So why not bring that convenience to heavy machinery? With enough doors and panels to fill a small building, operators would surely benefit from having one key that opens all of them. However, reality gets complicated when each panel is a different size with a different latch specialized to secure it. These latches often have limited head styles for tool operation, so you get one vehicle with a full key ring of tools needed to access it. The last thing an operator needs in the field is more stuff to carry.
