FAQ
Pre-purchase
Are the products suitable for any kind of doors?
Most of the models are designed for doors measuring 40mm~60mm in tickness, but slight deviations form this limit are still acceptable. Nevertheless, door in Singapore and Malaysia are generally of the recommended tickness. In terms of materials, all types of doors except for glass doors are suitable. Metal doors are also suitable but require further advices. For more information, please refer to our product specification details on the brochures.
Where are the door locks manufactured?
All the door locks are manufactured and quality-checked in Korea.
Functions
Can the lock still operate if there is a power failure?
Definitely! The lock operates standalone on batteries so a power failure will not affect its operations.
What types of batteries can I use?
You must use normal AA ALKALINE batteries and replace every battery at the same time. Over discharged or faulty batteries may cause leakage. Check the batteries and its compartment for any leakages every 3 to 4 months as damages due to battery leakages will not be recovered by warranty.
How do I know when to replace the batteries?
The battery replacement alarm will go off one week before the battery is about to go flat. The indicating lamp (the round rim of light) will blink in red to alert you to change the battery. The lamp will illuminate in blue when the door is working.
What if the batteries go flat?
You can either use the mechanical override key (if available) to open the door or contact the 9V battery to the emergency power supply plate to supply instant power to the door lock
Will the registered password and fingerprints/ cards be deleted when the batteries go flat?
No. The password and fingerprints/ cards are recorded in an onboard memory chip, so the storage is permanent and the registered information cannot be deleted unless you change the password or reset the system.
What is RESET?
A reset simply restores factory settings and all fingerprints/ registered passwords will be deleted, keeping only the original master password
Can the fingerprints or cards be deleted?
Yes. All registered fingerprints or cards can be deleted by using the current password. The erased fingerprints or cards cannot be used to open a door.
What kind of card is suitable for usage?
The card has to contain an RF chip (Mifare Type A, 13.56Mhz) e.g. SMART card, Kopitiam card, staff card. One RFID card can be registered in many locks because it's the motherboard that reads and recognizes the card.
Why is there a need for the mechanical override key when the door can be operated by fingerprint, card or password?
card or password?
You can use this key and open the door in the event when the batteries run out or when the door lock is malfunctioning. You are advised to keep one of the 5 mechanical override keys provided in his/ her vehicle or with a relative, in an event of emergency.
Can the mechanical override key be duplicated?
No. The key mould is unique and specially fabricated by Samsung in Korea.
What if the mechanical override key is lost?
Authorised distributor is able to replace the whole key cylinder with a new set of 5 override keys
What is an anti-panic opening system?
An anti-panic opening system allows you to unlock the door from inside the house by turning the handle. This is to facilitate immediate evacuation during emergency situations.
What is the fire alarm installed in the lock for?
It has a thermal sensor in the door lock which will detect a fire. A warning alarm will be given off (the function is not selectable and set as factory default) and the door will unlock itself to ease escape.
Is the lock waterproof?
No. Although an exposure to a minute amount of water is harmless, the door lock is designed to be used indoor or under the shelter.
Why is my fingerprint not detected by the sensor even after I have registered it? What can I then do?
Firstly, this may occur when the fingerprint is positioned differently as compared to when you register it. For the fingerprint to be detected, the difference must not exceed a certain tolerance. Please try again with different fingerprint positions.

Secondly, due to genetic differences or the nature of the occupations, some people tend to have thinner fingerprint lines so the system may have difficulty detecting the fingerprints. If that is the case, the person can use the password or the emergency key to open the door.
Can I use a remote controller for the lock?
Yes. You may register up to maximum 2 remote controls for the mortise doors. The remote controllers are optional and can be purchased at an additional charge.
Can my door be forcefully opened?
No. Besides the double locking function, an additional layer of protection is achieved through the intrusion alarm. If any incorrect password is entered for 3-5 times consecutively, a warning alarm will sound (Biri ~ Biri ~ Biri) for 10s and the door-lock will not work for a minute.
What is the double locking function?
Once the double locking function is chosen by pressing the open button and holding it, the door is also locked from the inside. In other words, the system does not accept any access from outside unless the function is cancelled or a mechanical key is used to open the door. This serves to further enhance the security by preventing intrusion, especially at night.
Design
What is it about the design that is different from other brands?
Like any other SAMSUNG products, the designers emphasize on elegance and style. The screws are well-hidden from view and so is the mortise lock because it comes with a built-in hidden door sensor.
