OFF/LOCK) position and a door is left open, and in 30 minutes if the dome lamp control is left on and the ignition has been turned to the 1 (OFF/LOCK) position. The battery saver will also shut off the trunk lamps in 30 minutes if the trunk is left open.
SECURILOCK PASSIVE ANTI-THEFT SYSTEM
SecuriLock passive anti-theft system is an engine immobilization system. This system is designed to help prevent the engine from being started unless a coded key 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 keys; additional coded keys may be purchased from your authorized dealer. The authorized dealer can program your spare keys to your vehicle or you can program the keys 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 key while starting the engine. These objects will not cause damage to the coded key, but may cause a momentary issue if they are too close to the key when starting the engine. If a problem occurs, turn the ignition off, remove all objects on the key chain away from the coded key and restart the engine.
Anti-theft indicator

The anti-theft indicator is located in the instrument cluster.
- When the ignition is in the 1 (OFF/LOCK) position, the indicator will flash once every 2 seconds to indicate the SecuriLock system is functioning as a theft deterrent.
- When the ignition is in the 3 (ON) position, the indicator will glow for 3 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 3 (ON) position. If this occurs, the vehicle should be taken to an authorized dealer for service.
Automatic arming

The vehicle is armed immediately after switching the ignition to the 1 (OFF/LOCK) position.

The theft indicator will flash every two seconds when the vehicle is armed.
Automatic disarming
Switching the ignition to the 3 (ON) position with a coded key disarms the vehicle.

- The theft indicator will illuminate for three seconds and then go out.
- If the theft indicator stays on for an extended period of time or flashes rapidly, have the system serviced by your authorized dealer.
Replacement keys
If your 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.
Programming spare keys
You can program your own coded keys to your vehicle. Please read and understand the entire procedure before you begin.
Tips:
- A maximum of eight keys can be coded to your vehicle.
- Only use Securilock keys.
- You must have two previously programmed coded keys (keys that already operate your vehicle’s engine) and the new unprogrammed key(s) readily accessible.
- If no previously programmed coded keys are available, you must take your vehicle to your authorized dealer to have the spare key(s) programmed.

- Insert a previously programmed coded key into the ignition.
- Turn the ignition from the 1 (OFF/LOCK) position to the 3 (ON) position. Keep the ignition in the 3 (ON) position for at least one second, but no more than 10 seconds.
- Turn the ignition to the 1 (OFF/LOCK) position, and remove the coded key from the ignition.
- Within ten seconds of removing the previously programmed coded key, insert the other previously programmed coded key into the ignition.
- Turn the ignition from the 1 (OFF/LOCK) position to the 3 (ON) position. Keep the ignition in the 3 (ON) position for at least one second but not more than 10 seconds.
- Turn the ignition to the 1 (OFF/LOCK) position, and remove the second key from the ignition.
- Within twenty seconds of removing the previously programmed coded key, insert the unprogrammed key (new/valet key) into the ignition.
- Turn the ignition from the 1 (OFF/LOCK) position to the 3 (ON) position. Keep the ignition in the 3 (ON) position for at least one second.
- Your new unprogrammed key is now programmed.
If the key has been successfully programmed it will start the vehicle’s engine and the theft indicator light will illuminate for three seconds and then go out. If the key was not successfully programmed, it will not start your vehicle’s engine and the theft indicator light will flash on and off rapidly. If failure repeats, bring your vehicle to your authorized dealer to have the new key(s) programmed.
To program additional new unprogrammed key(s), repeat this procedure from Step 1 for each additional key.
ACTIVE ANTI-THEFT SYSTEM (IF EQUIPPED)
The active anti-theft system is designed to warn you in the event of an unauthorized entry to your vehicle and is also designed to help prevent the unwanted towing of the vehicle. When the vehicle is locked and armed, the active anti-theft system monitors the following.
- Doors
- Hood
- Trunk
- Movement inside the vehicle
- Change in vehicle inclination
Note: The active anti-theft system includes a motion detection system which monitors the passenger cabin and a vehicle incline sensor which detects changes in vehicle attitude.
The interior motion detection and vehicle incline sensing systems will operate only when the vehicle is locked using the remote keyless entry transmitter or when using the power door lock control with the accompanying door open and all doors then become closed. For convertible vehicles, the convertible top must be in the fully closed and latched position for the interior motion sensing system to arm. If you lock the vehicle using the key in the driver door key cylinder, the system will monitor the doors, trunk, and hood but the motion sensing and vehicle incline sensing will not arm.
Do not arm the interior motion detection system if movement within the vehicle is likely to occur. Additionally, do not arm the vehicle incline sensing system when the vehicle is in transport.
For proper operation of the interior motion detection system, ensure all windows are closed prior to arming the system. This will help prevent accidental alarm activation due to external influences and ensure proper
interior motion detection. Additionally, the interior motion sensing system will not arm if either door or the trunk is ajar.
If there is any potential active anti-theft problem with your vehicle, ensure ALL remote entry transmitters are taken to an authorized dealer to aid in troubleshooting.
Arming the system
When armed, the active anti-theft system is designed to notify you of an unauthorized entry. When unauthorized entry or towing occurs, the system will flash the turn signal lamps and interior lamps and sounds the security horn.
The system is ready to arm whenever the key is out of the ignition. Any of the following actions will arm the alarm system:
- Press the remote transmitter lock control one time to arm the system.
- Lock all doors using the interior power lock switch while the driver or passenger door is open and then becomes closed.
- Lock the driver door with the key in the key lock cylinder (this will not however arm the interior motion or vehicle incline sensing systems or lock the passenger door).
If all the closures (doors, trunk, hood) are closed, the turn signal lamps will flash once. If any closure is not properly closed the parklamps will not flash. Note: Locking the driver door with the key does not lock the passenger door. Use the power door lock control or manually lock the passenger door to ensure the vehicle is properly secured.
The system will wait 20 seconds after locking before triggering an alarm. After the 20–second pre-arm phase, the power door unlock control is disabled (for more information, refer to Power door trim switch inhibit section earlier in this chapter) to further protect your vehicle.
Disarming the system
You can disarm the active anti-theft system by any of the following
actions:
- Unlock the doors by using the remote entry transmitter.
- Unlock the driver’s door with the key in the door lock cylinder.
- Turn the ignition to the 3 (ON) position with a programmed coded ignition key.
Note: Unlocking the trunk inhibits the motion and tilt sensing systems, but the system continues to monitor the doors and hood. Once the trunk becomes closed the motion and tilt sensing systems will re-arm.
