Changing Your Locks in Covina, Explained by a Locksmith
Short answer: To change locks in Covina, you have two real options: rekey the cylinders you already have so every old key stops working, or install new hardware. Rekeying fits when the locks are sound and you like them. Replacement fits worn, damaged, mismatched or low-grade hardware. Julian's Locksmith does either on-site after verifying that you live at or own the property.

Renting in Covina doesn't mean you're stuck with keys that a dozen past tenants may have copied. California law puts the basic lock duties on the landlord: an operable deadbolt on each main swinging entry door and working locks on windows that open. If you want a lock change beyond that, the cleanest path is a short written request to your landlord or manager. Many agree, especially when you offer to cover the work and hand over a copy of the new key. Julian's Locksmith can talk with both of you, confirm the tenancy, and change locks so the old keys stop working the day the work is done.
To change locks is a decision, and the first question is whether you need new hardware or only new keys. If the old locks are in good shape, rekeying gets the same result. If they're worn, broken or builder-grade and you want better security, a swap is the better answer. After a break-in, a split jamb, a bent bolt or a damaged cylinder means the lock has to change anyway. Tenants in Covina have particular rights. California Civil Code §1941.3 requires landlords to provide working deadbolts on main swinging entry doors and security for windows that open. Sections 1941.5 and 1941.6 of the same code 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. Keep the order or report handy: inside the city limits it comes from Covina PD, and in Vincent or Charter Oak it comes from the Sheriff's Department. A new lock set comes with its own keys, and you can buy keyed-alike sets so every door opens with one. We remove the old hardware, check the strike and screws, and test the new lock before we leave. For rentals, we verify the lease or authorization first.
How this works in Covina
For renters and landlords in Covina, a lock change sits inside a few California rules worth knowing. Civil Code 1941.3 requires the landlord to install and maintain an operable deadbolt on each main swinging entry door, and a newly installed bolt must extend at least 13/16 inch beyond the door edge when locked. Windows designed to open need working locks, with some exceptions. The tenant's job is to report a lock that stops working. Most leases also say a tenant can't change or add locks without consent, and Civil Code 1954 gives the landlord a right to enter with proper notice, which is why landlords expect a key. Civil Code 1941.5 and 1941.6 add separate rules for certain situations involving a protective order or similar documentation: the landlord must change the locks within 24 hours of the tenant's written request. And a landlord may never change locks to force a tenant out; California treats that as an illegal lockout. We follow these rules on every rental job.
How we can help in Covina
- 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 Covina. 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.
- New lockset installation on existing door prep. When hardware is worn, we change locks by installing new knobs, levers or deadbolts in the holes already cut in your door. Standard prep in Covina homes is a 2-1/8 inch cross bore with a 2-3/8 or 2-3/4 inch backset, which most current residential locks accept. We confirm the measurements before recommending a model.
- Restricted keyways and high-security cylinders. If you change locks because keys keep getting copied, a restricted keyway addresses the cause. Patented systems from Medeco, Mul-T-Lock and ASSA Abloy use blanks that hardware stores can't cut, and duplicates require the owner's card or signature. We can fit these cylinders into many existing deadbolts and handlesets.
- Keying every door alike. People forget the secondary locks: the door from the garage into the house, a detached workshop, a security screen door, a pool gate. If those stay on old keys, the job is only half done. We walk the Covina property with you, list every keyed cylinder, and bring them under one new key unless you want separate access.
- Urgent safety lock changes. California gives protected tenants specific lock rights. Under Civil Code 1941.5 and 1941.6, the landlord must change the locks within 24 hours of the tenant's written request in certain situations involving a protective order or similar documentation. If the landlord doesn't, the tenant may have the locks changed and must then give the landlord a key. We can work for either side.
Local factors in Covina
Inland heat is hard on locks. Doors expand, strikes misalign, and dark finishes on sun-facing doors fade or peel. When you change locks in Covina, choose finishes that tolerate direct sun and keypad locks rated for outdoor heat, and expect batteries to need replacing more often in summer. We set strikes with enough tolerance that the deadbolt still throws easily on the hottest afternoons.
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 Covina 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.
Long commutes mean long empty hours at home, and a lock change for commuters should account for that. In Covina, 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.
Common situations
Say a family in Vincent comes home from a weekend away to find the front door ajar and the deadbolt's bolt bent. Nothing is missing, but the lock was clearly forced. The sheriff's report is filed, and they call us on Sunday. We'd verify ID and the property, replace the damaged deadbolt with a Grade 1 model, install a heavy strike plate with long screws, and swap the knob to match the key. Whoever has the old keys would be locked out for good.
