What a Pro Handles for Deadbolt Locks
A licensed locksmith covers every deadbolt job, including:
- New installation on doors that only have a knob or lever latch
- Replacement of worn, damaged, or low-grade hardware
- Repair when the bolt sticks, the cylinder is loose, or the lock won't turn
- Rekeying so old keys no longer work without replacing the entire lock body
- Emergency lockout if you're locked out and need the door opened without damage
For emergency lockout help, a licensed pro can typically reach you in under an hour.
Signs Your Deadbolt Needs Attention
If any of these apply, it's time to call a locksmith:
- The bolt doesn't extend or retract smoothly
- The cylinder spins or feels loose in the door
- You just moved into a home and don't know who has copies of the existing key
- Your keys were lost or stolen
- The lock is visibly corroded or the finish is cracked
- The bolt no longer lines up with the strike plate hole in the frame
A lock that binds or sticks isn't just an inconvenience. It's a security gap that also delays your exit in an emergency.
What to Expect During the Job
A straightforward deadbolt installation on a pre-bored door typically takes 30 to 60 minutes. A new bore adds time and requires a hole saw and chisel work for the strike plate mortise. Your locksmith will:
- Measure the door thickness, backset distance, and existing bore size
- Select or confirm the correct deadbolt for your door prep
- Install the lock body and cylinder
- Seat and secure the strike plate with long screws into the door frame stud
- Test the bolt throw, cylinder turn, and thumb-turn action before leaving
Repair visits follow the same pattern: diagnose why the bolt is binding, adjust or replace the part, and test.
What Affects the Cost
Several factors move the final price:
- Lock grade: Grade 1 hardware costs more than builder-grade but lasts far longer
- Lock type: Smart deadbolts with wireless connectivity cost more than mechanical ones
- Cylinder type: High-security cylinders with bump and pick resistance carry a premium
- New bore vs. existing prep: Cutting a new hole in a solid-core door takes more time
- Labor rates: Vary by region and whether the job is same-day or after hours
ANSI Security Grades: The One Detail Most Pages Skip
Every deadbolt sold in the US is tested under ANSI/BHMA standards and assigned a grade:
- Grade 1: Survives 250,000 open-close cycles and withstands a 360-pound single-blow impact. This is the minimum for a front door, back door, or garage entry.
- Grade 2: Rated for 150,000 cycles and a 250-pound impact. Fine for interior or secondary entries where security risk is lower.
- Grade 3: Builder-grade. Rated for 75,000 cycles. Common in new construction because it's cheap, not because it's secure. Replace it.
Strike plate matters as much as the lock. A Grade 1 deadbolt with short screws can still be kicked in because those screws only grip the door casing. Have your locksmith use a reinforced strike plate with 3-inch screws that anchor into the rough frame. This single step dramatically improves kick-in resistance at minimal cost.
For pick and bump resistance, ask for a Grade 1 model with anti-pick pins and an anti-drill hardened steel plate around the cylinder.
FAQ
What is the difference between a single and double cylinder deadbolt?
A single cylinder deadbolt uses a key outside and a thumb-turn inside. A double cylinder requires a key on both sides, which limits entry through a nearby broken glass panel. Check local fire codes before choosing one, because they slow exit in an emergency.
How much does deadbolt lock installation cost?
Cost depends on the lock grade, whether a new bore is needed, and local labor rates. A local locksmith quote is the only reliable number.
Can I install a deadbolt myself?
You can if you're precise with a drill and chisel. Any misalignment leaves the bolt binding or the cylinder loose. A licensed locksmith finishes the work in under an hour and gets alignment right the first time.
What ANSI grade deadbolt is recommended for a front door?
Grade 1. It handles significantly more stress cycles and impact force than Grades 2 or 3. Front and back entry doors should both have Grade 1 hardware.
Can a deadbolt be picked or bumped?
Standard deadbolts are vulnerable to bump keys and pick tools. Grade 1 deadbolts with anti-pick and anti-bump pin configurations are much harder to defeat.

FAQ & Access Control Guidelines
Q:What is the difference between a single cylinder and double cylinder deadbolt?
A single cylinder deadbolt uses a key on the outside and a thumb-turn knob on the inside. A double cylinder requires a key on both sides. Double cylinders add security against break-ins near glass panels but can slow exit during a fire, so check local fire codes before installing one.
Q:How much does it cost to install a deadbolt lock?
Cost depends on the lock grade you choose, whether it replaces an existing lock or requires new boring, and the labor rate in your area. Mechanical Grade 1 locks cost more than builder-grade hardware; smart deadbolts add to the price. Get a quote before committing.
Q:Can I install a deadbolt lock myself?
You can if you're comfortable drilling a door bore and chiseling a strike plate mortise with precision. Any misalignment will leave the bolt binding or the lock rattling loose. A licensed locksmith finishes the job in under an hour and aligns everything correctly the first time.
Q:What ANSI grade deadbolt should I buy?
Grade 1 is the top residential pick and handles far more test cycles than Grades 2 or 3. Grade 2 works fine for interior or secondary doors. Builder-grade (Grade 3) locks are usually replaced within a few years. For a front or back entry door, go Grade 1.
Q:Can a deadbolt be picked or bumped?
Standard pin-tumbler deadbolts are vulnerable to bump keys and basic picking. High-security deadbolts with anti-pick pins, anti-bump spring-loaded pins, and hardened steel inserts are significantly harder to defeat. Ask your locksmith about ANSI Grade 1 models with pick and bump resistance built in.
