    I lost my keys, and I need to remove my disc lock. I could try to find a cooperative locksmith, but this is NYC and it would likely run me $200. I'd rather spend the $200 on tools to remove it myself.

    Question is, can you hacksaw through a Kryptonite disc lock? Is there some other method that might work? Liquid nitrogen seems like a troublesome option...

    How about using a dremel with a cutting wheel? Just slide it down to cut the locking pin on both sides and you're good to go. Just be very careful to not cut the brake disk itself.

    How about remove the wheel, then unbolt the disc from the wheel.

    If it's a twin disc wheel, you can wedge something in the empty caliper to keep the pads apart and still ride the bike until you get the lock removed.

    It'll be a lot cheaper to take the disc & lock to the locksmith, than to have him come to you.

    A fine suggestion. I thought about it, but I don't have my tools in the city, and I don't think the GS toolkit is sufficient for removing a wheel. Or is it? I could even just bring the wheel to the locksmith, haha.

    Pneumatic anglegrinder?


    Can you contact the manufacturer of the lock with the number and ask for a new key?

    By the time I get a replacement key I will have amassed an inordinate number of alternate-side parking tickets :)

    Yeah It is,,actually that is the whole point ofa toolkit.

    actually is really easy,you need a 8MM for the calipers(or a big torxs if you bike is from the last two years) 6MM to losee the lock at the axle and a 17MM wrench the same you use for the rear wheel.

    actually if you figure out the proper tool you can just take the rotor,,a Hack saw will not do anything to the super harden steel but a 4 1/2" with a cutting wheel will do just make sure you have your paper with you just in case a cop comes around,or you can always find one of those super well know new york bicycle thieves

    Makita Grinder, I had too remove a full sized kryptonite U lock. Worked like a charm. Probably less than $80 at the local Home Depot. Get a spare abrasive blade as they wear down as you use them. Lots of sparks, cover anything you don't ruin. Good Luck.

    If you never use safety glassesthis is a good reason and a place to start,,also be super carefull of not forcing(bending) the cutting disc in funny angles because they are prone to desintegrate and for sure that is not fun specially on bare skin,,another sugestion is to try to hold the lock as rigid as you can to avoid wasting energy and possible failures..

    is a Five minute job max,,just use you head to avoid problems,and be glad you did not have a Cobra Link then you will be in really big trouble since they much harder to cut

    Should I use a cutoff wheel or a grinding wheel?

    Cutoff is far better because you can cut true the material,,oviuslly you need to cut the smallest part,,aka the U part.

    about drilling the tumbler the new generation krptonite's self lock even if the tumbler is gone to avoid exaclly that.

    just go and get the drinder and big extension cord and all you papers so nobody confuse you with a bike thief

    Mine is ancient and doesn't self-lock... would it be easier to drill? I've got that here, the grinder is in NJ and I don't have any grinding wheels for it. God dammit.

    Grinder is a sure thing. I used a grinding wheel, cuz thats what I had. I think grinding wheels are thicker so you probably have to remove more material to get the job done. I am only familiar with cut off wheels for Dremels and they are not up to this task.

    DITTO on what Ricardo said...GLOVES, LONG SLEEVE SHIRT,LONG PANTS, LEATHER SHOES AND EYE PROTECTION. The sparks will melt right through synthetic running shoes and burrow into your foot(speaking from experience).
