MASTER KEY SYSTEMS

We can create computer generated, multi-tier master key systems with hundred's of guaranteed changes (so one key will not accidental work a door its not supposed to work, all with in the same system)

A master key allows one key to have access to all areas and an individual key would be allowed access to individual areas only.

Example: Say you own or manage three executive buildings, all have 25 plus suites per building. We can create a master key to work all three buildings, then an individual master key for each building, then individual keys per suite.
