    Rated 5 out of 5 by from PERFECT Needed to change the locks at my newly purchased condo and the previous owner had changed the front door lock with a Kwikset with Smartkey, so it was a no-brainier to purchase this for my garage door entry so I could re-key both locks with the same key and thereby rendering previous keys for the front door obsolete. PERFECT!

    Can I get a new key cartridge for my Antique Brass 660 Single Cylinder deadbolt? I have this deadbolt on two doors and no keys.

    Asked by: Big Steve
    Hello Big Steve, Thank you for your interest in Kwikset model # 660 5. To replace lost keys, you can have another Kwikset keys randomly cut. Take the cylinder out of the unit and have the lock department at your local home improvement store use the resetting cradle to read the newly cut key to your lock. If the lock you have is Kwikset model #660 5 a traditional pin and tumbler, you would need to take it to a professional to have it re-keyed. Sincerely, Kwikset Support Team
