Disassembling Protecto Lock

[jimboh]

Hi, I'm a n00b at lock picking, and I wanted to start out practicing with one or two pins. The problem is that the only lock I have at the moment is a Protecto brand key-in-knob lock. I searched the forums, and the closest match I found was this guide to take apart a weiser lock:

I tried it, but no cigar

So I'm wondering if anyone can help me here...
Here's a crappy drawing of the back side:


Hope thats enough information...

that's actually a quite good drawing...

I'm just taking a wild guess, and saying that those pieces of metal coming out of the 'plate' need to be pushed back through the hole.

From what I can tell from your pictures, the way to remove the knob is to turn the key and then push in the retaining clip through the hole in the collar.

Here is a post by Fixer from a thread I created. I needed to retrieve a broken key, and the easiest way was to take of the knob. What you need to do:
1)find a hole in the collar, if there isn't one, disreguard this whole guide.
2)You'll need to insert the key, and turn the knob while pressing in that hole with an awl (or other pointed tool that'll fit in the hole) and at the same time you'll need to try to pull off the knob. If it still isn't working, turn the knob back and forth slowly while pressing the awl in and trying to pull off the knob.
3) Once the knob is off, there should be a place for the cylinder to slide out of the knob, if not, you'll need to take a pliers and pull off the piece that is blocking the cylinder from coming out.
4) After the cylinder is out, you'll either need a plug follower, or you'll need to take the top cover off that is holding the springs in.

If you aren't exactly sure what I'm saying, or need some points clarified, just ask, and I'll be happy to take some pictures and put up an instruciton guide.

It's the same basic sort of lock you nuggett. Remove the clips in the back, pick the lock and turn it, push the core out with a dowl to keep the drivers and springs out of your eyeballs, then alter the plug as you see fit then replace after removing the blank drivers.

It is a good drawing. And yes, they do. Once the pieces of metal are pushed back so that the plate can come off, it's just a matter of taking of the parts underneath to get to the cylinder. I would suggest one of two things:

1. Make sure you pay particular attention to the order and placement of the parts underneath, so that you put it all back together properly (especially the spring catch that turns the knob).

2. Forget the whole KIK thing and just use the cylinder.

thanks for the reply everyone, and thanks for the compliments on the drawing

Well, I forced the clips through the holes and pushed the plate out of the way - including the spring and such, but the knob still won't come off.

It seems that the collar is part of the locking mechanism for the knob.

I tried n2oah's guide - and there's a hole in the collar, but I don't see anything that looks like I can push on. But when I turn it a bit, the hole exposes some metallic portions of the lock...

Thanks everyone again for helping this n00b!

Those are indeed excellent drawings...well done.

One idea which could be of much more help, would be some pics taken with a camera, from a few different angles.

Try examining the knob more closely: look where the knob slims down from the part you hold, to where it enters the escutcheon (the part which is secured to the door)...is there a hole or a slot? Does there appear to be something behind the hole/slot? Do you have the key? If there is a hole/slot, try unlocking the cylinder and turn the knob whilst applying pressure to whatever is behind the hole/slot...if you feel something move, try pulling the knob away.

HTH.

All right, seriously. Are you a technical illustrator or something?

[n2oah]

Ah, finally, the guide. I might be wrong as I type it up as fast as I could

You'll need an something with a point, like an awl or a pen, and preferrably, a vise.

The spot for the clip sometimes is in different places, so don't get mad if you can't pull the knob off at first, you may need to play around with it for a bit.

Wow, cookie for n2oah, good job!

[n2oah]

Thanks. I also have the same guide on my website http://www.freewebs.com/ag3ntddr/howdoi.htm
