Door Lock Troubleshooting Service

We offer on-site inspection and repair services for door lock malfunctions such as jamming, keys failing to turn, lock cylinder abnormalities, lock mechanism failures, and handle/lock body misalignment. Customers do not need to disassemble the lock themselves; they can submit a description of the problem and we will arrange appropriate on-site service.

After paying a deposit, we will confirm the specific address, lock type, malfunction, and available service time with the customer. Upon arrival, we will conduct an on-site inspection of the lock and door to determine if adjustments, repairs, or replacement of relevant lock components are possible. If the existing lock is no longer usable, we can arrange lock replacement service depending on the on-site conditions.

For issues involving the lock cylinder, lock body, handle, or other lock components, we will determine the appropriate solution based on the specific circumstances. If additional materials, lock replacement, or adjustments to the originally scheduled items are found on-site, we will explain this to the customer before proceeding for their confirmation.
