Why change locks after buying a house or moving in?
When a house changes hands, nobody can say how many copies of its keys are out there. The previous owner had some. So did their family, and maybe a cleaner, a contractor, a neighbor who watered the plants, or an agent along the way. Most of those people mean no harm, but you have no way of knowing who still holds a key, and a lock change makes the question irrelevant. For anyone searching for a locksmith for a new house, it is the most sensible task to finish in the first days of ownership, ahead of the painting and the furniture.
The same reasoning applies after any move. You may have just rented a place and have no idea who kept keys. A roommate may have moved out, or a relationship may have ended. A key ring may have gone missing, or a long remodel may have put keys in the hands of several workers. Whatever the reason, the goal is the same: the only keys that open your doors should be the ones you are holding.
Lake Balboa adds a wrinkle. The neighborhood is mostly postwar housing, with single-story stucco homes from the 1940s and 50s on modest lots, and original door hardware is still common in houses that have not been updated. That is a good reason to look at each lock before deciding anything. Some of that hardware is worth keeping and rekeying. Some has simply run out of life. Sorting out which is which is most of what a lock change call really involves.
Rekey or replace locks: which one do you need?
People say change locks and mean two different jobs. Rekeying keeps your existing lock hardware but changes the inside of each cylinder, so the old keys stop working and a new key takes over. Replacing removes the hardware and installs new locks. In both cases the old keys stop opening your door. What differs is what you are left with: the same knobs and deadbolts working on a new key, or entirely new hardware.
Here is how we usually think it through with a customer:
- Rekey when the lock is sound, turns smoothly, looks the way you want, and is a brand worth keeping. This is usually the more economical route, and it lets every door share one key.
- Replace when the hardware is worn, loose, corroded, or damaged, when a past break-in attempt left marks, or when a door has no deadbolt at all or only a flimsy one.
- Replace when you want something different: a higher-security cylinder, a new finish, lever handles, or an electronic lock.
- Either option works when you are unsure, and we would rather look at the door with you than guess over the phone.

Call (213) 577-1366How we handle a lock change, step by step
Here is what a typical lock change looks like when you call us.
- You call (213) 577-1366 at any hour. Tell us how many doors are involved, whether you have working keys, and what kind of home it is.
- We ask about the locks: knob, lever, or deadbolt, the brand if you can read it, and any trouble with sticking or loose handles.
- A technician drives out in one of our mobile vans. It is our own company on the job, not a dispatch broker passing your address along.
- Before touching anything, we inspect each lock and door: how the bolt lines up with the strike plate, how worn the cylinder is, and whether the door itself is part of the problem.
- We talk through rekey versus replace door by door, and we go over the scope and the cost before work starts.
- We do the work, either rekeying the cylinders or installing new hardware, then test every lock with the new keys, with the door open and closed.
- We hand over the keys, make extra copies if you want them, and answer any last questions before we leave.
What affects the cost of changing locks?
We do not post prices on this page, because a lock change is not one fixed job. A single back door and a whole house with a garage entry, a slider, and a front deadbolt are very different amounts of work. We explain the cost on the phone and again at your door, before we start. These are the things that move it:
- How many locks and doors are involved.
- Rekey or replace. Rekeying several locks to one key is usually the more economical route than replacing each one.
- The grade and brand of any new hardware. A basic knob, a heavy-duty deadbolt, a high-security cylinder, and a smart lock sit at very different levels.
- The condition of the door. Extra work such as adjusting alignment, repairing a worn bore, or adding a deadbolt where none exists takes more time and parts.
- How many keys you want, and whether all doors should work on a single key.
- The hour of the call. Nights, weekends, and holidays involve different logistics than a mid-week daytime visit.
- Your location and how far the van has to travel.

