This will help pick the HU100 lock with Lishi HU100 Lishi 2in1 Pick / Decoder.
The HU100 lock is widely used across The GM , Opel , Vauxhall range of vehicles across the world . A version of this lock is now used on some BMW models from 2010 onwards , although not the same pick as a mirror image, reverse profile of the HU100 lock , with a much longer blade , the same picking process will apply to these new locks.
The pick is not of the standard lishi 2in1 pick decoder design , this pick like the Mercedes HU64 and Ford HU101 picks , has 2 x lifters instead of the 1 lifter. This pick has 1 lifter for the top row and one lifter for the bottom row of wafers in the lock , this is because the lock is an internal 2 track lock.
The Lishi pick is simple to use if a very light tension is used , a very light tension is crucial for this lock, following the correct picking sequence also greatly simplifies the picking of this lock , and the decode is extremely accurate.
As stated this lock is susceptible to following a set picking sequence , it is always best to try and set all of the odd numbered wafers first , positions , 1 , 3 , 5 and 7 , this wont always be possible , but on the whole it is.
Once positions 1 , 3 , 5 and 7 are set , a slight movement of the plug will be felt , this confirms to the user that these positions are set. In the rare occasions that you cant set these first , set as many of them as you can , then pick the binding wafer on the even numbered positions , then return to the odds till set.
Once the odd positions are set , pick the even positions and the lock will open , maintaining a very light tension throughout.
Occasionally you will experience a wafer that binds excessively, when this is the case , it is necessary to follow a process , you must position your lifting lever on the heavily binding wafer, and apply a lifting pressure, then back off the already light tension a fraction at a time until the wafer lifts, as soon as the wafer begins to lift , reapply your full light tension. If every wafer is excessively binding very heavily, this is an indication that your tension is far to heavy, and needs reducing , once you crack the required very light tension, this lock is a straight forward , quick and simple pick.
The picking process
Insert the lishi pick into the lock , you will notice the top lifter lifts the odd numbers and the bottom lifter lifts the even numbers ;
Once the pick is inserted , with no tension applied , check each position to ensure that a wafer can be felt in each position , if so , you need to apply an extremely light tension , you are then ready to pick the lock , we use the top lifter to try and set positions 1,3,5 and 7 , starting with the pointer on the No 1 line, lift the lifting lever 1mm , if it moves leave it alone, check the next odd numbered position and so on until the binding/resisting wafer is found.
Once the binding wafer is found , lift it 1mm , if still resisting then lift it another 1mm and so on, until it moves and has a tight slapping feeling and motion, this is then set, now move to the next binding odd position.
1st binding wafer to be picked is position 5 .
2nd binding wafer to be picked is position 7.
3rd to be picked is position 4
4th is position 6
It is worth noting that position 1 and 3 wasnt picked , yet a movement on the plug was felt, suggesting the top row is set, as these positions were not picked it would suggest that they are both No 4 cuts on the key, but a worn 3 cut can also not need picking.
Next is position 8 and the lock has opened.
As with the top row , position 2 did not need to be picked, thus signifies this too is a cut No 4 on the key in this position, but remembering a worn 3 cut can also not require picking. With the lock now picked you need to hold it in the open position via the tension handle in order to decode the lock.
