Restricted keyways allow you to control who has a copy of a key to each individual door or lock. They also allow you to trace any key found back to when it was issued, and to whom. You will always know how many keys are out in the world because those who were issued keys will not be able to get them copied without your permission. If a key is lost, we can make it unusable in one service call. To that end, we offer the GMS MX keyway, which saves you money over other systems, but still allows for strict control and trace of who has which keys.
