Digits are randomly displayed on the key pad ensuring access codes to be undetectable to 

intruders after repeated use. To experience the patented and innovative key pad software, powered 

by PIN Genie, please download the PIN Genie Vault App from iOS App Store or Google Play. 

Store up to 8 Access Codes for family, friends, and guests, as well as monitor entry and exit 

records.

Biometric Fingerprint Recognition protocol allows up to 99 registered fingerprints to be used and 

accepts only actual fingerprints - preventing lifted prints from being used.   

The exterior displayed keypad can be locked and switched off using the simple ON/OFF toggle from 

the inside panel. The owner can prevent others trying to input the passcode from the outside and 

entering the home

 

The offline magic key can allow owners to issue access codes, set the allowed access duration, all 

without Lockly ever connecting to the internet, so in case of power outage, you can still magically 

and remotely issue Access Codes without any connection to the web.

Owners no longer have to worry about forgetting to lock the door. With Auto Lock enabled, Lockly 

Secure Plus and Secure Pro will automatically re-lock the door after 30 seconds.

The door can be opened with physical backup keys. There is also a 9V battery connection socket 

for emergency power backup to access the key pad in case your smart lock runs out of battery.

The Default Access Code is

After the installation of your new Lockly Secure Plus / Pro, understanding some key functions 

of operating your smart lock is important.  The following guides will walk you through resetting 

a lock, adding Access Codes, deleting Access Codes, adding and deleting fingerprints 

(applicable to Secure Pro only) and also how to configure your OMK (Offline Magic Key).

For any questions you can always visit http://support.lockly.com for assistance.

Don’t forget that the Secure Plus and Secure Pro works best with our iOS and Android app.  

Please download the app by visiting the link below. 

In order to restore the Lockly Secure to factory default settings, you must have your “Initial 

Code” available.  The Initial Code can be found on the VIP Card that came with your smart 

lock. 

After you have the Initial Code ready, push the reset button on the back panel of the Lockly 

Secure to perform your reset. See below to see which Reset Process applies for you. Once the 

smart lock has been reset,  all the data previously stored will be deleted. 

The exterior keypad screen can be locked and 

turned off by using the ON/OFF switch at the back 

panel (interior) of the smart lock. When it is 

switched off, people who are outside cannot enter 

any access codes to unlock the door.

Reboot Lockly in case of dead battery or malfunction. No 

settings will be changed and all Access Codes will still be 

stored within Lockly.

Press and release the reboot button when you want to reboot the lock. Your Lockly will beep 

once after reboot. Only reboot when necessary.

To reboot, find the reboot button located on the bottom of the exterior side of Lockly Secure.  

The reboot button is located in the middle of the two 9V battery backup sockets.

You will need something small such as a paperclip, to press the reboot button. Insert the paper 

clip and press down firmly. 

When the battery is in seriously low condition, Lockly Secure will make continuous beeping

sounds in addition to the flashing low battery icon on the touch screen. You should replace 

batteries immediately to avoid your smart lock from shutting down.

.

Battery Icon on the display keypad 

will light up to indicate low battery.

Replace batteries immediately to 

avoid battery failure.  Lockly 

Secure can still operate up to 300 

cycles in low battery condition.

When there is no display and sounds;  

and screen is non-functional.

Replace batteries immediately.  

Supplied physical backup keys 

can be used to unlock the door.  

Alternatively, use a 9V battery as 

shown below to temporarily 

activate the lock. 

Your Lockly Secure will automatically 

detect battery polarity. So hold your 9V 

battery lead in place against bottom of 

the Lockly Secure to 

activate

unlocked your door with your 

.  Once unlocked, batteries should 

be replaced immediately.

Under normal use, the Lockly Secure’s battery will last up to a year.  Please check battery 

levels regularly and change your batteries when the low battery notification is issued.  For 

best practice, always use new batteries.

Open the battery compartment cover and insert four (4) new AA alkaline batteries as shown.

- Make sure the batteries are oriented correctly. 

- Replacing the batteries do not reset stored Access Codes.

The Default Access Code is

Your new Lockly Access Code can be any combination of 6 to 8 digits.

Once a new Access Code is entered, the Default Access Code of 123456 would be deleted.

A Maximum of 8 sets of Access Codes can be stored for use.

There are a total of five (5) buttons on the keypad as

In this section, you will learn how to register a fingerprint to your new smart lock.  Fingerprint 

registration is only available in the Lockly Secure Pro, and not available in Secure and Secure 

Plus models.  If you have Secure Plus, you may skip to Section 4.1 to learn about locking and 

unlocking your door with Lockly.

