Key Programming: Ford Mustang 2010-2012
Ford Mustang 2010-2012 Key Programming Procedure
The following are the key programming procedures for the year 2010, 2011 and 2012 Ford Mustang.
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
At the 2004 North American International Auto Show, Ford unveiled a redesigned 2005 Mustang, codenamed “S-197,” based on the new D2C platform. The fifth-generation Mustang’s style is reminiscent of the late-1960s fastback Mustang models. It was developed under the guidance of chief engineer Hau Thai-Tang, a veteran engineer for Ford’s IndyCar program under Mario Andretti, and external styling designer Sid Ramnarace. J Mays, Ford’s senior vice president of design, coined the term “retro-futurism.” The fifth-generation Mustang was assembled in Flat Rock, Michigan, at the Flat Rock Assembly Plant.
Between 2005 and 2010, the base model was driven by a 210 horsepower (157 kW; 213 PS) cast-iron block 4.0 L SOHC V6, while the GT was powered by a 4.6 L SOHC three-valve Modular V8 with variable camshaft timing (VCT) producing 300 hp (224 kW; 304 PS). Tremec T5 five-speed manual gearboxes were standard on base models, with Ford’s 5R55S five-speed automatic transmission available as an option. Automatic GTs used this as well, although manual GTs featured Tremec TR-3650 five-speed transmissions.
The 2010 Mustang was introduced in April 2009 with a revamped body — including sequential LED taillights — and a drag coefficient reduction of 4% on base vehicles and 7% on GT variants. The standard Mustang’s engine stayed untouched, while the GT’s 4.6 L V8 was updated to produce 315 horsepower (235 kW; 319 PS) at 6,000 rpm and 325 pound-feet (441 Nm) of torque at 4,255 rpm. Additionally, new spring rates and dampers were added, as was a standard traction and stability control system on all models. New wheel sizes were also added.
Engines were updated for 2011, and transmission options included the Getrag-Ford MT82 six-speed manual or the Ford-licensed 6R80 six-speed automatic. Electric power steering has supplanted the hydraulic version. The new 3.72 liter (227 cubic inch) aluminum block V6 engine weighed 40 pounds (18 kilograms) less than the previous version. It produced 305 horsepower (227 kW; 309 PS) and 280 lbft (380 Nm) of torque with 24 valves and twin independent variable cam timing (TiVCT). The 3.7-liter engine received a new dual exhaust system. GT models had a 32-valve 5.0 L (4,951cc or 302.13 cu. in) engine (dubbed the “Coyote”) that produced 412 horsepower and 390 ft-lbs of torque. Brembo brakes, as well as 19-inch wheels and performance tires, were available as options.
