New Address in Downey? Rekey Locks after Moving
Short answer: Renters can usually rekey locks after moving, but read the lease first. Most California leases require the landlord's consent and a working key for the owner. Ask the manager whether the unit was rekeyed since the last tenant; if not, request it in writing or get approval to arrange it. We check your lease and ID in Downey before touching a cylinder.

A lot of people who look up how to rekey locks after moving are renters, and renters have one step owners don't: the lease. Many California leases allow a rekey only with written permission and require that the landlord keep a working key. That approval is usually easy to get, especially when you offer to pay and drop off a copy. Rekeying leaves the landlord's hardware in place, which makes it the friendliest way to secure a rental whose locks you didn't choose. We serve renters and owners throughout Downey, verify ID along with your lease or deed, and price the job before we pick up a tool.
What to know first in Downey
Think about everyone who might still hold a key to your new place. In a rental, that list usually includes the last tenant, anyone they gave a spare to, the property manager, past maintenance techs, carpet cleaners and painters who worked the turnover, and perhaps a leasing agent who showed the unit. In a home that changed owners, add the sellers, their adult kids, a housekeeper, a pool service, contractors and the agents who used the lockbox. Then add copies made at hardware-store kiosks, which nobody tracks. A stamp reading Do Not Duplicate on a key doesn't stop a determined person from finding a shop that will copy it. None of these people need bad intentions for the situation to be a problem; keys get lost, sold with old cars, or left in junk drawers that someone else empties. You can't collect them all, but you can make them useless. That's what a rekey after a move does: it changes the combination each lock answers to, so every key on that long, invisible list stops working at once, and the only working keys are the ones you're holding when we leave.
Work included on a typical visit
- Whole-home rekey for owners. Owners who just moved in can have every exterior lock rekeyed in one visit: front, back, garage entry, side doors and any keyed patio lock. We carry pins for the common residential brands, so most homes are finished on site. If you closed months ago and are only now settling in, the job is exactly the same.
- Security screen doors and sliders. Southern California homes lean on steel security screen doors and sliding patio doors, and both get ignored at move-in. Many screen doors carry their own keyed deadbolt, and former occupants still have those keys. We rekey or replace that cylinder, often matching it to your house key, and check the slider's latch.
- Garage, side gate and outbuilding locks. The door from the garage into the house is the one most often left unlocked, and it frequently uses a different key than the front. We rekey it with the rest. Side-gate padlocks and shed locks usually aren't worth re-pinning, so we suggest replacing them with rekeyable padlocks cut to your key.
- Smart lock and keypad takeover. A keypad or smart lock inherited in a move may still hold the old occupant's codes, phone access or admin account. We help you reset it, register it under your own account and set fresh codes. Most also hide a keyed backup cylinder, which we rekey so an old physical key can't bypass the electronics.
- Fixing locks the move knocked loose. Locks that worked during the walkthrough sometimes bind a week later after the door was propped and slammed. A deadbolt that needs a shoulder push to lock usually ends up left unlocked. We realign strikes, replace stripped screws with longer ones driven into the framing, and test from both sides.
What's different about Downey
Apartment move-ins come with a property manager who usually controls the locks. Ask whether your unit was rekeyed since the last tenant and get the date. Many complexes use master keys or interchangeable cores, so a rekey should go through management or come with their written approval. In Downey, we work with tenants and managers alike, and we leave a key for the office whenever the lease requires one.
A family move brings new key holders almost immediately: kids, grandparents, a babysitter, the neighbor who'll feed the cat. Rekeying after the move gives you a clean starting count. We can key the front, back and garage entry doors alike so younger kids carry one key, and suggest a keypad deadbolt on the door they use most so nobody needs a key under the mat.
Older homes arrive with layers of hardware: a mid-century mortise lock, a deadbolt added decades later, a screen door bolted on after that. Each layer means more people who once held keys. When you rekey locks after moving into an older house in Downey, we check every cylinder's keyway, re-pin what's practical and replace pieces too worn to trust. Original glass knobs and mortise sets can often stay with a fresh cylinder.
Example situations
- Consider a renter whose new place has a keypad deadbolt, and the manager can't remember its programming code. Rather than replacing it, a locksmith can often return the unit to factory settings with the landlord's approval, set new user codes and rekey the backup cylinder hidden behind the keypad. The renter keeps a code, and the landlord gets the master code in writing.
- Consider a move into an older bungalow near South Downey with an original mortise lock on the front door and a newer Kwikset deadbolt above it. The vintage mortise cylinder can often be re-pinned too, though some use uncommon keyways that need special blanks. A locksmith would check both, rekey what's practical, and say honestly whether the antique deserves a new cylinder.
- Say a family of five leaves an apartment for a rented three-bedroom house off I-710. The front door, garage entry, back door and side gate each take a different key. With the owner's written okay, a locksmith could re-pin the three door locks to one key and replace the rusted gate padlock with a rekeyable one cut to match, leaving the family a single key and the owner a copy.
- Consider four students moving into a rental house near Bob's Big Boy Broiler who find a drawer of unlabeled keys left by last year's group. The landlord agrees to a rekey as long as the household pays and he receives a copy. Since nobody knows which old keys fit which doors, re-pinning every exterior lock and cutting five new keys is faster than testing the whole drawer.
How the visit works
- Tell us about the move. Call (951) 903-3193 with your move-in date, how many exterior doors you have, and whether you rent or own. Photos of the locks help us load the right pins and cylinders. If movers are coming, mention their arrival time so we can work around them.
