Last week, the keyfob I had with me stopped working (no wireless functions). The light still comes on but I couldn't lock or unlock anything. I started the car thinking it might be some sort of reset thing and then turned it off. The keyfob started working again. I thought it was just a glitch until today when it happened again.

However, this time, no amount of fussing fixed it. I retrieved the second wireless fob from the safe. It too doesn't work.

Either this is a failure or the security system thinks something is up and is out of sync or something. I really don't know.

Has anyone experienced this before? Both fob batteries are ok. One is around 2.7 volts. The other is 3.0 volts.

Figured it out. It was interference caused by a crappy car DVR camera that stuck on. I noticed it didn't power down when the ignition was off. It was plugged into a hardwired 12v to USB power supply that is keyed on the ignition. It's not radio interference because if I power it on the battery, the keyfob still works. It's only when the camera is turned on and plugged into the USB power supply that it occurs. I tried several other USB powered dash cams and none of the others cause the issue.
