Deadbolt Locksmith Service, Done Right the First Time

A deadbolt locksmith installs, rekeys, and repairs the lock that does the real work of keeping your door closed: the deadbolt itself. It's one of the most common calls inside residential locksmith service, and most jobs finish in a single visit. If your current deadbolt sticks, won't turn, or came with a house you just bought, a same-day fix is realistic.

What a Deadbolt Locksmith Handles

A locksmith handling deadbolts typically covers:

• New installs on doors with only a doorknob lock
• Swaps for a worn or damaged deadbolt
• Rekeys so old keys stop working, no new hardware needed
• Repairs for a bolt that sticks, binds, or won't fully throw
• Upgrades to keypad, electronic, or smart deadbolts
• Strike plate and door frame reinforcement

A deadbolt is only as strong as the frame it's set into.

Signs You Need a Deadbolt Locksmith Now

Some deadbolt problems are obvious; others build slowly until the lock fails. Watch for:

• The bolt sticks, needs a hard shove to throw, or doesn't fully extend
• The key is hard to turn, insert, or remove
• The deadbolt is loose or wobbles, with gaps around the strike plate
• You moved in and don't know who else has keys, or it's a basic Grade 3 lock
• A break-in attempt left pry marks or a bent bolt

Any of these is reason enough to call, and often it's just a loose strike plate, fixed in minutes.

Types of Deadbolts a Locksmith Installs

Single Cylinder Deadbolts

A key outside, a thumbturn inside. The standard choice for most exterior doors, and the simplest to install, rekey, or service.

Double Cylinder Deadbolts

Needs a key on both sides, including from inside. Useful near glass panels where someone could reach through and turn a thumbturn, but some fire codes restrict these on exit doors.

Electronic, Keypad & Smart Deadbolts

Skips the physical key and lets you issue temporary codes instead. Most still keep a mechanical backup key, and installation includes programming, not just mounting hardware.

Deadbolt Security Grades Explained

Deadbolts are graded 1 through 3 under the ANSI/BHMA A156.36 standard, based on how much force the lock survives, not how it looks.

Grade	Strike Test	Cycle Test	Best Fit
Grade 1	Withstands 10 strikes at 75 ft-lbs	250,000+ cycles	Ground-floor entries, rentals, high-risk doors
Grade 2	Withstands 5 strikes at 75 ft-lbs	150,000 cycles	Most standard front and back doors
Grade 3	No formal strike requirement	100,000 cycles	Interior doors, low-risk entries

Grade 1 costs more, but on an exterior door, it's usually worth the difference.

Rekey or Replace? A Quick Decision Guide

Not every deadbolt problem means new hardware. Use this as a starting point, then let the locksmith confirm in person.

Rekey when:

• The deadbolt is Grade 1 or 2 and still turns and throws smoothly
• You just moved in and the hardware is in good shape
• You only need new keys, not different hardware

Replace when:

• The deadbolt is Grade 3, more than 15 to 20 years old, or the bolt is bent or pitted
• The strike plate or door frame is cracked, stripped, or pulled loose
• You want to move up to a keypad or smart deadbolt
• The cylinder is too worn to accept new pins during a rekey

How Deadbolt Installation & Repair Works

A standard install or swap runs 15 to 30 minutes per lock, longer with first-time boring or frame reinforcement. Expect:

1. A quick check of the door, frame, and existing hardware
2. Removal of the old lock, or boring new holes if there's no deadbolt yet
3. Installing and aligning the new deadbolt and strike plate, then testing the bolt throw and key operation
4. Rekeying on request so every lock on the door matches one key

What Affects Deadbolt Locksmith Cost

Pricing depends on a handful of factors, not a flat rate:

• Lock grade and type. Basic Grade 2 costs less than Grade 1 or a smart deadbolt with keypad and app features.
• New install versus rekey. Boring a door for a first deadbolt takes longer than rekeying one already there.
• Number of locks and door condition. Keying every door to one key is often cheaper per lock; a damaged frame needing reinforcement adds labor.
• Timing. After-hours or emergency calls commonly carry a premium over a scheduled daytime visit.
• Service call fee. Most locksmiths charge a minimum trip fee, separate from parts and labor.

Nationally, a single deadbolt install or swap commonly runs $70 to $300 including labor, more for a higher-grade or smart lock. Ask for the service call fee and labor rate upfront, and ask your insurer whether a security upgrade qualifies for a discount.

Frequently Asked Questions

How much does it cost to install a deadbolt?

It depends on lock grade, install versus rekey, and local labor rates, but expect roughly $70 to $300 per lock, more for high-security or smart deadbolts, plus any minimum service call fee.

What's the difference between single and double cylinder deadbolts?

A single cylinder uses a key outside, a thumbturn inside. A double cylinder needs a key on both sides, adding security near glass panels but slowing an emergency exit, so check fire code first.

Is a strike plate necessary for a deadbolt?

Yes. It's what the bolt actually locks into, and a flimsy plate with short screws is a common reason deadbolts fail in a break-in. A reinforced plate needs screws long enough to reach the door framing, not just the jamb.

Can a burglar pick or force open a deadbolt lock?

Any lock can be defeated given enough time, but a Grade 1 deadbolt takes far longer to force or pick than a Grade 3 lock, and paired with a reinforced strike plate it's one of the best upgrades for the cost.

Do locksmiths rekey deadbolts, or only replace them?

Both. Rekeying swaps the pins inside the existing cylinder so old keys stop working, without replacing the lock. It's faster and cheaper when the hardware is still in good shape, such as after a move-in or a lost key.

How long does deadbolt installation take?

A single lock typically takes 15 to 30 minutes on site, longer with first-time boring or several locks to rekey.

A deadbolt is one lock, but it does the most work on your door, so getting it right the first time beats a repeat call later. For general door lock repair beyond the deadbolt, a licensed locksmith can usually be there the same day. Call a licensed local locksmith now for a fast quote.
