Changing Your Locks in Pomona, Explained by a Locksmith
Short answer: Changing locks usually takes one visit. We count every keyed door, including the garage entry, side gate and security screen door, decide door by door whether a rekey or new hardware makes sense, and quote it. Then we do the work and test each key with the door shut. You leave with fresh keys and a clear list of who holds them. Call (951) 903-3193.

New keys at closing aren't new locks. When escrow closes on a Pomona home, you receive whatever keys the seller could find, and you inherit every copy the seller couldn't. Builders' crews, showing agents, dog walkers and relatives may all have handled them over the years. That's why we suggest you change locks, or at least rekey them, during your first week in the house. If the home came with a keypad or smart deadbolt, the job also includes clearing old user codes, removing the previous owner's app access and resetting any hub, because a keypad remembers codes long after the people who set them have moved away.
People change locks in Pomona for clear reasons: a home purchase, a breakup, a break-in, lost keys, worn-out hardware, or an upgrade to something that suits the household better, such as a keypad for a family with several teenagers. The real question is whether to rekey or replace. Rekeying keeps your hardware and changes the keys. Changing the lock replaces the hardware itself, so you can pick a different brand, grade or feature set. Renters make up close to half of Pomona households, so tenant law is part of the picture. California Civil Code Section 1941.3 puts a basic duty on landlords: a working deadbolt on the main swinging entry door of a rental, plus window security devices. If you want to swap the locks yourself, most leases require your landlord's approval and a copy of the new key. Civil Code Sections 1941.5 and 1941.6 require a landlord to change the locks within 24 hours of a tenant's written request in certain situations involving a protective order or similar documentation. Whoever you are, we ask for ID and proof of tenancy or ownership, quote before we start and haul away the old hardware if you want it gone.
What to expect in Pomona
People change locks for reasons that have little to do with hardware. A spare key went missing from the planter. A contractor's crew finished the kitchen remodel. A caregiver, house sitter or ex kept a copy. Keys were in a purse that was stolen along with an ID showing the address. In each case the hardware works fine, but key control is broken: you no longer know how many working keys exist. A rekey resets that count to zero, and from there you decide who gets one. If keys tend to multiply in your household, consider a restricted or patented keyway from a manufacturer such as Medeco, Mul-T-Lock or ASSA Abloy, where blanks are controlled and copies require your authorization. For a Pomona rental or a home with rotating help, a keypad deadbolt can be better still, because removing a code takes seconds and nobody needs a locksmith to do it. Either way, we'll help you count the keys and track who has them.
Work included on a typical visit
- Rekeying your existing locks. Choose a rekey when the locks are sound and your only problem is unknown keys. It suits move-ins, departed roommates, lost keyrings and contractor turnover in Pomona. It won't fix a sticky latch, a cracked housing or a flimsy builder-grade knob, so we point out any lock that deserves replacing instead of pinning it and hoping.
- Handlesets and front-door entry sets. Front doors often carry a handleset: a deadbolt above and a thumb-latch or lever grip below, bolted through the door at two points. Brands drill those through-holes at different spacings, so a straight swap may leave an old hole exposed. We check the spacing first and recommend a matching set or a cover plate before anything comes off.
- Smart lock swaps and code resets. Changing to a smart deadbolt such as a Schlage Encode, Kwikset Halo or Yale Assure lets you add and delete users without cutting new keys. We install it on your existing bore, confirm the bolt throws fully without motor strain, pair it with your app, and set up codes. The backup key cylinder gets keyed to your house key.
- Strike and frame reinforcement. After forced entry, we assess the jamb, door edge and hinge screws before installing anything. A split jamb may need a repair kit or a carpenter, and we're honest about where locksmith work ends. When the frame is sound, a reinforced strike and longer hinge screws make the new lock worth what you paid for it.
- Urgent safety lock changes. Safety lock changes include small extras that make a real difference: rekeying the garage entry and side door too, resetting keypad and garage opener codes, and checking whether sliding doors need a secondary bar or pin. We describe the work on a dated invoice, which some tenants and their advocates find useful as documentation.
What's different about Pomona
Older homes often hide more keyed locks than people expect: original mortise locks, service porch doors, and decades of add-on deadbolts. Before you change locks in an older Pomona house, we check whether original hardware can be rekeyed and serviced instead of replaced, which preserves period trim and avoids filling oversized door pockets. Where doors were bored at odd sizes or old jambs won't hold a modern strike, we explain the fix honestly, including when a carpenter should go first.
