Rekeying locks is the most common call we handle in Newark, and for good reason. Most homes here are 1960s-to-1990s tract construction with builders-grade Kwikset or Schlage knob-and-deadbolt combos, which means a move-in or a lost spare key usually calls for a full rekey rather than new hardware. Citadel Locksmith has served Newark since 2011, working residential, auto, and emergency calls across ZIP 94560. Call (833) 589-8078 for a free estimate.
Why Newark Homes Are Different
Newark is a single-ZIP bedroom community built almost entirely after 1960, which shapes nearly every locksmith job here. You won’t find a Victorian with a mortise lock that needs custom fitting. You’ll find single-story stucco ranches and two-story 1970s-90s subdivisions where every front door has a standard 2-1/8 inch bore and a deadbolt pre-drilled above the knob. That makes rekeys and hardware swaps straightforward, and it means we stock the cylinders and pins for those exact locks in the van.
The bay-adjacent climate does its own kind of damage. Dry summers and damp winters put salt air against exterior locks, gate latches, and mailbox locks, so seized or corroded cylinders are a recurring call in Newark neighborhoods from the 880 corridor to the Dumbarton approach. A lock that works fine in June might be sticky by February. This isn’t a frost problem like the Midwest, it’s a moisture and salt problem, and it changes how we clean and re-lubricate hardware before rekeying it.
Styles & brands we work with
Our Main Newark Services
Two services dominate our Newark calls: one for drivers, one for anyone who needs a door secure right now.
Car Key Replacement in Newark
Newark sits against the baylands and the Dumbarton Bridge approach, where sprawling apartment and shopping-center lots off the 880 corridor concentrate car problems. Lost transponder keys, broken fobs, and lockouts in a parking lot are standard work here. Our mobile service comes to your Newark driveway or the lot itself, cutting and programming on site so you never pay dealership fees. Full details are on our Car Key Replacement in Newark page.
Emergency Locksmith in Newark
Lockouts in Newark happen at the door of a tract house at midnight and in a car at a shopping complex by the freeway. We treat both as emergencies. Citadel’s emergency model is built into the service, not bolted on, so someone answers when you call outside standard hours. We’ll get your situation triaged, quote a full price, then dispatch.

Rekey Locks in Newark
Rekeying is the fastest way to take back control of who holds a key, and in Newark it’s nearly always a same-day job. The city’s post-war tract housing and 1970s-90s subdivisions were built with standard Kwikset and Schlage cylinders, so we arrive with the pins and key blanks already stocked and can rekey every lock in a three-bedroom Newark ranch in under two hours. The damp winter air that seizes cylinders also makes this a good moment to clean and lubricate, which we include on any Rekey Locks call.
Lock Rekey
Signs you need it
You’ve moved into a Newark home, ended a lease or a relationship, lost track of a spare key, or can’t account for every key a contractor or cleaner ever held.
What it costs in Newark
A standard single-cylinder rekey in Newark runs $55 – $90, and most homes need three to five cylinders done at once.
How we do it
We disassemble each cylinder, replace the internal pins so old keys stop working, cut new keys to match, and test every lock before we leave.
Rekey Door Lock
Signs you need it
You added a new deadbolt or handle to a Newark door and want every lock in the house on one key, or a specific door has a key floating around that other doors don’t.
What it costs in Newark
Rekeying a single door lock in Newark runs $55 – $110 depending on whether it’s a knob, a deadbolt, or both on the same door.
How we do it
We pull the cylinder, inspect the plugs and springs for the moisture wear common near the baylands, re-pin to the key you want, and reinstall with fresh lubricant.
Keyed Alike
Signs you need it
Your Newark front door, back door, garage side door, and deadbolts each need a different key, and you want one key to work them all.
What it costs in Newark
Keying alike costs $55 – $150 in Newark depending on how many cylinders we re-key to a single key, plus the new keys themselves.
How we do it
We re-pin every cylinder you want matched to the same key code, cut the new keys, then confirm the entire set opens every door smoothly.
Rekey Service
Signs you need it
You’ve just bought a Newark home built in the 70s or 80s and have no idea how many copies of the original key exist out there.
What it costs in Newark
A whole-house rekey service in Newark typically runs $75 – $160 for four to six cylinders plus the service call.
How we do it
We treat the whole property, not one lock: every entry cylinder, deadbolt, and usually the garage side door, all re-pinned and tested together.
What Rekey Locks Costs in Newark
| Item | Typical range in Newark |
|---|---|
| Single-cylinder rekey | $55 – $90 |
| Whole-house rekey (4 – 6 cylinders) | $75 – $160 |
| Keyed alike (multiple locks, one key) | $55 – $150 |
These are honest ranges based on Newark’s standard builders-grade hardware. The price we quote on the phone is the price on the invoice, no arrival surcharge added.
How long does a rekey take in Newark?
Most Newark homes take 45 minutes to two hours depending on cylinder count. A standard three-bedroom ranch with four entries is usually done in about an hour.
Is rekeying better than replacing locks in Newark?
For most Newark homes, yes. Builders-grade Schlage and Kwikset cylinders are solid enough to re-key for a fraction of the cost of new hardware, unless the lock is corroded from bay air beyond service.
Brands We Service in Newark
We work with the brands serious about security. In Newark that means a lot of Schlage and Kwikset on standard tract-home doors, plus Medeco and Yale when a homeowner wants a real upgrade. We stock common pins, cylinders, and blanks on the van, so most Newark rekeys and hardware swaps are finished in a single visit. See our brands for the full lineup.

What Newark Customers Say
"Programmed a transponder key for a 2014 model that the dealership wanted an absurd amount for. Same key, fraction of the price, took him twenty minutes in my driveway."
— Grace Lin"Locked out at eleven at night with a kid asleep in the car. He was there in 25 minutes, had the door open in under two, and did not do the thing where the price goes up once he's standing in front of you."
— Greg Lawson"Told me over the phone that what I needed was a five dollar part from the hardware store, not a locksmith. I called him back a month later for real work because of that."
— Yolanda Mendoza
