Deadbolt Installation
New deadbolts fitted to exterior doors, including fresh bore-outs, strike reinforcement and matching keys.
Short answer: A deadbolt adds a solid bolt that cannot be slipped like a spring latch. Installation covers a fresh bore in the door if there is none, a reinforced strike in the frame, and keying the new lock to match your existing key where possible.
Choosing the right deadbolt
Look for a bolt that throws a full inch, a hardened insert against sawing, and a Grade 1 or Grade 2 rating. Single-cylinder is standard; double-cylinder (key both sides) suits doors with glass nearby but must be used with care as an exit. Keypad and smart deadbolts are covered under smart lock installation.
Installation details that matter
The strike plate is where most doors fail. A four-screw box strike with 3-inch screws into the stud turns a kick-in from a one-hit job into a long, noisy one. Bore alignment, a properly sized backset and a bolt that throws freely without lifting the door are all checked before the job is signed off.
What it typically costs
Typical installed cost is $100 to $250 for a standard deadbolt including hardware, with a fresh bore-out or a high-security cylinder adding to that. Ask for the total with the lock you want.
Every job is quoted as a total, on the phone or before work starts on site. Ask for it, and see the full pricing guide for what drives the number.

Can a deadbolt be installed on a door that never had one?
Yes. The door and frame are bored to standard dimensions with a jig, and a reinforced strike is fitted.
Can the new deadbolt use my existing key?
In most cases, when the new cylinder shares a keyway with your current lock or a matching cylinder is fitted.
What deadbolt grade should I buy?
Grade 1 is the strongest, Grade 2 is solid for most homes. Avoid unrated bargain locks; the strike reinforcement matters as much as the lock.
