So my aging kryptonite D lock is currently at work with my bike still attached to it. The key turns half way before getting stuck, Â and it was working fine until this point. Half an hour of jiggling and swearing didn't shift it. Going to ride over and hit it with the wd40 in a minute but other than bolt cutters + new lock does anyone have any other gems of wisdom that might help here? Or recommend a new reliable lock that will spend it's life outside but undercover?
Is the key going all the way in?
My wife's did the same last year. I flushed it out with WD40 and it's been fine since.
Yeah, shove in a load of wd40 and jiggle baby
(strangest...)
If it works, then get something a bit longer lasting in there to keep the weather off the mechanism
Stick some santa cruz decals on the bike and wait a few minutes....
Give the shackle a good clout, it could be binding the lock. Also beware of the old 'disable the lock' or someone 'accidentally locking their bike around yours' forcing you to leave it overnight when someone can nick it undisturbed.
WD40 should do it. LBS is going to get me a new one under warranty.
Has someone superglued it so they can come back at their leisure and nick it?
As above, wd 40 works when mine sticks
Also as above when mine sticks is usually one of the cylinders (not sure if that's the right terminology is stuck out of line with the rest (key won't go all the way in) so after WD40, a thin jewelers /electricians screw driver (or similar thin thing) can be inserted into the barrel to tease the offending cylinder into line with the rest,, which allows the key to go all the way in again.
Normaly happens on the bottom one on mine so the key looks like it's all the way in as a casual glance but it's not quite..a torch and a look down the key hole might help see what's going on
Also on mine if you if you put the key in upside down it will turn a bit then jam so make sure you try the key both ways.
Thanks for the suggestions, wd40 on its way. Key seems to go all the way in, not been tampered with for thievery I'm pretty sure. Actually the power tap pedals are probably more valuable than the bike itself! I'll look into warranty if lock oil doesn't make things more reliable.
By a country mile the best penetrating fluid is dot4 brake fluid.
I once took an angle grinder to customer's work car park when his new one jammed, that sorted it (Abus I think).
I've had a few Kryptonite locks that do this. Is the key definitely all of the way in? When mine did the same thing, someone recommended inserting a blade edge into the lock (such as a small screwdriver) to align the barrels within the lock. Looking into the lock, you can sometimes see that the top of the key barrel will be at 90 degrees to the level below.
Not sure I'm using the correct technical terms, but it worked for me. I just used the screwdriver to turn the top layer, to line up with the layer below.
Is it really your bike and lock?
How do we know you're not an incompetent scally, asking for advice about how to improve your scally skills? 😉
With mine, if the yellow plastic cover on the straight bar is even slightly rotated then it won't unlock (if that makes sense). I just need to turn it a mm back in line and then it works. No idea why this happens
