Indoor Door Locks

How to choose indoor door locks

1.Choose products with high reputation, stable quality and good after-sales service.

2.Check whether the logo and logo of the purchased product are complete (including the product's 

implementation standards, grades, manufacturer's name, address, production date), whether the 

package is firm, and whether the contents of the manual match the product.

3.Observe the appearance quality of the product, including the lock head, lock body, lock tongue, 

handle and cover plate parts and related accessories. Is the surface color of the plated parts and 

painted parts bright and uniform, with or without signs of rust and oxidation and damage.

4.Check whether the function of the product is reliable and flexible. Two or more products should 

be selected for comparison check. Especially when purchasing the two-way lock product, the inner 

and outer locks must be tested with all the keys. You should also check the insurance structure of 

the product. It is recommended to try each lock at least three times.

5.Check the tooth condition of the key, such as five spoon teeth, each key should have not less 

than three different key teeth, and the first tooth and the fifth tooth should try not to choose the 

deepest key tooth, which is good for the key insertion and removal. And not easy to break.
