Creekside Emporium LLC is based out of upstate New York. We have been doing business on the internet since the early 90's. I have the fortune to see new products come onto the security scene before they even hit the shelves. I have seen many "fads" come and go over the years and have never seen a product like the AP501. There are many keyless locks on the market today biometric, digital, mechanical all of which have pros and cons. I feel the AP501 is by far the best when it comes to features, reliability, durability, and service after the sale. I have been a locksmith by trade since 1991 and love my field. I have extensive knowledge of locksmithing and especially keyless locks. I have the knowledge and abiltiy to help you compare and decide if the AP501 is right for your needs. Do not he