- 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.
- A typical call: a roommate in a Covina rental moves out after an argument and keeps a key. The remaining tenant contacts the property manager, who agrees to a rekey as long as the office receives a copy. We'd check the lease and ID, re-pin the entry deadbolt and handle, cut keys for each remaining tenant plus one for the manager, and note who received them.
- For instance, a newer Covina home sells with a Wi-Fi deadbolt that the sellers still control from their phones. They're cooperative but slow to remove themselves from the app. We'd factory-reset the lock, delete stored codes, enroll the new owner as administrator, connect it to the new owner's network, and rekey the override cylinder, because the key the sellers kept would otherwise still open the door.
How the visit works
- Tell us the reason and count the doors. The reason behind a lock change sets its priority. A safety concern or a stolen keyring gets the earliest slot we can honestly offer within our hours; a planned move-in can be booked around your schedule. Either way, we give an arrival estimate based on where our technician is when you call.
- Verify residence or ownership. Executors, trustees and property managers can authorize a lock change too, with the right paperwork: letters testamentary, a trust document, or a management agreement or work order. If the papers are somewhere you can't reach, we'll talk through what else might work before anyone touches a lock.
- 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. Each new key gets tried in each lock it should open, with the door open and again with it closed, because a strike that binds only shows up when the door is shut. We check the inside thumbturn, the deadbolt's full throw, and that the latch catches on its own.
- Hand over keys and records. Before we leave, we note the brand and keyway of your new cylinders so future copies come out right, and we explain which keys can be copied anywhere and which need authorization. For tenants and landlords in Covina, the dated invoice documents exactly when the change happened.
How we quote the job
- Hardware grade, brand and finish. If you replace locks, the hardware you choose matters as much as the labor. Grade 3 builder locks are inexpensive; Grade 1 deadbolts and quality handlesets cost more but stand up better to heat, daily use and force. Finish matters too, especially on a sun-facing door. We'll show you choices at several price points.
- Keys, key control and smart features. Standard keys are inexpensive to cut, so a normal key count barely moves the total. Patented and restricted keys cost more per key and per cylinder, and copies come through authorized channels. If you need many keys for a large family, a rental or staff, mention it so the quote reflects it.
- Timing, travel and urgency. Urgency costs less than people expect when the job is a straightforward rekey, since the hardware is already on the door. It adds cost when a special lock has to be sourced quickly. In that case we secure the doors with what we carry and finish with the ordered hardware on a second visit.
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 Covina.
Practical tips before you call
- Avoid double-cylinder deadbolts on doors you might need to escape through during a fire. They require a key on both sides, and in a smoky hallway nobody finds a key. If glass beside the door worries you, consider laminated security film or a sturdier door instead. We can talk through options that keep getting out simple.
- 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.
- Planning a lock change for a rental or vacation home in Covina? Consider a keypad deadbolt with a keyed backup on the main entry. Guests and cleaners each get their own code, and removing one takes seconds. Keep the mechanical keys few and accounted for, because the keypad is only as secure as its override cylinder.
- If you rent in Covina, 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.
What not to do
- Spraying oily lubricant into the keyway. It frees a sticky lock briefly, then attracts dust and turns into paste around the pins, especially in windy inland neighborhoods. If you've already done it, a solvent flush and dry lubricant may save the cylinder; otherwise a rekey with clean pins solves the problem.
- Buying hardware before measuring. A lock with the wrong backset, a latch with the wrong faceplate shape, or a deadbolt that's too short for a thick door leads to returns, extra drilling or a lock that never closes properly. Measure first, or have a locksmith measure while assessing the door.
- 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.

Frequently asked questions
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.
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.
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.
Does changing my locks stop old garage door remotes?
No. Garage openers are a separate system. After you change locks, clear the opener's memory using the learn button on the motor unit, reprogram your own remotes and car buttons, and change the exterior keypad code. If your garage connects to the house, key the door between them with the rest, because anyone with a working old remote can reach it.
My ex has a key. Can I change the locks?
If you're the only owner, or the only tenant on the lease with landlord consent, yes, after verification. If you both own the home or are both on the lease, a lock change doesn't erase the other person's legal rights, and excluding them can create legal trouble. A protective order changes that picture. Talk with an attorney or legal aid if you're unsure, then call us.
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.
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.
