Rekey Locks After Tenant Moves Out in Covina
Short answer: Rekey after you hold lawful possession, not before. That means the tenant returned the keys or surrendered the unit in writing, or an abandonment or eviction process has finished; California bars lockouts meant to push a tenant out (Civil Code §789.3). Once the unit is yours again, call Julian's Locksmith at (951) 903-3193 and we'll rekey it in Covina.

The keys are on the kitchen counter, the tenant has gone, and you're standing in a quiet unit in Covina wondering whether the locks are finished business. They aren't, and the reason is simple arithmetic. You know how many keys you handed over. You don't know how many were cut at the hardware store, passed to a boyfriend, a cousin or a dog walker, or left in a gym bag. The ring on the counter proves nothing about the copies. Rekeying fixes that by changing the inside of each lock so old keys stop turning it. Julian's Locksmith does the work on site, usually in a single visit, and this page covers what to rekey, when it's safe to start and what to do about keys that never came back.
How this works in Covina
When you rekey locks after tenant moves out, the front door is only the start. Before you call, walk the property with the lease in hand and list every keyed point the tenant used: front knob and deadbolt, back or patio door, sliding door lock, garage side door, any security screen door, side gate padlock, shed, storage cage, mailbox, laundry or trash enclosure, and any keypad or smart lock code. Add anything the lease says the tenant received a key to, and anything an earlier occupant installed. Then sort the list into three piles: locks we can rekey, locks that are worn or damaged and need replacing, and codes or fobs that you or the HOA must clear. Doing that sorting in advance usually means one visit, one quote and one set of keys, with nothing discovered at the last minute. If the tenant held a key to something that isn't on your list, a quick conversation before the visit saves a return trip.
How we can help in Covina
- Finding every lock the tenant had a key to. Tenants use more keys than landlords remember: a laundry room key, an RV gate, a casita. Check the original move-in sheet, then look around the property for padlocks and keyholes in unlikely places, such as a pool equipment door. If you can't find a list, we can walk the exterior with you and count what we see.
- Rooms, ADUs and guest houses on an owner's property. If the tenant rented a backyard ADU, a garage conversion or a room in your own house, their key may also open your side gate, laundry room or shared entry. Rekey the unit itself, then decide which shared doors need the same treatment so a former occupant has no path to the rest of the property.
- Codes and app access the tenant shared. Garage keypads and gate codes tend to be forgotten. Reset the opener code, the community gate code if you control it, and any lockbox combination used during the tenancy. Codes are the invisible half of key control, and a former occupant who remembers one has the same access as one who kept a key.
- Move-outs that ended badly. If the tenancy ended in a dispute, a judgment or threats, the former tenant may be upset enough to use any key they kept. Rekey promptly once you regain possession, and consider whether a deadbolt upgrade or a door-frame check makes sense. If anyone's safety is at risk, call the police first. We handle the lock side.
- What to do with the returned keys. Keep the old keys until the new locks are tested, then decide. Some landlords hold them in an envelope with the move-out paperwork as evidence of what was returned, which is a fine habit. Others dispose of them. Either works once the cylinders have been re-pinned, because a rekeyed lock no longer recognizes them.
How Covina shapes the job
Family homes in suburban Covina usually have a front door, a back slider, a garage side door and perhaps a side gate, with kids and relatives who may have borrowed keys. The tenant's circle is bigger than the lease. Rekey all of those doors, ask the tenant to account for babysitters, grandparents and neighbors who had a key, and give the new family only the number of keys they'll actually use.
Apartment rentals around Vincent often belong to an owner of a few units rather than a management company with a locksmith on retainer. If your building uses a master key or someone else holds the keys to the common doors, tell us on the first call. We can rekey a single unit's entry lock without disturbing a master system if the hardware allows, and we'll say plainly when the building owner needs to be involved.
Inland heat is hard on rental hardware. Deadbolts bake in afternoon sun, plastic parts go brittle, and keys warp slightly when left in a hot car. When we rekey after a tenancy in Covina, we also check that the latch and bolt move freely and that the strike plate still lines up with a door that may have swelled or shrunk with the seasons. A smooth lock is a safer lock.
Common situations
- Think about a Saturday move-out: the tenant leaves at 9 p.m., the owner phones at 11:10, and we close at 11:30 that night. We'd be honest that a same-day finish is unlikely and offer the first Sunday slot, which starts at 6:30 a.m. Until then the unit stays shut, and nobody tucks a spare key under a flowerpot.
- A typical call: a landlord with a single townhome near Heritage Plaza Park texts that the tenant dropped three keys on the counter and left on the last day of the month. The next lease starts in nine days. We'd ask for the lock count, confirm ownership with ID and a tax bill, then rekey the front door, back slider and garage side door to one new key and leave two fresh copies behind.
- Say the tenant's boyfriend moved in quietly eight months ago and left with the tenant. Nobody listed him on the lease, and nobody knows whether he made a copy. The owner doesn't need to find out. We rekey the entry locks, the owner notes the date in the file, and the new tenant receives keys that no earlier occupant, listed or not, ever held.
- A small landlord calls in March about a tenant who left back in January. The unit sat empty, the locks were never changed, and showings are about to begin. Late beats never. We'd confirm ownership, rekey every cylinder before prospects tour the house, and cut keys for the property manager who is scheduling those tours, so the vacant months don't leave a loose end.
Step by step with Julian's Locksmith
- Confirm you hold possession. Write down the date and time you took possession and how: keys in hand, a signed notice, or a completed process. That one line protects you if the former tenant disputes anything later. Photos of the unit before we arrive add a second layer, and they also serve your deposit paperwork.
- Count what came back and what didn't. Lay the returned keys on a table and photograph them next to the move-in key sheet. Look for keys that seem newly cut, with brighter brass or different stamping from your originals; those may be copies. This isn't a legal test, just a prompt to rekey with confidence.
- Call with the unit details. A short, specific call saves everyone time. Tell us whether the locks are keyed alike now, whether any doors have a deadbolt only, whether a security screen door has its own key, and when the next tenant arrives. We'll say what we need from you at the door and give an honest arrival estimate.
- Show your authority at the door. Verification applies to rentals too, because a locksmith who rekeys without checking who's asking could lock out the real owner. If the tenant is still in possession, we stop and talk it through. California's Locksmith Act, overseen by BSIS, is why we ask; you can look up our license, LCO7891, at search.dca.ca.gov.
- Rekey, cut and test. We take each cylinder apart at the door, replace the pins to a new cut and reassemble. Every new key gets tried in every lock, and the old key gets tried to prove it fails. Locks that bind or feel loose are flagged before we leave, so you hear about them now instead of from the next tenant.
- Hand over keys and file the paperwork. Before leaving, we confirm every door latches, every key works and every extra, like a gate lock, is on the list. We write the date and the number of cylinders on the work record. A tidy file now makes next year's move-out a quick review instead of an archaeology project.
Pricing factors
- Brand, keyway and the lock's age. Age matters. A lock that has been rekeyed several times, painted over or chewed up by forced keys can feel rough, and fixing it may cost more than a new set. We'll show you the worn parts so you can see the reasoning behind a replacement recommendation.
- How many keys the next tenant needs. Each new key is cut and checked individually, so the number you request affects the total. One key per adult occupant plus a spare for you is a common starting point. If the lease specifies more, tell us. We state any difference in blank type before cutting anything.
- Add-ons that ride along on the same visit. Adding spare keys for a property manager, a lockbox swap or a deadbolt upgrade during the same trip generally costs less than a second visit later. We avoid selling you things you don't need, but a vacant unit is a convenient time to deal with hardware you've been meaning to fix.

