Before you replace the door lock, you must consult carefully.


1.There are many types of doors, there are metal doors for outdoor use, and wooden doors that are common indoors. You may worry that the wooden doors will not hold the fingerprint lock. In fact, this worry is superfluous. I have only seen thieves and shackles. Through the door! Probak fingerprint locks can be installed on wooden doors, iron doors, copper doors, composite doors and security doors, with the exception of glass doors. 


2. Confirm the direction of opening the door, Open the door left: You stand on the outside of the door. When the fixed hinge of the door is on the left, the fingerprint lock is defined as the left open door, and the left inner push door and the left outer door open.


Right open door: You stand on the outside of the door. When the fixed hinge of the door is on the right side, the fingerprint lock is defined as the right open door, the right inner push open door and the right outer pull open door.


3, The thickness of the door is an important factor that must be considered when installing a fingerprint lock. The thickness of the door determines the accessories of the lock. Generally, the door thickness corresponding to the smart lock is between 35mm and 100mm. The door thickness outside this range cannot be installed. Therefore, the thickness of the door must be measured at the time of purchase, so that the customer service staff can select the appropriate door lock for you.


4, My home is a double open door, do we need to install two locks?

Strictly speaking, it is necessary to install two locks, one true lock and one fake lock. This is to facilitate the opening of the door, at the same time to achieve visually beautiful, symmetrical, will install a fake lock on the other door, (false lock refers to the same brand, the same type of lock, in order to install in the double door, and one of them The lock cylinder and the lock tongue are removed, and only the outer shell is kept; commonly known as the false lock.) The double-opening door is mostly used by the villa, and the material is mostly metal, so the weight of the door will be heavier than the wooden door.