Long commutes mean long empty hours at home, and a lock change for commuters should account for that. In Pomona, many households add a smart deadbolt that reports its status, so you can confirm the door is locked from the office. We can schedule a lock change early, starting at 6:30 a.m. every day of the week, so you don't lose a full day of work.
Apartment lock changes depend on who controls the keys. Many complexes use a master key system or interchangeable cores, and a tenant who swaps a lock can break management's ability to enter in an emergency. In Pomona apartments, we usually work with the office: re-pinning a cylinder within their system after turnover, or responding quickly when a tenant's protective order triggers California's 24-hour lock change rule.
Example situations
A young couple closes escrow on a ranch house in North Pomona. The front door has a 1980s brass knob set with a pitted finish and a deadbolt that sticks every summer afternoon. Rekeying would work, but they would rather start fresh. We check their closing papers and ID, remove both locks, fit a Grade 2 keypad deadbolt and a matching lever on the same door preparation, and set a code for each of them. The old hardware goes in our bin.
- A typical estate call: siblings inherit their parents' house and realize that neighbors, caregivers and a cleaning service all had keys at some point. The executor shows us letters testamentary and a photo ID. We'd rekey the doors to a new key, cut a set for each sibling who needs access, and replace a corroded side-gate padlock that no longer turns.
- Suppose a purse is stolen from a car at a gym, and inside are house keys and a driver's license showing the address. The owner cancels the cards first, then calls us. Because a stranger now holds both the keys and the address, we'd treat it as same-day work: rekey the front and garage entry doors first, then the remaining locks, and change the garage keypad code.
- Picture a duplex owner in the 91768 ZIP code with one tenant moving out on a Friday and a new one moving in Monday. We'd schedule the turnover rekey for Sunday morning, replace a worn knob set with a lever and deadbolt, confirm the bolt throw meets California's rental deadbolt rule, and leave a labeled envelope of keys for the owner.
How the visit works
- Tell us the reason and count the doors. On the phone, we ask a few practical questions: how many doors, which brands, whether anything is damaged or sticking, and whether you rent or own. Photos of each lock help. The answers shape the quote and tell us whether to bring extra hardware or a high-security cylinder to your Pomona address.
- Verify residence or ownership. Before we change locks, we confirm you have the right to authorize it. Owners show photo ID plus something linking them to the address, such as a closing statement, deed or utility bill. Tenants show ID and a lease, and we may ask about landlord consent. It's how a licensed locksmith should work.
- Inspect each lock and choose rekey or replace. We measure backset, bore and door thickness wherever new hardware is on the table, because a lock that doesn't fit the existing prep means drilling, filler plates or an extra trip. Measuring first means the new lock goes into holes it was designed for, and your door edge stays clean.
- Re-pin or install the hardware. Most of the work happens at the door and in the van. New keys are cut to code on our machine, cylinders are pinned at a bench, and hardware comes from stock. If a special finish or high-security cylinder isn't on hand, we secure the door with a rekey and come back to finish.
- Test every key on every door. Testing includes the locks you won't use daily: the garage entry, side gate and screen door. We also turn each old key in each re-pinned cylinder to confirm it no longer operates. If you left a spare with a neighbor or in a car, bring it so we can test that one as well.
- Hand over keys and records. You get the new keys, a count of how many were cut, and an itemized invoice. We suggest writing down who receives each copy. If you rent, the landlord or manager typically gets one under your lease. Old keys can go in the trash; they no longer fit anything on the property.
Pricing factors
- Rekey versus new hardware. Some hardware changes the math entirely. Kwikset SmartKey cylinders can often be reset with a tool rather than disassembled, and Euro cylinders swap with one screw. A mortise lock with a seized body, on the other hand, may need parts that take time to find. Your quote reflects the actual hardware, not a flat guess.
- Number of doors and cylinders. Larger jobs usually cost less per lock because there's one trip and one setup. If you're thinking about changing the main house now and the casita or detached garage later, it often makes sense to do them together while we're already set up at your Pomona property.
- Hardware grade, brand and finish. Smart locks and high-security cylinders sit at the top of the hardware range. A keypad deadbolt adds setup and app pairing time; a patented cylinder adds a controlled blank and key registration. Both buy something real, easy code changes or tight key control, so decide which problem you're actually trying to solve.
