In order for locks to be Keyed Alike they have to contain the same cylinder keyway. For instance our Schlage residential locks come stocked with the Schlage SC1 cylinder keyway, while our Kwikset residential locks come stocked with the Kwikset KW1 cylinder keyway. Schlage SC1 and Kwikset KW1 cannot be keyed alike. However, Emtek comes standard with the Schlage SC1 keyway so Emtek locks can be Keyed Alike to Schlage Locks because they both contain the same cylinder keyway. All keying charges will be applied when the appropriate key selections are made. If Keying is requested separately we will add those charges accordingly.
