Keys are expensive and they are often lost, so the solution is to make your own! So how easy is it to make a working key by using stuff that can be found around the home? Well thanks to the guys over at Blue MacGyver it seems that all you need is a drinks bottle, various pieces of plastic, lighter and some sharp scissors. Watch the video to see how its done.
Here we are making a spare key for your wallet out of a plastic bottle, you can also use packaging plastic as on a toy package. On the stiffer plastic you may have to bend the key in the channel to make for a better fit.
