This lock is getting more and more trendy among aluminium sliding, usually for bigger house. It is stronger and seems more durable than common aluminium lock with square casing.
But in the end still depends on workmanship. If alignment and positioning is not right, even the best lock fails.
Can consider this type of lock for your sliding door (if not yet fabricated)

Model: Samsung P728 + Stealth Deadbolt
Functions:
Origin: South Korea + Taiwan
Brand: Royal President Guardian
Functions:
Origin: South Korea
Comments: Royal President specialises in electronic locks. Very reliable brand.
Extra Service (has to do them Free of Charge):
This door has a bigger hole than the deadbolt plate. If we just install like that, can see some small hole besides the deadbolt. Although small, still doesn’t look nice.
Hence something else is needed to cover the hole. There are alternatives like door strengthener, standard backplate which is square, but both doesn’t look nice (according to the customer).
So we need a custom made solution that will blend in with the lock, so that it looks “original”. We come up with a round, hairline and plasma cut stainless steel according to the fitting of the deadbolt design. The effect is very nice.
Locksmith always need some custom cut metal plates. Sometimes brass, aluminium or stainless steel. It is simply because there are too many design, situation, thickness, requirement, etc. In order to install the lock to work with durability, strength, and smooth, some degree of customisation is needed.
So do not be worried your locksmith used some extra plate on your door. If used correctly, it makes your lock and door stronger than before

This item is getting popular nowadays in Kuching. We have seen a lot in our client door (asking for repair)
It is marketed as an additional locks for a wooden door. Same functions as a surface mounted barrel/tower bolt below:
Yes same function as above, but concealed into the door, not on surface.
Under some circumstances, we might recommend this concealed barrel bolt, like special location, rarely opened door, etc.
However, as a standard guidelines, we say, avoid using this. Why? If you notice the top photo, there is a gear-shape key. There is also a gear inside the lock body. After repeated use, bolt-in, bolt-out (using the gear), what will happen to the gears? Both become rounded and later flatten. So you can’t bolt-out/ bolt-in anymore (actually can, if you use a sharp item and slowly hook the bolt in, but you will not want to do it everyday). No more gear teeth, so to speak. It might happen to the key, or to the gear inside the lock.
The problem lies in the material used. Those gears are usually made of Zinc Alloy, a relatively soft metal.
The photo that you saw on top, that bolt is sold by us, a highee quality type, full stainless steel lock body, yet the key is still Zinc Alloy. So it will last longer than those Zinc-body concealed bolt, but not too long. One day the key will still become flatten, although the gear inside the bolt part won’t.
We will continue to search for a manufacturer that produce full stainless steel bolt with stainless steel key. Stainless steel gear-key will last much longer, but we still need to test it first in order to not distribute a problematic items.
Meanwhile we will say, stay away from this concealed barrel bolt, unless under a rare circumstances that make it a no-choice.
Use those surface mounted type. Old fashioned, but time tested.

Type: Mortise with Handle
Origin: Samsung, South Korea
Unlocking method:
This door expands. It keeps on expanding so after a while, it is quite bad. So once you push it to close, it is hard to open. This customer ask someone from outside to help kick to door open. And the door cracks. (UPDATES: After checking on the client’s door, just the surface laminate layer crack actually, not the whole wood wall. Inside still solid)
Wooden door is quite hard to predict. Some expand, some shrink, some twist. And some happen to new door (can claim warranty), some happen after 1 year, some happen after 2 years, etc.
We are fully focused on locks, so door knowledge is somehow limited to experience only. From experience, we can guess what type of door will expand, what type of door shrinks, etc. But why? We can only guess, can’t be sure.
We have worked with some door seller. Some just sell. Some is a contractor carpenter. They are almost the same like us, they can explain what happen to the door but is a pure guess on experience.
But there are a few, who are really specialised door maker. He knows what’s wrong with the door once he sees and touches it. The differences with common carpenter is he can explain to us the technical and scientific reason behind it. Just like a teacher explaining in details.
So for door problem sometimes we need a skillful and experienced carpenter’s advise or if better a specialised door maker’s advise. We always keep their number with us. Called them up so often that we have become friends.
Here we list a common door-cannot-close problem:

Usually a sliding door, be it wooden or aluminium (steel sliding is rare), will need 4 items to work:
But there are some other alternatives like the above photo. The all-in-one sliding hook lockset.
There are many China brand, they break easily.
But there are also good one, although not easy to find. Still using Zinc Alloy material, but is thick and heavy, and good mortise mechanism.
If you have budget, however, should just stick with the 4-piece hook lock. Priced higher, but so long lasting and so reliable. Stronger, piece of mind, and made of stainless steel material.

I come across this catalogue from a fellow locksmith in KL. I have got my hand on many St Guchi product and am not impressed.
But this is a Molybdenum padlock…
Molybdenum is usually a premium padlock and among the best material for shackle. I ll try on a St Guchi Molybdenum padlock soon, but for now lets talk on some padlock’s shackle knowledge. Because everybody love padlock, except me (maybe)
So now you know the shackle and its material. Next time you can choose a padlock according to your needs.
Another important aspect is the internal material and the key cylinder. No matter how good the shackle is, if the key cylinder is really cheap, the padlock can be compromised in seconds and it defeats the purpose of the padlock. I ll let you know how to choose a good key cylinder in the future.
With Sincere.

We have seen Zinc Diecast as the most oftenly break. Followed by Zinc Alloy.
The above photo is a Zinc Diecast. It is installed at a Metal Door. Aged at 4 years.
We changed to a fully stainless steel handle for him. Definitely won’t break.
