JDC Posted February 28, 2007 Report Posted February 28, 2007 Managed to snap my key in my d-lock and messed up the lock in the process. What can I do to open it so that my bike isnt chained outside my office till the end of time. Do the police do this kind of stuff? Quote
kevob Posted February 28, 2007 Report Posted February 28, 2007 use a cordless drill and drill into the lock where the key goes gradually using bigger bits untill the lock pops open should do the trick Quote
cassiewoofer Posted February 28, 2007 Report Posted February 28, 2007 Did this at work myself......an angle grinder will take about a minute,makes lots of sparks and you need an extension lead from work. I've heard that cooling with a plummers spray, (after removing plastic) will make it brittle enough to crack with hammer but not tried this. Quote
raptor Posted February 28, 2007 Report Posted February 28, 2007 if you use any of the methods above then the lock wasn't worth buying. angle grinding through should be the easiest option. or just go and buy a new one Quote
Duderino Posted February 28, 2007 Report Posted February 28, 2007 I've heard that cooling with a plummers spray Does that really mean p iss onit ???? Quote

If you can cut through the bike lock with an angegrinder in a minute its not wort having, D_lock are nutoriously bad locks. most locks will be or should out of reinforced steel which is very tough and shouldn't be easily cut up, would need a lowspeed cutoff saw and lots of lube. We use hardend steel at work and it eats up saw blades. Quote

You would think so, but when I lost the key to my bike lock that I used to lock the front wheel to the frame in my garage I was shocked how easily the angle grinder went through it...hot knife & butter sprang to mind:eek: Quote
Anne1599968726 Posted February 28, 2007 Report Posted February 28, 2007 Tell you what mate, you can have mine. The lock fell out of it. Good old Halfords. Quote
doz smith Posted February 28, 2007 Report Posted February 28, 2007 they are not particulary high security devices, they are just meant to take long enough to cut through that people wont bother. drilling the lock will be a mare i expect, i think i would go for a grinder, maybe nice fireman will lend you a chop if he is near, intrested to know if a jack in the center works, i would worrie that the thing is maluable and you just end up crushing the tube on your bike. Otherwise you are going to have to hack it, as to the think becoming brittle i would not think that is likely, it may fatigue (SP) after several 100 thermal cycles but i would guess if freezing it worked then hitting it with a hammer would have worked anyway.

Furry Ginger One Posted February 28, 2007 Report Posted February 28, 2007 Give the local fire service a call and tell them you will pay a few quid to a charity of their choice. They WILL get the lock off. Quote

I don't know but it might be why they don't sell cordless angle grinders in B and Q! Steve....like the car jack idea...I'll have a go at that, with some seriouse P.P.E. on!! (i've got about 5 D locks from ages back that i've lost the keys for....er and the number they give you on the key! ) Quote

Thing about angle grinders is you need extension lead and a power supply and not many theiving kid scousers have got that! D locks are hardened steel try a hacksaw on them and the teeth just wear down till they're round, doesn't even scratch the surface of the D lock. Quote

Morgan Posted February 28, 2007 Report Posted February 28, 2007 you can get some nice battery anglegrinders we had a dewalt one cost a fair packet but was nice then again if your a theif you could nick one and carry it around steal a good few bikes lol If you can cut through the bike lock with an angegrinder in a minute its not wort having, D_lock are nutoriously bad locks. most locks will be or should out of reinforced steel which is very tough and shouldn't be easily cut up, would need a lowspeed cutoff saw and lots of lube.

cassiewoofer Posted February 28, 2007 Report Posted February 28, 2007 TBH i was pleased when i discovered they had none in B&Q i assumed they were somewhat controlled or not for sale in this country. I'll look on googleoogloo:) bit costly! http://www.toolshopdirect.co.uk/ishop/982/shopscr4972.html interesting article here http://www.slate.com/id/2140083 Quote
happytechie Posted February 28, 2007 Report Posted February 28, 2007 the way I've see it done is by picking the bike up and twisting it round... the extra leverage you get with the bike fame is enough to render the lock worthless. Quote
cassiewoofer Posted February 28, 2007 Report Posted February 28, 2007 In sheffield a whaile back i heard they were just hacksawing through the frame! on a lightweight steelie that would take seconds! obviously only going for the quality components! might have to invest in one of these! http://images.google.co.uk/imgres?imgurl=http://www.kryptonitelock.com/articles/2789/997986_nyf_200.gif&imgrefurl=http://www.kryptonitelock.com/inetisscripts/abtinetis.exe/PublicArticleDetails%40public%3Fartid%3D2789%26atf%3Dproducts_item%26pgrp%3D20&h=250&w=200&sz=16&hl=en&start=6&tbnid=i6Ei9hILl1QvCM:&tbnh=111&tbnw=89&prev=/images%3Fq%3Dfahgettaboutit%26svnum%3D100%26hl%3Den%26sa%3DN Quote
JDC Posted February 28, 2007 Author Report Posted February 28, 2007 Cheers for the info so far - for reference its the Kryptonite KryptoLok STD U-lock on http://www.slate.com/id/2140083 posted by cassiewoofer - cheers for that. Looks like its not the most sturdy and Ive got a big hammer. Failing that angle grinder seems to be the most popular option. Quote

I thought the point of this was for the chavs in question to end up with a bike frame to sell.... anyway, I always use two locks on my bike at the office, one's a hardened steel cable in a rotating steel sheathing (to stop hacksaws) with a padlock, the other's just a cheepo halfrauds d lock but it looks big and solid. I don't know if either of them would stand up to a night outside mind you. Quote

I've heard that cooling with a plummers spray, (after removing plastic) will make it brittle enough to crack with hammer but not tried this. Plumbers spray or CO2 fire extinguisher - spray on and whack it really hard with a big hammer...Job done. (oh, wear eye protection!) Quote
Active-8 Posted February 28, 2007 Report Posted February 28, 2007 car jack every time. it will be open in seconds Quote
Mr. F Posted February 28, 2007 Report Posted February 28, 2007 As Steve and A-8 have said.....Use a car jack. It works, I've done it. Quote
cassiewoofer Posted February 28, 2007 Report Posted February 28, 2007 depending on how it's locked though you can't always get the jack in there correctly but i know it will do the job, car jacks are Quote
