Here is a picture of the lock itself. Notice the 'CAUTION DO NOT OPEN CASE' sticker. This is because when opened the parts will spring out and you wont know how it all goes together again!
This is the inside of the lock mechanism with me holding the parts together, and also the back case which contains some warding so the incorrect key will not work.
The next picture shows the key in place and turning. The key has engaged the bolt and also lifted the locking bar. This bar is in place so you can't just slide the bolt in and out with wire. The locking bar can also be engaged from the bottom keyway and the mechanism will lift the top bar unlocking the bolt. The key would also be against the warding on the back of the case, but as the lock is open you can't see it.
Now to show the warding on the back case to stop the incorrect key
Now we will look at putting the lock together if you have opened it and had the parts fly over the room!
Component parts
Bolt goes in first
Followed by the 2 locking bars, joining in the middle
Now the handle mechanism
And finally the spring that makes the lot work. This connects onto the lip on the locking bar and a lip on the handle mechanism. Once the spring is on you will need to hold the parts in place as shown. Then have some fun putting the cover back on! You can put your little finger through the hole in the back of the case and hold the mechanism while replacing the screws.
That’s it! I have let the pictures do a lot of the talking, it’s quite a simple lock so should be easy to see how it works.
You can make up a bypass key that will open most of these cheaper locks as below.

(MOD's if this key is to far please delete photo - but as its such a low security lock I have included it)
