Step 10Usb thumb drive with spare keys
This section was kinda inspired by this instructable.
Some warnings: This will not fit inside your wallet as is without a bit of tampering to the screw, bolt, head, and the insides of the case. Mine just barely fit. I also did not use washers. If you want to use washers, either use three keys and no usb, or one less key.
Firstly, you'll WANT to make some spare keys! If you do this with your normal set and accidentally mess up a key, you'll be completely screwed!
You will also need a very slim and uniform usb drive like the one pictured. Any other may not fit. It will also need a place on the end where you can actually dremel into without damaging the circuitry, or have a pre-existing hole. Test how well your usb drive will fit by placing it in the lefthand side of the baseplate by itself.
Find a small screw and bolt set that can fit inside a hole created by a 7/64 drill bit and a head that isn't terribly large.
Take each key and your reinforced metal cutting blade on your dremel. Saw off the edges of the key handle till they are even with the width of the rest of the key, then square the handle off by cutting the excess of the key off a centimeter before where the actual key part stops.
Take your grinding tool and soften the sharp edges you got from sawing the key metal.
In the center of each new key head drill a hole with your 7/64 drill bit. My house key was short enough to use the pre-existing hole. Your longest key should not go any further than a millimeter past your usb key end that isn't drilled into.
Get your usb key and and dremel a hole in the end that doesn't plug into your computer. Again, make very carefully sure you do not drill in a place that will touch or damage circuitry.
Put your screw through the holes and then thread on the bolt until it hits the top key. Cut off the excess of the screw and then sand it flat. Place it in the left side of the backplate. Check and see if it will fit and close. It probably won't. If not you'll have to do as I described briefly above. Sand down the head of the screw a bit and sand out a small scoop in the front and back plate where the head and bolt touch until it closes. Be very careful not to sand too much or else you will make a hole in the case that you don't want.
After it fits scuff up the side of the usb that the keys are not on. Cut a piece of velcro and glue them together. Make sure the velcro does not go past the plug in part of the usb and stays about two millimeters away from the head of the screw at least. Place the other side of the velcro where the usb and keys set. Be sure not to place it where the head will touch the case. Put it exactly where the usb and key velcro touches. Also be sure it doesn't go past the imaginary vertical line that the vertical walls create.
And that's it for extras!
