Question: What tool is used for securing the two bolts that hold the front and back pieces of the lock together? I have 100s of bits and none fit.
Document: 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.
I bought this lock for more security for the basement door due to a burglary. The lock was a good replacement for the cheaper Defiant single key lock. The core of the two locks are connected in a steel cylinder cover and it reinforces the overall mechanism with a thicker and longer strike bolt. I had to mortise out the door a little more for the strike-plate, but it fit perfectly in the old place. The advantage here is a reinforced strike-plate, too.
Actually I bought these to replace my old locks because I have windows on both sides of my front and back doors. A thief would only need to smash a 6" window and flip the old thumb lever to gain access inside. They're simple to install if you can operate a Phillips screw driver. They took a little jiggling and adjusting to work as designed.
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.
I wanted a deadbolt that was keyed on two sides, and actually had a tough time locating one in my local hardware and big box stores! This is exactly right, and I can install myself, and have BETTER security and save the cost of hiring a locksmith provide the lock and charge for the installation! (If you do not have the correct bit, you will have to purchase one in order to do this yourself) I am VERY pleased!
For security reasons, I decided to change out our one key deadbolts for two keyed ones. They were easy, it seems, to be switched out with our Quick Set ones; however, I wasn't aware that we could not have a Quick Set lock and a Schlage lock keyed to the same key. So now I have to use two keys on my doors which is a pain! I guess I'll have to replace the door handle locks with Schlage  as well.
I ordered two of these plus a single keyed deadbolt from Amazon. When you turn the key, the lock feels very sturdy. Unfortunately, I could not figure out how to order matching keyed locks from Amazon - I ended up taking two out of my three locks to ACE hardware to have them rekeyed. $7 x 4 cylinders = $28 extra to get these rekeyed. I would recommend picking up a re-keying kit on amazon while you are at it.
The finish looks great (matches other products very well). Very sturdy deadbolt, double-side key lock is great for those with little ones who like to unlock doors or for extra security if you have windows on sides of your front door.
I needed to get a deadbolt with keyed inside and out to make sure my elderly mom did not just walk out of the house without my knowing, this fit the bill. Surprisingly, this is difficult to find.
If you want good security this is itStrong, weather resistant and reliable. Used by home owners and pros  alike
