  • by

Here, will show you the tool, its components and video instructions how to open and decode any VAG 2 generation vehicle lock. We will explain the best practices with which you will be able to use the capabilities of this unlocking tool to offer your clients a quality locksmith service. This Turbo decoder tutorial is for original products ONLY and we are not responsible for any losses or damages caused by the use of non-original decoders.

It can open door and trunk second generation locks. They started to mount this version of the lock in 2005 and kept using it till 2017 when a new lock came – 168 T profile:

Let us explain the difference between the two lock generations.

In the 1. generation locks the arrangement of the plates is one left, one right and so on.

In the 2 generation locks the plates are two on the left, two on the right and so on.

The profile of the lock remains HU66 for both generations. This is a little confusing but it’s a fact.

The HUF automotive lock manufacturer has incorporated several basic safety mechanisms that have increased the security level of the locks. Let me introduce you to these novelties. First of all, there is an advanced scroll clutch, thanks to which the locks are very sensitive to any rotational stress caused by anything other than the original key.
In addition, this clutch is further divided into 2 parts – front and rear. The front does not allow the application of rotational tension through traditional unlocking pick tools. The second part does not allow the use of selected or imitation keys as well as different power tools. There is also a third protection system – special anti-pick false cuts of the wafers and the stationary part of the lock. This makes the manipulation difficult and in order to unlock successfully a serious practical training is necessary. And so, we can offer you an adequate solution for opening those locks with Turbo decoder HU66 2. We just followed the layout of the lock wafers/ discs or plates / by placing double sliding pins on a common base. Now opening, decoding and locksmith service is not a problem with our device.

In order to understand the locks generation and their orientation please use our VAG tester key. It comes with your Turbo decoder HU66 2.

How does it work?

Insert the tester key into the VAG lock. Look at the metal part stop point. If the key stops with the red point touching the face of the lock – you have to deal with a 1st generation lock. If it stop with the GREEN point – the lock is 2nd generation. If both dots are away from the lock face  – no information. In this case extract the tester, reverse it and insert again. Now you will find the lock generation.

On your Turbo decoder HU66 2 we have engraved two orientation points on the Pin bar activator wheel or middle wheel. You will find these signs where it is written “orientation”. Use the orientation points to orientate the tool when you insert it into the lock and ensure that its direction / left or right / matches the points of the plastic head of your tester key. This info from the tester key must be taken at the moment when your GREEN metal stop point touches the face of the lock.

Opening procedure:

Once you have established the correct orientation of the lock, insert the tool to the end of the lock. Prior to the insertion, make sure that the turbo wheel has been in the extreme right rotation and that the pin activator wheel is in the extreme forward position!

Once reaching the end of the insertion, pull the pin activator wheel back to the rear. You will see “stop points”. Apply the rotational tension to the right on the front TENSION wheel, hold the tension, and turn the rear TURBO  wheel until its indicator line indicates the sector number 1 engraved on the pin activator wheel. Immediately afterwards, turn the turbo wheel to the extreme right position and only then release the front wheel rotating tension.


repeat all the same but change the tension wheel direction – use now left tension.

The good practice is to make about 20 “pumps” at point 1 stop sector. If the lock is not opened just increase the stop sector to 2. Stay there for 20 more pumps, if it is still locked – go to the third stop point. 20 times on 3 and if there is no result make 10 – 15 stops at sector 4 . Somewhere the unlock will happen..

Now, if the goal is to unlock – you have done it! If you have to decode the lock please do not remove the turbodecoder! TO GET ONE CLEAR LOCK COMBINATION PLEASE DO THE FOLLOWING STEPS:

Turn the tool in any direction – no matter locking or unlocking position, keep it turned and make one final pump with the turbo wheel and line it to point to stop sector 4!

Juggle the tool while it is turned . To juggle please follow the plane of the key blade! By doing this all codes will impress the pins in a good clear code position!

Then extract the tool ! Please extract it correctly:

rotate the tool in neutral lock position , turn the turbo wheel all the way to the right, push forward the pin activator wheel and only then you can extract the turbodecoder from the lock. 

To read the code:

pull back the pin activator wheel , rotate the turbo wheel all to the left – line to 4th stop sector and then look at the pins in the order shown on the pictures below: help yourself by using the code reference lines visible along the key blade! Remember – 1st line is indicator for code 2, second line gives you code 3 and 3rd one is for depth of code 4.
