What do landlords and property managers actually need from a locksmith?
A homeowner calls a locksmith once in a while. A landlord calls constantly, and for predictable reasons: a tenant moves out and nobody can say where all the keys went, a lock sticks in the summer heat, a resident is locked out on a Friday night, a mailbox lock fails, or a gate latch stops catching. None of these is dramatic on its own. Together they eat hours every month when each one is handled as a fresh scramble.
This page is for owners of single rentals, small multifamily buildings, and managers who look after several properties in Northridge. The goal is a simple working arrangement: you know who to call, we know how your doors are keyed, and the routine work gets done without drama.
We run a storefront at 10740 Wilshire Blvd in Westwood, plus mobile service vans, and Northridge is about 20 miles from that base. We have been in business since 1987, and David, the owner and lead technician, oversees how the work is done.
How does tenant turnover rekeying work?
Rekeying changes the internal pins of a lock you already own so the old keys stop working and a new key takes over. The hardware stays on the door. For most turnovers this is the more economical route compared with swapping every lock, and it gives the next tenant a door that previous tenants, roommates, and their friends can no longer open. Here is how a typical turnover visit goes:
- You send us the address, the unit numbers, and which locks are involved: entry knob or lever, deadbolt, patio slider, side gate, mailbox, laundry or storage room.
- We look at each lock on site. A rekey only makes sense if the lock still works properly, so we check that the bolt throws smoothly and the latch lines up with the strike.
- We rekey each cylinder to the new key. If you want the entry lock and deadbolt on one key so the tenant carries a single key, we set them up keyed alike.
- We test every lock with the door open and closed, and with the key from both sides where that applies.
- We hand over the keys the way you want them, with the spare count agreed ahead of time.
- We tell you what we noticed, such as a worn deadbolt, a loose strike plate, or a warped slab, so you can decide on repairs before the next move-in rather than after the first complaint.

Call (213) 577-1366When is replacing the lock better than rekeying?
Rekeying is not always the right call. If a lock is worn out, damaged, mismatched with the others in the building, or you want an upgrade, replacement makes more sense than rekeying a tired cylinder. High-turnover units are the usual example: a lock that has been keyed and re-keyed through many tenants and handled by many hands can loosen up inside.
We will tell you plainly which one we think is worth doing. You can read more about the process on our lock rekey service page, and the answer often differs door to door within the same building.
Should a Northridge rental building use a master key system?
A master key system lets one key open many locks while each tenant's own key opens only their door. For a manager, that usually means one key for utility rooms, laundry rooms, storage, gates, and vacant units, instead of a ring that gets heavier every year. Our master key system page covers the mechanics in more detail.
It is not free of tradeoffs, and we would rather say so up front:
- Planning comes first. The hierarchy, meaning who can open what, should be written down before any key is cut, because changing it later means rekeying.
- The master key becomes the most important key you own. If one is lost, the affected locks need to be rekeyed, so control who gets one.
- A poorly designed system can weaken security. A well-planned one keeps the extra complexity inside the locks where tenants never see it.
- For a duplex or a small building, keyed-alike locks per unit and a short list of keys is often simpler and fully adequate. A full master system is worth it when you have enough doors that the key ring itself has become the problem.
- Stamping a key 'do not duplicate' does not stop copying by itself. Real key control comes from restricted key blanks, and we can explain which options fit your property.
What should a lockout policy for tenants look like?
Decide your lockout policy before the first call comes in, because the first call tends to arrive at an awkward hour. A clear policy saves you from making rules while a tenant is standing on the porch.
The questions worth answering in writing:
- Who is allowed to request a lockout service: the tenant, the manager, or both?
- How will the person be verified as a resident or as someone authorized to act for the owner?
- Who pays: the tenant, the owner, or a split depending on the situation?
- What happens after hours? Do tenants call you first, or call us directly?
- Is a lost key a rekey event, and who decides that?

