Anyone Familiar with this Type of Locks? (Argentineans)

I have been trying to find the English translation of those locks and deadbolts but I just can't find any analogous product in Europe and in the US.

There is one very interesting that caught my attention, it is the one that it is called "llaves computadas/computarizadas" (Something like "computerized keys" or it could be coded keys) Which have little holes of different diameters one the sides of the key.

Anyone familiar with them?
These are the most common locks and deadbolts used in Argentina, I thought that those were Europeans but I couldn't find anything similar to the ones used in Argentina.

The first link (5150.jpg) is a double-bited lever lock. (That's the term, right? For having two profiles?)
The second lock is known as a dimple lock, where the pins in the lock work the same as in a more conventional pin tumbler but the cuts that lift them to the correct levels are drilled dimples in the flat of the key rather than a cut profile on the edge.

I'm not sure about what did double-bitting exactly mean, but the keys in the picture are one side works only", as the other side bitting is just a mirror image. This is so that the same key works from the inside and outside if need to be.

Dimple lock, where the pins in the lock work the same as in a more conventional pin tumbler but the cuts that lift them to the correct levels are drilled dimples in the flat of the key rather than a cut profile on the edge.

So the same principles of the common pin tumbler are applied on those for picking?
It it heavily marketed as a very secure lock, and very recommended by all locksmiths...

I had been wondering how to lockpick those two for a long time...

The first, like Gordon says, is a double-bitted key lever lock. I usually call them Italian lever locks. They can also be called vertical lift lever locks with double bitted key. Often they have a constant width across the cuts. The other one, again as others have said, is a dimple key lock or multiple inline pin tumbler lock. We don't discuss picking either of these locks in the open forum.

There's some stuff on both of these in my book (link to image below).

Why is the reason that those are not discussed in the open forum?
Too hard to understand or too easy to be known by the mass?...

restricted high security information

wow, that secure are those considered?
those are the "by default" locks installed in Argentina... I thought that the locksmiths were bullshitting me..

Mul-T-Locks (I'm guessing) are marketed as high-security and used in HS applications so you'll have to wait for Advanced access for details on picking them. Abloy Disc locks are very common in Sweden but they're HS too, so they aren't for public discussion.
At least some dimple locks are picked using exactly the same principles as the other kind of pin tumbler. Other models have security features that require special techniques and tools.
Go ahead and buy one and take it apart, see what's in there. If you can imagine any tools that would make picking it easier, try to make them.

A little offtopic but...

Abloy Disc locks are very common in Sweden but they're HS too, so they aren't for public discussion.

In Sweden they use ASSA, it is in here Finland that uses Abloy (only)

There is information on this forum about double-bitted key lever locks, not all of it is in the advanced forums. You may have trouble finding it until the search function is fixed. There are a number of security problems with the double-bitted key lever locks, but picking is not really a problem as it is too inefficient. The problems are more to do with forced access, so you have to think about how to protect against this, eg by putting guard plates around the keyhole. A good brand is always harder to force than a bad one, so make sure the steel is thick!
