Welcome back to the guided series for picking and decoding the BMW HU92 Ignition using the Genuine Lishi pick and decoder Vol.2.
As mentioned, the process of picking the lock is the same, the only difference is that the single lift tool uses the same pick arm to pick both tracks. The twin lift tool uses a different arm for each track, and other than this, the process is the same.
As with all Lishi tools, we must first centre the lifting arm(s) and fully insert the tool into the lock. We can confirm full insertion by ensuring a wafer and a spring is felt on positions one and eight- if a spring and wafer is felt on both position lines, we have full and correct insertion.
Once fully inserted, we apply a medium to heavy tension to the tension arm in the opening direction (I start with a medium tension but part way through it is often necessary to increase this a few times until heavy to get binding wafers). We then check each number4ed position by gently tickling each position in turn. If the wafer moves, we leave it alone- we are only interested in solid binding wafers. Each time we find a solid binding wafer, we pick it until movement is felt again, this is normally a tight slapping bounce on the spring. Once each binding wafer is found, the lock will open.
It is always easier to pick HU92 locks locked rather than open, it can still be decoded in the locked position to generate a key. So, with our tool correctly and fully inserted, I apply a medium tension to start and navigate the wafers to find the binding positions and pick as follows:
Position three is the first to bind and pick.
Position one is the next to bind and pick.
Position five is the next to bind and pick.
Position six is the next to bind and pick.
At this point it all seems to have movement, so I increase tension to medium-strong tension.
Position seven is the next to bind and pick.
Position eight is the next to bind and pick.
Position two is the next to bind and pick.
Again, all seem to have movement, so I increase tension to strong-heavy tension to encourage binding.
Position four now binds solid and picks.
Position two binds and picks again, and the lock opens.
What is significant here is that we have had to pick all eight positions in the lock which already tells us the lock has nVisito positions with the deepest number four cut, so there’s no four cuts on this key.
It is common to have to repack high lift positions two or more times especially in locks with multiple high lifts in them sat next to each other. The more high lifts in the lock, the stronger the tension needs to be. More adjoining high lifts also impacts on this need for strong tension.
So, with our lock picked, we can now hold it in the picked open position ready to decode the lock.
