The smartest safe lock in the business.
4.0 SERVICE
You are encouraged to familiarize yourself with Sherlock. Understanding its features and characteristics will
drastically diminish the need for assistance. However, should you experience difficulties, you may call 1-800-
452-4655 (812-948-8400 outside USA) to speak to a factory technician. This telephone number is monitored 24-
hours a day. Although you may experience a reasonable delay during evenings and holidays, a technician
will return your call promptly. Do not call your local locksmith for service! Service must be coordinated and
approved by Fire King Security Products to be covered under warranty conditions.
4.1 TROUBLESHOOTING
Safe will not allow access
to any authorized em-
ployees.
PROBLEM CORRECTIVE ACTIONPROBABLE CAUSE
Time lock.
Sherlock is equipped with a
timelock feature.
If the safe has entered the time lock pe-
riod, you must wait for the time lock pe-
riod to expire in order to access the safe
(usually the next day). Only User 29 or User
30 can edit the timelock settings.
Lost PIN. Sherlock uses the employee PIN
as an assurance against unautho-
rized use. The factory does not
have access to your PIN, nor can
your user number be made func-
tional without it.
Contact your supervisor for further assis-
tance. Suggested action is to re-enroll the
affected user number with a new PIN.
Message:
ERROR DELAY
Your PIN was entered incorrectly
five consecutive times.
Sherlock will not respond to your touch for
10 minutes.
No display and no re-
sponse to keypad touch.
The most likely cause is loss of
AC power. Check the power sup-
ply is plugged in and that the out-
let is providing power. Check that
the power supply is plugged into
the safe.
Plug in the power supply and ensure the
outlet has power. If Sherlock remains in-
operable, call the Fire King Security Prod-
ucts Technical Service department.
4.2 PREVENTATIVE MAINTENANCE
Your Sherlock electronic lock system should provide you with years of trouble free performance. We do
recommend that you regularly wipe the keypad and display with a soft cloth with rubbing alcohol (use
sparingly). Use rubbing alcohol and a cotton swab to clean keypad key contacts. Use a pink eraser to clean
keys. Do not attempt to wash your safe’s hinges or other moving parts and never use any cleaning chemi-
cals, water, or other liquids on exposed electronics.
Error Message: Invalid
Key.
The key contacts are dirty, it is
not enrolled or has been dam-
aged.
Clean the key contacts with a pink eraser.
If the key still indicates invalid, check the
employee key count for an open User Num-
ber and attempt to reenroll the key. If the
key will not enroll, replace the key. If no
keys respond or if all keys indicate invalid,
contact Fire King Security Products Tech-
nical Support.
