I'm having a new issues with my comfort access tried locking the door as normal with key in pocket and it didn't work.

Now I can only open and unlock when key is above windshiled or above back window, it's flaky if I'm next to the car and hold it above my head, and if leave the keyfob on the roof sometimes I can lock and unlock via door handles.

I did change the battery today in the keyfob and same results, and my battery for the car was changed a few months ago.

I only have one key.

Any ideas bad antena?

Bellow are the parts list for this CA anyone have any ideas of troublshooting this one?
