Q: Why does the auto-lock feature not work anymore? on 2009 Toyota Camry

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
The auto-lock system(which used to lock the doors when the shifter was put into drive or unlock the doors when the shifter was put into park)is no longer working. Can anyone tell me if this is any easy fix, such as a fuse or relay? Or do I need to take it to a dealer?

I'm not 100% certain on this particular car, but 99.9% -- this should be a programmable feature. Consult your owners manual, or check with a local dealership to get some assistance. Hopefully it will be easy and painless.
