Dachuan Security Door After - sales Service
Dear Dachuan Security Door Users:
Thank you very much for choosing Dachuan security doors. We are always committed to creating a safe and warm living environment for you.

Just dial the after - sales hotline 400 - 6789 - 442, and our professional and enthusiastic after - sales team is always ready to solve problems for you and become your most solid backup.
I. Common Problem Scenarios
- Unsmooth Door Opening and Closing: During daily use, if the security door is difficult to open or close and has a stuttering feeling, it may be due to dry and under - lubricated hinges, or hinge deformation caused by long - term use. The internal components of the door lock are worn and loose due to frequent opening and closing, resulting in difficulties in turning the key in the lock core, or even inability to turn, which will seriously affect your normal access.
- Door Lock Failures: Common issues include the door lock being unable to lock or unlock normally. For example, the fingerprint recognition function fails to recognize your fingerprint multiple times, and you can't unlock the door even after entering the correct password. The electronic lock display shows garbled characters or a black screen, and the operation buttons fail. The lock tongue of the mechanical lock cannot extend or retract smoothly. These failures not only inconvenience your life but also may pose a threat to home security.
- Door Body Damage: When you find that the door body is deformed, dented, or cracked, it not only affects the appearance of the door but also may reduce its anti - theft performance. The door seal strip is aged or falls off, resulting in poor sound - insulation and heat - insulation effects. The peephole is damaged, and you will be unable to observe the situation outside the door normally, leaving potential safety hazards for your home.
