Rekey Service in Cerritos, Quoted Before We Start
Short answer: Most rekey service calls finish in one visit. A house with a front deadbolt, a couple of knobs and a garage entry door is a short job once the right pins are on hand. Julian's Locksmith books Cerritos appointments every day, 6:30 a.m. to 11:30 p.m. We're closed overnight. Call (951) 903-3193.

If you're searching for a rekey service, you've probably already settled the big question. You know the old keys have to stop working. What's left is deciding who does the job, what it will cost and when it can happen. This page answers those questions plainly. Julian's Locksmith is a licensed mobile locksmith (California license LCO7891) that rekeys locks at your door in Cerritos. We count your cylinders, quote the total, re-pin each lock to a new key, cut and test the new keys, and leave you with a clear record of what was done. No lock leaves the property, and no work starts until you've agreed to the price. Call (951) 903-3193 to book.
What to know first in Cerritos
A complete rekey service should leave you with more than a different key. When our visit ends you should have: every agreed cylinder re-pinned and back in its door; each lock tested from inside and outside with the door closed, not just turned on a bench; new keys cut from fresh blanks and tried in every lock they're meant to open; your old keys tried too, so you see them fail; and an invoice showing the business name, our license number LCO7891 and what was done. On request we'll note which doors share a key and which, if any, were left on a separate key, so you or a future property manager can follow it later. If we spotted a problem, such as a deadbolt that doesn't fully throw or a latch dragging on the strike, you'll hear about it with a price for fixing it. That's the standard to hold any rekey service in Cerritos to, including us.
How we can help in Cerritos
- Key cutting, spares and key counts. Every rekey service visit ends with keys cut from fresh blanks on our machine and tested in each lock. Tell us how many people need one and we'll cut that many, plus a spare for a lockbox or a trusted neighbor. Keys cut to the original code run smoother than copies made from worn copies.
- Business and master keyed rekeys. Commercial rekeys follow the same principle with more parts: mortise and rim cylinders, Adams Rite storefront locks, interchangeable cores and sometimes a master key system. Have the keying chart ready if one exists. If not, we can set up a simple system so managers carry a master while staff keys open only their own areas.
- Smart locks, keypads and backup cylinders. Rekeying the cylinder fixes only half of an electronic lock. The other half is codes, app users and shared digital keys. During the visit we re-pin the backup cylinder and help you delete old codes and users, so the person who had both a key and a code loses both at the same time.
- Padlocks, cam locks, RV and toolbox locks. Small locks get forgotten until they become the weak spot: a side-gate padlock still on the old key, a storage cabinet in the garage, a mailbox on a duplex wall. Some padlocks have removable cylinders that can match your house key, while cheap laminated ones usually get replaced. We'll tell you which is which.
- Lock health check during the visit. With a cylinder out of the door, we can see what the lock has been through. Worn pins, a cracked tailpiece or a latch dragging on the strike all show up. We clean and lubricate each cylinder, adjust strikes that bind, and flag anything that needs replacing, priced separately so the choice stays yours.
How Cerritos shapes the job
In family neighborhoods, keys wander: a teenager's backpack, a babysitter who moved on, a neighbor who watered plants two summers ago. A rekey service brings it back to the people living there. Most homes need the front, garage entry and back or side door, plus the side-gate padlock. Cut a key for each driver in the house and one spare, and keep the list.
Storefronts usually run Adams Rite deadlocks with mortise cylinders, a rear steel door with a rim or mortise lock, and an office or stock room inside. When a key-holding employee leaves, a rekey service after closing gets all of it done before the next morning's shift. Shopping centers in Cerritos sometimes control the rear corridor doors themselves, so check your lease before we touch those.
Condos and townhomes split ownership in ways that matter for a rekey. Your unit door, patio gate and garage entry are usually yours; the building entry, trash room and pool gate usually belong to the HOA. The mailbox may be owned by the association or by the Postal Service. We rekey what's yours on the spot in Cerritos and tell you who to ask about the rest.
Situations this covers
- A typical call: a landlord with a duplex near Don Knabe Community Regional Park has a tenant moving out on Sunday afternoon. We meet the owner after the final walk-through, rekey the unit's front deadbolt, knob and back door to a new key, cut three keys for the next tenant and one for the owner, and test every one before the owner locks up for the night.
- Imagine an RV owner parked at home off I-5 who finds that a neighbor's compartment key opens his storage bays. That's the CH751 problem: one common factory key across many models. We swap each compartment cam lock for a uniquely keyed one, all matched, cut him three keys, and check that the entry door lock is on a different key from the bays.
- Say you rent a house and the landlord agrees in writing that you can rekey because a former roommate never returned a key. You call with the landlord's email ready. We verify your ID and lease, rekey the two exterior doors, and cut an extra key that you hand to the landlord, so the owner keeps the access the lease requires.
- For example, an adult daughter arranges a rekey service at her father's house after a home-care agency changes caregivers. She can't be there, so her father, the owner, shows his ID at the door, and she joins by phone to approve the quote. We rekey the front and side doors, cut keys for the family and the new agency, and leave the old ones useless.
Step by step with Julian's Locksmith
- Call with your lock count. Before you dial, walk the property once and count keyholes, not doors. A deadbolt and a keyed knob on the same door count as two. Note anything unusual, such as a smart lock, a lock with no working key, or a commercial door closer, and mention it when you call.
- Get the quote and a time. Pick a time when someone authorized can meet us. For a rental, that's usually the owner or manager; for a business, someone who can sign off. We confirm the appointment, the address and the scope, so there are no surprises when the van pulls up in Cerritos.
