Models 6120 and 6123—Motorized Electronic Combination Locks
Installation Instructions
instAllAtion notes
Although the 6120 series is easy to install, we recommend
the following procedures be performed only by an experienced
locksmith or safe technician. Your safe may incorporate
relocking devices that are attached to the combination lock.
Misalignment or detachment of these devices can result in a
lockout—a condition that makes it unlikely that the safe can be
opened without damage.
AdditionAl items you will need
The 6120 series requires two 9-volt alkaline batteries (not
included). We recommend fresh Duracell
®
batteries. Do not use
old or partially drained batteries in your lock. New batteries will
power your lock for approximately 8,000 openings when used
without the time delay feature.
Many installations can be performed with nothing more that
a medium Phillips screwdriver. If the manufacturer of your
safe has made external relock device attachments to the lock,
specialized tools and knowledge may be required.

Step 1
Remove the existing lock (if present). The mounting plate should
be smooth and flat, with
1
⁄4-20 mounting screw holes. The wire
channel (spindle hole) must have a diameter of at least
5
⁄16”.
The 6120 series can be mounted right-hand, left-hand, vertical-
up, or vertical-down without any modifications or adjustments.
Step 2
Use a reamer or round file to remove any sharp edges from the
wire channel (spindle hole) that might damage the wire cable.
Run the connector through the wire channel. Gently pull the
connector and all excess cable to the outside of the safe. Make
sure the cable is not crimped or stressed at any point.
Step 3
Once you’ve made sure the wire cable is not crimped or in
contact with any sharp surface, attach the lock to the safe’s
mounting plate. Use the four
1
⁄4-20 (or metric M6) screws
provided. Tighten securely, attaching the lock firmly to the plate.
The lock incorporates a bolt-through cover that allows mounting
with the cover in place. Removing the cover voids the warranty.
