If you're handy, you can install or replace a deadbolt yourself and lock in significant savings on installation costs. Or you can hire a professional to do the installation for you. Here’s a look at how much it costs to install or replace a deadbolt.

Can You Install a Deadbolt Yourself?

Installing a deadbolt yourself is simple, provided your door isn't made of steel. Check out the link above for the full step-by-step installation instructions. Here’s a quick overview:

  1. Use the template from the manufacturer to mark the appropriate reference points on the door. Keep in mind that a deadbolt should sit roughly six inches above your doorknob.
  2. Cut the holes you've marked on the face of the door with a hole saw.
  3. On the side of the door, use a drill to make a hole for the deadbolt latch.
  4. Using a wood chisel, create an indent on the edge of the door for the faceplate. Drill pilot holes for the screws, then install the faceplate.
  5. Install the deadbolt mechanism and fasten it in place using screws.

Replacing a deadbolt is even easier because the framework is already laid out for you. All you need is your new deadbolt, a screwdriver and some screws.

How Much Does a Deadbolt Installation Cost?

According to those in the locksmith industry, deadbolts are extremely affordable considering the high level of protection they add to your home. Professional locksmiths can install a deadbolt for you within a couple of hours. However, you'll pay a higher price than if you just purchase the parts and install it yourself.

A deadbolt from Walmart costs roughly $15 to $30, though you may pay more depending on what type of deadbolt you want and where you purchase it. This is a nominal fee for a heavy-duty lock, especially if you already own the necessary tools. If you need professional installation, a locksmith's services (based on the national average) can range from $65 to $145 per door, depending on the material of the door and where you live. Keep in mind that, on top of the labor costs, most locksmiths also charge a service fee just for coming out to your house. Usually, it’s around $25.

How Much Does It Cost to Replace a Deadbolt?

But what if you only need to replace the deadbolt? The holes are already drilled, so replacing a deadbolt yourself is easy — just buy a new deadbolt and put it in according to the manufacturer’s instructions.

Hiring a locksmith to come out and perform the swap for you can cost anywhere from $100 to $150, including the service charge. In this case, you're paying basically the same amount that you would for an installation. Given that it's a simpler procedure than a full-blown installation, you should be able to perform the replacement yourself. It will save you a significant chunk of money.
