Atra Dierre Prima Decoder - Chiave Bulgara
Atra Dierre Prima Chiave Bulgara is a professional locksmith decoder. And we made it specially for Atra Dierre Double Bit Lock System. This manual self impressioning lock picking tool works fast and with no damage on the lock. With Atra Dierre Prima Decoder you can read the code.
With this Double Bit Locks decoder we offer two decoding keys (Soft keys with Pins) and tension tool. We have made this kit with two keys because it is much faster, especially if the lock has 4 turns as it is the case with Atra Dierre locks. You use the first Soft key for the first turn. Then you use the second Soft key for the second turn. From this point you already have the now ready decoding keys for the 3rd and the 4rth turns of the lock. Hence, you fully unlock the lock much faster.
Another key point is how easy you can repair any broken or twisted pin – just unscrew the bottom bolt of the Atra Dierre Prima and change the damaged pin.
After we ship it, the decoder is ready for work. Because of that, you don’t need to further arrange the pins in specific order. So, all you must do is to control the traction of the pins with the bottom screw on the soft keys.
Principle of Opening with Prima Decoder
This entire process is very easy – you insert the Tension tool that puts the lock carriage (lock tongue) in tension. This is the same function as the key normally does when it is turned. After that the first soft key with the pins is inserted. Its important to emphasize that this soft key has the exact geometry and size of the original key of Atra Dierre 6×6. Moreover those teeth (pins) have the possibility to move.
In brief by slightly shaking both the Tension and the Stick with pins the vibrations move the pins of the soft key with pins . This happens until it “assumes” the position corresponding to that of the “teeth” of the original key. In this way the profile of a half of the key is obtained. To obtain the other half, it is necessary to repeat the operation for the second half of the profile with the second soft key. At this point you have a complete double bit profile able to open and close the lock exactly like the original key of Atra Dierre.
