LX100 User’s Guide

Introduction

The LX100 is a keyless proximity door lock that fits most
standard doors. Simply replace your existing cylindrical style
door handle with the LX100 for an economical access control
system for your business or home. The locks provide stand
alone operation and do not require the use of a computer or any
external device for programming. They are powered by standard
alkaline batteries eliminating the need for wiring. The LX100
uses radio frequency technology to instantly identify proximity
badges and key fobs. No transaction history is retained.

LX100 Features

• User-installable access control

• 120 user capacity per lock

• Operates for 1 year or 4,000 activations on batteries

• Heavy duty all metal construction

• Lighted display & audio alerts for badge authorization

• Stand-alone operation - no computer required

• One year warranty

• Designed in the USA

Installation

Please refer to the separate Quick Start Guide enclosed with the
lock for basic installation instructions. More detailed installation
instructions, including the preparation of new doors, are
contained in the back of this User’s Guide.

Using the LX100

When a badge or key fob is placed over the reader window of
the LX100, it instantly reads its unique encoded ID number and
verifies that it has been authorized to open the door. The LX100
comes with five preprogrammed badges which can be used
immediately following installation with no additional setup
required.

Master

Badges and Key Fobs

The LX100 supports the use of Lathem proximity ID badges
(included with lock) or optional Lathem proximity key fobs that
users can simply attach to their key chains. The use of badges
or key fobs is an individual user preference, and they can be
used interchangeably on any lock.

A badge or key fob can be programmed to be one of two distinct
types of users of the LX100: Master or User

Master Badges

Badge

Sticker

The Master not only allows access through the door, but also
provides additional administrative rights to the holder so they can
add and remove users as needed. The LX100 supports up to two
(2) Master badges or key fobs. Each Master can add up to 59
individual Users. Therefore, the LX100 supports up to 120 total
authorized users including the two Masters. The LX100 comes
with one preprogrammed Master badge, which is identified by
the global key sticker located in the lower left corner of one of the
badges. This Master badge can begin accessing the lock and
adding or removing users as needed without any additional
programming (see Adding a Master).

Page 6

LX100 User’s Guide

User Badges

A User badge or key fob allows access through the door. User
badges or key fobs are added by a Master badge. There can be
up to 59 User badges assigned to each Master card. The LX100
comes with four (4) preprogrammed User badges. These
badges do not have the global key sticker like the Master badge.
These User badges can begin accessing the lock immediately
with no additional programming needed.

Backup Keys

The keys enclosed with your LX100 are for backup purposes in
the event of badge loss or battery failure only. Keep your keys in
a protected and easy-to-remember location OUTSIDE of the
room the lock is on. Lathem does not manufacture or stock extra
keys. You are responsible for their safekeeping.

1. The keyhole cover is attached using a high-powered magnet.
Your backup keys also have a smaller magnet embedded on
one side to assist in removing the keyhole cover. Or, you
can use your fingernail to pry open the cover.

2. After removing keyhole cover, place key in keyhole with
arrow and notch pointing up to align with dot above keyhole.

3. Insert key and turn to the right until key stops.

4. While key is turned, push handle down to open door.

“Meeting Mode” Setting (Lock Bypass)

Warning: Meeting Mode disables the lock and bypasses the
use of badges for authorization. When in this mode, the lock

will function only as a door handle. These badges will serve as
“on/off switches” if a room is being used for a long meeting, etc.

1. The badge(s) you assign to Meeting Mode will serve this

function solely and cannot be used as a User badge. So,
if you have a badge that’s been programmed as a User
badge and want to reprogram it as Meeting Mode badge,
you must first clear the User badge programming as
previously described in “Deleting an Individual Badge”.

2. Remove Interior handle & place Master badge on display

Using Multiple Locks

If you have purchased multiple LX100s, you can configure and
change the badge accessibility to each of your locks as you
prefer. Remember that each lock is stand alone which means
you must program them individually. However, this also means
you have greater flexibility to customize access to rooms as
employees or work areas change.

For example, if you want to program a User badge from Lock #1
to also access Lock #2, simply use Lock #2’s Master badge to
add it to Lock #2.

Please note: We suggest you maintain a list of which badges are
programmed to which locks (example below), location of
emergency backup keys and Meeting Mode badges. Keep the
list updated frequently.

