The key I have is a genuine Toyota key with a built-in key fob on it so I'd assume it is an OEM wireless entry.

The light is the small yellow/orange bulb nearer to the center of the hood.

OK. Definitely an odd issue, as the two sides are commoned together where nothing can drive them separately. I would check the connectors that plug into the bulbs.

Doesn't it use 7443 bulbs? with dual filament

The parking light and turn signal are in a dual filament bulb, but the parking lights are commoned together. so if the door lock flashes the turn signals, rather than the parking lights, the problem could be a bulb with one of two filaments gone. If that was the case, the turn signal would not work on that side.
