Operating instructions
for double-bit high-security locks
S2700U and S4700U
A) Operating the lock
After inserting the key, the lock is locked and unlocked by turning the key completely to the
left or right, respectively. It is only possible to remove the key when the lock is locked.
The keys (as well as any spares) must be kept out of unauthorized hands. It is, therefore,
recommended to remove the key after each closing operation and to keep it in a safe place to
which only authorized persons have access.
When a key is lost, we recommend to immediately alter the lock for a new set of keys using
one of the remaining keys of the existing set. To procure a new set of keys, please contact your
dealer, the service department nearest you or the safe manufacturer.
B) Preparing the lock for a new set of keys
By means of the hexagon change key and one of the previously valid keys, the lock can be
re-set for a new set of keys. The old key can no longer be used once the lock has been changed
for the new set of keys. To change the lock, proceed as follows:
Rear view of
the safe door
1. Open the safe door and execute the steps needed
to alter the lock with the safe door open and
blocked in the unlocked position.
2. Now start from the condition of an unlocked
lock of which the previously valid key is in the
end position for unlocking from which it normally cannot be removed.
3. Carefully turn back the key in the locking
direction until you can lightly feel it engage
after turning the key through an angle of approximately 30°. Stop turning the key at this
point and let the old key rest in this position.

4. Insert the hexagon change key into the
change keyhole from the back of the lock
and, as you face the change keyhole, turn
it anti-clockwise through 60°, at which
point it cannot be turned any further.
5. Now unlock the lock again completely
with the previously valid, i.e. old, key and
remove the old key in the end position.
6. Insert one of the keys from the new key
set, to which the lock is to be adapted, into
the lock and turn it as far as possible in the
locking direction.
7. Turn-back the hexagon change key on the
back of the lock clockwise through 60° to
a stop and remove.

8. Next, turn the new key further into the locking direction to the end stop in the locked
position.
9. This completes re-setting; the lock is ready to be used with the new key, which can now
be removed when the lock is locked.
TRIAL RUN - TEST ALL KEYS WITHOUT EXCEPTION !
With the safe door open, test all keys from the new set. Do not close and
lock the safe door until all keys have been checked for proper functioning.
C) Care and maintenance
Keep keys clean; make sure no dirt is entered with the key into the locks interior. The lock
itself is maintenance-free; it must NEVER be lubricated with oil or grease.
