This "Shovit Tool" (or Shove It Tool) AKA "Mini Jim" can open many door locks using the old "credit card lock pick" technique.
How to use the Shove It Tool:
Just "shove" the device behind the plunger and and push down and forward, forcing the plunger back into the lock housing. An inexpensive device that belongs in every hacker or operator's tool box.
How do I use it?
The product is excellent,
I was expecting a spring steel, but this one bends and stays bent. Haven't used it enough to know if that's good or not.
Everytime my manager forgets her keys inside the locked office, she calls me like a superhero to the rescue. Then I shove it then everyone goes woaaah. I'm the man!
