Unusable while the product could be great!

This product is sturdy and can contain any type of keys (including the car keys) but the problem is that MasterLock does not limit himself to affix an initial code in 0000, but a different code for each initial copy located on a sticker at the back of the product in the blister! Alas, the quality tests at Master Lock to be reviewed because my sticker .... was virgin! Result, the product that weighs a ton had to be sent to Amazon on the advice of Master Lock, contacted prior to and unable to provide the initial code based on the serial number! But I would've settled for the same product with an initial code 0000!
