And if you’d rather skip the tools and get it done fast our local locksmiths in Coarsegold can handle everything for you.

Why a Deadbolt Lock Matters

A regular spring bolt lock can be forced open with a credit card or a bit of pressure but a deadbolt can’t be moved without the right key. It’s built for security. That’s why every good locksmith will tell you: if you care about protecting your home, start with your door.

Deadbolts make it much harder for intruders to break in and give you that peace of mind when you lock up at night.

What You’ll Need

Before you start, gather these tools and supplies. Most come in an installation kit, or you may already have them at home.

Tools

• Power drill

• 1-inch spade bit

• 2⅛-inch hole saw

• Chisel

• Tape measure

• Screwdriver

• Pencil or marker

• Lubricant (optional, for smooth operation)
  

Supplies

• A quality deadbolt lock

• Screws and strike plate (usually included)

• Paper template (included with most locks)

Step-by-Step: How to Install a Deadbolt Lock

1. Remove the Old Lock (if you have one)

Start by unscrewing and removing your old deadbolt. Take off both the inside and outside plates, then pull out the latch. This gives you a clean, open space for your new lock.

2. Mark the Placement

Decide where your new lock should go typically about 6 to 12 inches above your door handle. Use a pencil to mark the height and line it up straight. If you’re replacing an old lock, you can skip this part and just reuse the same position.

3. Use the Paper Template

Your lock should come with a paper guide. Tape it to the door at the height you marked. It’ll show you exactly where to drill the holes, one through the door face and one on the door edge.Taking the time to align this correctly makes everything easier later.

4. Drill the Main Hole

Using your 2⅛-inch hole saw, drill the hole for the lock cylinder straight through the door. To avoid splintering, drill halfway from one side, then finish from the other. Keep it steady  this is where accuracy really matters.

5. Drill the Latch Hole

Next, drill a 1-inch hole on the door’s edge where the latch will fit. Check that it connects neatly to your main hole. You can clean up the edges with a chisel if needed.

6. Install the Latch and Faceplate

Slide the latch into the edge hole and trace around the faceplate with your pencil. Then, chisel out a shallow recess so the faceplate sits flush with the door edge. Once it’s even, secure it with screws.

7. Fit the Deadbolt Mechanism

Push the deadbolt through the large hole so it connects with the latch. Add the inside and outside plates, making sure everything lines up smoothly. Tighten the screws not too much, just enough to hold everything firm. Turn the thumb latch or key to check that it moves freely.

8. Install the Strike Plate

Now move to the door frame. Close the door, mark where the latch hits, and use that as a guide for your strike plate. Drill small pilot holes and chisel a shallow groove so the plate sits flat. Use long screws (2½–3 inches) to secure it  and anchor it into the frame for stronger protection.

9. Test the Lock

Before calling it done, open and close the door a few times. Make sure the bolt slides easily in and out of the strike plate. If it sticks, adjust the plate slightly until it works smoothly.

10. Add the Finishing Touches

Wipe away dust, add a little lubricant if needed, and double-check your key. That’s it you just installed your own deadbolt!

Different Types of Deadbolts

Not all deadbolts are the same. Here’s a quick look at your options:

• Single-cylinder – Key on the outside, thumb turn on the inside. Most common and easy to use.

• Double-cylinder – Key on both sides; great for doors with glass panels but keep a key nearby for emergencies.

• Vertical deadbolt – Stronger and more secure, often used for extra reinforcement.

• Smart deadbolt – Keyless, app-controlled, and perfect for modern homes that want extra convenience.

DIY vs. Hiring a Locksmith

You can definitely install a deadbolt yourself if you’re comfortable with basic tools. It’s cheaper (about $25–$200 for the lock). But if you want it perfectly aligned and installed fast, hiring a pro saves you time and gives you peace of mind.

At Super Locksmith of Coarsegold, we handle deadbolt installation, lock repair, rekeying, and smart lock upgrades for homeowners who want reliable security done right. Our licensed locksmiths make sure everything fits perfectly, no gaps, no jams, no stress.

Cost to Install a Deadbolt Lock

Here’s a general idea of what to expect:

• DIY install: $25–$200 (depending on the lock)

• Professional install: $75–$300 (including labor)

• Smart deadbolt setup: $150–$400

The extra cost for a pro often pays off with a secure fit and longer lock life.

Common Questions

Can I install a deadbolt myself? Yes, just follow the steps above carefully. If drilling and chiseling sound tricky, it’s safer to let a locksmith handle it.

Can I install a deadbolt on any door? Most wooden or metal doors can handle a deadbolt, though hollow doors might need reinforcement.

Are smart deadbolts worth it? Absolutely. They offer convenience, keyless entry, and remote access perfect for families or anyone who forgets their keys.