Maintaining the Lock

The Lathem LX100 is designed for years of trouble-free
operation. The only routine maintenance typically required is the
changing of batteries and occasional cleaning.

You should routinely check your batteries every few months
depending on the usage of door.

LOW BATTERY INDICATOR: When the batteries begin to run
low, you will see the Red light flash and a beep after badges are
used. You may also notice that the volume of the beeps
decreases. Change all four batteries (AA alkaline only) as soon
as possible.

Clean handle by spraying a small amount of glass cleaner on to
a towel and wipe handles with soft towel.

Periodically inspect handles for tampering, vandalism or “wear
and tear”. After a period of usage, you may find it beneficial to
retighten the connecting screws by removing the Interior handle
and using a screwdriver.

3. Insert axle (short axle for thinner doors, longer axle for

thicker doors included) into center turning hub. Make sure
the “dot” is up on the turning hub and holes are vertical
on axle.

4. Insert securing pin downward thru top of turning hole, thru
axle until pin is completely thru.

5. Bend “legs” of pin outward around turning hole to secure.
You may require pliers to do this.

Page 21

latch in place or remove it and replace with the latch
included. To expand latch for larger door hole, hold front of
latch with one hand and pull on center axle hub. Make sure
that latch slope faces the same direction the door closes.
Secure with 2 small latch screws provided.

7. Place Exterior handle on door: Guide wire thru door hole
over top of latch assembly. Place connecting pillars thru
latch holes and axle thru center hole. Make sure the dot is

still up on the axle turning hub.

Page 22

LX100 User’s Guide

8. Push thru and allow Exterior handle to rest in latch.

9. Run wire thru rectangular opening in battery pack (to side of
center hole).

10. Secure battery pack with 2 long connector screws at each
side of opening into connecting pillars.

Page 23

Lathem Security Solutions

11. Make sure Exterior handle and battery pack are straight as
you tighten connector screws.

12. Connect wire to circuit board underneath the bottom battery
on the battery pack. Observe how pins align with plastic
connector.

13. Push back any excess wire thru the rectangular opening.

Page 24

LX100 User’s Guide

14. Install 4 new AA (1.5 volt) alkaline batteries (not included)
into battery pack on Interior handle. Make sure they are

installed in the correct direction and are firmly seated in
position. You will hear a buzz, indicating the lock is

energized.

15. Place Interior handle cover over battery pack and secure
with 2 screws on top and bottom. Do not over-tighten the
Interior handle! Doing so may affect the performance of the
lock.

Preparing a New Door

Verify that your new door is 1 3/8” – 2” thick.

1. Use the enclosed “Door Cutting Template” to mark your drill

holes.

Note: Position template at correct height (suggested:
38” or 97 mm from floor). Mark center for lock hole.

2. Drill 2 1/8” hole through door. Do this by drilling once

from each side to center of door to avoid damaging door.

3. Drill 1 1/8” latch hole being sure to align the center of the

latch hole with the center of the main door hole.

Page 26

LX100 User’s Guide

Latch Installation

Use enclosed “Strike Plate Cutting Template” to cut and
install latch in door as indicated below.

1. Insert latch into 1 1/8” latch hole in “width” of door. Latch
is expandable, depending on the size of your door hole,
to 2 ¾”. To expand latch, hold front of latch with one
hand and pull on center axle hub.

2. Trace around the perimeter of the latch faceplate to
create your chisel border. Remove latch in order to
chisel.

3. Chisel out wood as indicated on template (1/8”) until
faceplate fits flat with door edge.

Important: Be sure to install the latch to match your lock
(Right or Left hand).

4. Make sure that latch slope faces the same direction the
door closes.

5. Fasten latch to door with 2 small latch screws.

Strike Plate & Dust Boot Installation

1. If you are installing on an existing door jamb, you may be
able to use your existing strike. However, it is recommended
that you use the strike included.

2. On a new door, use the “Strike Plate Cutting Template” to
mark and install the strike plate. Center the metal strike plate
over the dust boot with the curved edge facing the interior of
the room. The goal is to have the metal strike plate flush with
your door jamb.

3. Insert dust boot and secure strike plate with screws provided.
Test opening and closing of door and adjust as needed.
