Picking The HU64 Mercedes Lock
using the Lishi 2in1 Pick/Decoder
The Mercedes HU64 lock is a
straightforward pick and decode
process using the Lishi 2in1 tool, door
locks being far simpler to defeat than
boot locks.
The lock is a 10 wafer lock with 5 cut
heights referred to as heights 1 to 5, 1
being the highest lift and 5 being the
lowest lift, all 10 cuts are found in the
door lock and in the boot lock.
Picking the HU64 lock
Fully insert the tool into the lock, apply
a light tension and move one of the lifters
to the first wafer gently lift the wafer half
a mm if it moves then leave it alone and
move on, try the next, any movement in
the wafer at all, then leave it alone. When
you find a binding wafer, lift until it has
free movement again, a tight bounce I
refer to as slapping. Every time you find a
binding wafer, pick it until it slaps. Once
all binding wafers are set, the lock will
open.
Position 5 is the next to bind and pick
‘Pick it until it slaps’
It is not unusual for a set wafer to drop
out during the pick process , so expect to
find a previously set wafer to bind again
even after picking already.
You will notice that the tool has the
10 wafer positions, in 2 rows of 5, an
upper row and a lower row and follows a
traditional 1 up and 1 down format. the
grid to the right is the cut heights which
will be obvious in the decode section of
this guide.
‘There are no proven
picking sequences with
this lock at present, so it
is a matter of finding the
binding wafer and picking
it until bouncing tightly’
There are no proven picking sequences
with this lock at present, so it is a matter
of finding the binding wafer and picking it
until bouncing tightly, until all wafers are
picked and the lock opens.
The HU64 lock picks easiest in the
locking direction and is a double lifter
design of tool, and requires the lightest of
tension for consistent success.
Excessive tension and overlifting is the
most common cause of failure with this
lock; the more tension that is applied the
higher the likelihood of overlifting and the
more likelihood of damage to your tool, so
very light tension is required for this tool.
