Please note:
1. Before depositing ngerprints, it is important that the sensor area is clean and dry. The nger must
also be clean and dry (free from e.g. water, grease, dirt, etc.).
2. The maximum number of ngerprints that can be added is 200. It is recommended that each user
enter at least 2 ngerprints to prevent problems if any nger should be damaged or unusable. Feel
free to add ngerprints from the same nger a couple of times to increase the reading.
3. When ngerprints are added, the nger needs to be read several times. Place your nger on the
sensor at dierent angles each time and with light pressure until the voice asks you to pick up and
press again.
4. When the current strength is too low for the sensor, you are reminded by ashing blue when the
Fingerprint sensor is in use. After the ngerprint is veried, the light continues to ash blue quickly
and the light is slightly dim; in this case, replace the batteries as soon as possible to prevent the
batteries from running out completely.
Care advice:
The lock should be cleaned regularly with a mild detergent and fresh water to remove dirt and salt. This
is to prevent the material from discoloring.
This is especially important if the lock is mounted outdoors where rain does not reach or in a coastal
and oxidizing environment.
5.3 Adding Gateway (optional)
When connecting a new Gateway, your smartphone and your Gateway must be connected
on the same Wi-Fi network using the 2.4 GHz frequency only.

5.4.2 Trouble shooting hardware
Factory reset (after unresolved software problems)
Open the battery door and press the reset button, with a thin
object, for 5 seconds. (Ignore any messages within 5 sec.)
Then dial “000#”. A verication takes place and then the lock is
restored.
1 After installation the display does not light
up.
a) Check that batteries are correctly inserted and that
they have enough power.
b) Check cable between front and back parts is
connected correctly.
2 I can not add ngerprint Finger must be dry and clean. The sensor must also
be dry and clean.
3 Fingerprint verication works well, but
lock can not be opened
Fingerprint lock has two important components: one is
the ngerprint module and the other is the electrical
lock. If the verication succeeds with the lock not
opening, you can listen carefully when the ngerprint
is veried if you can hear the engine sounding inside
the lock. If it is heard, the error is often due to the
handle lock. If the motor is not heard, it is probably
because the circuit board is broken. The front panel
needs to be replaced.
If you have a valid guarantee, this can be invoked.
4 Batteries are draining fast. a) High use of the lock
b) Only use batteries of high quality. Consider the use
of lithium batteries.
5 Can volume be adjusted? Yes.
6 Nothing happens or the lock can always
be opened when you press the handle on
the outside.
Check that the assembly has been carried out
correctly with the arrow pointing in the same direction
as the handle direction.
Also ”Auto-lock” must be activated in lock settings.
7 Display is i not working and/or light is
weak
This probably due to weak battery power. Please
install new batteries and check.
8 How long is the lock in the locked
position after incorrect opening attempts
have been attempted 5 times?
After the 5 sec. alarm, the lock is closed for 2 minutes.
During this time the lock can only be opened through
the app with bluetooth or remotely (Gateway option).
9 How many records can be stored in the
lock?
500 pcs
10 On how many locks can a single RFID
tag/card be used?
Unlimited
11 Lock does not lock. Check that ”Auto lock” is activated in lock settings.
Front and back panels must be installed parallel to
each other. Adjust if needed. Also see p.6 above.
5.4 Trouble shooting
5.4.1 Common questions
1 How to read operation methods? In the ”records” of the main interface / or web
interface TTLock
2 For what reason are you able to upload
ngerprints?
What is uploaded is not ngerprints but the number of
ngerprints. Because some locks do not need the
APP to add ngerprints, they can not be seen in the
APP until they have been uploaded
3 How many e-Keys can be added? Unlimited
4 Why does ”pending” show when sending
an e-Key?
Before receiver has opened App for receiving the e-
Key “pending” is showing.
5 Why do I not receive a one time
passcode?
This may be due to a problem with the operator or the
SMS server, or it may be due to an incorrect
parameter. Remember to enter the mobile number
without the rst zero.
Otherwise contact the support service in the APP.
6 Can users use their account
simultaneously on two devices?
No, that does not work. But you can authorize Admin,
which is on another device.
7 Can I download records/history? With Bluetooth: Yes, otherwise No.
8 Why does Passage mode not work
immediately?
You have to verify Passage mode by performing one
veried opening rst.
9 What is “Automatic lock”? Set the length of time before the lock returns to the
locked position.
10 Why can I not send e-Key? Check if the account you are sending to is registered /
already received.
11 How many locks can be added in the
APP?
Unlimited
12 Is it possible to add Passcodes,
ngerprints or RFID-tags remotely?
A) Auto-genererated Passcode: Can be sent
Custom Passcode: Can be sent if Gateway is
connected
B) Fingerprint: Not possible to add remotely
C) Adding tag/card is possible only through Android
with NFC activated.
13 The lock display is ickering. This can be due to the protection plastic lm has not
been removed from the display. Try removing the lm.
Water may also be the cause, so try wiping the display
with a dry cloth.
APP is being automatically updated regularly. Therefore some functions and features may
vary from above instructions.
