Anti-scan feature
If an incorrect code has been entered seven times (35 consecutive button

The anti-scan feature will turn off after:
• one minute of keypad inactivity.
• pressing the
control on the remote entry transmitter.
• the ignition is turned to the on position.
Unlocking and locking the doors using keyless entry
To unlock the driver's door, enter the factory set 5-digit code or your
personal code. Each number must be pressed within five seconds of each
other. The interior lamps will illuminate after entering a valid keypad
entry code.
To unlock all doors, press the 3 • 4 control within five seconds.
To lock all doors, press the 7 • 8 and the 9 • 0 at the same time. You
do not need to enter the keypad code first. Note: The interior lamps
will turn off.
SECURILOCK PASSIVE ANTI-THEFT SYSTEM (IF EQUIPPED)
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.
The message center will display: STARTING SYSTEM FAULT.
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.
