Dierre Lock Repair
If the key turns stiffly, there is play, or the latch doesn’t fully engage, the lock needs repair. We fix faults on-site, preserving the original Dierre construction.
Common malfunctions:
- wear of the cylinder or lever mechanism;
- deformation of the latch;
- misalignment of bolts;
- jamming due to dirt;
- breakage of the spring mechanism.
Repair takes from 30 to 60 minutes. If necessary, the specialist will select original Dierre parts.
