ALtoids Key security? Answered

i have an idea for a key security device! altoids tin you would use some batteries, and croduce a current through the key via copper wire. if someone (who knows the location of the keys) decides to take it they'll get a shocking suprise! to safely take the keys, just remove bateryes. oh and you mite have to coat the inside of the tin with something

how about that but instead...A keyhole has a current running through it and if any key goes into it it sents out a shock the same as a taser. And the only key that can open it is some kind of insulated/special metal key
