I have a 2008 Chevy HHR. On Monday both the key fobs for the keyless entry system quit working. I took both fobs to my local auto parts place where they had a tester and both seemed to work ok. What inside the car receives the signal from the remotes and activates the locking mechanism. All other electronics within the car is working. On Monday we had to have the car jump started when someone left the key in the ignition on Acc setting.

Hey TTEWELL,

There is a 10 amp fuse in the #10 spot in the PDC that needs to be checked, if the battery was low and was jumped it can causes the BCM to go out which operates the alarm system. Here is a wiring diagram and a guide that will help you run some tests and get the problem fixed.

Please run some tests and get back to us so we can continue helping you.

Best, Ken
