Rekeying locks is the most common job we handle in Duarte, and the reasons are specific to this city. The housing stock here skews toward mid-century ranch homes and stucco tracts built between the 1950s and 1970s, and many of those original locks have been turning for 50 or 60 years now. Add the dry, dusty air that works grit into door hardware, and you get locks that stick, keys that wear down, and homeowners who want a fresh start without replacing every piece of hardware. Call True Blue Locksmith at (877) 358-5506 for an honest quote on rekeying your Duarte home.
Why Duarte Homes Are Different
Duarte sits right at the edge of the San Gabriel Mountains, and the housing reflects that geography in ways that directly affect lock work. The neighborhoods tucked up near the foothills, especially in the 91008 and 91010 ZIP codes, include larger estate properties with long driveways, automatic gates, and exterior storage. Those properties often have gate operators and high-security hardware that need a locksmith comfortable with commercial-grade equipment, not just standard residential locksets. Down on the valley floor, the older ranch tracts along the 210 corridor run much simpler hardware: original mortise locks, builder-grade knob locks, and Kwikset or Schlage deadbolts that have outlived their useful service life.
The climate does its part too. Hot, dry summers and Santa Ana wind events pull moisture out of wood doors and jambs until they swell or shrink, and locks that were once perfectly aligned start to bind. Seasonal dust and grit from the washes and foothill canyons work into exterior locks and gate mechanisms, which is why we see so many Duarte homeowners in the fall struggling with backyard gates that will not open ahead of fire-season clearance inspections. A lock that worked fine in May can be nearly impossible to turn by October.
Styles & brands we work with
Our Main Duarte Services
Rekeying is the service Duarte homeowners call us about most, but two other jobs come up constantly in this area: car key replacement and emergency lockout response. Here is what each one involves in Duarte specifically.
Car Key Replacement in Duarte
Duarte drivers park in a mix of open driveways, carports on older ranch properties, and hillside lots where a dropped key disappears into landscaping or down a slope. When a car key is lost or a transponder key stops working, the fix depends on the vehicle’s year and make, and many newer models need on-site programming that only a locksmith with automotive key equipment can handle. We carry key blanks and programming gear for a broad range of domestic and import vehicles, so one call covers most Duarte car key jobs. The full process and pricing are covered on our dedicated page: Car Key Replacement in Duarte.
Emergency Locksmith in Duarte
Lockouts in Duarte happen at all hours, and the older housing stock has a way of making them worse: a worn mortise lock on a 1960s front door can jam in a way that a newer deadbolt never would. Whether you are locked out of a house on a cul-de-sac near Royal Oaks Park or cannot get into your car along Huntington Drive, the priority is getting you back in without damaging the door or frame. We handle residential, commercial, and automotive lockouts across Duarte. Details on response and what to expect are on this page: Emergency Locksmith in Duarte.

Rekey Locks in Duarte
Rekeying a lock in Duarte means changing the internal pins and springs so that the old key no longer works and a new key operates the same lock. It is the fastest, most affordable way to take control of who can open your doors, and in a city with this much aging hardware, it is usually smarter than replacing the entire lockset. True Blue Locksmith has served Duarte since 2017, and we rekey Schlage, Kwikset, Yale, Baldwin, and Medeco hardware on a regular basis. For more on how rekeying works across different lock types, see our full Rekey Locks service page.
Lock Rekey
Signs you need it
A key that turns but with increasing resistance, or a key that no longer fits smoothly after years of use, is often a sign the lock cylinder needs rekeying rather than replacement.
What it costs in Duarte
Rekeying a standard cylinder lock in Duarte typically runs $20 to $50 per lock, depending on the lock type and key style.
How we do it
We remove the lock cylinder, swap the old pins for new ones matched to a fresh key, and reinstall the cylinder so the old key is permanently invalid.
Rekey Door Lock
Signs you need it
After moving into a new home, losing a spare key, or ending a tenancy, the smart move is to rekey every exterior door lock so no unknown key still operates your entry points.
What it costs in Duarte
Rekeying a door lock in Duarte runs about $20 to $50 per cylinder, with additional labor if we are rekeying multiple doors in one visit.
How we do it
We rekey each door lock to a single new key, test the deadbolt and knob for proper alignment in the door frame, and hand you all copies of the new key.
Keyed Alike
Signs you need it
When you carry two or three different keys for your front door, back door, side gate, and garage, having everything keyed alike means one key operates every lock.
What it costs in Duarte
Keying multiple locks alike in Duarte costs the per-cylinder rekey fee of $20 to $50 per lock, and we can match all locks to one key during a single visit.
How we do it
We rekey each lock’s cylinder using the same key code so one key turns every lock, then test each one before we leave.
What Rekey Locks Costs in Duarte
| Item | Typical range in Duarte |
|---|---|
| Rekey a standard cylinder lock | $20 – $50 per lock |
| Rekey a mortise lock | $30 – $75 per lock |
| Keyed alike (multiple locks) | $20 – $50 per lock |
How long does a rekey take in Duarte?
Most Duarte rekey jobs are done in 30 to 60 minutes for a standard front and back door, depending on how many locks are involved. Higher-security hardware takes longer.
Should I rekey or replace my locks in Duarte?
Rekey when the lock mechanism itself works fine and you want a new key. Replace when the lock is rusted, visibly damaged, or you want upgraded smart or high-security hardware. Call (877) 358-5506 for a straight answer on your specific locks.

What Duarte Customers Say
"Commercial job, panic bar and a master key system for a small office. Clean install and clear documentation of which key opens what."
— Norma Castillo"Rekeyed every lock in the house the day after we closed. Six doors, all matched to one key, done in about ninety minutes."
— Arjun Mehta"The old deadbolt was mounted crooked by whoever lived here before and had been sticking for years. He redrilled and reset it properly rather than just replacing the hardware."
— Miguel Salazar
