Just wondering if the "imobilizer" system in the car is super sensitive to the car's battery charge? My car's battery is about 4 yrs old and seems to start the car without any issues.

IF the battery easily starts the car, is it possible that the imobilizer STILL might not have enough power to receive the radio signal from the FOB's buttons? OR MAYBE the "imobilizer" has nothing to do with the locking/unlocking. OR MAYBE a bad antenna somewhere for the "imobilizer"?

Just trying to think why both of my key FOBs have stopped locking/unlocking the car?
