2014.5 Camry has no electric

Your fob battery is beginning to die and the car lost the code to communicate with it, at least partially. Continuing to try the fob made the computer launch the security system. I'm guessing you see the security light. That shift override let you get the car going so you could drive far enough to get it serviced. See a Toyota dealer about this, you'll probably have to use them to get out of security mode.

You could also try disconnecting the battery over night. Worth a try but your car may have to learn your drive habits over, so it may drive less like you remember for 100 miles or so.

Thanks for the response. I tried disconnecting the battery but it didn't work. There are no lights at all anywhere, including the security light. Taking it to local shop tomorrow. Hopefully it'll be an easy fix.

Problem solved. It was the connection between the battery and the ignition that was not making contact. It was not obvious on inspection.

Glad you're back up and running. Thanks for posting the fix.
