    Locksmith in a box! First time I've seen one of these. I wonder if it disallows copies of certain keys.pic.twitter.com/Oi4Gkeb71k

        @dguido So it gathers your personal info, gets an image of your keys, and it looks really easy to build...Nothing to see here, move along...

        @dguido I hate seeing things like this when I'm so flippin' poor! I can only equate this to a bag of money found next to a dumpster.

        @dguido @hacks4pancakes Brought a do-not-dupe key to a locksmith, told "I can't copy this, but the machine in Lowe's doesnt ask questions"

        @highmeh @dguido @hacks4pancakes I've never actually had a hardware store refuse to copy based on the "do not duplicate" engraving in a key.

        @savagejen @dguido @hacks4pancakes this was a locksmith shop, maybe some code of ethics.

        @highmeh @dguido @hacks4pancakes I've heard that many locksmiths dislike those markings, because they provide a false sense of security.

        @dguido @hacks4pancakes Lets just say, hypothetically, that I might have successfully tried certain no-no keys at my local box.

        @Vintage_Sister @dguido The phrase "no-no keys" is incredibly charming and made my whole night.
