I changed the keychain, it turned out that it was time to change the board, we did everything quickly, now I have 2 keys, everything is clear, I recommend
If you want to leave more money, then go to them. I wanted to make a duplicate of the chiped key, at first they said one price, then doubled it, then 3 times more, eventually I turned to another place where they did the same work, but 5 times cheaper than the final price. I definitely do not recommend it.
