One NOS PK3 or Circle Plus (+) transponder key blank for a 2009 Cadillac BRX. This key has a black plastic key bow or head and says 'GM' on both sides. The key is identical on both sides. This key was made in USA.

This key is a blank, so it requires having it duplicated to work in your vehicles locks, and have your vehicle's computer configured to recognize the new key. See the onboard programming instructions below:

ON-BOARD PROGRAMMING
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.
