Last year, I replaced only the lock cylinder. Recently, after closing and locking the door, the indoor key got stuck and couldn't be removed. The cylinder is loose inside the lock body and doesn't fit tightly. After inspection, the technician confirmed the root cause: it's not just cylinder wear.All internal springs and clips of the complete lock body are aged.Replacing just the cylinder won't fix the issue. You need to replace the entire set—door handle, cylinder, and full anti-theft lock body—to permanently solve recurring lock failures.

In reality, the quoted price only includes a single lock cylinder; additional fees apply for the lock body and door handle installation. This is a typical example of...Low-price bait tacticsA homeowner in Hebei District needed a full lock replacement on the same day, as they were leaving the next morning. After comparing several locksmiths and distrusting low-cost, unlicensed technicians, they chose our local licensed unlocking team.
