9 Things New Jersey Locksmiths Wish Homeowners Knew
Could you tell a state-licensed New Jersey locksmith from someone who just showed up with a toolbox?
New Jersey licenses and regulates locksmiths through a state board many homeowners have never heard of.
These are the things New Jersey locksmiths wish homeowners knew.
Note: This is general information, not legal advice. Licensing rules and legal requirements are subject to change, so confirm current details with the New Jersey Division of Consumer Affairs.
1. Installing a New Lock Yourself
Locksmiths deal with a myth almost every week.
Homeowners assume swapping a lock always requires a license.
It doesn’t.
New Jersey’s rules for what counts as locksmithing work carve out one exception.
Installing a brand-new, factory-made lock set into a door for a resident doesn’t require a license.
A homeowner, or a handyman, can legally install a new deadbolt on a front door without ever calling a locksmith.
Once that same lock needs rekeying, recombining, or repair instead of a straight swap, the work crosses back into licensed territory.
Only a state-credentialed locksmith can legally do that work for pay.
2. Proof of a State License
New Jersey licenses individual locksmiths through the state board that also licenses electrical contractors, under a Fire Alarm, Burglar Alarm and Locksmith Advisory Committee.
To get that license, an applicant needs a high school diploma and a passing score on the state’s locksmithing exam.
A clean background check also matters: The applicant can’t have any serious (1st- to 3rd-degree) criminal convictions in the past decade.
On top of that, an applicant needs about 5,040 hours of hands-on locksmithing experience, roughly three full years, or a two-year federally approved apprenticeship instead.
That’s not a weekend course.
A separate business license covers the company itself, so a truck with a locksmith’s name painted on the side still needs paperwork behind it, too.
How to Check a New Jersey Locksmith’s License
New Jersey runs a free, real-time license lookup where anyone can search a locksmith’s name before letting them through the door.
A valid entry shows the license as current and lists any discipline on file, and a name that turns up nothing is a reason to call someone else.
3. Phone-Quote Trap
The same scam trips up New Jersey homeowners again and again, and licensed locksmiths see it every week.
A rock-bottom price quoted over the phone changes the moment someone shows up at the door.
The price never holds.
The Federal Trade Commission has warned about this pattern for years.
A caller gets a cheap quote, then the technician claims the job is more complicated once they’re already inside the house.
Cash, right then, is usually the ask.
A legitimate locksmith gives a price range before ever touching a lock, and puts the final number in writing once the job is done.
4. New Jersey’s Lock-Change Law
A domestic violence survivor who needs the locks changed today, not next week, sometimes calls a locksmith.
State law backs that request.
Under New Jersey law, a tenant who holds a restraining order can require the landlord to change the locks on the rental unit.
If the landlord hasn’t done it within 48 hours, the tenant is allowed to change the locks and seek reimbursement for the cost.
No general New Jersey law forces a landlord to rekey between ordinary tenants, which surprises many renters who assume a fresh key always comes with a fresh lease.
5. Rekeying Over Replacing
New Jersey’s locksmiths would rather rekey a good lock than sell a homeowner a brand-new one, and the price tag shows why.
Rekeying swaps the pins inside an existing lock so a new key works and the old one doesn’t, all without replacing the hardware.
The lock never changes.
That’s especially useful for anyone moving into a resale home.
Nobody can ever know exactly how many old keys are still out there.

6. Bump-Key Blind Spot
Many homeowners have no idea what locksmiths know well.
Many ordinary pin-tumbler locks, the kind on many front doors, aren't as tough as they look.
A specially cut bump key can pop many of these locks open in seconds, with a sharp rap instead of a delicate pick.
No damage shows.
Security researchers demonstrated the technique publicly in 2005, and it pushed lock makers to start building bump-resistant pins and sidebars into higher-end cylinders.
7. Your Lock's Grade Stamp
Tires carry a grade stamp everyone recognizes, and locksmiths judge a deadbolt's toughness the exact same way.
Many homeowners never check the number.
Look for a tiny stamp reading Grade 1, 2, or 3.
Grade 1 is built for commercial doors, Grade 2 is what locksmiths recommend for any exterior door, and Grade 3 is the bare minimum many builders install to save money.
That minimum grade turns up on new construction more often than many buyers expect.
Nobody upgrades it later.
8. That "Do Not Duplicate" Stamp
A "Do Not Duplicate" stamp raises the same question for locksmiths everywhere they work.
Does stamping "Do Not Duplicate" on a key stop someone from copying it?
Mostly, no.
The stamp carries no legal weight on an ordinary key, and a hardware counter can still cut a copy if it chooses to.
Only a patented, restricted keyway system, the kind that requires an authorization card from a locksmith, blocks unauthorized copies.
That stamp alone won't.
9. Smart Lock's Weak Link
The same design compromise shows up again and again when locksmiths install a smart lock.
Nearly every electronic deadbolt keeps a small backup keyway tucked into the faceplate for when the battery dies.
That backup cylinder is often a basic, low-security lock, no tougher than a bargain hardware-store knob.
It isn't the app.
It's the same little pin-tumbler cylinder locksmiths have been picking for years, sitting right behind the keypad.
A homeowner upgrading a smart lock should ask the installer about that backup cylinder, not just the app rating or the battery life.
Swapping in a higher-grade backup cylinder costs far less than replacing the whole smart lock, and many New Jersey locksmiths can do it in one visit.

ShopRite backs its low-price reputation with programs many regulars never fully use, and a few small habits at the register still add to every trip.
