Customized Lock Cylinder Replacement Service

We offer customized on-site service for customers who only need to replace the internal lock cylinder and do not wish to replace the entire lock. This is suitable for situations such as aging lock cylinders, keys that are difficult to use, lost keys requiring reconfiguration, and those who wish to replace the lock cylinder with a different specification based on their actual needs.

After the customer submits their appointment request and pays a service deposit, we will understand the existing lock type, installation location, and the problem the customer wants to solve, and schedule an on-site appointment based on the appointment information. Upon arrival, our staff will inspect the existing lock and lock cylinder structure to confirm suitability for replacement before disassembling and installing.

After the replacement, we will check the key insertion, rotation, and the lock’s open and closed states. If discrepancies are found between the original lock structure and the appointment information, we will first communicate with the customer to determine if adjustments to the service are necessary.
