Mercury Montego 2007 Key Programming Procedure
The following are the key programming procedures for Mercury Montego for the year 2007
ADD KEY (Must have two working original keys):
1. Insert the first previously programmed coded keys into the ignition.
2. Turn the ignition from the 1 (LOCK) position to the 3 (RUN) position. Keep the ignition in the 3 (RUN) position for at least 3 seconds, but no more than 10 seconds.
3. Turn the ignition to the 1 (LOCK) position and remove the first coded key from the ignition.
4. Within 10 seconds of turning the ignition to the 1 (LOCK) position, insert the second previously coded key into the ignition.
5. Turn the ignition from the 1 (LOCK) position to the 3 (RUN) position. Keep the ignition in the 3 (RUN) position for at least 3 seconds, but no more than 10 seconds.
6. Turn the ignition to the 1 (LOCK) position and remove the second coded key from the ignition.
7. Within 20 seconds of turning the ignition to the 1 (LOCK) position and removing the previously programmed coded key, insert the new un-programmed key (new key/valet key) into the ignition.
8. Turn the ignition from the 1 (LOCK) position to the 3 (RUN) position. Keep the ignition in the 3(RUN) position for at least 6 seconds.
9. Remove the newly programmed coded key from the ignition.
If the key has been successfully programmed, it will start the vehicle’s engine and will operate the remote entry system (if the new key is an Integrated Keyhead Transmitter). The theft indicator light will illuminate for 3 seconds and then go out to indicate successful programming.
If the key was not successfully programmed, it will not start your vehicle’s engine and/or will not operate the remote entry features. The theft indicator light may flash on and off. Wait 20 seconds and you may repeat Steps 1 through 8. If the failure repeats, bring your vehicle to your authorized dealer to have the new key(s) programmed.
To program additional new un-programmed key(s), wait 20 seconds and then repeat this procedure from Step 1.
About Mercury Montego
Mercury brought back the Montego moniker for the 2005 model year, following a 28-year absence from the market. The Mercury Montego, the company’s answer to the Ford Five Hundred, went into production on July 12, 2004, marking the third generation of the model. Along with the 2006 Milan, the third-generation Montego was released to the market as a replacement for the Sable and is positioned below the Grand Marquis.
In place of the Five Hundred’s three trim levels, the Montego had only two: Luxury and Premier, which were interchangeable.
Montegos of the third generation were built at the Ford Five Hundred and Ford Freestyle assembly plants in Chicago, Illinois, where they joined the Ford Five Hundred and Ford Freestyle, the latter of which was a CUV wagon that replaced the Taurus/Sable station wagon.
The Ford D3 platform served as the foundation for the third-generation Montego. The D3 chassis, which was developed in partnership with Volvo, is the first full-size Ford platform to be equipped with front-wheel drive (or its optional all-wheel drive). As a departure from the body-on-frame Panther platform, the D3 chassis is constructed of a single piece of aluminum. The Montego was only two inches shorter in wheelbase than the Grand Marquis, but it had a curb weight that was nearly 500 pounds lower.
The Montego was powered by a single engine that was shared with the preceding Taurus/Sable models: a 3.0L DOHC Duratec V6 with 203 horsepower, which was also used in the Taurus. Front-wheel drive versions were fitted with a 6-speed Aisin AW F21++ automatic transmission, whereas all-wheel drive variants were equipped with a ZF CVT transmission.