- Show authorization at the door. Verification protects you as much as anyone. If someone without authority could book a rekey service and lock you out of your own home, that would be a serious problem. Have your ID and one document tying you to the property ready, and this step takes very little time.
- Confirm the scope together. A two-minute walk-through prevents most misunderstandings. We check brands and keyways against the plan, note any lock that needs a different cylinder to match, and agree on the number of keys. If something on the list doesn't make sense to rekey, we explain why before starting.
- Re-pin, cut and test. Each cylinder comes out, the plug is emptied with a follower and re-pinned to the new combination, and the lock goes back in. We cut keys to that code and test each one in every lock, from both sides, with the door closed, because a lock that turns on the bench can still bind in the frame.
- Wrap-up and paperwork. Before we leave, you get the new keys, a quick demonstration that the old ones no longer turn anything, and an invoice listing the work, our business name and license number LCO7891. If we noticed a lock that needs attention later, we'll mention it, with no pressure to fix it today.
Pricing factors
- Lock brand and cylinder type. Standard Kwikset, Schlage and Yale residential cylinders are routine. Mortise cylinders, interchangeable cores, master keyed commercial locks and high-security brands such as Medeco or Mul-T-Lock take more time or factory parts. Budget hardware sometimes can't be rekeyed at all. Brand and type explain why two locks can carry different prices.
- Keys: how many and what kind. Each rekey includes keys, and extras add to the total. Standard brass blanks for common keyways are inexpensive; restricted keyway blanks, which hardware stores can't copy, cost more and may need ordering. Decide who really needs a key before the visit, so you pay for the right number.
- Surprises found on site. Sometimes a lock fights back: a seized cylinder, a broken key fragment in the keyway, a stripped set screw or a cylinder with no working key that has to be decoded or picked first. Those take extra time. When we find one, we stop, explain and requote before continuing, so you're never surprised by the invoice.
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 Cerritos.
What to do before we arrive
- Collect every key you have, even mystery keys from the junk drawer, and set them out for the locksmith. Testing them shows which locks share a key and sometimes reveals a lock you forgot about. After the rekey, those old keys are useless, so you can recycle them.
- Use the visit to ask questions. How old are these locks? Is the strike anchored into the framing? Would a restricted keyway make sense here? A locksmith standing at your door in Cerritos can give you advice specific to your hardware that no article can.
- Think about the locks that aren't on doors: side-gate padlocks, a privately owned mailbox, a garage cabinet, a truck toolbox or RV compartment. Adding them to the visit is far cheaper than a separate trip later, and it closes gaps people tend to forget until a key goes missing.
- Book ahead if your move or opening falls on the weekend. Weekends run our regular hours, but the busiest slots fill early. Call a few days out when you can, though we do fit same-day calls in Cerritos when the route allows.
Mistakes to avoid
- Hiring whoever quotes lowest over the phone without any questions about your locks. A real quote depends on cylinder count, brands and key count. A teaser figure that ignores all three tends to grow at the door, sometimes after a lock has already been taken apart.
- Waiting for a convenient weekend that never comes. Old keys keep working every day you postpone. If evenings suit you better, book an evening slot; our hours run late every day, weekends included, so the rekey doesn't have to wait for a day off.
- Assuming a rekey fixes a lock that doesn't latch. If the deadbolt doesn't fully throw into the strike, or the latch misses its hole, a new key won't help. Mention door problems when you book so the visit covers alignment, not just pins.

Frequently asked questions
Do you rekey on site, or do I bring my locks to a shop?
On site. Julian's Locksmith is a mobile locksmith, so the rekey happens at your door. Each cylinder comes out, gets re-pinned in our van or on the porch, and goes back in before we move to the next lock. Your doors are never left without a working lock, and you don't have to remove hardware yourself or drive anywhere in Cerritos.
Do you rekey RV, toolbox or trailer locks?
Yes, in many cases. RV compartments and truck toolboxes commonly use cam locks on the shared CH751 key, so we usually replace those cam locks with uniquely keyed ones that all match each other. Some RV entry door locks can be rekeyed or replaced as well. Ignition and vehicle door locks are a separate automotive job; ask when you call.
Can a renter book a rekey service?
With the landlord's written consent, yes. Most leases forbid changing locks without permission, and the owner usually needs a key. Bring the lease and the written approval, and we'll cut an extra key for the landlord. Under Civil Code 1941.5 and 1941.6, California landlords must change locks within 24 hours of a tenant's written request in certain protective-order situations.
How many keys come with a rekey?
You tell us how many you need. We cut each key on our machine from a fresh blank to the new combination and test it in every lock it should open. We'll suggest keeping the count to what people actually use, plus one spare. Additional keys can be cut during the visit or later, and restricted blanks can be ordered.
What happens if one of my locks can't be rekeyed?
We tell you before doing anything to it. Locks that sometimes can't be rekeyed sensibly include seized or badly worn cylinders, cheap locks whose parts aren't sold separately, warded skeleton-key locks, and some smart locks with proprietary backup cylinders. For each, we'll quote a replacement keyed to match the rest, and you decide whether to go ahead.
Do I need to be home during the rekey?
Someone authorized needs to be there. That can be you, or a person you've authorized in writing who shows their own ID, such as a property manager or a relative. For rentals and businesses, the owner or manager can send authorization ahead of time. We won't rekey an empty property for someone who can't show they have the right to change the locks.
How far is Cerritos from your base?
Cerritos is about 65 miles from our San Bernardino base, roughly 66 minutes in light traffic. Arrival time depends on traffic and on the job the technician is finishing, so we give you an estimate on the phone before you commit.
