However, it doesn’t mean that all combination locks are crappy! Wrapping Up So this idea that all combination locks are crappy is reinforced because they’re used on genuinely crappy cable locks. They can be cut in seconds by a small, basic tool that every bike thief carries.Īnd the thing is: many cheap cable locks use cheap combination mechanisms.
I’ve written many times about how you should never use a cheap cable lock to secure your bicycle. In fact they are most likely to tackle a decent combination lock in the same way they would attack a decent keyed lock: with brute force. And in the street they won’t be able to position the lock in a way that makes even attempting to decode the lock practical. The way to do this (and I’m not revealing anything new here), is to create tension by trying to pull the the lock apart (in the same way as you’d open it) and then slowly rotating the dials in turn until they seem to click into place…īut the thing to remember is that virtually no bike thieves have the patience and skill required to pick the more challenging combination locks. Unfortunately however, the finite number of codes isn’t the only weakness of combination locks… Or pick them without any tools!Ĭheap combination locks are very easy to decode. So while it’s true that combination locks can be opened without any tools at all, by someone without any skill at all (beyond counting), if you’ve got a 4 (or more) dial lock then it’s very unlikely that anyone’s going to defeat your lock in this way. It would actually take much longer, even if the thief had the patience and nerve to persist. And in reality, testing one a second for nearly three hours while hunched over a bicycle in the street is just not practical. So the same nimble fingers would take almost 3 hours to test every combination. However with 4 dials there are 10,000 possible combinations.
