Door locks are hardware accessories that are repeatedly used every day. Proper maintenance can effectively prevent malfunctions such as loose handles, lock cylinder jamming, and rust on door locks, extending the service life of locks. Many door locks are damaged not due to quality issues with the product itself, but rather due to long-term lack of maintenance and improper operation.

Do not forcefully drop the door when opening or closing it in daily life, as violent impact can loosen the fixing screws of the lock body and cause the lock tongue to be misaligned. When cleaning the surface of the door lock, wipe the dust with a soft dry cloth and do not directly spray strong acid or alkali cleaning agents to prevent corrosion of the coating, which may cause the handle to fade and rust.

If the lock cylinder experiences key jamming during insertion and removal, do not drip edible oil into the interior. Oil and grease can easily accumulate and clump, exacerbating the blockage. It is recommended to use specialized lock cylinder lubricant. Regularly check the fixing screws of the door lock panel and handle, tighten them in a timely manner if they become loose, to prevent the handle from shaking and falling off.

Door locks in humid environments should be wiped dry of surface moisture in a timely manner to reduce oxidation and rust. When not in use for a long time, simply clean the surface of the lock and keep the lock body dry. Once problems such as the tongue not rebounding smoothly or the lock cylinder getting stuck are found, do not forcefully twist the key. It should be repaired in a timely manner to avoid the key breaking in the lock hole.

Regular maintenance of door locks can ensure smooth operation and continuous protection of home safety.
