Antique Nickel Deadbolt
I bought this deadbolt because I needed to replace the doorknob below it and could not find the original color anywhere. I bought a new door knob in a similar color to what I already have throughout my house and bought this dead bolt to match. I was super surprised to find out that this was the exact color I had been looking for for month. So the dead bolt is not really needed as the new handle matches the old dead bolt. But I'm going to hang onto it as I feel like it's going to be needed soon. The old one is good quality and this one seems to be the same so I would definitely recommend them. Plus, this is a very classy color. If you buy this color though, be aware that you can't get a replacement anywhere else. So save this web site in case you need replacement parts!

Great quality easy to install
I had been calling around to locksmiths to get three locks in my house converted from double cylinders to single cylinder. My son-in-law recommended I get Grade 2. I did search for single cylinder locks nut it was confusing. I came across DoorLockDirect and wrote an email explaining what I wanted to do. I got a prompt answer and I bought the locks. The locks installed in under 5 minutes each. I saved a bunch of money and also git the quality and brand I was looking for. Highly recommend Doorlockdirect.
