“Just a little difficult finding the key I needed because I was putting a space in the ID. That is, I was typing "HW 104". When I removed the space, I found it immediately.”

“New cabinet arrived, unlocked cabinet, dropped keys in so they wouldn’t get lost, closed cabinet and drawers locked. Cannot get a human in customer service so now have to pay $15 for a new key due to the malfunction of the lock. Not a good experience. ”
