Help, D-lock Mmm... locked!

[scotty110788]

I got new D lock from halfords a week ago, only ever tied my bike up in secure car park so weather aint got to it, but it has seized up while in car park (Had to take what people call a "bus" home, square box on 4 wheels, anyway...) tried wd40 and little oil, and about half hour trying to get off but key just wont go more than half a turn, halfords said they ill exchange it but have to take it off 1st, its grade 10 rating, any ideas?

Cut it off. Takes seconds with a big enough chopper.

Or use a pair of pliers on the key for leveredge.

surely if its grade 10 cutting will be a bitch, maybe a little oxy will help?

Have you taken the key out properly and all the cylinders in line. Never force a key, they snap. Try wiggling the key in rotating a little side to side to ensure it goes all the way in.

I have checked cylinders are in line, wiggling, treating it like a puzzle lol i could prob get through the cable but it means I'll have D lock near my crank stil attatched. Gonna try wit my spare keys tomoz. the lock i have is Magnum Plus Mini Shackle & Extender Cable Bike Lock, thanks for all your help aswell guys!

So it sounds like the lock is only attached to the bike? If so, cut through the cable, then take the whole bike plus lock to Halfords for them to solve. Probably worth taking a friend to check you are not using the key wrong first or summat!

If you have only locked the lock to the bike, then you are not using it properly - you should have the lock round the frame plus something solid

Best of luck!

Only a small D lock, getting bigger next week to lock around something solid, using 2 other locks in mean time to keep it safe which i'm glad, do come off. good point, gonna get them to do it haha

Tap the lock section with a hammer or spanner, it might release the pins if they're stuck

 

[david1701]

I was only half kidding about the oxy thing, if you have anyone with portable oxy-acetylene cutting kit they will open it like butter

If you do take it to halfords to sort out I would suggest you take a picky of it first. Particularly the area where they are going to apply leverage. Then if they do do damage your bike you have the evidence if it comes to a claim.

Silly question. Have you tried the spare keys. And give it a dink with a hammer and see if that moves things.

Are you sure no one has messed with it?


Lots of careful wiggling of the key should be able to tell you if there is any movement in the pins/tumblers inside.
Tapping and WD40 does help, sometimes.

If the key is turning, even a part of a turn, then the lock barrel is fine. It is possible the locking pin is stuck so adding lube to the two points where the loop enters the locking bar and then tapping the ends and the locking bar onto the loop might free it.

I have the same lock, I use it to lock my sons bike to mine.. Are you using the main large fobbed key..? I had probs with mine, tried one of the smaller spare keys & it opened immediatly.
Sadly this meant we push our bikes the 9 miles home as couldn't sepearte them.. Ever tried pushing a XL framed bike in unison with a small childs mtb...? Lots of cursing under my breath & several large drinks that evening!!

I opened a stuck padlock this week by pouring boiling water over it on the recommendation of a friend. Worth a go.
