Portuguese Lock - WOW [heavy image]

So,

I discovered recently Teicocil is a portuguese brand. It stands for TEIxeira, COsta & SILva, Ltd, the 3 owners.
It's a cheap brand, as their locks don't have that much quality. But it's portuguese, so as a patriot, I'm always looking for something to honor my "brothers in arms"!

I finally found it :mrgreen:

Here's the lock:
Image
It's a 10 pin dimple lock. 2 rows of 5 pins, one on top and other on bottom of the keyway.

The front side has only 4 pins, as it's the side of the lock that stays inside the house, hence no need for much security. When I picked that side, the plug started to rotate, but no operation of the bolt. That made me soo happy! First lock I saw with this system. So let's study it!

I found that I need a deeper wrench, because there are actually two moving parts in the plug. The plug itself, and at the back of it, there's the piece that operates the bolt. So in order to rotate it with the key, the plug needs to rotate too. So an unprepared attacker would use a small tention wrench and have no results.
But then I thought: "If I have a thin T shaped wire, I could operate the back piece directly and bypass the whole lock!".

So let's disassemble everything and look at it.

I was, oce again, surprised :mrgreen:
On the inside part, it's true that would work. But that's irrelevant because you would never have to pick your way into a house FROM THE INSIDE. So no lack of security here. But on the keyway on the other side (the one used to ENTER the house) the system is different. Here are pics:

It has this small post:
Image

With the key inserted it pops out:
Image

It then connects with the piece that operates the bolt directly:
Image

Which is in direct contact with that back piece on the other keyway. So they can rotate independantly if the key is only inserted on one side, blocking if both keys are in the lock:
Image
(Fun fact: this system reminds me of a lever lock bolt)

So, the small post. I started to disassemble it (front plate off):
Image
(This rounded piece is what connects the small post to the plug. So you cannot physicaly rotate it independantly. Ever. So it makes that bypass IMPOSSIBLE! SUCCESS!)

By removing it, the post is removed:
Image
(You can see the pins from the back of the lock now.)

Image
(The spring is to make it return to inside the lock and disconect from the bolt when the key is removed)

So in order to pick this lock, you would need a deep tension wrench to make that post stick out and connect with the bolt, or you would just rotate the plug and not open the lock.

There is a problem however. The post is directly behind the pins, so even with a deep wrench, it would not push it. You would need something wide enough to push it, but thin enough to not get in the way of your pick. Maybe a smal L shapped wrench that enters the keyway and fills the whole back of the lock, leaving you space to move your picks arround. Don't know if I was clear, but I'm sure you'll figure it out :mrgreen:

Besides the anti-pick features, the outer part of the lock (don't know it's name) can rotate freely. What makes it REALLY hard to grab and break it.

I have 3 points I'd like to stick out. It has no anti-drill protection, It has no security pins. It's poorly made, as there's one piece that has already a little bit of rust (the lock is brand new). But we can't be perfect. It's very cheap (a little over 30€) and for that price, it's the best lock I've seen brand new (remember, it's a full lock, not just a cylinder). So I now recomend this one to whoever wants something (a little bit) secure and really cheap. Of course it's not the best stuff, but the quality/price relation is unbeatable (at least here in Portgual).

So yes, I'm getting a little bit happier with portuguese brands. Maybe in 100 years we will compete with the old Mul-T-Lock locks :lol: :lol: :lol:


Hope you enjoy, I didn't know we had a brand that produced something like this!

Excellent post, fgarci03! The bolt does resemble a lever lock bolt.

Questions:

Were you saying that if someone leaves a key on the inside lock that the outside lock will not work? Or will the outside key push the inside key out of the lock enough to operate normally?

If the outside key can push the inside key, can you prevent that by having the inside key slightly turned, or does that open the possibility of bypass?

Keep those great posts coming! We love seeing how different locks work. :-)

Good question. I got up from bed to try it :mrgreen:


So. If you leave the key from the inside, you can insert a key (or a pick) from the outside and operate the lock (it will make the inside key rotate with your key).
If you slightly rotate the inside key, you can't even insert the key full way inside, because the piece where the small post connects in order to operate the bolt (4th image on the OP) will be misaligned, not allowing the post to fit it.

When that happens, this becomes a true pick-proof lock. not even drilling the pins would work. Only way in (besides kicking the door down) would be to pull the cylinder out and operate the bolt directly.


About the bypass. Which ever situation it's impossible to preform, unless you're on the inside of the house. The keyway that faces the outside has a piece that connects the post to the plug, making them impossible to rotate independantly (6th image).
I'm not sure I answered your question though...

Small edit.
There IS a way you could pick it.


Use a regular tension wrench to pick ONLY the plug, and not pushing the small post in. Then when it is picked, push it in with the wrench, rotating the plug slowly untill it's aligned with the bolt piece, thus connecting with it. Then it will operate the bolt, and rotate the key that is on the inside with it



P.S. - I'm calling the small piece that sticks out on the 3rd pic a post. Not sure if it's accurate though. Please correct me

Thanks for the breakdown and pics..but id like to had this point without being a smart arse which is valid, before anyone runs out to buy this lock.
The bypass may be alot easier than expected :shock: the two main parts look like there die cast..cam and fixing plate !

You look to be correct about the cast pieces. However, think fgarci03 is looking for non-destructive bypasses.

Yes, I was talking about NDE. But now that you mention it, being die cast, how would the bypass work?


An I really apreciate your input, never crossed my mind you being a smart arse :mrgreen:

Believe that the bypass he is referring to is using a torch to heat the lock enough to melt, or at least soften, the die-cast metal (Zamak or other such alloy). Also some low temp alloys can be too weak and will break or deform if forced. If I am missing a bypass about this lock with die-cast metal, let me know! I do have a lot to learn.

There are a number of locks that are in my collection that I would not use to secure belongings, but I do like the different ideas and varying technologies that allow them to work.

Most of us also know of a few 'secure' locks that are subject to easy bypasses. This lock is a low priced lock, and is not to be considered overly secure. But even Abus has the vulnerability that Dicey posted. Thank you for posting the weaknesses you see - that is what this site is about!

Gordon

P.S. If the fire is hot enough to melt the Zamak, doubt I would be able to put in a key and operate the lock, no matter how high quality the materials used to make the lock!

Haha the video is awesome.

That lock is like the Teicocil. It's portuguese, but made in china. I think all portuguese brands are too.

And yes I wouldn't rely on this lock to protect my belongings. I just found it was such a great improvement to regular stuff I see from them.
The idea is great. Now they just need to improve it. But of course, the price would rise!

I hadn't seen one of those. Interesting at any rate... thanks for sharing some pics.
