In addition to the cases encountered, many citizens have asked, and locksmiths often say that this lock can be upgraded and that lock needs to be replaced. So, is upgrading and replacement the same thing? Can all locks be upgraded?
Upgrading and changing locks are two different concepts. Upgrade refers to the transformation of lock core; The replacement involves three key parts: handle, lock body (commonly known as "lock tongue") and lock core.
From the time of transformation, the locksmith only needs ten minutes to complete the upgrade. It takes several times more time to replace, at least one and a half hours under smooth conditions. When the new lock doesn't match the door, you must use tools to modify it repeatedly. So the cost of upgrading is also very different.
Can all locks be upgraded?
"Not all door locks can be upgraded." Beijing Service Center for Urgent Locks and Difficult Locks Repair participated in a community safety tour in Haidu Xili the day before yesterday. Master Ma of the company told reporters that the lock cores of two brands, such as Gentleman and Old Dalian, cannot be upgraded at present.
"These two brands are representatives of the old locks. In the 1980s and 1990s, many people installed it, and quite a few fence-type security doors were in use. However, due to poor security and difficulty in upgrading, it was gradually eliminated. Some citizens called to change the lock. We will first ask him what brand the lock cylinder is and what the key looks like. "
Master Ma said that what happened to Mr. Haiduoxi Li Feng can often be encountered in their daily work. Because some old brands of locks have a small usage and low market share, manufacturers are unwilling to open another mold to re-manufacture the upgraded lock core from the cost point of view, so the old lock core is no longer in the market, and people who want to change the lock are in a situation where there is nowhere to change it.
"About 5% of our customers are in this situation. Usually, we will advise them to replace the door, because the labor and material cost of replacing the new lock is not much cheaper than buying a new door. "
