your video was great. but master keyed system is not safe because you can decode your lock and make a master key from it and get in to other locks. they need to use high security locks for master keying. so it,s hard to get keys for them. assa abloy is a good one not Schlage or Kwikset or any pin tumbler lock.....
Very good explanation. I understood it completely. I just tried to re-key my lock. Oops, I just tried it and ran into a snag. I wanted to make my existing house key (27232) the master so I can give someone a key to my barn (23344). I found that the second position wants me to put a 7 bottom pin with a 4 master wafer on top. I found that the total cannot exceed 10! Is there something I could do to make this work?
At the very least a proper TPP master key system would hsve a master pin in every chamber. RC (rotating constants) master keying would be better for a very simple system.😮
Two chambers is the minimum IMO. Three if you have a GGM system. But four out of five on a 5 pin chews up a lot of the key space. It also leaves many keys working in this lock when you only need two. This is why you do 6 pin, gives you more key space. This video is a nice example for which pins to choose when mastering, but in practice not a sound system design. @@LockpickingLoser
@ponderinggeek7861, nowhere in the video does he say how big the system is, just that it was generated by a computer. This is just an example of how master keying works.
His stamping gives a hint at how big the system is. A1 rather than AA1. I know he said a computer did that. But to me it looks like he grabbed some setup keys he had laying around and he just mastered them. This is more an example of pinning than mastering. A video discussing how to plan a mastered system would be a good follow up to this. Even just the basics for a tiny system. @@LockpickingLoser
@@24hrMrLocksmith I had an interest in learning a new skill in locksmith for fun. I am very new and only just finished getting certified. I have been struggling with getting my practice locks to work after re-keying. I am following the rules I think are correct for Schlage locks. I am not beyond the MAC of 7 and doing even odd configuration. I think the issue I am running into is the top driver pin lengths. The master code I am using to learn with is 63472, and the key code 85694. Which should give me bottom pins 63472 and master pins 22222. But no matter what I have tried I cannot get the lock to function properly. So I am guessing my top driver pins are the issue. The ones installed currently are .160. I only recently found information and If I am reading the lab pin kit specs correctly I should be using for pins 0-3 a .235 top pin, 4-6 a .200 top pin, and 7-9 a .165 top pin? Or am I missing or doing something just wrong?
Fantastic video, this is a great refresher as well for pinning Schlage locks.
Just getting into the hobby. Your videos are really good.
I agree, Tri-Flow is awesome. It's what BEST recommends.
Never figured out about master key. This is a wealth of information. Thank you!
I love it! Barely getting into these kind of cylinders. Great video!

If it is a Schalge/ Weiser, etc you can’t have “1” master / top pins.
There is no #1 master pin on Schlages. Even if you got one that size it would seize up in a couple of weeks of normal use, trust me I've tried 🙁

Depends on the master key system you are designing and building.
What do you do with the old pins?
Recycling bin :-)
Locks😊
Schlage = Sounds Like : Sh Leg
Good video. But why master 4 chambers out of 5? There are 16 keys that will work in this lock now. 14 more than the intended AMK and A1...
It depends on how large of a system you need. If you only master key one chamber at a time, then it limits the size of your system.
Two chambers is the minimum IMO. Three if you have a GGM system. But four out of five on a 5 pin chews up a lot of the key space. It also leaves many keys working in this lock when you only need two.

When you place the top pins. How do you determin what size of top pins to use???
Usually, the Lab Pin kit has the specs.
Video soon showing MACS.
