Last night, my son went to grab something out of the car so I dont know what he did but when my wife went to use the car, all the doors were locked. The headlights were on. The car was not running. We were unable to unlock the doors with either remote. I believe it would beep 3 times but wouldnt unlock. I had to use the key built into the remote to get the doors unlocked. Any idea what this issue is?
The 12V auxiliary battery is probably near-dead and needs to be either recharged (if it will hold a charge) or replaced.
