Door Locks – How to Choose a Secure Lock

Interior vs exterior locks

Interior locks provide privacy and basic access control between rooms, while exterior locks must deliver maximum protection against break-ins. Models like the Brava unutrašnja prikrivajuća - gornja ELZETT are ideal for interior doors where aesthetics and simple locking are priorities. Exterior locks require more robust construction and certified cylinders.

What are concealed locks

Concealed locks are designed so the mechanism integrates completely into the door leaf, with no visible parts from the outside. Brands like ELZETT and LEVIOR offer solutions that combine elegant appearance with reliability. These locks are mounted at the top or middle section of the door.

Security levels in locks

European standard EN 1303 defines security classes from 1 to 6, where higher numbers indicate greater resistance to forced entry. ABUS and ELZETT manufacture locks with certified cylinders that meet the highest standards. For exterior doors, locks rated class 4 or higher are recommended.

What to check before buying

Verify your door thickness before purchasing as locks come in different dimensions (35mm, 40mm, 45mm standard). The cylinder type must be compatible with your keys – leading brands like BANE and SRBIJA offer universal options. If replacing an old lock, measure the distance between screws (center distance) to select the appropriate model.

Lock installation and maintenance

Professional installation ensures proper functioning and extends the lock's service life. Cylinders should be periodically lubricated with graphite powder, not oil which attracts dust. If your key enters the lock with difficulty, this signals a need for cleaning or cylinder replacement before complete blockage occurs.
