WD-40? Yes, it is important
Always apply WD40 before inserting the decoders in the locks. WD-40 loosens rust-to-metal bonds and frees stuck, frozen or rusted metal parts. With WD-40 you help the pins move inside the lock cylinder - this leads to better performance.

Step 4. Prodecoder HU84 Opening procedure
Make sure you have inserted the tool on the correct side
The most important part is how strong your tension is (on the tension wheel). If its too weak – the lock won’t open or it will open very slow. If the tension is too strong – you may break the tool or risk of tool deformation.
Turn the tension wheel to the LEFT (keep holding it) and then turn the turbo wheel to the left until you reach the 1st stop point (we have 1 2 3 stop points engraved on the the gate) and return the turbo wheel to the right in its original position.
Turn the tension wheel to the RIGHT (keep holding it) and then turn the turbo wheel to the left until you reach the 1st stop point (we have 1 2 3 stop points engraved on the the gate) and return the turbo wheel to the right in its original position
Repeat this procedure 15-50 times on stop point 1, 15-20 on stop point 2 and 15-20 times of stop point 3 . This is what we call “progressive opening”. Do not rush the tool, the point here is not to reach point 3.
When the prodecoder is turned to the opening position, stay in this position and turn the turbo wheel to the stop point on the gate wheel (the opening point)
