What are possible reasons for door lock block failure?


Possible causes of door lock block failure:

Component aging: Prolonged use or unfavorable environmental factors can cause the components of the door lock block to age and lose elasticity or function.

Circuit problem: The door lock may malfunction due to failure or short circuit of internal circuit.

Electromagnet problem: The electromagnet in the door lock block may have failed or damaged, being unable to engage or disengage properly.

External damage: The door lock block may have been damaged or deformed due to a collision or external impact of the vehicle.

Lubrication problem: Lack of lubrication or insufficient lubrication in the door lock block can result in increased friction or component jamming.

Improper operation: Frequent or improper use of the door lock block may lead to component wear or malfunction.

Advantages of vika door lock block:


Steel: DC03 steel material from Baosteel is adopted for vika door lock block. Thanks to a quenching process, it provides excellent tensile properties, and greatly improves the performance of the block. The surface is treated with zinc nickel alloy, which leads to excellent resistance to corrosion and aging.

The rubber pad is soft, and the mold forming process leads to neat and elegant appearance.

Plastic: The plastic used for vika door lock block is made of polyformaldehyde 100T from DuPont, a globally renowned brand. It ensures stable internal structure and top gear quality, and avoids deformation even after long use.

Selection of core parts:

Micro motor: Based on OE quality requirements, the micro motor, as a core component of the vika door lock block, is supplied by "Mabuchi" and "Johson Electric", both well-known brands worldwide. It fully guarantees high performance of the door lock block.

Touch switch: The touch switch of vika door lock block is provided by Taiwan-based ZIPPY brand. It ensures adequate control of the door lock block during the operation of central control lock.

Spring: The spring structure is manufactured in line with OE product parameters and processes, resulting in smoother lock block switching.

Grease: Sufficient German FUCHS lubricant is used, with a working temperature range of -40℃ to 130℃.

The rotary snap of vika door lock block is made of DuPont 5526 material, which features excellent tensile strength and toughness, higher wear resistance, lower noise, and good shock absorption effect.

Production process comparison:

The circuits and injection molded parts of vika door lock block are formed in a single process before glue sealing. This prevents oxidization of the circuit boards and enables stable current and signal transmission for long.

The lower shell of the vika door lock block is equipped with a custom silicone sealing ring, which effectively prevents jamming of internal parts due to ingress of dust and debris.
