Found this bike lock..Info please?

[Olson Burry]

Hi all! Today I had a find. I found this rather hoofy severed (motor?)bike lock outside a garage near my house so I grabbed it and took it home.

I dug around in the key-way a little and at first I thought they were wafers. I knew they couldn't be so I grabbed a torch and had a good look.

there is one place, right at the back of the key-way that can be depressed and is springy.

Heres what it looks like:



And they key-way, it was nearly impossible for me to get a picture with my phone but this is the best I could do.



I'd like to know what kind of tools are needed or what kind of approach I should take to understand more about how this one works, with a view to picking it open at some point. (is it a disc tumbler?)

If its beyond what members think can be accomplished at home, (or belongs in advanced) I'd like to know as it's a big thing and I'll just chuck it out.

Kind regards

OB

It's a disk detainer mechanism. Picking is advanced material.

Ah, thought so, thanks for the reply.

Just digging through my copy of LSS I more or less get what's inside. heck.

All the best.

Hello again

Today I have planned to take my dremel, grinder, files, saw; whatever it takes to the lock pictured above to get a look at the internals.

I would appreciate any tips or advice - will the dremel cut off disk even go through the cable? We shall see I suppose.

Much appreciated - I'll let you know what happens!

Where safety glasses!!!!!!!!!

Where safety glasses!!!!!!!!!

Where indeed

Seriously though, they are the first thing I put on and the last thing I take off. Cant be too careful with them old eyes

Well i had some success. In my head I kind of knew this wouldn't be the prettiest job in the world. It wasnt.

Bigger pics are available here

The plastic bits came off easy enough:



The inner metal housing proved a little more tricky..



With some "gentle" persuasion it was soon prised loose:



And this came out:



Here we can see the disks and (i assume) the entry point for the sidebar. (also pictured) Whilst in its little housing the sidebar stops the unit from rotating.



All in all its a pretty funky little lock, it certainly provided some amusement for today, as well as needed dremel practice - I only got it the other week and this is the first real use I've had for the cut off disks.

I hope I haven't broken any rules posting this.

Cheers all, happy pickin'

Breakdowns, no matter how high the security level, are always fine Good work getting it down that far. Going to take the leap and pull the discs?

Going to take the leap and pull the discs?

Why the heck not? Here we go:

Photography isn't exactly my forte, also I live in a basement so its a little dark. Tried my best though.

There were two clips holding the discs in which needed to be gently pushed from the back to release them



Here, we see a disc with its metal spacer side by side:



And all the bits: there are 6 discs in all.





Pretty cool thing.

All the best.

very cool =) those pic's look nice and the lock looks like fun to play with >.> wish i had that kinda luck

Looks like you did a good job on getting it apart. You are correct about where the sidebar goes. It also appears to be a one-way mechanism.

[Olson Burry]

Thank you for the kind words.

n2oah: The lock itself only turns through 90 degrees and it doesn't look like it would "lock open" as in the housing there is no space for the sidebar to pop out once it is in the open position. My guess is that in that position, removing the key would be impossible as well. (if that is at all what you were getting at?)

Wolfie: Keep your eyes open mate, you never know when your luck may change

I have to say I was really impressed with the dremel, I used two brown cut off disks at the same time as recommended by the dremel site videos and they lasted for the whole (albeit noisy) job. The metal housing was pretty thick and sturdy.

Also it was a right fiddle getting all the discs and little springs back in and in the right places! It is now back together.

All in all a pretty cool day. Cheers to you all!

Yes, that's what I was getting at. That feature is called "key retaining".

Thanks for the pics. I'm trying to decide whether I want to buy the tools to pick these types of locks. I have to know as much as I can before I buy anything though
