Product review (3 stars): Look not fool proof!
The unit does not have an actual lock but rather a rod and pen style that is not very secure.  We purchased this unit for a hotel continental breakfast and someone was able to access it the very first night to steal food.  You can turn the lock with your fingernails and even just lift the door to move the rod out of the hole.  With this being a commercial unit, not to mention the price, I expected a real lock!  We had to modify it in order to use it.  I contacted Summit directly and there was nothing they could do.  I didn't give a complete negative review because it does look aesthetically pleasing and cools to expectations.  I would not recommend this unit for a hotel that is not monitored 24/7.
