Query: Vinyal window locks.

I have to comment on Amazon and Deerso in having this product. I have been to 4 store that was to carry these. None. These are reasonable price from Deerso. Simple to put on. I order 4, 2 of the keys had the same code. One key did not open the one unit. I contact Deerso and are sending out a replacement for the one. That is customer satisfaction!TomPrime Line Prod.
