this has to be one of the coolest new inventions i have seen in a long time!
a company made a series of padlocks that accepts the ignition key from your vehicle
if your sick & tired of having a key ring full of different keys for your truck, boat locks,
shed locks, tool boxes, etc... you can now have one key that works them all.
go check out the website to see how it works.
