My wife’s key fob broke and we were calling around and these little hustlers in their portable key trucks were trying to charge her $150 then when we said no thank you ,,they would call us back and ask how much are you willing to pay?

Appreciated how quickly he was able to help, and was also a very nice guy.

Vincent and Weston are the best employees ever! Vincent has been helping me with keys since 2011. I had three keys that did not work but they did not hesitate to make it right for me. Their warranty here is amazing. I only get my keys here at DUP-A-KEY. Very reliable and affordable, definitely recommend!
