This small key is the heart of a common sense approach to pest control device security. We must have tamper resistant bait stations but they also need to be easily accessed by PMPs. VM products has the right idea. A single key that unlocks the fly, insect, mouse and rat bait stations. Easier for the operator to use and it provides a safety factor since the key itself becomes the handle to open the lid. That way finger tips are not in harms way.