Advice before you book
- Tell the incoming tenant that the locks were rekeyed on a given date, and put that in the move-in paperwork. It reassures them, reduces calls about who else has a key, and creates a clean starting point. We provide a dated record you can attach to the lease file.
- Test the old key as well as the new one. A properly rekeyed lock accepts the new key smoothly and refuses the old one outright. We try both at every door, because a lock that still accepts the old key hasn't been finished correctly, whoever did the work.
- Retire the lockbox code from the last vacancy. Lockboxes are for temporary access, and their combinations tend to circulate among agents, cleaners and contractors. Choose a fresh code for each use and take the box off the property once the new tenant has keys. A rekeyed door with a stale lockbox code is only half secure.
- Take a photo of each lock before and after the rekey, along with the returned keys laid out on a table. If a question ever comes up about what came back or when, a dated photo is stronger than memory. Store the pictures in a folder named for the address and the move-out date.
Common errors that cost time and money
- Assuming a returned set of keys means no copies exist. Keys are duplicated at hardware store kiosks in minutes, and a tenant, a roommate or a partner may hold one. The count you received tells you what came back, not what's out there. Rekey regardless.
- Rekeying only the front door. Tenants hold keys to the back slider, the garage side door, the gate and sometimes a shed. A new front-door key beside an old back-door key still leaves a way in. List every keyed point before the visit.
- Leaving old codes active in keypads and smart-lock apps. A cleaner, a friend or a former partner can hold a code long after the keys come back. Clear every user, reset the master code and note the date, just as you would for a rekeyed cylinder.

Frequently asked questions
The tenant returned all the keys. Do I still need to rekey?
Usually yes. Keys are copied at hardware stores in seconds, and you can't know whether the tenant, a roommate or a partner made one. Rekeying costs a fraction of what a security incident would, and it lets you tell the next tenant truthfully that no old key works. A restricted keyway lowers the copy risk, but it doesn't remove it.
What about the mailbox key?
Mailbox locks are usually the post office's or the HOA's responsibility. Individual doors on a cluster box are often replaced by the local post office on request, while a standalone box on a house is yours to rekey or replace. We can handle standalone mailbox locks during the same visit. For cluster units, ask your HOA or the post office first.
Can I rekey the locks myself?
You can, and plenty of landlords do. Kwikset SmartKey locks can be rekeyed by the owner with a tool and a working key, and pin kits work on standard cylinders. The risk is a missed lock or a mismatched pin that leaves the old key working. We're happy to correct a DIY job, and we test the old key at every door.
What if the tenant didn't return any keys?
First confirm the tenancy has ended and you hold possession. If the tenant simply left without a word, California's abandonment procedure (Civil Code §1951.3) involves written notice and waiting periods, so check with an attorney. Once the unit is legally yours again, we rekey every lock and give you fresh keys, and the missing ones become useless.
How long does it take to rekey a rental after a move-out?
A typical house with three or four keyed points is usually finished in one visit, though the time depends on the lock count, the brands and any damaged parts. We give you an honest estimate when you call rather than a fixed promise. If a lock proves to be worn or unusual, we explain before changing the plan.
Should I rekey or replace locks after tenant moves out?
Rekey in most cases. It changes the key without replacing hardware that works fine, and it costs less. Replace a lock that's worn, damaged, discontinued or below the standard you want. We test each cylinder, tell you honestly which category it falls into, and price each choice separately so you can decide.
How far is Covina from your base?
Covina is about 39 miles from our San Bernardino base, roughly 45 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.
