Introduction to Lever Locks - Types and Terms: Ultimate Picking Guide Part 1

hello again it's Locke noob and this is the first of a five part series on lever locks and leave a lock-picking and a thought for the first part I would start right at the beginning which is what types of leave a lot are there out there how do they work and what's although weird terminology we use on talking about lever locks and their keys my reasoning being is that once we understand what leave locks are and how they work it makes the videos later on which are how to pick them a whole lot easier to understand it also means that we'll hopefully use the right words for the right blocks so where do we start well it's quite a range of locks here but I think the first lot to start on is this one here this may look like an old rusty lock and well that's because it is an old and rusty lock but it's also in its own way quite beautiful you can see it's been handmade and we turn it around you can see that all the mechanism is there for you absolutely beautiful and inside we see where the magic happens there we go so this is an example of a warded lock but it still has a lever in it look at the key that comes with this isn't that absolutely beautiful a beautiful beautiful beautiful old key and if you look at the tip of this key you can see that we have specific shapes cut out and those shapes aligned with the warding on the inside of the lock and see this is a diamond and bar warding so you have the diamonds there and the bar at the bottom and this key does two things once it's clear the warding it'll do two things there we go so first of all it will lift the lever out of the way which is sprung from the top and the tip of the key will engage with the Talon in the bolt and slide the mechanism across and of course in Reverse it'll pick up the Talon lift up that lever and there you go you'll see that that will still lock itself down isn't that beautiful and warded locks were on the first type of lock in existence going back to ancient China in ancient Rome so the next lock you want to look at in detail is a rim latch lock here is one and these have been around for a few hundred years and they do look like a lever lock and in a way I suppose they still are some are more complicated than others and the older they are usually the better Bilbo are and the more complicated than mechanism inside but you can still buy these this is absolutely brand new and they're usually marketed for locking up sheds and the like although a lot of manufacturers say that they shouldn't be used unless in conjunction with another lock so let's turn let's turn this over and I'll show you how this works so there we go and just gotta be careful not to not to let that spring fly out but you'll see that the key comes up pushes on the lever grabs the bolt talent and pushes the bolt out I can actually insert the key upside down on the other side because the two levers are sprung together even though they pivot separately so again I can push down the bottom lever although this one only serves to move the top lever to allow this little bolt stump to clear this is really this type of lock this rim latch is really about as basic as a lever lock mechanism you can get it's got a working lever and the key can work outside town either way up inside the lock to make this work so this is really really simple but we're not going to focus on this because realistically this is the lowest security lock of this type you can get and it's not one which will be really picking before we move on to the modern locks which we will learn how to pick I think it's best that we actually start to look at some terminology let's have a look at some keys so in front of us is a blank lever lock key just so we don't worry too much about what's going on with the key guess the main part so first of all we have the bow this is of course the bit that you grab hold of when you want to turn the key then we have the shank then we have the collar and the collar acts most often as a stop so that key isn't inserted too far into the lock then you have the throating which is normally the distance which is the thickness of the lock casing itself then you have the bit the top is called the nose and the bit the bit is attached to is called the pin now let's look at a cut key and you'll see that there are some new features one of which is the bolt step which is in a lot of leave locks the parts of the end of the key which throws the bolts although it can sometimes be in the middle of the key then you have the lever steps and actually the way that this key is cut it really does look like steps how deep those steps are cut I'll call the interval so there are different intervals for different level ox depending on what their individual cuts depths are this key is actually a pipe key and pipe keys are called such because of course they have a similarity to a pipe then always hollow all the way down but you can make keys using hollow pipe like that now here are two keys with a couple of other little features which you do see and that are warts normally they're just like a the warded lock look that earlier to allow the key to pass through the warding on the inside of a lock and then you have the collar Ward which often does the same thing so let's look at the first type of lock which is still around used loads and loads and loads still inside plenty of buildings at least in the UK and this is a non curtain lever lock it works with a key and I can insert from the back so you see what's happening there we go you can see the steps on the key there including a bolt step and what happens is that those lever steps engage with levers and they lift them to the correct height the bolt step will grab the Talon and if all the levers are lifted to the correct height the bolt stump will be able to clear the gate and open up in Reverse does the same the key listen II was to the correct height allows the bolts thump to travel through and the key can pull or push if you will the bolt back to the closed position so let's have a look at the parts of this locking a little bit more detail there so what you can see is the lever pack and in the lever pack you have a number of levers those levers have a lever spring which forces the levers down inside the lock you can see the bolt and the bolt has a bolt stump the bolt stump cannot pass through the gating of that lever pack until every single one of those levers are lifted to the correct height allowing the gating to align with the bolt stump the key can then engage with the Talon which is a V like not in the bolt itself and it can pull that bolt back and forth as long as the bolt stump is free to move inside that gating now what I really like is that the spaces either side of that gating are called pockets isn't that cool so you have pockets either side of the gating and what makes the gating are the lever bars so we call them gates but you have a bar at the top on this one and a bar at the bottom with a gating in the middle the big clump which actually engages with the other side of the door to lock it is of course called the bolt head then he have the pivot which is where the lever eyes engage with and you even have what we call the lank hit hole isn't that the Lanka toll which is really what engages with guides to allow that bolt to slide correctly to the left and to the right now what we have here before we move on to curtain'd the verlox is a lever padlock and there's the inside of one and I won't spend an awful lot of time talking about this but it is worth talking about one of the features inside this because they are by and large exactly the same as nearly every other non curtain gleave lock in the way they are built and the way they work that one thing which this particular lock has is a drill pin this little up post inside the lock and that is a way to guide a pipe key onto the drill pin to Center it which allows a key properly so that they can work but again I won't talk about this too much because it's just a lever pack with levers and lifted to the right height to allow the vault stump to move through the gating the last type of lock I think we should mention is the higher security cousin of the non that curtain leave lock the curtain lever lock you can see it has many many many features which are similar and indeed it operates in a very similar way I'll put the key in through the back turn the key we lift the lever pack allow the bolt stump to align with the gating the key pulls not on a talent at this point but the curtain itself engages with the bolt a bit like a camp and pulls it across there we go and back again if we want it to sort of difference between the curtain'd and the non curtain version of these leave locks well the difference is in the name really the this lock here is a curtain Eve lock has a curtain and that's this whole mechanism on the inside and this acts as a sort of shroud for the inside of the key and makes picking it with traditional wire tools a lot more difficult in fact it's not the key in this case which necessarily acts on the bolt itself but it's the curtain acting like a cam which engages with the bolts and retracts it across as long as the key itself has lifted the lever to the right height you'll also notice that this block actually has false notches so it's got some fake notches which act a bit like the gating and can engage with the bolt stump and trap it if the levers are not lifted to the correct height the other feature of this particular lock is that the belly of the lever are so low that they are even touching the curtain which makes putting a lever wire a lever pick in underneath it extremely difficult so there we are hopefully now we know a little bit more about the terminology and types for lever locks and in my upcoming videos in this series we'll be talking about picking techniques for the non curtain leave locks the lever padlocks the curtain lever locks and then some advanced picking skills as well okay thank you for watching and I'll see you for the next part bye
