    i lost a key to a commercial washer coin box.,help

    So let me see if I got this straight...

    PRICE OF KEY DUPLICATING ACROSS THE GLOBE:

    Australia:  $10
    Canada:   $4
    Walmart:  $0.10
    K.S.A.:       $1.30
    fortunare's hometown:  $0.79

    What I learned from all this: Get your real keys made at Walmart or fortunare's. Don't buy keys in Australia. Zaphod Beeblebrox likes pudding (or just likes saying the word "pudding"). Xacto knives are like 5 bucks for a set of 3 (blades included). And when reading the comments section for any site, no matter what the post is on, you'll always, ALWAYS find somebody who has a problem with it.
    I like the satisfaction of acquiring know-how, even if it's for something impractical or just for fun. At the very least, somebody could incorporate this into a cool spy movie!!

    "And when reading the comments section for any site, no matter what the post is on, you'll always, ALWAYS find somebody who has a problem with it."

    Ain't that the truth!

    Back to the topic at hand, you might need to anneal street sweeper bristles before bending then into a tension wrench or they may break. Hold the bristle with pliers and heat the section to be bent with a flame (only takes a second or two with a propane torch), let it cool then do your bending. If the bristles are used they will be really cruddy, so clean/scrape/scrub/sand them thoroughly before sticking 'em into any lock you care about.

    Also Most Windshield wiper blades contain a nice piece of steel that can be ground down to make a nice turning wrench.

    in Canada, it costs $1.5 for the knife((3blades included) which is similar with the Xacto knife in dollar store.

    Yes, thin soda can like Aluminum.
    If too thick the key will not fit in the Key way.

    In theory would you be able to make a new key for a lock that you have a similar key for, like my grandfathers luggage, in this way? I would love to be able to have a key for it.

     i'd really like to see a receipt for this alleged $.10 key copy. they are at least a dollar most places these days, usually more.

    Yeah, in Aus, a (bad) blank key for $1 is a good price, then expect to pay ~$10 for the actual cutting, if not more.

     Wow, that's insanely expensive, it's maybe 3-4 bucks including cutting in Canada.

    WOW, here in the USA, last time I went to go make copies of the bathroom keys at my work, I got 3 keys made, and it was only like, $2.50.

    most things are.

    Video games that sell in the US for $40 sell for $110 in Aus.

    Programmable chips (MCUs) sell for $2.60 - $4 in the US and $15 in Aus.

     I K.S.A i pay $1.3 a key cutting any key except those need programing.
    And I purchase XBOX 360 Games for $4.05 anyone including recent releases

    Yes, I was also wondering how a key copy could ever cost $.10. Even a nickel doesn't have as much metal than in a key copy, in addition to the energy used to manufacture a copy.

    Sweet! How long does it last? My dad always looses his keys, this could help him out a great deal. Thanks for posting this.

    Just happened across your instructable, and I find this ridiculously useful. My coworkers are constantly losing the keys to the forklifts at work, making me unable to do my job about half the time.

    1 plastic bottle later and I have my own spare key. Illegal? Probably. But increases productivity!
