Chevrolet Impala 2006-2013 Key Programming Procedure
The following are the key programming procedures for the 2006 and 2013 Chevrolet Impala.
ADD DUPLICATE KEY (Requires at least one working key):
1. Verify that the new key has “PK3” or “+” stamped on it.
2. Insert the original, already programmed key into the ignition lock cylinder and start the engine. If the engine will not start, see your dealer for service.
3. After the engine has started, turn the key to LOCK/OFF and remove the key.
4. Insert the key to be programmed and turn it to ON/RUN within 10 seconds of removing the previous key. The security light will turn off once the key has been programmed. It may not be apparent that the security light went on due to how quickly the key is programmed. (If your vehicle does not have a security light (04-07 Grand Prix, Bonneville, Impala), wait 10 minutes 45 seconds to make sure the key has been programmed).
5. Repeat steps 1 through 4 if additional keys are to be programmed.
About Chevrolet Impala
In its ninth generation, the Impala was once again offered as a police car. The 9C1 and 9C3 models were based on the LS model but included steel wheels or steel wheels with wheel covers, optional rubber flooring, preparation for police equipment such as sirens, radios, lighting, special badging, inoperable rear door handles, windows, and door locks, and inoperable rear door handles, windows, and door locks. A back vinyl bench seat, as well as front cloth bucket or bench seats, both cloth front and rear seats, or vinyl front and rear seats, were available. It also included instructions for installing a criminal cage between the front and rear seats. Fog lamps were optional on the LT, LTZ, and SS in 2008, and they remained so until 2012.
The spoiler shown on the LT and LTZ was also an option on the 9C1 and 9C3 until it was replaced by the spoiler seen on the SS in 2009. In 2007, the Impala received Active Fuel Management as a standard feature. In 2008, the police sedans were given FlexFuel capability to compete with the Ford Crown Victoria Police Interceptor, which acquired a similar feature allowing it to run on E85 as well. The 3.9 L (237 cu in) V6 combined with the heavy duty 4T65E-HD gearbox and standard dual exhaust were utilized in the Impala 9C1 and 9C3 versions from 2006 through 2011. The SS radiator and cooling system was used to replace the conventional 3.9 L engine in Police Sedans (used in the Impala LTZ).
The heavy-duty steel wheels, meanwhile, were not redesigned. Instead, the Police Sedan retained the original center caps or the earlier type wheel covers from the 8th generation vehicle. Starting in 2008, the 9C1 and 9C3 received an exterior trunk lock tumbler, which was not available on the civilian version of the automobile. For the 2006 model year, the standard wood grain was used on the 9C1 and 9C3 police vehicles until 2007, when it was replaced by aluminized interior trim. The imitation carbon-fiber inside trim was installed in 2010 to replace the aluminized interior trim. Both the 9C1 and 9C3 received a 2012 model year facelift that included fog lamps, brake cooling ducts not present on civilian vehicles, body colored external trunk trim, larger 17-inch wheels with new wheel covers, and the same LFX V6 as the civilian Impala mated to a six-speed automatic transmission. The ninth generation Impala 9C1 and 9C3 remained in production as the Impala Limited when the tenth generation Impala was announced, with a “Limited” emblem on the trunk. The Impala 9C1 was replaced by the Caprice PPV after manufacture stopped in 2016. Previously, the Caprice 9C1 and Impala 9C1 were available at the same time.
