When it pays off
- Staff turnover is regular, and collecting keys back is a chore.
- Different people need different doors at different hours.
- You need a record of entries, for insurance, compliance or peace of mind.
- You want to unlock the front door on a schedule.

The pieces
| Part | What it does |
|---|---|
| Reader | Reads the card, fob or phone credential at the door. |
| Electric lock | An electric strike, mag lock or electrified lever that the system releases. |
| Door position switch | Tells the system if a door is propped or forced. |
| Request to exit | Lets people out freely and keeps alarms from tripping. |
| Controller and software | Holds the schedules and the log. Many systems now run in the cloud. |
Fire code still comes first
An access-controlled door must still let people out freely in an emergency. That shapes which lock goes on which door, and is one reason to have a locksmith who knows door hardware design the system rather than a box from the internet.
Questions to ask before you buy
- Is there a monthly fee, and what happens if we stop paying it?
- Can we add doors later?
- What happens in a power outage?
- Can a normal key still open the door as a backup?
