Locks, Readers & Request-to-Exit Explained
Access-controlled openings usually combine an authenticator, a locking device and a free-egress path. These three product families solve different parts of that stack.
Electronic pushbutton & keypad locks
Electronic pushbutton locks are complete locksets mounted in the door — mechanical Simplex-style combination locks and electronic lines (PowerPlex, Trilogy, Codelocks) with scheduling or credentials. Filter pushbutton, self-powered, cylindrical and mortise.
Keypads, readers & credentials
Keypads & readers sit on the wall or mullion and control a separate electric strike, maglock or electrified lockset. Shop keypads, RFID / proximity and biometric readers, then order matching credentials & cards (cards and fobs are rarely included with the reader).
Request-to-exit (REX)
Request-to-exit switches release the lock from the secure side without a credential so egress remains code-compliant. Filter request to exit and pair with actuators when the opening is automatic.
When to use which

|---|---|
| Standalone door, minimal wiring | Pushbutton / electronic lockset |
| Central panel, many doors, shared credentials | Readers + credentials + electrified locking |
| Access-controlled egress opening | REX (and/or free-egress hardware) required |
| Automatic / ADA operator | Actuator + sensors + REX as specified |
