Automatic Locks

I have manually cranked windows, not powered ones. There are motors that are driving the locks to lock/unlock when this happens, but I do not have any buttons within the Yaris that I can press to lock/unlock all or any doors. Before this all started happening, I would have to manually lock/unlock each door.

It appears to me that the problem is controlled rather than intermittent, I just don't know how it was induced/started. If it was due to shorted/stripped wires, wouldn't I see it more as an intermittent issue in the beginning rather than it happening consistently all the time like I'm seeing right now? Thanks!

I would be surprised if an aftermarket keyless entry system was installed. I bought the car new from the dealer with ~20 miles on it. When I installed foglights a few months back, I didn't come across any wires or assemblies that seemed out of place or any that appeared to be aftermarket. Do you know off-hand if the newer/older models have that as feature? If so, which ones? Thanks!
