How much does it cost to change the lock core for the rolling gate in Nanning?

In Nanning, if you ask a master who specializes in changing locks to change them for you, it usually costs 50 yuan. Of course, it also depends on how far you call this master, which may be more expensive. However, this kind of ordinary roller shutter lock can not play the role of anti-theft, but can only prevent gentlemen. Thieves can pry open the door from the bottom of the shutter. My shop front has installed a special anti-theft alarm lock for the shutter door, so thieves can never pry it up, and they can also call my mobile phone to call the police.

It feels great! This is their leaflet, parents can refer to it.
