Check the labels and the marks on the of product's packaging (including the executive standard, the grade, the name of the manufacturing enterprise, the location and the date of manufacture) are complete or not. Make sure the package is firm and the content of the product specification is consistent with the product. Be aware of the exaggeration in content so that the products will be inconsistent with reality.
Observe the quality of the product's appearance including whether the cylinder, the lock body, the lock latch, the lock handle, the lock surface mount components and relevant parts are complete, whether the appearance of electroplated parts and spray painted parts have bright and even finish, and whether there are signs of rust, oxidation or damaged parts. 

Check whether the locks are reliable and flexible by comparing the locks with at least two other locks. Especially when buying a two-way lock, you need to use all the keys to switch on and off the inner cylinder and the outer cylinder as a test. 

Then check the bits of keys such as keys with 5 key teeth. Each type of keys should not have key teeth less than 3, and neither the first tooth nor the fifth tooth should be the deepest key tooth, which is good for the insertion and extraction of keys and makes keys not easily broken.