- Show that you belong there. Moving into a relative's home or an ADU without a lease of your own? The property owner can authorize the work by phone or in writing, and we match that authorization to ownership records when needed. It's a short step that keeps anyone from rekeying a house they shouldn't.
- Walk the property and count cylinders. We walk every door with you, noting each lock's brand, keyway and condition and pointing out anything worth fixing. Hidden extras show up here: a keyed screen door, a garage side door, a padlocked meter gate. You approve the final list and price before we start.
- Re-pin each lock. Each cylinder comes out of the door, the plug slides free, and the old key pins are swapped for new ones sized to your new key. We clean and lubricate the cylinder while it's open. Standard residential locks take only a few minutes apiece once they're out.
- Reset codes and test every door. Before we pack up, you try every key yourself. It's the only way to know they feel right in your hand, not just ours. We also clear old keypad codes and set new ones with you, so nobody from the previous occupancy can punch their way in.
- Hand off the keys and the record. You get your new keys, a note of which key fits which door, and the count of copies we cut. Renters get an extra key for the landlord when the lease requires one. File the record with your lease or closing papers; it helps if a key goes missing later.
What affects the cost
- How many cylinders you have. An apartment with one deadbolt and one knob is a small job. A detached house with a garage, a side door, two screen doors and a keyed patio lock can run to eight or ten cylinders. Count yours before you call, and the quote you get will be realistic.
- Brands, keyways and lock condition. Mixed hardware adds time. When the front door is Schlage, the back door is Kwikset and the garage entry wears a no-name brand, getting everything onto one key may mean replacing a cylinder. We tell you which locks can be matched before quoting any extra parts.
- Extra keys and key control. If your lease requires the landlord to hold a key, or your HOA wants one for emergency access, add those to the count. Cutting them during the rekey means every key comes from the same fresh combination and works the first time someone tries it.
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 Downey.
Mistakes to avoid
- Swapping locks as a renter without permission. A lease that requires consent can turn a security upgrade into a dispute or a deposit deduction. Get approval in writing, rekey instead of replacing hardware, and hand over the copy your lease calls for. A five-line email now beats an argument over the deposit later.
- Waiting until every box is unpacked. By then a long line of helpers, installers and delivery drivers has passed through, and furniture blocks the doors we need to reach. The rekey is easiest and most useful before or right after the truck, not as a someday project that slides into next month.
- Assuming the landlord rekeyed. Some owners rekey at every turnover, and some only bother when a tenant leaves on bad terms. Unless you have a date or an invoice, you don't actually know, and a manager's best guess is still a guess. Asking costs nothing, while guessing wrong could mean a former tenant's key still opens your door.
What to do before we arrive
- Renters, keep the landlord's consent with your lease. A short email saying the landlord approves a rekey and will receive a copy is enough. If anything comes up at move-out, you'll have proof the work was authorized and that you supplied the key.
- New-resident mail is full of welcome packets, replacement cards and account paperwork, and a former occupant's mailbox key may still fit. If the box is yours, change the lock in the same visit as the doors. If it's a cluster unit, ask who owns it before anyone touches it.
- Walk the property once looking for hidden keys: under rocks, on top of door frames, inside meter boxes, behind shutters. Previous occupants leave them behind more often than you'd think. Finding even one is a strong reason to rekey, even if you'd decided you didn't need to.
- Moving in summer? Heat swells doors and can make deadbolts bind in the afternoon. If a lock feels stiff at four o'clock but fine at breakfast, the strike may need adjusting rather than the lock replacing. Mention the timing when you book so we check it.

Frequently asked questions
What do I need to show before you rekey?
Photo ID plus proof that you live there or own the property. Renters can show a lease in their name and, if the lease requires it, the landlord's consent. Owners can show a deed, closing statement or recent tax bill. If you're living in a family member's property without a lease, the owner can authorize us directly. We verify before touching any lock.
How much does it cost to rekey locks after moving?
It depends on how many cylinders you have, the brands, whether any locks need repair or replacement, any smart lock work, and how many keys you need. We don't post prices online, but we do give a firm quote before starting, once we've counted your locks. Call (951) 903-3193 with your door count and lock brands for a realistic estimate in Downey.
Can I rekey just the front door after moving?
You can, but it rarely makes sense. Previous occupants could easily have keys to the back door, garage entry or side gate as well, and any one of those gets them inside. If the budget is tight, prioritize doors that open directly into living space and add the rest later. We'll quote both options in Downey so you can choose, and a later visit can match the remaining locks to the same key.
I moved in months ago and never rekeyed. Is it too late?
Not at all. A rekey works the same whether you moved in last week or last year, because old keys don't expire. If anything, waiting gives you more reason, since you've probably handed out a spare or two yourself by now. We'll rekey every exterior lock, cut a fresh set of keys and help you keep track of who holds them from here on.
How long does a move-in rekey take?
Most homes and apartments are finished in one visit. A standard residential cylinder takes only a few minutes once it's out of the door, so the total depends on how many locks you have, whether they share a brand, and whether any need repair. A small apartment is quick; a house with eight or ten cylinders plus a smart lock takes longer.
My apartment uses a master key. Can my unit still be rekeyed?
Yes, but it should go through management or have their approval. Rekeying a master-keyed cylinder without the system's keying records can lock maintenance out and disrupt the building's key system. Many complexes have a locksmith on file who can change your unit's key while keeping the master working. If management authorizes us and shares the keying details, we can handle it.
How far is Downey from your base?
Downey is about 59 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.
