Lock Replacement and Installation in New Jersey
Properly graded hardware, installed right. Get the price before anyone drives out.
Three Things to Know
- Worn or Damaged Lock Replacement
Hardware that no longer functions properly is removed and a graded replacement installed that fits your door without forcing it.
- Builder-Grade Upgrade
Basic locksets installed during construction can be swapped for higher-security ANSI Grade 1 or Grade 2 hardware.
- New Door Lock Installation
New doors, or doors that have never had a lockset, can be bored, prepped, and fitted with hardware, including handle, deadbolt, and strike plate.
The Guide
Builder-grade locks fail. Old hardware wears out. Sometimes a break-in attempt leaves a lock that looks fine but no longer functions the way it should. When a lock needs to come off the door entirely, properly graded replacement hardware should go on in its place, installed the right way.
When Rekeying Is Not Enough
Rekeying changes who can open a lock. It does nothing about what the lock is made of or how well it holds up under pressure. Hardware fails in ways that rekeying can’t fix: internal mechanisms that grind, bolts that don’t extend fully, cylinders that wobble in their housing, strike plates that have pulled away from the frame.
A lock that’s been pried, kicked, or hammered during a break-in attempt may look operational but have internal damage that compromises the mechanism. This is common: the door closes, the bolt throws, but the cylinder shifts slightly when you turn the key. That’s a lock that should come off the door.
Builder-grade locks, the hardware installed during construction to get a certificate of occupancy, are typically Grade 3 ANSI rated. They’re fine for interior closets. On an exterior entry door in a New Jersey home, they’re the minimum possible standard. Upgrading to a Grade 1 deadbolt is one of the most cost-effective security improvements a homeowner can make.
Replacement hardware should be brought to the job, with the price, including parts, confirmed before any work begins. Nothing should change on arrival.
Common Hardware and What Installation Involves
Schlage, Kwikset, and several mid- to upper-range residential brands are commonly stocked in finishes like satin nickel, matte black, and oil-rubbed bronze, covering keyed-entry knobsets, lever handles, single-cylinder deadbolts, and double-cylinder deadbolts.
A proper installation is more than swapping the lock body:
- Door alignment gets checked first, since a door that’s sagging or racked puts uneven stress on a new lock and wears it faster.
- The existing bore size, the strike plate position, and whether the frame is solid enough to accept longer screws should all be checked.
- The strike plate gets replaced if the existing one is undersized or poorly anchored.
- A properly set 3-inch screw into the door stud behind the frame belongs on every exterior installation.
What You Can Expect on the Day
The hardware being brought should be confirmed when you submit a request, so there are no surprises. On arrival, the old lock comes off, the door prep gets inspected, and the replacement goes in. The deadbolt throw, the latch spring, and the key operation should all be tested before anything is reassembled. Expect the new keys handed over, the lock’s features explained if there are any, and the door left operating cleanly.
The receipt should itemize parts and labor separately, so you know exactly what you paid for each. Request a locksmith to get a flat quote. Requests are routed to locksmiths covering every county in New Jersey.

Weighing the Options
Replacing vs Rekeying
Full replacement
- New hardware, new grade
The moment to move from Grade 3 builder hardware to Grade 1.
- Fixes wear for good
Sticking latches and worn keyways do not come back.
- $100 to $200 installed
Knobsets at the low end, deadbolts at the top.
Rekeying instead
- Sound hardware qualifies
If the lock works cleanly, rekeying delivers the same security reset.
- Costs less than half
Per-lock rekeying runs $40 to $85.
- No parts to wait on
Rekeying needs pin kits, not hardware orders.

Residential Questions, Answered
Frequently Asked Questions
How much does lock replacement cost in New Jersey?
Replacing a standard deadbolt, parts and labor together, typically runs $120 to $200. A knobset or lever handle replacement is usually $100 to $180. Higher-security brands like Medeco or Mul-T-Lock cost more. Ask for a flat price including hardware before any work begins.
Does the hardware need to be purchased separately, or is it brought to the job?
A range of residential hardware is typically stocked and brought to the job. Mention a specific brand or finish when you submit a request to confirm availability. If you've already purchased a lock, it can be installed for a labor-only charge.
Can a lock be replaced without damaging the door?
In most cases, yes. Standard residential doors have consistent bore sizes, so a replacement lock fits the existing cutouts. On older doors with non-standard prep, the bore may need adjusting, which should be discussed with you first.
What's an ANSI grade and does it matter?
ANSI grades rate lock durability and resistance to forced entry. Grade 1 is the highest residential rating, Grade 2 is mid-range. Many homes ship with Grade 3 hardware. The grade being installed, and why, should always be part of the conversation.
What if the door frame is also damaged?
The strike plate and frame area should be checked as part of the installation. A reinforced strike plate with 3-inch screws into the stud is a common recommended addition. Major frame damage may need a carpenter, and you should be told clearly if that's the case.
How long does a lock replacement take?
A single lock replacement, hardware swap with no boring required, takes 20 to 40 minutes. A full exterior door set with deadbolt, knobset, and new strike plate hardware runs 45 to 75 minutes.
