Open A Padlock With A Soft Drink Can

Most us who've had school lockers or rental storage units know that lots of people trust inexpensive padlocks to secure their belongings. Tactical studies weblog ITS Tactical proves that this trust is a false sense of security by opening the two most popular type of padlocks with shims cut from an aluminium soft drink can.

Combination padlocks tend to only lock on one side while keyed locks usually have a double-lock shackle. To open a single shackle lock, you create a shim by cutting out a piece of aluminium shaped like the letter M. The middle indentation of the shim is inserted in the space between the lock body and shackle and then the shim is turned while working the shackle up and down until the shim has moved around to the other side of the lock into the mechanism. Once the shim is there, use it to push the locking mechanism out of the way and open the lock.

The process is the same for a double-lock, but you must shim each side. This is one of those activities that is easier to explain by watching the above video.

Finally, neither Lifehacker nor ITS Tactical advocates any illegal actions and this post is for informational purposes only so you may learn how unsecure the most popular padlocks actually are.

How to Open a Padlock with a Coke Can [ITS Tactical]


    This is crazy! I am never using these silly locks ever, scary how easy that was....

    Great, now I have to change my locks to something that locks differently, goddammit, why... why?

      +1 Oh yes, I definitely agree with you there, shenanigans!

        Bugger, this was obviously meant for 'Inform'

    The double bolted lock in his video isnt unlocked using his 'shim' method. He conceals the key in his hand as he twists...

    Thats why he leaves and comes back at the start and throws the lock out of view when its unlocked

    After he failed first, second time he hid the key in hi hand and triggered by locking key with pinky in palm and turning lock in his hand. The combo lock trick he may have slipped the combo when unlocking or it was just a weak lock.

      You just repated what I said? - but anyway.

      Yes th combo lock is a weak lock - you can tell because when he throws it about and plays with the bolt it has a "tin"/"hollow" sound to it - quality combonation locks are mostly solid in order to reduce the failrate when putting in the combonation.

      These videos are making me wonder if you actually watch them Giz? Or even read the comments on them?

    I've tried this before, didn't work.

    El cheapo small locks are only to keep honest people out of a place which contains items of very little value.
    A well-built lock for serious security purposes requires a locksmith to open it, or a criminal with a battery operated angle grinder, or other cutting tools for hardened steel shacles.
