Rekeying is the locksmith service Fullerton calls for most, and for good reason. The city’s mix of 1920s downtown homes with original mortise locks, mid-century tract houses, and high-turnover rentals near Cal State Fullerton means old keys keep circulating long after ownership changes. If you’ve just closed on a 1930s Spanish Revival near the downtown core or need a rental unit rekeyed between tenants in 92831, call us at (866) 497-9415. We’ll send a technician who knows which vintage hardware still works and which hardware has quietly become a liability.
Why Fullerton Homes Are Different
Fullerton’s housing stock spans nearly a century of lock technology, and that changes the job. Downtown, the pre-war craftsman bungalows and Spanish Revival homes often still carry their original single-cylinder mortise locks and glass-knob doors. Those locks were built well, but the cylinders inside are usually original too, and a skeleton key from 1925 doesn’t give you security anymore. We routinely source replacement mortise cylinders or convert those doors to modern deadbolts that fit the existing door prep without butchering the wood.
The climate does its own damage. Santa Ana winds and long dry summers shrink wood door frames, so strikes and deadbolts drift out of alignment. A lock that worked fine in March may bind by September. In the mild, damp weeks of early spring, older doors swell back the other way. We adjust strike plates, lubricate cylinders, and realign deadbolts seasonally for homeowners who’ve learned to expect the shift.
Then there’s the rental market. The apartments and duplexes around Cal State Fullerton turn over on a semester rhythm, and property managers in the 92831 and 92832 ZIP codes need rekeys done fast between tenants. A Kwikset smart-key is quick, but a Schlage or Baldwin cylinder may need pinning. Either way, the job has to be right the first time, because the next tenant is already scheduled to move in.

Rekey Locks in Fullerton
Rekeying in Fullerton is usually the smartest money you can spend on a door, and we’ll tell you straight when it isn’t. In a city with this much vintage hardware and this much turnover, a rekey often turns into a parts-hunting job, because the original mortise cylinders in those downtown bungalows aren’t made anymore. We stock common replacements and can source the odd ones, and we’ll tell you if your door is a better candidate for a modern deadbolt conversion. Rekeying is often the smarter move – we’ll tell you which is right for your situation. When we say we rekey, we mean pins and springs inside the cylinder replaced, new key cut to spec, and the old key rendered useless – that’s the core of the work described on our Rekey Locks service page.
Lock Rekey
Signs you need it
You’ve moved into a Fullerton home, you’ve lost track of who has a copy of your key, or a roommate, tenant, contractor, or cleaner is no longer authorized.
What it costs in Fullerton
Standard cylinder rekeying in Fullerton typically runs $20 to $35 per cylinder, with most homes landing between $70 and $140 for a full entry set.
How we do it
We disassemble the cylinder, replace the pins to match a new key, reassemble, and test the lock through several open-close cycles before we consider the job done.
Rekey Door Lock
Signs you need it
A single door has a key that’s been lent out too many times, or the deadbolt and knob are keyed differently and you want one key to work both.
What it costs in Fullerton
For one door with a deadbolt and knob, expect $45 to $80, including cutting two new keys.
How we do it
We match the new key to both cylinders on the door, confirm the strike aligns properly, and hand you keys that turn smoothly without jiggling.
Keyed Alike
Signs you need it
You’re carrying a different key for the front door, the back door, the garage, and the side gate, and you want all of them to share one key.
What it costs in Fullerton
Keyed-alike service runs $25 to $40 per additional cylinder after the first, so a four-lock house usually lands between $110 and $180.
How we do it
We pin each additional cylinder to the same key pattern, so one key operates every door, while the original keys stop working entirely.
What Rekey Locks Costs in Fullerton
| Item | Typical range in Fullerton |
|---|---|
| Standard cylinder rekey | $20 – $35 per cylinder |
| Deadbolt + knob on one door | $45 – $80 |
| Keyed alike (per additional cylinder) | $25 – $40 |
Labor is the main variable because Fullerton doors vary so much. A 1920s mortise cylinder takes longer to rekey than a 2005 Kwikset knob, and we quote that difference upfront. Call (866) 497-9415 for an exact quote – estimates are free.
How much does it cost to rekey a house in Fullerton?
Most Fullerton homes cost $70 to $180 to rekey, depending on how many cylinders and whether any vintage mortise locks need special parts. Call (866) 497-9415 for a firm quote before we dispatch.
Is rekeying better than replacing locks in Fullerton?
Usually yes. If your existing hardware is Schlage, Kwikset, or Baldwin and mechanically sound, rekeying costs a fraction of replacement. We’ll tell you if a lock is worn out and should be replaced instead.
Brands We Service in Fullerton
We work on the lock in front of us – not just the brands we prefer. That means Kwikset and Schlage hardware in rental units, Medeco on commercial doors, and Baldwin or Yale on higher-end Fullerton homes. High-security hardware like Medeco requires a locksmith who knows it cold – that’s us. We keep common parts stocked locally for most brands. See our brands for the full list of eight we’re certified to service.
Pricing for Locksmith in Fullerton, CA
| Service | Typical range in Fullerton |
|---|---|
| Lock rekey (per cylinder) | $20 – $35 |
| Rekey door lock (deadbolt + knob) | $45 – $80 |
| Keyed alike (per additional cylinder) | $25 – $40 |
| House lockout (daytime) | $65 – $100 |
| Deadbolt installation | $75 – $145 |

| Car key replacement (transponder/fob) | $150 – $300 |
| Commercial door rekey (per cylinder) | $30 – $50 |
Vintage mortise cylinders on pre-war Fullerton homes push rekey prices toward the top of the range because the parts are slower to source and the work is more detailed. High-security keys for Medeco or Mul-T-Lock run higher because the blanks are controlled. Whatever the job, the price we quote on the phone is the price on your invoice – no call-out surcharge added on arrival, no bait-and-switch.

— Beatriz Torres"Does good work. Card payment was a bit of a production, so have another option handy."
— Stephanie Schaefer"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."
