Double Cylinder Deadbolt Installation Guide

Be it single cylinder deadbolt or double cylinder deadbolt, the installation process is almost the same. Check the following steps to install  double cylinder deadbolts on your doors.

• The door you want to install the deadbolt on should have pre-drilled holes. If not, use a drill to make a hole for the deadbolt assembly.
• Place the deadbolt against the door with the latch on and measure its depth. Also, mark the faceplate area on the door edge with a pencil.
• Use a chisel to carve the wood to make space for the faceplate. Before installing, check whether the faceplate stays flush when the deadbolt is locked.
• Now, place the exterior part of the deadbolt on the exterior surface of the door. Insert the bolt assembly into the hole. Turn the key to lock the deadbolt and test whether it works properly.
• If it works fine, insert the interior part of the deadbolt on the interior side. Make sure the cylinder slot of the exterior part enters the cylinder slot of the interior part.
• Once everything is in position, use a screwdriver to attach two parts with the provided screws.
• Check how the deadbolt functions, and you are good to go.

Double Cylinder Deadbolt Removal Guide

If you are installing a deadbolt, there will come a time when you will have to remove it as well. If you have the tools, you should not call the locksmith for this job.

First of all, you have to unscrew the screws exposed outside. You can have screws on the cylinder case and the strike plate. Unscrewing them and the faceplate afterward will loosen the deadbolt and the cylinder case. 

Inside the cylinder case, there could be more screws that you have to unscrew to get the whole lockout. However, things get complicated when there aren’t any screws outside the cylinder case. 

Then you have to get some allen wrenches after getting the faceplate out. There should be two holes around the deadbolt. If you stick your allen wrench inside, you will feel it looking into something. Then turn left, and that will loosen the two cylinder cases.

You may also find screws inside that help to get the lock out completely. This process helps to secure the door from inside.

Best Double Cylinder Deadbolt Buying Guide

As almost all deadbolts have a similar design, it is difficult to determine which lock will be better for the safety of your home. We will mention several factors to consider before buying the best double cylinder deadbolt. Check them out.

Safety

Deadbolts are there for safety. If anyone can easily pick or pry open them, there is no point in installing the locks. So, you need to check the safety standard of the lock before buying.

Most quality locks are of ANSI grade-3 to prevent intruders from entering your property. The locks should withstand hard hits and be durable for a long time without compromising safety.

Material and Build Quality

Be it a single or double cylinder deadbolt, it should be made of hardened steel or brass to throw some serious hurdle to strangers. Most high-quality deadbolts are made of brass cylinders.

The cylinder cover can be made of brass or stainless steel. And the latch is also commonly made of stainless steel or brass. Every part of deadbolts should be durable.

Design and Finish

This goes down to one’s preference. You can install a deadbolt depending on the overall design of your house and doors. These locks are commonly available in black, satin, and bronze finish.

The shape of the deadbolt lock types can also be different. You need to pick one that goes with the style you want to incorporate in your home.

Functionality

No matter what deadbolt you choose, it should lock and unlock smoothly. The keyhole needs to be designed in a way so that you can easily insert the key without bumping.

Some locks tend to go loose after some time of use. Be aware of these locks.

Price

It depends on the brand value and overall quality of the deadbolt. Brass-made deadbolts will be pricier than stainless steel deadbolts. We think you shouldn’t consider price over safety in this case. Spend some extra on a deadbolt that will ensure the best security of your home.

But don’t go for excessively priced deadbolts for interior doors.
