Do they need to access or to remove? If just access to turn the propane on/off a locking mechanism can keep thieves from walking off with tanks but let firefighters, etc. still turn them off.
However I would think a firefighter would rather remove them, so no way to lock unless it used some kind of universal key they had. Kinda like the fireman's switch in elevators.
