Is it possible to pick a Dudley by usineg the Serial Number?

[bond_guy]

I have a lock with a serial # GT 04250
Is it possible to use that to find the combo?

possibly thats a code number, if you had dudleys code book you could look your combination up, I don't know if the code book is publicly available, and by that i mean for sale to locksmiths.

I am not sure about Dudley's policy... but with a Master lock, you can fill out a lost combination form, photocopy the lock it to show that it isn't securing anything, get it notarized and mail it off to them...

...and they'll tell you the combination.

I've been unable to find the same type of info for Dudley. If someone knows Dudley to provide this service... please post the details!!

To my knowledge... There is no mathematical relationship between the lock's serial number and the combination and efforts to collect large numbers of serials and combos did not ever net the ability to work out any sequence that comprised unlisted locks by serial number.

Howdy, I'm the Dudley man. Unfortunatly, no matter how hard you try, you cannot pick Dudley locks. You can, however, manipulate them with the disks, or attempt to decode them with the sticking points or the serial number. While I doubt that the serial number can do anything, if you can give us your sticking points in my thread, I will attempt to crack them and make some possible combinations for you.

Easiest way to get into a Dudley is with shims.

If you want to reuse the lock, drill a small hole directly above the dl in Dudley stick a pin in the hole and turn the dial until is stops. Turn in the other direction till it stops, then back in the original direction again. The pin will align all three wafers into their open position.

Congratulations, your in.

Cool trick silver, what's your backround?

We try not to get into destructive entry here, it gives our critics more ammunition.

Welcome to the forums.

Not sure I'd want to reuse a lock with a hole in it

Thanks for the welcome SFGOON.

I was taught how to pick locks at the age of nine by my father. Researched and practiced ever since then.

Made my first set of home made tools at 12 (as I kept breaking the factory ones that belonged to my father) and made my first tubular pick at age 17 (6 pin internal type for Supra locks)

Made a complete set of tubular picks at 19, and I still use them to this day.

Have a locksmith business license as a side job.

First off, you can't shim dudleys, they use a different laching mechinism, you would simply ruin the shim by attempting. I made a cut away, and am looking at it right now. No way you can shim it with conventional shims. As for hole drilling, these dudleys ahve like 5mm of metal to get through from the back. The only way I see drilling happening is from the front, and face it, who wants to use a lock that you drilled to find the combination? As far as I'm concerned, thats a way to open it if you just want in, but if you're going to do that, why not use bolt cutters? I figure spend more time on manipulation of these magical things.

There is no problem drilling through the back of the Dudley. Use the right bit. But, if you're gonna go to the trouble of wrecking the lock, you might as well just smack it open with a hammer and be done with it.

Thanks for all the hints.
I'll have to get the sticking points later.