We are using an advanced biometric sensor, providing the most secure fingerprint authentication. 

For security reasons, Lockly will only accept fingerprint patterns that consist of cross intersection 

points. Patterns with no cross intersection points will not be acceptable.

Please check your fingers before registration to make sure the finger you want to register will be 

acceptable by our system. Otherwise, use an alternative finger to ensure successful registration. 

The following examples show which types of fingerprint patterns will be acceptable. It is highly 

recommended to enroll at least one finger from each hand in case the hand you are using is 

unavailable, such as, in instances like if you are holding items in that hand or have sustained an 

injury.

Upon pressing “FP”, you will enter Fingerprint Registration Mode and you will see a green 

LED ring light up on the fingerprint panel on the exterior side of Lockly Secure Pro. 

Once you’re in Fingerprint Registration Mode you will see 

two numbers displayed on keypad.  The top number is your 

Fingerprint Registration number, in this example to the left, 

“1”. The bottom number will always start with a “6”. 

You must successfully scan your fingerprint six (6) times for it 

to properly register.  Every time you scan your fingerprint, the 

number on the bottom will change, starting from 6 - then 5, 4, 

3, 2, 1, until the fingerprint is successfully registered.

Note: For reference, please keep a record of your fingerprint 

registration number to distinguish whom it was registered to. 

The Secure Pro can register up to ninety-nine (99) fingerprints. Please read the following sec-

tions if you want to add or delete fingerprints.

The fingerprint sensor equipped in Lockly Secure Pro is loaded with powerful fingerprint 

algorithms to extract quality features from fingers, even in poor conditions.  Placing your 

finger on the sensor correctly helps consistency in fingerprint recognition.  The following 

directions and tips will guide you on how to scan an optimal fingerprint image.

Position your finger on the 

center of the sensor

Scan your finger by lightly placing your designated finger on the sensor until you hear a beep.    

Lift your finger and repeat the process slowly until the digit “6” shown on the screen 

becomes “1”.  If you have successfully scanned and registered your fingerprint, you will hear 

a long beep, and the Bluetooth icon will flash green.

PASS will show on the keypad and press OK to exit.  If you did not successfully register your 

fingerprint, FAIL will show on the keypad.  If FAIL is displayed, press OK to return to the 

previous screen to rescan your finger.  

For instructions on scanning an optimal fingerprint, please proceed to Section 3.7.

Please make sure your fingers are clean from dirt and oils 

before scanning your fingerprint.  Make sure the sensor is 

also clean by taking a soft cloth and wiping the surface.

• Place your finger to completely cover the sensor with maximum contact surface.

• Position the center of your finger (core) to the center of the sensor.

• Hold your finger still for more than a second until you hear a beep.

• Scan a finger that is clean and free from dirt.  If a finger is cracked and dry, lightly moisten 

the finger to improve recognition.

• Children ages 12 and under are not recommended to use fingerprint access due to the 

constant changes of their fingers during growth.

• Elderly with fading fingerprints may have difficulty in recognition.

• If your finger has a cut, scar, or cracked skin due to dryness, try another finger.

In case of poor fingerprint conditions

• If wet - wipe excess moisture from finger before scanning

• If dry - moisturize or blow warm breath over finger before scanning

• If dirty - wipe stains and dirt off from finger before scanning

• Make sure the sensor is clean from dirt or smudges - wipe sensor with soft cloth regularly

The Offline Magic Key (OMK) is a unique feature to the Plus and Pro Series.  It allows you to 

grant access to guests remotely without guests needing to download the app.

To use the OMK feature, make sure you download the Lockly app for iOS or Android first, and 

sync your smart lock to your mobile device.

From there, you can then issue an Offline Magic Key within the app.

Go to “Access Management” and choose “Add a New Offline Magic Key (OMK)” and 

follow on screen instructions to generate your Offline Magic Key.  

Each lock can issue up to 50 OMK Access Codes before you have to reset and reissue 

another set of 50 codes. Your app will generate some to follow directions automatically for your 

guests to use.

OMK Codes are issued to the guest by asking them to enter a 6 digit number, followed by a 4 

digit number, followed again by a 4 digit number, entering            in between every set of 

numbers. See the following example.

Guests’ Access Codes

OMK Configuration Number

Once a sequence like the one above is entered, it automatically activates an OMK Access 

Code to be used for a specific duration of time.  In the example above, the Guest’s Access 

Code will be 234567 to unlock the door.  0987 is the Configuration Number that sets the total 

duration of the Access Code, whether it’s a 1 time use code, 1 hour duration code, or 30 

Days.