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 Pomona.
Common errors that cost time and money
- Over-tightening the through-bolts. Cranking the screws that hold a knob, lever or deadbolt together squeezes the mechanism and makes the latch or bolt drag. The lock feels solid at first and then starts sticking, especially when heat swells the door. Snug and even is correct; the door should close with one easy push.
- Assuming a smart lock means no rekey is needed. Retrofit models replace only the inside half and keep the old exterior cylinder, and full smart deadbolts still have a keyed override. If an old key turns that cylinder, the door opens no matter how many codes you delete from the app.
- Installing a new lock into a weak strike. A Grade 1 deadbolt anchored by short screws into a thin pine jamb fails at the jamb. When you change locks, upgrade the strike and use long screws into the framing behind it, or the new hardware mostly just looks nicer.
Practical tips before you call
- Before you change locks, walk the property and count every keyed cylinder: front deadbolt, front handle, garage entry, back door, side gate, security screen door, mailbox and sheds. Write them down with the brand names. It takes five minutes, makes your quote accurate, and keeps you from forgetting the one lock an old key still opens.
- Test your deadbolt with the door closed. Turn the thumbturn slowly; if you feel it drag, or you have to push or lift the door, the strike is out of line and the bolt may not be fully extended. A partly thrown bolt is far weaker. Mention it when you call so we can realign it during the lock change.
- Include the security screen door when you change locks. These doors usually have their own deadbolt or deadlatch, and many accept a cylinder that can be rekeyed to your new house key. On hot afternoons plenty of families leave the wood door open for airflow and lock only the screen door, so that cylinder matters as much as the deadbolt.
- If you rent in Pomona, ask your landlord in writing before changing anything, and offer a copy of the new key. A short email creates a record. Most leases require consent, and California gives landlords a right to enter with notice, so a lock they can't open causes friction. Safety situations covered by Civil Code 1941.5 follow their own rules.

New or replacement locks in Pomona?
Call (951) 903-3193 and tell us which doors and what kind of hardware you have in mind. If you already bought the lock, keep the box handy so we can check it fits the door, and we'll quote the install before any work starts.
Frequently asked questions
Can you change my mailbox or gate lock at the same time?
Gate locks and padlocks, yes, and many can be keyed to your house key. Mailboxes depend on ownership. A wall-mounted or post box you own can usually take a new cam lock. A cluster box unit may belong to the Postal Service or to your HOA or property manager, and the owner decides who changes it. We'll help you sort out which applies in Pomona.
Can a renter change the locks in California?
Usually not without the landlord's consent. Most leases require it, and the landlord has a right to enter with proper notice. Ask in writing, offer to pay, and give the landlord a key. The exception is a tenant protected by a qualifying court order or police report: if the landlord doesn't change the locks within 24 hours of a written request, the tenant may have them changed.
Is a locksmith required to be licensed in California?
Yes. Locksmith companies in California must be licensed by the Bureau of Security and Investigative Services under the Locksmith Act, Business and Professions Code section 6980 and following. Julian's Locksmith holds license LCO7891, and you can verify it at search.dca.ca.gov. Ask any company for its number before work starts; a refusal to share it is a warning sign.
Will you install locks I bought myself?
Yes. We install customer-supplied hardware and rekey it to your house key so you don't end up with a separate key for one door. Before buying, check that it's rated for exterior use, fits your door thickness and backset, and matches your existing bore. Have the box and every part at the door; strikes and screws go missing surprisingly often.
What does California Civil Code 1941.3 require for rental locks?
It requires landlords to install and maintain an operable deadbolt on each main swinging entry door of a dwelling unit, and a newly installed bolt must extend at least 13/16 inch when locked. Windows designed to open need working locks or security devices, with exceptions for certain window types and positions. Tenants must tell the landlord when a lock stops working, and the landlord must then fix it within a reasonable time.
Do I need to change locks after buying a house?
You should, and it's one of the first things we recommend after closing. The sellers, their relatives, past contractors, cleaners and showing agents may all have had keys, and nobody can account for every copy. A rekey of sound hardware is usually enough. Add a factory reset for any smart lock and clear the garage opener's memory while you're at it.
How far is Pomona from your base?
Pomona is about 32 miles from our San Bernardino base, roughly 38 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.
