Emtek Keyless Deadbolts do not require a key to enter, but you can use one if you wish. Keyless deadbolts are generally used in conjunction with an emtek passage door knob or lever handle on exterior doors. Keyless deadbolt locks are programmable so you can create your own custom code for locking and unlocking the door. This is a great soluction for a secure home and not worrying about losing keys.
