The blanks are of poor quality. The key is broken in the lock (plastic from metal). The master refused to redo it. He only offered a discount of 5 rubles. Thank you, others are already 5 rubles cheaper, but I don't want to go to you once a month to change the key.
I was making a duplicate of the bolt key. Thank you very much, the key came up the first time! They didn't want to do it anywhere! Then bring the lock, then you will go to redo, and so on. All the best to you! I will contact you!
