“In 2005, the state used grant money to give out thousands of locks to prevent criminals from getting into the tanks. Those tanks are stored at co-ops, and on farm fields across the state. The locks are specifically designed from a company called Tanks-A-Lok.”This locking the tank was successful in that there was apparently a state-wide decrease in the illicit production of meth. But, according to the sheriff, “within the last 9 to 12 months things are picking up again”. The tank lock manufacturer does not understand how the thieves are bypassing the locks.

This is done to ensure that the ‘bad guys’ don’t have the opportunity to take a long detailed look at the device to figure out a way to defeat or by-pass the device.

What was unusual in this case was the fact that the storage tank was protected by a locking device that was apparently left intact. According to the article:
