Keyless entry help you maintain a secure environment and avoid the problem of lost keys and the rekeying costs found with traditional keyed locksets. Many keyless door locks are vandal- and weather-resistant and can replace a standard knob set. Mechanical models require no batteries, computer, or software. Electronic models require no wiring to install, and many allow multiered security at up to 4 levels.

Grainger has the access control locks accessories you need from proximity cards and card readers, to Wi-Fi gateways that allow you to remotely program and retrieve audit trail information from electronic locking systems.
