Master key systems serve a critical role in your overall integrated security approach. It is our belief that one product cannot fully and effectively secure your building, assets and employees. Your master key system is often the first line of defense against unauthorized entry. We work exclusively with Abloy to provide the most secure and strictly controlled key system in the world. With over 1.97 billion possible key combinations, we have the flexibility to design a simple system from a few locks to a national facility-wide master key system, spanning across all of your facilities. Abloy's unique rotating disc system within their locks significantly reduces susceptibility to attack by bumping or lock picking, ensuring a high level of security.
