Combination bike lock

    OK, here's a poser for you all.

    Many years ago (seems like soooo many), we bought Vicki a combination lock bike chain. She's had another bike, still used the lock, but the bike has sat in the garage now, unused for about 6 years! I'm starting to clean it up, service it and see if it will be usable for her when she goes to college.

    You can see the problem coming can't you?

    The bike chain is done up around the saddle stem (ok, I can remove this and get the lock off), but when I ask her, I know she'll just say "well I don't know" when I ask her for the combination.

    So, any experts out there who know how to crack this combination or do we have to go out and buy a new one?

    It MAY be possible to crack if it's a little worn....

    Turn each barrel/lever one step at a time, and gently 'rock' it. If it feels 'looser' at a certain digit, that may be it - or not.

    Good luck. :tup

    Take it to any locksmith and they'll crack it for you. I could probably do it, but won't sy how on a public forum. I'll pm you.

    I assume you have tried the obvious ones

    0000
    date of birth etc !

    Have tried this and so far, failed. :(


    Thanks for the PM, have replied back, but again, so far have failed. :(

    There is no 0000. It goes 1 - 7 and a dot, but no 0. We didn't do date of birth because that would have been too easy for kids to sus out. We thought we did some sort of sequence, of 1, then 1 add 1, add 2 etc, but that hasn't proven to be the case.

    Not to worry, it ain't gonna break the bank to pick up another, I just don't like to admit defeat in a challenge. :rolleyes::tongue:

    Just go through them all in order. I did this with an old computer lock once and managed to find it pretty quickly.

    I'd buy a new one anyway - a combination lock is no deterrent at all to thieves.

    Get a D-lock, with solid metal all around. Heavy, and more expensive, but better than having your bike nicked.

    Cheers Dave, will look into that. :tup

    She's off to Cardiff, which apparently one of UKs safest cities.

    A combination bike lock can be forced pretty quickly - if it has 7 numbers per rotor and 4 rotors there's only 840 combinations, 10 mins work at most. If only 3 rotors it's only 210.

    Why don't you take it to Blackpool at the weekend and give it to one of the men in the box. I'm sure they'd appreciate having something to pass the time and take their mind off the music ;)

    Humph, I had a bike once where chummy kindly managed to unlock the D-lock and took the bike away. He kindly left me the lock though! :mad:

    In fairness, it was quite an old D-lock, and probably nowhere near as secure as the newest ones.

    Actually, no I haven't. :) Buuut now you mention it, the day I took her for her audition last year, there were Police (and lots of them) on every junction (or so it seemed). They were parked in the middle of streets on hashes and were all out of their cars on the lookout. Felt quite intimidating at the time, but then someone mentioned something about Torchwood and an explosion scene being recorded or something.

    Is she going to the RWCMD?
    If so, will she be living in the RWCMD Halls?

    Got a list of those 840 combinations I can start on? :tongue:

    Yes and yes.

    Thanks for the PMs and tips guys. I've watched Youtube videos until I'm going crazy. Our lock doesn't seem to either have the movement that theirs do, "click" like theirs or have resistance like theirs. Ho hum, back to the drawing board.

    (Or the bike shop). :rolleyes:

    The RWCMD Halls are quite good, have you received the pack about them yet?

    Yup, just finished filling the forms in, sat in an envelope on the desk waiting to be posted.
