Question: what kind of keyway does it have?  looking for a sc-1...
Document: I filed about 1/8" off each of the tailpieces and then the locks worked fine. I was going to contact Schlage about this problem and found a FAQ on Schlage's website confirming this problem and solution.
"Grade 1 security at Dexter prices" and definitely a bargain.As others have rightly stated, and despite the misleading stock photos, this is a Schlage B62N deadbolt, and not a SecureKey product (which would be the B62NSK model).
Specs on Schlage website says it will fit on 1-3/8" doors but not without some filing or grinding. I tried to install two of these B62 deadbolts on doors that are 1-3/8" thick and both locks would not function correctly because the tailpiece on each side was hitting the back of the cylinder on the other side. If the housing screws were tightened all the way, neither cylinder would turn. If the screws were left slightly loose than the cylinders would turn.
This lock was bought to replace an older double cylinder lock because the satin finish on the old lock was starting to show wear. This lock works. The installation was pretty simple and it covers the old lock hole.The biggest dislike for me is that if you tap the large dome around the keyway, it with you key it sounds hollow and tinny.
I ordered this based on the product number, hoping that they would be "old style" locks, not the new Securekey. (Note that the picture shows the "+" above the keyway, which indicates a Securekey lock, but that is incorrect). The product number is correct, and the lock is indeed the old style, no "+" on the face. The Antique Pewter matches my other Schlage door hardware perfectly, I couldn't be happier.
The lock operates very smoothly and the key glides in and out. I used WD-40 on the inside and powdered graphite in the key hole, but this was probably not necessary. If you are looking for a step up from the basic dead bolt, I highly recommended this. No special tools were necessary. Installation took about 20 minutes after drilling.Looks great in brass.
home) I was told "double keyed deadbolts are against code and law". I installed them anyway against the county? / state? probition. Their fear was occupants being trapped if the place was on fire. Big brother at attention still protecting me against myself..That was 3 years ago after I told the bureaucrats to stuff it. I'm still free and havent burned up yet..Double keyed deadbolts can also delay burglers from quickly removing your valuables.
You can spend almost the same amount of money if you pay a locksmith. They bring an inferior brand and add a surcharge. Do what I did .... get this brand/model. I did my research and these are rated very highly in terms of being secure. When I lock my doors at night, I hear a nice "thap" sound. Solid equipment, moves nicely. WORTH IT.Update: still loving my new locks.
While I don't have too much experience with locks, I can easily tell these are of a good quality, especially compared to the locks I replaced. The screws that secure the strike plate for this lock were easily twice the size of the ones I replaced. Installation was easy and the lock operates smoothly, absolutely no complaints!
This particular lock comes from Amazon in a builder grade, plain brown box rather than a retail box like you would find at the big box home improvement store. Consequently it rattled around in the box damaging the finish slightly. You only save a few clams buying it on Amazon vs locally, and the retail boxes better protect the finish.Hopefully this lock will last longer than the Schlage locks that were installed in my house when I bought it.
Answer: yes
