The first thing to consider when unlocking and changing the lock of the security door is the labor cost. You can know the specific price if you buy the lock core yourself. If the installer brings his own installation, the price will be more expensive. Generally, the cost of doors is around 30 yuan, and the installation requires additional fees, and the prices of various locks are also different.
In addition, the price of anti-theft door locks should also be considered. At present, the price of anti-theft door locks ranges from tens to hundreds of yuan, and there are also several thousand yuan of door locks. The more popular anti-theft door locks are generally concentrated in several hundred yuan. Different brands of anti-theft door lock cores have different prices.
For example: American Didi B-class lock cylinder 89 yuan, Golden Point Atomic Super B-class blade tinfoil lock cylinder 299 yuan, American and Japanese Super B-class lock cylinder 180 yuan, Ma Yuechao B-class lock cylinder 226 yuan, Yi Chao B-class security door lock cylinder 78 yuan.
Some points to pay attention to when unlocking
1. Call the lock master, first ask if there is a lock certificate, and then tell him what it is. Negotiate the price with the locksmith. If you think it's suitable and the price is acceptable, then you can tell the locksmith your details. Address, if you think it is inappropriate, please don't tell others your specific address at will.
2. Please don't contact with other people before the lock opener arrives, so as to avoid the embarrassment of two groups arriving at the same time. Some people may feel that they have run away for nothing and ask you for oil. If you fiddle with the door on the way to the lock opener, be sure to inform the lock opener in time.
3. When the unlocking personnel arrive, be sure to find his work permit, and pay attention to check whether it is the same person and whether it has been registered by the police.