We answer around the clock, every day of the year.
Call (213) 577-1366How do we handle tenant lockouts without opening the wrong door?
When someone calls from outside a rental, we ask for identification and for some reasonable proof they belong at that address, or authorization from the owner or manager. We will not open a door just because someone says it is theirs. That protects your tenants and you.
Most apartment lockouts can be handled without damaging the lock. If a key is broken in the lock, or the lock itself has failed, we will say so and explain the options. Our apartment lockout page explains what the visit involves. Our phone line, (213) 577-1366, is answered around the clock, every day of the year, so a lockout at 2 a.m. gets the same answer as one at noon.
What affects the cost of landlord locksmith work?
We do not quote numbers on a web page, because the honest answer depends on your doors. These are the real factors:
- How many locks are involved. Rekeying ten cylinders in one visit is a different job from ten separate calls.
- The brand and condition of the existing hardware. Some locks rekey easily, and some are worn enough that replacement is the better option.
- Rekey versus replace, and the grade of hardware you choose if you replace.
- Key type. Standard keys are simple to duplicate, while restricted keyways and master systems involve more planning and more parts.
- The complexity of a master key system: how many levels, how many doors, and how much records work is involved.
- Scheduled versus urgent work. A planned turnover during working hours is usually the lighter-cost option compared with an after-hours emergency.
- Time of day and travel distance to the property.
What is different about locks in Northridge rentals?
Northridge is not uniform, and the housing stock decides a lot about what we find on the doors. Around the CSUN campus area there are student-oriented apartment complexes with very high turnover. Semester move-in and move-out are when lockouts bunch up, and hardware that gets used hard by many short tenancies wears faster than hardware in an owner-occupied home.
Much of Northridge's multifamily stock was repaired or rebuilt after the 1994 earthquake, which the neighborhood gave its name to. The result is that door frames and hardware vary widely in age, even within one property. We never assume every unit in a building has the same lock. We check each door, and if your building has a mix of brands, we can help you standardize gradually as locks come up for replacement.
Out in the 1950s-60s ranch tracts, such as those in the Devonshire Street corridor, many rentals are single-family houses where rekeying between tenants is the most common job. Larger semi-rural lots toward the Sherwood Forest area on the western edge often mean more doors to deal with: side gates, back doors, and outbuildings.
Climate matters too. North Valley summers are long and hot, with Santa Ana wind events in the fall. Sun-exposed doors expand in the heat and start to stick or bind, and a latch that fights the strike plate wears out the lock faster. A quick adjustment during turnover often prevents a service call later.
We work across both Northridge ZIP codes, 91324 and 91325, and along the main corridors: Reseda Boulevard, Nordhoff Street, Tampa Avenue, and Devonshire Street, as well as the Northridge Metrolink station area and the Northridge Fashion Center district. If you also own mixed-use or commercial space, we handle that side too, including retail lock and master-key work, medical office rekeys near Northridge Hospital Medical Center, and business doors along Reseda Boulevard. See our commercial locksmith page for details.

Call (213) 577-1366What about mailboxes, gates, and shared doors?
Common areas get overlooked until they fail. A cluster mailbox lock that no longer turns, a pedestrian gate that does not latch, or a laundry room door that has been propped open for months are all security problems, and tenants notice them before owners do.
We handle mailbox lock replacement and gate lock repair as part of the same relationship, so you do not need a separate vendor for each. For larger properties we can also discuss access control for shared entries, though keys are often the more practical choice at smaller buildings.
Why call Wilshire Lock & Key for your properties?
Property work depends on reliability more than anything else. Here is what we offer, without exaggeration:
- In business since 1987, so we have seen most lock types and building situations that turn up in rentals.
- A storefront in Westwood and mobile vans, so we are a real local company with a real address and not an answering service.
- One company from the first call to the finished door. We do not pass your job to a dispatch middleman or a stranger subcontractor.
- David, the owner and lead technician, oversees the work.
- Phone answered 24 hours a day, 7 days a week, year-round at (213) 577-1366.
How do we set up a standing arrangement for your portfolio?
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith you hire for the license number before work begins. That applies to every company, including us. Beyond that, setting up a routine is straightforward:
- Call (213) 577-1366 and tell us how many properties and units you manage in Northridge and the surrounding area.
- We walk the properties or review photos of the doors to see what hardware is in place.
- We agree on a keying plan: keyed-alike per unit, a master system, or a mix.
- You write down your lockout policy, and we make sure we know who is authorized to call.
- From then on, turnovers, lockouts, and repairs come to one place. You can also see our other service areas on our locations page if you manage properties outside Northridge.
Frequently asked questions
Should I rekey after every tenant moves out?
We recommend it, because you cannot know how many copies of a key exist. It is your call, but rekeying is usually the more economical way to make sure only the current tenant's key works.
Can you handle several units in one visit?
Yes. Grouping doors into one visit is usually more efficient than separate calls, and it is often the lighter-cost way to do turnover work. Tell us the addresses and units ahead of time so we can plan.
Who can authorize a lockout at a rental?
The tenant can request it with proof they live there, and an owner or property manager can authorize it on their behalf. We ask for identification and reasonable proof before opening any door.
Can you help set up a key schedule for a master key system?
Yes. We help plan which keys open which locks and can write that up for you. Keep your own copy, because a good key record is as useful as the locks themselves.
Are smart locks a good idea for rentals?
They can be. A code can be changed between tenants without cutting new keys. Batteries, tenant habits, and hardware condition all matter, though, so we talk through the tradeoffs for your building before recommending them.
Do you work on short-term rentals?
Yes. Frequent guest turnover creates its own key and code needs, and we cover those on our vacation rental locksmith page.
Our building has mismatched locks from different repairs. Can you standardize them?
Usually, yes. In Northridge, hardware varies widely in age because so much was repaired or rebuilt after 1994. We check each door and can standardize over time, replacing locks as they wear out instead of all at once.
Will you give me a price over the phone?
We will explain what drives the cost and what we need to see, but a responsible answer depends on the hardware and the number of doors. We explain the cost before we start the work.
