Query: Lock stuck, thankfully outside computer

I had this and liked it until one day it just stopped opening and closing. Thankfully it was outside my computer so I'm just buying a new one. I tried WD40 and nothing, stuck. I just went to Staples and Best Buy (ridiculous) and this is the only lock both carry so I'm on Amazon buying a new one. I thought it might have just been me but it was redeeming to see the low rating on amazon. How are they still selling this?
