WARNING: This page is about a different car, the 2010 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.

Verify that the fob/key is the correct fob/key for the vehicle.
- If not the correct fob/key, replace the fob/key.
Place the fob/key on the test pad of the J 43241 and press each fob/key button one at a time. The tester should sound a tone and illuminate a green light with each button press.
- If one or more buttons does not sound the tone and illuminate the green light, replace the fob/key battery and retest with the J 43241. If the condition continues after battery replacement, replace the fob/key.
Operate the fob/key while observing the scan tool Fob Function parameter for the appropriate fob/key. The parameter should correspond with the function selected on the fob/key.
- If the parameter does not match the function selected on the fob/key, replace the fob/key.
Attempt to learn the fob/key, refer to Replacing/Adding Keys. The fob/key should learn.
- If the fob/key does not learn, test the keyless entry antenna for an open/high resistance. If the circuit tests normal, replace the K9 BCM.
