Lishi tools 2 in 1 user guide for those keen to learn about the genuine Lishi BMW HU58 2 in 1 picking & over-lifting technique.
With Lishi HU58 2 in 1 lock pick and decoder when you pick the lock , the lock will turn slightly then you can decode the lock, but if you want to just open lock without decoding then pull out 2in1 a little and the lock will turn, if you don’t pull the tool slightly out then lock will not turn, they could not put the cut out on the tool as it is on the key as this would weaken the tool
An overlifter is a key blank cut with a No1 cut in each position yes then you must cut down the shoulders to allow room for complete key and tension wrench in the lock.
when you have made your overlifter key
1) insert tension wrench
2) insert your overlifter key fully so all wafers are lifted
3) apply tension to the tension wrench
4) remove the overlifter key maintaining the turning tension
5) this will hold all wafers in the No 1 height position
6) gently feather your tension removing a tiny bit of tension at a time.
7) you will hear little clicks as wafers fall in turn
once tension is fully removed if lock isnt open then start again
The knack is the feathering of the tension , let too much tension off in 1 go and too many wafers will drop , let too little off it takes longer , its just practice to get this rght.
Remember when picking the HU58 , the plug will turn 10 degrees once picked and stop , you then need to withdraw pick about 1/2 cm to a little arrow by the Lishi logo, once in line with arrow the plug will fully rotate and open.
There are 3 versions of this lock i’ve seen to date , some have wafers missing in some positions , some have all wafers and some have blocked No 9 position .
As has been said overlifting is a much quicker opening on these using a key cut to a No 1 height and the shoulders cut back , a good tension wrench and a little practice on correct feather tension yeilds instant results , same with mercedes HU64 overlift a dream.
Remember with BMW boots these pick anti clockwise to open , if you pick clockwise which is easier , hold the plug half way between verticle and horizontal then spin anti clockwise , as if you fully turn from vertical to horizontal you will apply the deadlock.
if the BMW plug on boot is vertical its not deadlocked and will open on central locking or will need picking anti clockwise once , if the plug is horizontal then its deadlocked and needs picking twice or spinning when half way between horizontal and vertical.
Here, attach some photos of how to use LISHI Lock Pick (HU58) for old BMW
Works perfect! All done with LISHI HU58 2-in-1 and LISHI HU58 Blade for BMW
Hope this helps.
