I built my new house 14 yrs ago and only bought a new lock to replace the old one because the latch was failing on the old lock. Will get a replacement latch fir the old handle and put it on a door we added to the porch. The old lock was very heavily used. That is the door my husband uses to smoke on the front porch and for the four dogs going in and out. It is opened at least 50 times a day or more. Has truly been a awesome lock. Easy to have rekeyed to fit the key I have for all my locks, including garage. My husband ran a locksmith shop for over 15 yrs and will only use Schlage locks.
