Another scary lock picking tool for people to think about being used against them is the auto jiggler. Auto Jigglers are basically metal cut outs of car key shapes that are essentially bump keys for cars. There are professionally made sets, and from what I've seen on the internet a relatively easy do it yourself project. One just needs to find the right style of key and wiggle it around inside the car door lock. If they hit the right spot the lock will open , letting them into your car. Like many locksmith tools, these can be used for good or for evil.
I like this video because it shows a little trial and error, but still demonstrates how easily someone can open your car door. This must be one of the reasons for all the new cars being keyless. Though I'm sure that has its flaws as well.
