In fact, in the purchase process, the unlocking film is an important concern, and his quality determines the quality of the lock.

Pay attention to the following points when choosing a door lock:

1. Compared with the weight of the lock, the heavier the more, the thicker and harder the material of the lock cylinder; on the contrary, the material is thin and easy to damage.

2, watch the surface finish of the lock, whether it is fine and smooth, no spots.

3, try to buy the brand's high-profile locks to ensure quality and durability.

4. Repeatedly open to verify the sensitivity of the lock cylinder spring.
