Check by push the turbo wheel forward. If nothing moove – that is – tool is correctly orientated

Before to proceed to with the opening please clean the lock with WD40 or something similar! That is ipmportant to ensure the free movement of the code wafers / discks / . The turbo tool doesnt work when some wafer is blocked or not freely move.

To unsert the tool into the lock turn the turbo wheel all the way to the right, push the pin bar activator wheel all to the front. Get the tool on the ring of that pin bar activator wheel and insert the key blade. Be gentle and avoid forcing it . If the lock is in a good mechanical status the key blade must slight in pretty easy.

Lock Decoding procedure

When the lock is opened with the Turbodecoder we can proceed with code reading. Te code can be readed for one reason – if we wish to cut a mechanical key. The cutting procedure can be made with CNC locksmith cutting machine. Any key has a numerical code and when that code is inserted into the key cutting machine it can cut it on a key blank. This turbodecoder can give you the code necessary for reproduce a working mechanical key.

How it work:

after the opening if the loksmith want to read the code he must to do few additional steps. Lets start from the opening. The tool is in the lock and it turn it from left to right. To get a good and clear code the operator must turn the lock in some fo the directions – left or right but NOT in neutral lock position.

Let it be left turn direction. Keep the tool to turned to the left, do one final pump on the turbo wheel till it line come to stop point 4. now shake the tool by follow the plane of the key blade. With that shaking the wafers impress the sliding pins on the turbodecoder. They transfer one precise altitude to the pins and that altitude is more easy to read after. After you finish with that go on neutral lock position and follow the extraction procedure.

When the tool is out of the lock pull back the pin activator wheel then rotate the turbo wheel to the stop position number 4 . Do not rotate it back , just start the pin altitude reading. Its good to refer the top pin surfice to the reference line wich is along the key blase.

 First line corresponds to cut / code / 2. Second line is the measure of cut / code 3 / and third line show you the cut or code 4 / depest code from the combination / 

 The lock has 7 code plates:

and each plate can have 4 heights. The code lock code is actually a line of 7 digits, with any number in the row being from 1 to 4.
An example code for some hu83 lock is 1123344


If the operator knows this code, it could cut a mechanical key to replace the lost original. One of the main advantages of Turbodecoder is that after successful unlocking of the lock, the operator can read the code from the tool itself!

Few advises about pin reset of the Turbodecoder:

  • use only original set up hu83 devices – they are made for precise reseting of your pins and if some other tools be used it is the risk of tool damages!

  • insert your reset tool as it is show here.
  • note that the pins slide pretty easy and if you apply any unusual force its can easy bend or broke your instrument!
