The most widely used security doors in Pan Pan are Bao De 'an, afs, Shen Man Xiao Shuai Lock and Wang Li Senior B Lock. In addition, Jingjing, a high-end brand of Pan Pan Group, uses imported locks. You ask: Is there a difference between the original lock core of Pan Pan security door and that of the unlocking company? It doesn't have to be like this. For example, the ex-factory price of the lock core of Baode lock is between 20-50. It's the same everywhere, and it's not fake. Fake or imitation may be better than Baode's, and some lock companies give you better locks than Pan Pan's after-sales locks.
Looking for a lock company may not be as good as the after-sales lock in Pan Pan.
1 If your security door is an Baode security lock, which one is cheaper (provided there is a B-class lock core)?
If it is the brand of Zhongshan AFS, it is all the same.
If you are handsome, you can choose anywhere.
If Jingjing is a security door, find a manufacturer in Pan Pan.
For your reference, if you can upgrade the guardian blade lock, you'd better buy a blade lock instead, which is much safer than buying a super B lock core. Buy a lock to change it for safety.
