What should I pay attention to when matching the house key:

1, not looking for acquaintances to configure.

As the saying goes, acquaintances are easy to handle affairs, but some things are too private to find acquaintances, especially those with house keys. Never look for people you know, because you should guard against people and avoid some people who are harmful to people's hearts with illegal purposes.

2. Key materials are very important.

According to experts from Qijia. Com, the quality of the key is good or bad. If you don't pay attention to the inferior key blank directly used by bad merchants, this key will be damaged or broken in a short time, which is very unfavorable, so you need to pay attention when matching keys.
