Legally the Protec Elite and Ruby Exclusive key profiles have the same level of key control, no dealer other than the dealer who originally issued the keys (or the Factory) can cut more keys. Technically, with the standard Protec Elite key profile, all Abloy Protec/Protec2 dealers in the US have access to this key blank. This is a slight security risk as it does mean they could duplicate a Protec/Protec2 Elite key if they wanted to (but they would break their contract with Abloy in doing so and we have yet to hear of a dealer doing so). Our Ruby Exclusive key profile is a key blank that is only issued to us, which removes the option for another Abloy dealer to duplicate your ruby key as they do not have access to the key blanks. A Protec Elite key will not even fit in a Ruby Exclusive lock. The Ruby Exclusive is a very secure level of key control giving peace of mind to even the most worried lock owner.
