Cost to Install a Deadbolt
Installing a deadbolt involves laying out the lock position, drilling a main hole through the door and a latch hole in its edge, then fitting the lock and strike plate. Homeowners often take this on to replace an old unit or add a deadbolt as an upgrade. It is a moderate DIY project where accurate template marks, a steady door, and careful jamb work matter.
Common reasons homeowners do this job
- An existing deadbolt is worn or damaged.
- An old lock unit is being replaced.
- A homeowner wants to add a deadbolt to a door.
- A door-security upgrade is planned.
DIY or call a pro?
This can be a DIY project, but a professional is worth considering if measuring the door thickness and backset, drilling the door holes, or chiseling the strike area feels uncomfortable. Wear hearing protection when using a power drill and eye protection while drilling or chiseling. Clamp or otherwise hold the door steady before drilling.
Frequently asked questions
- Can I install a deadbolt myself?
- Yes. This is a moderate DIY job when the lock kit matches the door thickness and backset and the door can be held steady for drilling. Consider professional help if using a hole saw, drilling the latch hole in the door edge, or chiseling the jamb is outside your comfort level.
- What makes deadbolt installation cost more?
- The price can rise with the size of the job, including each deadbolt being installed, along with labor time and materials. Small jobs may also include a minimum or trip charge.
- What should I check before choosing a deadbolt lock kit?
- Measure the door thickness and backset first to confirm compatibility with the lock kit. The deadbolt position is typically set 6 to 12 inches above the existing doorknob, using the paper template to mark the main and latch-hole centers.
- What tools and safety gear are needed to install a deadbolt?
- The work uses a drill or impact driver, hole saw kit, spade bits, chisel, hammer, 4-in-1 screwdriver, combination square, pencil, clamps, and the lock kit's paper template. Use hearing protection for power drilling and eye protection against drilling or chiseling debris, and keep the door clamped or steady.
