Ford Mustang Boss 2012 Key Programming Procedure
The following are the key programming procedures for the year 2012 Ford Mustang Boss.
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 Ford Mustang Boss
For 2012, Ford reintroduced the Boss 302 nameplate. The basic 2011 Ford Mustang GT’s 5.0-liter Coyote V8 engine has been improved and was dubbed the Road Runner engine by Ford’s development staff. A forged rotating assembly, CNC ported heads, updated camshafts, and a high flow “runs in the box” intake from the 302R racer are among the upgrades. It generates 450 PS (444 horsepower; 331 kW) at 7400 rpm, which is an increase of 32 hp (24 kW) above the basic GT’s 412 hp (418 PS; 307 kW). When compared to the normal GT, the engine loses roughly 10 lbft (14 Nm) of peak torque. It produces 380 lbft (515 Nm) of torque at 4500 rpm and is equipped with a six-speed MT-82 manual transmission. Carbon fiber plates or an optional Torsen differential are used in the limited slip differential of a solid rear axle with a 3.73:1 differential. Two normal Mustang GT outlets and two side pipes leave on either side of the rear crossover complete the quad exhaust system. The side pipes route the exhaust via metal “Attenuation” discs, which add an extra growling sound to the exhaust. The discs are detachable and come with a spacer plate that is designed to fit aftermarket exhaust dump valves.
The Boss 302 builds on the Mustang GT’s suspension by adding stronger bushings, higher-rate coil springs, and a larger diameter rear stabilizer bar. The front end is lowered 11 mm (0.433 in) while the rear end is lowered just 1 mm (0.039 in) to provide a more raked stance reminiscent of the original. Adjusting the shock absorbers at the shock tower requires the use of a flat head screwdriver. The regular Mustang’s traction control system and electronic stability control programs have been modified to include a new intermediate sport mode that provides increased track versatility.
The aerodynamic package (spoilers, splitters, etc.) is nearly identical to that of the Boss 302R race car. The 19-inch black-alloy racing wheels measure 9 inches wide in the front and 9.5 inches wide in the rear and are paired with Pirelli P-Zero tires measuring 255/40-19 in the front and 285/35-19 in the rear.
Ford produced somewhat more than 4000 Boss 302 cars in 2012 and 2013, with slightly more than 750 of those units being Laguna Seca editions.
