HOW DO I STOP MY CAMERY FROM AUTOMATICLY LOCKING THE DOORS

I would say that it's either a faulty door lock relay or a bad power lock actuator motor. I would start by replacing the relay first. That's the cheaper part. I have heard of people changing out the battery in their car then having the same problem. Apparently in some of the newer Camrys there is a door lock setting mode. Check your owners manual first to see if your car has that feature. If so, you will have to go through the steps to reset the power locks. If you haven't changed or taken out your battery, I would start with the relay.

They can change that at a dealers pretty easy as it is an option when you buy a vehicle. I know cuz I hate it and am going down to have it reset.
