Duarte, Los Angeles County
Rekey Locks in Duarte and Carry One Key for Every Door
Short answer: The right time to rekey is the day the risk begins, not after something goes missing from the house. Lost keys tied to your address, a move-in with unknown copies floating around, or a rental turnover all qualify. In Duarte, we come to the property, verify that you own or manage it, and hand you new keys that run every rekeyed door.

Roommates move on, relationships end, and keys don't always come back. Even when they do, nobody knows how many copies were cut at a hardware kiosk along the way. The clean fix is to rekey locks once the other person's belongings are out. Julian's Locksmith handles these calls across Duarte quietly and quickly: we confirm you live there or own the property, change the pinning in your deadbolts and knobs, and give you a fresh set of keys you control. Renters, check your lease first, because many require landlord approval. We're glad to work with your manager so a copy of the new key reaches them properly.
The best time to rekey locks is the day you get the house, and the next best is any time you can't account for every key. In Duarte the triggers are familiar. You just bought a house near the high school and the former owner's key count is a mystery. A roommate or ex-partner moved out and kept a key. A landlord turned a unit over after a tenant left. A key vanished in a City of Hope parking lot, or a contractor finished a remodel and still knows the lockbox code. The visit itself is short. We rekey the front deadbolt, back door, garage-entry door and any side-gate lock, and pin them so one key opens everything. You get new keys, we test each lock from both sides, and the old keys stop working at once. For a rental, we can leave a master key for the owner and a separate key for each tenant. Price depends on the number of cylinders and on whether the locks are worth keeping. You will have the number before we begin.
What to know first in Duarte
Most people call to rekey locks because of who might have a key. Many hang up with a second benefit they hadn't considered: the chance to carry one key for the entire house. When we rekey locks in Duarte, every cylinder that shares a keyway can be set to the same new key, so the front deadbolt, front knob, back door, garage entry and even the side gate answer to one key on your ring. The catch is the keyway. Kwikset and Schlage, the two most common residential brands here, use different key profiles, and neither key slides into the other's locks. Homes where every lock came from the builder at the same time usually match. Homes that have been through decades of replacements often don't. In those cases we identify which locks are the odd ones out and offer two paths: replace those few to match the majority, or leave them on a second key. Either way, you see the plan and the quote before any lock comes off the door, and old keys stop working on every lock we rekey.
Work included on a typical visit
- Ex-roommate, partner and family changes. Divorce and separation calls need tact and paperwork. We confirm the person requesting the rekey has the right to do so, which may mean a deed, lease or court order, then re-pin the locks and hand over new keys. If both parties are still on title, settle that first; we don't take sides.
- Keying every door alike. Keyed-alike setups work best when you decide the plan before we start. Should the detached garage or workshop share the house key, or stay separate? Does the gate padlock need to match? We map it out with you, then pin every chosen cylinder to the same cuts and test each door.
- Rekeys after a break-in or stolen car. If a burglar took keys, a garage remote or papers with your address, the locks those keys open are compromised even though the doors still close. After the police report, we rekey every affected door and check strikes, frames and cylinders for damage that calls for repair or replacement instead.
- Protective order and safety rekeys. If someone you need protection from had a key, call us. California tenants with a qualifying protective order or police report can ask their landlord to change the locks within 24 hours. We work with landlords, managers and tenants to rekey quickly, and we keep the details of the visit private.
- Garage entry, gates, padlocks and outbuildings. Detached garages, casitas, pool equipment gates and RV gates are common on larger lots, and each one is another key on someone's ring. We can rekey outbuildings to match the house, or keep them on a second key if a gardener or pool tech needs access you don't want extended to the front door.
Local factors in Duarte
Busy households lose keys constantly: on sports fields, in backpacks, at friends' houses. In family neighborhoods across Duarte, a keyed-alike rekey simplifies daily life, since everyone carries one key that opens the front door, back door and garage entry. Pair it with a keypad deadbolt on the door the kids use most, and a lost key stops being a reason to rekey every season.
Clinics and medical offices hold patient records and controlled supplies, so key turnover matters more than usual. When a staff member leaves, rekey the suite entry, medication room and records storage, and track who carries each key. Restricted keyways stop casual copying. For suites in a managed building near Duarte/City of Hope station, we work within the building's master system with the property manager's approval.
Older homes in Duarte tend to collect locks one repair at a time: an original brass knob, a deadbolt added decades later, a garage entry lever from whatever was on sale. Before you rekey locks in a house like that, expect a mix of keyways and at least one cylinder too worn to save. We sort the keepers from the replacements so the final ring holds one key instead of four, and we flag any door where the frame needs attention.
Common situations
Imagine a landlord with a duplex south of Huntington Drive. One tenant moved out last week, and the other asked for new keys after a visitor lost a set. Four doors in total, plus a shared laundry room. We would rekey each unit's front and back doors to its own key, keep the laundry room on a separate key that both tenants can use, and give the landlord a master that opens everything for emergencies. Nobody has to move out or wait for new hardware.
- A typical post-remodel call: a kitchen and bath renovation wraps up after four months, during which the crew used a lockbox key and the homeowner handed two more copies to subcontractors. Once the final inspection signs off, we rekey every exterior door and the garage entry, and the homeowner pulls the lockbox off the hose bib that same afternoon.
- Picture siblings settling a late parent's estate near Duarte Community Center and Duarte Sports Park. Neighbors, a caregiver and two cousins all had keys at one point or another. The executor shows letters testamentary, and we rekey the house to one new key, cut exactly three copies for the siblings, and replace a seized back-door deadbolt that couldn't be saved after years of sitting unused.
