Mechanical keys are the simplest form of physical access control and the method many smaller organisations use. Even for a small company, however, using mechanical keys has several flaws and limitations – especially as an organisation gets bigger. Below are just some of the problems presented by using keys.
People lose keys
If someone loses a key, you need to replace the lock to make sure the lost key can’t be misused. You then need to distribute new keys to everyone who needs access to that door.
Keys don’t leave an audit trail
You can’t see if and when someone’s used a key, so you don’t know who’s entered or at what time.
Keys are difficult to manage
If someone needs to enter many different buildings and rooms, they’ll need a large number of keys, which are inconvenient to carry and use. It can be difficult to remember which key is for which door, but it’s too much of a security risk to label them.
