Key Profile/SystemAbloy currently has two different systems of locks the Abloy Protec2 and the Abloy Protec. First you must decide which system you would like to buy, most locks are available in both systems. For more information on the Protec1 verse the Protec2 please see our Abloy Brand Information page. To order a lock in the Abloy Protec2 you must select a key profile that has the number 2 in its name (ie "Protec2 Elite" or "Ruby2 Exclusive"). Next you have a choice of key profile, the key profile of a lock primarily is an issue of key control. 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. Having an exclusive key profile can also be useful if an eventual attack against the Abloy Protec is found. While it is hard to speak about something that has not happened, many advanced rights escalation attacks, or advanced attacks against high security locks, require having a key (or key blank) that fits the lock. With the Ruby Exclusive you will make it harder for an attacker to have access to a fitting key.