- Say a commuter's backpack is stolen from a car at a park-and-ride. Inside were house keys, a garage remote and a wallet with a driver's license, so the address is now in the wrong hands. We get the call that afternoon, verify residency with a passport and a utility bill, and rekey all four exterior cylinders while the owner clears the opener's memory.
Step by step with Julian's Locksmith
- Tell us why you're rekeying. Describe what's on each door: front deadbolt and knob, back door, garage entry, side gate, security screen. Photos of lock faces and key heads help most. Mention any smart lock too, since its backup key cylinder can usually be rekeyed with the rest.
- Confirm who's authorizing the work. Before any lock comes off a door, we confirm you have the right to rekey it: ID plus a deed, closing statement, lease, utility bill or management agreement. It protects you as much as anyone, because the same rule keeps a stranger from rekeying your house.
- Agree on the keying plan. Next we settle the keying: one key for everything, or separate keys for the house and outbuildings. We check each cylinder's keyway first. If one lock won't match the rest, you choose between a second key and replacing that lock before we begin.
- Re-pin each cylinder. Each cylinder comes out of its lock, gets new key pins sized to the new key, and goes back in. Your hardware stays on the door, and the latch and bolt keep working the way they always did. Tired springs or worn pins are replaced as we go.
- Test every key in every door. Testing covers every key we cut, not one sample. Inside thumbturns, garage entry knobs and gate latches get checked as well. If a door sticks in summer heat or the bolt rubs the strike, we correct the alignment so the new key turns smoothly through every season.
- Hand over keys and a key list. The visit ends with keys in hand and a quick review: which doors share the key, which stay separate, and where the spare should live. We also remind you to reset garage remotes and smart lock codes, since a rekey changes keyed cylinders only.
Pricing factors
- Whether you have a working key. SmartKey locks without a working key can't be reset the normal way and are usually picked, decoded or replaced, which takes longer. Schlage and similar locks can be picked open and then re-pinned. A key in hand is always the least expensive starting point.
- Keying plan and number of keys. How many copies do you need? Two per adult is typical; landlords often want two or three per unit plus an office copy. Standard brass blanks are inexpensive to cut on the spot. Restricted keyways that block casual copying cost more but give you real control over duplicates.
- Timing and travel. Distance from our San Bernardino base plays a part, since we're fully mobile and drive to every job. Combining your rekey with other work on the same visit, like a deadbolt install or extra key copies, saves you from paying for a second trip later.
Every job gets a clear quote before any work starts. Call (951) 903-3193 with the details and we'll tell you what to expect for your situation in Duarte.
Practical tips before you call
- Ask for fewer keys than you think you need. Every extra copy is one more key to track. Two per adult resident and one spare stored with someone you trust covers most households, and more can be cut later from the same code if needed.
- Consider a restricted keyway if you hand out keys often. Standard house keys can be copied at any hardware kiosk, while restricted keys require authorization to duplicate. That gives landlords, home offices and multigenerational households real control over how many copies exist.
- Lost keys without ID? Think about where they disappeared. Keys dropped on a hiking trail carry less risk than keys taken from a gym locker along with a wallet. Rekeying costs little compared with years of wondering, but the second case shouldn't wait a single night.
- Rekey the day your situation changes. The best moment is the day you get possession, the day a roommate's last box leaves, or the day you realize keys are gone. Every day in between is another day an unknown copy still opens your door.
What not to do
- Cutting a pile of copies right after the rekey. Each extra key you make and hand out recreates the problem you just paid to solve. Start small, track every copy you issue, and add more only when someone genuinely needs one.
- Rekeying a lock that should be replaced. A loose, sagging or sticky deadbolt that's been rekeyed is still a weak deadbolt. If the bolt won't fully throw or the cylinder spins in the door, fix or replace it first, then key the new hardware to match.
- Buying a DIY rekey kit for a house with mixed brands. Kits fit one brand and one keyway, and SmartKey resets can jam if the key comes out at the wrong moment. A half-finished rekey often leaves a door that no key will open at all.

Frequently asked questions
Can you make all my house locks work with one key?
In most homes, yes. Locks that share a keyway, such as several Kwikset or several Schlage pieces, can be rekeyed to the same new key in one visit. If one lock is a different brand, we either replace that lock or its cylinder, or leave it on a separate key. We'll show you which doors match before quoting anything.
Does rekeying change my smart lock or keypad?
Only the key cylinder. Most smart deadbolts with a keyway, such as Schlage Encode, Kwikset Halo and Yale Assure models, have a backup cylinder that can be rekeyed with the rest of the house. Codes, fingerprints and app access are separate; delete old ones yourself or let us walk you through the reset while we're there in Duarte.
When should I rekey my locks in Duarte?
Rekey whenever you can't say for certain who holds a key: moving into a new home or rental, losing keys, a roommate or partner moving out, a tenant turnover, after contractors or caregivers had access, or after a break-in. If your hardware works well, a rekey resets access without replacing anything. Call (951) 903-3193 and tell us which situation you're in.
Can you rekey my locks today?
Often, depending on the schedule and your distance from our San Bernardino base. Urgent rekeys after stolen keys or safety concerns get priority when we can manage it. We work every day, 6:30 a.m. to 11:30 p.m. Call (951) 903-3193 for an honest ETA to Duarte.
What do I need to show before you rekey?
Photo ID plus something that ties you to the property: a deed, closing statement, lease, recent utility bill or property management agreement. Landlords and managers show ownership or authority, while executors bring letters testamentary or trust documents. We won't rekey a lock for anyone who can't show they have the right to, and that rule protects you too.
Can I rekey my apartment as a renter?
Usually only with your landlord's permission, and many leases require you to give them a copy of the new key. Some complexes run master key systems that a tenant rekey would break. Ask management first; if they approve outside work, we'll verify your lease and the approval, rekey the unit, and help get a key to the office.
How far is Duarte from your base?
