Rekeying locks is the service Duarte homeowners call us about most often, and it’s easy to understand why. Much of the housing stock in the 91010 valley floor dates to the 1950s through 1970s, and those original knob-lock and deadbolt setups have changed hands many times over the decades. Between the aging hardware and the grit that Santa Ana winds push into door mechanisms, a straightforward rekey often turns into a rekey plus strike-plate and cylinder work. If you’re locked out or locking down, call (866) 497-9415 and we’ll walk you through what’s needed.
Why Duarte Homes Are Different
Duarte sits at the base of the San Gabriel Mountains, and that position shapes nearly every lock we service. Homes on the flat valley floor in 91010 are mostly mid-century ranch and tract builds with original or lightly updated hardware. The knobs and deadbolts on those doors have typically seen fifty or sixty years of use, which means worn pins, loose strikes, and keyways clogged with decades of dust. Up the hill in 91008, the picture changes: larger estate properties, gated entries, and commercial-grade locks that demand a heavier toolkit.
The climate does real work on exterior locks here. Hot, dry summers bake the rubber weather seals around entry doors until they crack and let fine grit inside the cylinder. When the Santa Anas blow through, that dust works its way into keyways and latch mechanisms, which is why a key that worked fine in June might stick hard in October. We see this cycle every year in Duarte, and we approach every exterior lock with the assumption that it will need cleaning, not just new pins.
Then there’s the City of Hope campus, which anchors a steady stream of commercial and institutional rekeying in Duarte. Medical and research buildings need master-key systems and restricted keyways, and that demand pattern is something you won’t find in most foothill towns this size. Greystone Locksmith has served Duarte since 2011, and that tenure means we know both the 50-year-old hardware on the valley floor and the high-security systems on the hillside.
Styles & brands we work with
Our Main Duarte Services
Two services account for most of the calls we take from Duarte residents: car key replacement, which we handle in the field and not through a third party, and emergency lockout response for the moments that can’t wait.
Car Key Replacement in Duarte
Losing a car key in Duarte usually happens at the worst possible time, and the thin keyway tolerances on modern transponder keys mean a hardware-store copy won’t start the ignition. We handle automotive key cutting and programming in the field, covering the full range from basic non-chip keys to transponder and remote-head keys. The hot valley sun is also rough on key fob batteries, so if a fob stops responding in a Duarte parking lot, we can test and replace it on the spot. For the full breakdown of what we cover, see Car Key Replacement in Duarte.
Emergency Locksmith in Duarte
An emergency lockout at midnight in Duarte isn’t the time to be researching credentials. Our emergency response covers residential lockouts, broken-key extractions, and failed deadbolts, and we arrive with the tooling to solve the problem in one trip rather than telling you the door needs to be drilled and then leaving you with a frame repair bill. During Santa Ana wind events, we also see an uptick in doors that won’t open because the latch has bound against a warped strike plate. Emergency Locksmith in Duarte covers response, what to expect, and how to prepare before you call.

Rekey Locks in Duarte
Rekeying is the fastest way to take control of who can open your doors, and in Duarte the case for it is obvious: most valley-floor homes in 91010 have had multiple owners, tenants, contractors, and caregivers with key access over the years. Add in the dust and grit that works into old cylinders, and a rekey often becomes a cleaning and pin-replacement job that makes the lock operate like new. If you’ve moved into a mid-century ranch or a hillside property in 91008 and can’t account for every key that’s ever been cut, a rekey through Rekey Locks is the affordable fix we recommend before full replacement.
Lock Rekey
Signs you need it
You’ve moved into a new home, had renovation work done by contractors, or simply lost track of who has a copy of your key.
What it costs in Duarte
A standard pin-and-tumbler rekey in Duarte typically runs $65 to $130 including a service call, depending on the number of cylinders and keys needed.
How we do it
We remove the cylinder, replace the pins to match a new key, lubricate and clean the internal components, then test the key in the lock before we leave.
Keyed Alike
Signs you need it
You’re carrying a keyring with three or four different keys for the front door, back door, garage, and side gate, and you’d rather have one key that turns them all.
What it costs in Duarte
Keying multiple locks alike in Duarte runs roughly $20 to $40 per cylinder after the service call fee, with the total depending on how many locks we’re matching.
How we do it
We repin each cylinder to the same key cut, confirm that every lock has the same keyway type, and verify operation on all doors before handing over the new keys.
What Rekey Locks Costs in Duarte
| Item | Typical range in Duarte |
|---|---|
| Rekey first lock (includes service call) | $65 – $130 |
| Each additional cylinder | $20 – $40 |
| New key copies (per key) | $5 – $12 |
Is rekeying better than replacing my locks in Duarte?
Usually yes. Rekeying keeps your existing hardware while changing the internal pins so old keys stop working, which costs less than new hardware. We’ll tell you if a lock is too worn to rekey.
Will my rekeyed locks still work with the original Duarte house keys?
No. The old keys will stop working the moment we repin the cylinder. You’ll get new keys that match the new pin configuration, and we can cut as many copies as you need.
Brands We Service in Duarte
We work on the lock in front of us, not just the brands we prefer. In Duarte that means a lot of Schlage and Kwikset on valley-floor homes, plus Medeco and Yale on hillside estates and City of Hope buildings. We stock common pins, springs, and key blanks locally so most rekeys and repairs are same-day jobs. See our brands for the full breakdown.

What pushes prices up in Duarte is usually cylinder condition and access. A 1960s knob lock that has never been lubricated takes longer to clean and repin than a newer deadbolt, and hillside properties in 91008 with gated entries or alarm-integrated locks can add labor time. Whatever the job, the price we quote on the phone is the price on the invoice, and we never add a call-out surcharge on arrival.

What Duarte Customers Say
"Rekey was done properly. One of the keys he cut was slightly stiff in the back door and I had to call him to swap it, which he did without a fuss."
— Neil Mehta"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."
— Shannon Hoffman"Key snapped off in the deadbolt. He extracted it without damaging the cylinder, which I did not think was going to be possible."
— Beatriz Torres
