At Okey Locksmith, we strongly believe that you should never pass up an opportunity to make your home safer. One of the easiest and most straightforward ways to improve your house's security is to install a deadbolt lock. If you're considering doing so, we're here to walk you through the main things you should know about deadbolt locks, including the different types and the deadbolt installation process. Let's start!

Why Install a Deadbolt Lock?

Unlike regular doorknob locks, deadbolts are generally considered to be more secure. They usually require a key to open from the outside and a turn of a knob or key from the inside, meaning they can't be easily picked or bumped like other locking mechanism types. With a new deadbolt lock, you can be at peace knowing that your home is extra secure.

Different Types of Deadbolts

1. Single Cylinder Deadbolts

This type is locked or unlocked with a key on the exterior door, and there's a twist knob on the interior side. It's great for doors without glass panels to prevent forced entry, as an intruder can potentially smash the glass and reach through to unlock the door from the inside. We recommend it you have a wooden or steel door.

2. Double Cylinder Deadbolts

Unlike single-cylinder deadbolts, a double-cylinder deadbolt requires a key to unlock it from the interior and exterior sides. This type of deadbolt lock can work for doors with glass panels or doors near windows, so that even if a burglar breaks a portion of the glass, they still can't unlock the door without the key.

3. Keyless Deadbolts

Keyless deadbolts, as the name suggests, don't require keys at all and can be unlocked through other means like a fingerprint, keypad, or a phone. It's a convenient option, especially if you're the type of person to lose your keys or if you have multiple people who need access to your home.

A Quick Reminder

The right tools will still depend on your door material. So, make sure you know the material you'll be working with (e.g. wood, steel, or fiberglass) and purchase the tools accordingly.

This installation guide is a general outline of the steps of a deadbolt installation, but the process may still be different depending on the kind of deadbolt lock model you've got. It's still best to have the manufacturer's instructions ready and use it alongside our guide.

Remove the Existing Deadbolt (If Applicable)

Before you can begin installing a new deadbolt lock, remove the existing one first. Start by removing all the screws attaching the old deadbolt lock to the door. Remove the strike plate and the rest of the lock assembly.

Then, clean out the mortise (the hole in the door where the lock mechanism fits) if you find any dirt or debris. Check if the existing hole is the right size for your new deadbolt. If not, you'll have to make some adjustments using a drill or chisel; it depends on how big of an adjustment it is.

Once the adjustments have been made, or if the existing hole doesn't need any changes in the first place, you can proceed to Step 3.

Step 1: Choose the Right Height for the Deadbolt Location

You'll want to install your deadbolt lock about 6–12 inches above your doorknob. Measure carefully, and then hold the deadbolt template that comes with your kit against the door at the chosen height. Mark where the holes need to be drilled. While marking this spot, make sure it aligns well with the sturdy part of your door jamb and door frame.

Step 2: Drill Holes

Now, you need to drill a hole for the deadbolt lock assembly. You can use a hole saw to cut through the door face for the deadbolt lock, and then use a smaller bit for the hole on the door edge, which will serve as the bolt hole.

Before inserting screws into any part of the lock, drill pilot holes to make the process smoother and to prevent splintering wood.

Step 3: Chisel Out the Mortise

Depending on your deadbolt lock model, you might need to chisel out a small area on the edge of the door so that the strike plate sits flush with the door edge.

Step 4: Install the Bolt

Now, it's time to install the lock body and the deadbolt plate. Fit the bolt into the edge hole and use the provided screws to secure it in place.

Step 5: Attach the Deadbolt Lock

Line up the outer and inner parts of the deadbolt through the holes in the door face. Connect them as directed in your installation kit and screw them together tightly. Make sure the bolt extends and retracts properly, and that the key turns easily in the lock.

Tips to Remember After You Install a Deadbolt Lock

Lubricate the Lock – Every so often, a small amount of lubrication can keep the mechanism running properly and help with smooth operation.
Check the Scews – Check the screws, especially those on the exterior doors. Tighten them up right away if they feel loose
Don't Forget to Duplicate Keys! – Always go to trusted professionals for key copies. Trust us, you'll thank yourself in the future!
