- Ford Motor Company 2000 Mercury Grand Marquis Owner's Guide

You will need to have two previously programmed coded keys and the

new unprogrammed SecuriLocky key readily accessible for timely

implementation of each step in the procedure. Please read and

understand the entire procedure before you begin.

1. Insert the first previously programmed coded key into the ignition and

turn the ignition from OFF to ON (maintain ignition in ON for at least

one second).

2. Turn ignition to OFF and remove the first coded key from the ignition.

3. Within five seconds of turning the ignition to OFF, insert the second

previously programmed coded key into the ignition and turn the ignition

from OFF to ON (maintain ignition in ON for at least one second but no

more than five seconds).

4. Turn the ignition to OFF and remove the second coded key from the

ignition.

5. Within 10 seconds of turning the ignition to OFF, insert the new

unprogrammed key (new key/valet key) into the ignition and turn the

ignition from OFF to ON (maintain ignition in ON for at least one

second). This step will program your new key to a coded key.

6. To program additional new unprogrammed key(s), repeat this

procedure from step 1.

If the programming procedure was successful, the new coded key(s) will

start the vehicle’s engine. The theft indicator (located on the instrument

panel) will light for three seconds and then go out.

If the programming procedure was not successful, the new coded key(s)

will not operate the vehicle’s engine. The theft indicator will flash on and

off. Wait at least one minute and then repeat the procedure from step 1.

If failure repeats, bring your vehicle to your dealership to have the new

spare key(s) programmed.
