If you talking about using a tow dolly, you dont need to unlock it, if your towing it with all 4 wheels on the ground, then yes at least in the acc position, which means instal a quick disconnect for your battery, that way you can turn the key on and not have to worry about any accessories draining the batt on the ride, and wont need any tools in order to get power back if/when you need to drive the X.