Call (213) 577-1366How do you know a locksmith is legitimate?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Whoever you hire, ask for the license number before work starts and check it. A legitimate company will not mind being asked. Be wary of anyone who is vague about who they are, quotes a very low figure over the phone and then changes it at the door, or arrives in an unmarked vehicle.
Lake Balboa is about 13 miles from our Westwood base, and it is one of the 140 cities and neighborhoods we serve across Los Angeles and Ventura counties. We treat it as a place we work in regularly, not a stretch on the map.
Changing locks in Lake Balboa: what the neighborhood looks like to a locksmith
Lake Balboa shares the 91406 ZIP code, and the housing varies enough that a lock change here rarely looks the same twice. Around the Balboa Boulevard corridor you find the postwar tract homes this neighborhood is known for. A common call is rekeying the original hardware on a house that has not been updated, where the front knob and deadbolt may be decades old but still mechanically solid. In that case rekeying is often the right move, because the lock still works and only the key situation needs to change. If the deadbolt is badly worn or the knob wobbles, we say so and recommend replacement instead.
Along the Victory Boulevard and Sherman Way corridors, the housing shifts toward apartment buildings. There are no high-rise or large HOA complexes in Lake Balboa, so these are generally smaller, older multifamily buildings, and the work often involves more than the front door. Security screen doors, mailbox locks, and shared entry hardware turn up regularly in buildings of that age, and a lock change on a unit may go hand in hand with mailbox lock replacement when a tenant moves in and the previous tenant's mailbox key is still out there.
The Vanowen Street corridor, the area around Birmingham Community Charter High School, and the streets on the Sepulveda Basin edge near Anthony C. Beilenson Park mix single-family homes, duplexes, and rentals. Households there change over regularly, whether through a sale, a new lease, or a family moving on, and each handoff raises the same question: who still has keys? If you are unsure what you have, a short call is enough for us to tell you what to expect.
Will dry heat and older wood doors affect a new lock?
Lake Balboa sits on the Valley floor next to the Sepulveda Basin, with hot, dry summers and somewhat damper air near the basin's irrigated parkland and lake. That seasonal swing causes modest sticking and alignment problems in older wood doors, and it matters for a lock change. A new lock cannot fix a door that rubs, and if a deadbolt bolt no longer lines up cleanly with the strike plate, a new cylinder will not make it smoother.
So we always check the door as well as the lock. Sometimes a lock that seems to be failing is actually a door that has shifted a little with the seasons. A strike plate adjustment, tightened hinges, or a corrected bolt alignment solves the problem. When we do replace hardware on an older door, we check the existing bore holes so the new lock sits properly and works easily. Where the door's condition is the real cause, we tell you plainly instead of selling you hardware you do not need.

Call (213) 577-1366Renters, landlords, and apartment tenants in Lake Balboa
If you rent, check your lease and talk with your landlord or property manager before changing anything. In many buildings the owner controls the locks, and a lock change without agreement can cause problems. If the owner approves a change, we can work from a written note or with the manager on the phone.
Landlords with units in the Sherman Way and Victory Boulevard buildings can benefit from a routine rekey between tenants, which is usually far more economical than replacing hardware every time. We cover that in more detail on our locksmith for landlords page. If a tenant is locked out rather than changing locks, that is a different job, handled under apartment lockout service.
What to have ready before we arrive
A little preparation makes the visit faster and the decisions easier.
- Gather every key you have for the property, including spares, garage keys, and keys for side gates.
- Count the exterior doors: front, back, side, garage entry, and any sliding door with a keyed lock.
- Decide whether you want every door on the same key. Most new homeowners do.
- Think about whether you want a new deadbolt installation on doors that currently have only a knob lock.
- Mention if you are curious about electronic options. We can talk through smart lock installation at the same visit.
- Plan on how many copies you need. We can cut them on site, and our key duplication page explains what to expect.
- Take a quick photo of each lock if you can, which helps us arrive with the right tools and parts.
Frequently asked questions
Should I rekey or replace the locks after buying a house in Lake Balboa?
If the existing locks are solid and operate smoothly, rekeying is usually the more economical route and keeps the hardware you already have. If they are worn, loose, damaged, or you want a different level of security, replacement makes more sense. Many postwar Lake Balboa homes still have original hardware, so we inspect each lock before recommending anything.
Do I need to change locks even if the seller handed me every key?
Yes, we would still recommend it. The seller can only give you the keys they know about. Past owners, relatives, agents, and workers may have had copies. Changing the locks means the only keys that work are the ones you now hold.
Will my old keys still work after the locks are changed?
No. After a rekey or a replacement, the old keys will no longer open the locks. That is the whole point of the job. If you want a few copies of the new key, we can make them at the visit.
Can all my doors be put on the same key?
In most cases, yes. Rekeying or replacing the locks so they share one key is a common request, particularly for new homeowners. Some hardware, especially very old or unusual brands, may limit what is possible, and if so we tell you what we can match and what should be replaced.
Can you change locks at night or on weekends in Lake Balboa?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, seven days a week, all year. After-hours calls can affect the cost, which we explain before work starts.
How long does a lock change take?
It depends on the number of doors and whether we are rekeying or installing new hardware. One door is much quicker than a whole house with a deadbolt, a garage entry, and a slider. We give you a realistic sense of the time once we have seen the doors.
Can I change the locks on a rental unit?
Check your lease and talk with your landlord first. The owner usually has the right to decide how the locks are handled. We can do the work when the owner or property manager approves it.
What if my older wood door sticks or does not line up?
That is common with older wood doors on the Valley floor, where seasonal swings affect fit. We check alignment during the visit. Sometimes adjusting the strike plate or hinges fixes the problem, and in other cases the door needs more work than the lock does. We tell you which it is.
