Changing Your Locks in Claremont, Explained by a Locksmith
Short answer: To change locks in Claremont, 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.

After a break-in, people want to change locks in Claremont immediately, and that instinct is sound. But the lock usually isn't the part that failed. On a kicked door, the weak point is the jamb around the strike, where soft pine splits or short screws tear loose while the deadbolt itself survives. So a useful lock change after a burglary covers three things: new or rekeyed cylinders in case keys were taken, a reinforced strike anchored into the framing, and a look at the side and garage doors the intruder may have tried first. We describe what we find on a dated invoice, which helps with an insurance claim.
Changing locks means swapping the hardware itself, as opposed to rekeying, and it makes sense in specific cases: a lock that is worn out or broken, an outdated style, a wish for a stronger grade, or a finish you want to match across the house. If the locks work and you simply want new keys, rekeying is quicker and cheaper, and we will say so. Who decides? Owners can change what they like. Tenants should read the lease, since many require landlord permission and a copy of the key. California does give tenants firm protections. Civil Code 1941.3 requires working deadbolts on main swinging entry doors and window security in a rental unit, and Civil Code 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. Claremont has plenty of rentals, from student houses to apartments along Harrison Avenue, so these rules come up. For owners, buying a house from a long-time resident is the classic reason to change or rekey. Our visit covers checking the door prep, installing the hardware, supplying keys and testing every lock. We verify identity and ownership or tenancy before starting.
How this works in Claremont
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 Claremont 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.
How we can help in Claremont
- Rekeying your existing locks. Rekeying is pure pin work. Inside a five-pin Schlage or Kwikset cylinder, the bottom pins are cut to lengths that match one key's cuts. We dump those pins, choose new lengths from a fresh bitting, and load them with tweezers and a plug follower so the springs and top pins never escape. Kwikset SmartKey cylinders reset with a tool instead.
- 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.
- 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 Claremont property with you, list every keyed cylinder, and bring them under one new key unless you want separate access.
- Rental turnover lock changes. For owners with several units, rekeyable cylinders and a key log save money over the long run. On compatible hardware, we can set each unit on its own key with an owner key that opens all of them, so each turnover becomes a quick re-pin rather than a hardware purchase.
Local factors in Claremont
Families collect key holders: babysitters, grandparents, carpool neighbors, a teenager's best friend. Every few years it's worth asking who still has one. When we change locks in Claremont family neighborhoods, many parents add a keypad deadbolt so kids come home with a code instead of a key on a shoelace, and a forgotten code costs nothing to replace. The keyed backup still gets rekeyed with the rest of the house.
For older residents, a lock change can double as an accessibility upgrade. Lever handles are easier than knobs for arthritic hands, and a keypad deadbolt with large backlit buttons removes the struggle with a small key. In a Claremont 55-plus community, we also think about caregivers and family: separate codes for each helper make it simple to end access when a caregiver changes.
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 Claremont 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.
Situations this covers
Say a tenant in an apartment near Harrison Avenue gives the property manager a copy of a protective order and asks for new locks. The law gives the landlord 24 hours to act, so the manager calls us. After confirming the manager's authority, we replace the cylinder on the unit's entry door, make sure the new key goes to the tenant and test the bolt. We also check the window latches, since that unit's security matters.
- Say a homeowner carries four keys for one house: Schlage on the front, Kwikset on the garage entry, an older Weiser on the back door and an unmarked padlock on the gate. They want a single key. We'd keep and rekey the Schlage hardware, replace the other two locks with Schlage-keyway hardware, and fit a rekeyable padlock on the gate so it joins the system.
- A typical call: a roommate in a Claremont 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.
- 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.
Step by step with Julian's Locksmith
- 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. Verification isn't a formality. A lock change is exactly what someone attempting an illegal lockout would ask for. So we match photo ID to proof of residence or ownership, confirm a property manager's authorization in writing, and decline work that would shut out someone with a legal right to be there.
- 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.
How we quote the job
- Rekey versus new hardware. The single biggest factor is whether your locks can be rekeyed. A rekey uses pins and labor, while a replacement adds the price of each lockset. Many homes split the difference: rekey the good hardware, replace only what's worn. We quote both options per door so you can see where the money goes.
- Number of doors and cylinders. Every keyed cylinder adds work: the front deadbolt and handle count as two, and a garage entry, back door, side gate and security screen door each add more. Pricing tracks that count. Telling us accurately on the phone avoids surprises when we find a second deadbolt or a forgotten workshop door.
- 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 Claremont.
Common errors that cost time and money
- Hiring from an ad with a suspiciously low lock-change price. Some unlicensed operators quote one figure, drill locks that could have been rekeyed, then charge far more. In California, a locksmith company must hold a BSIS license, so ask for the number and check it at search.dca.ca.gov before any work starts.
- Changing only the front door lock. Burglars and former key holders don't care which door they use, and the garage entry door is often the weakest one in the house. If you change locks, change all of them, or rekey the rest to match, so no old key still works anywhere on the property.
- 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.
Practical tips before you call
- Buying a house in Claremont that has a smart lock? Ask your agent to put the admin handover on the sellers' move-out list. Even so, factory-reset the lock after closing, check the app for shared users and any connected hub, and change the Wi-Fi password the sellers may have left on the router.
- 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.
- Use dry lubricant on exterior locks in dusty inland areas. Graphite or a PTFE-based dry spray keeps pins moving without attracting grit. Oily sprays feel smooth for a week, then collect dust blown in by Santa Ana winds and gum up the cylinder. A puff in the keyway twice a year is plenty for most residential locks.
- Keep one spare key somewhere smarter than a planter, a fake rock or the ledge above the door. A trusted neighbor, a relative who lives nearby, or a code-protected key box whose code you change now and then all beat the obvious spots. Anyone walking a South Claremont street looking for an easy target knows where people hide keys.

Frequently asked questions
How fast must a landlord change locks for a domestic violence victim?
Within 24 hours of the tenant's written request, in certain situations involving a protective order or similar documentation, under Civil Code 1941.5 and 1941.6. Which section applies depends on whether the restrained person lives in the same unit. If the landlord misses the deadline, the tenant may have the locks changed and must give the landlord a key. We treat these as priority calls in Claremont.
What do I need to show before you change locks?
A photo ID plus something that ties you to the address. Owners can show a deed, closing statement, property tax bill or utility bill. Tenants can show a lease and ID, and we may ask about landlord consent. Property managers and executors need authorization paperwork. We verify before every lock change so we never help someone lock out a person with a legal right to the home.
How long does a lock change take?
A straightforward rekey moves quickly, and a typical house is usually finished in one short visit. Replacing hardware takes longer per door, especially when a strike needs relocating or a bore needs enlarging. Smart lock installs add time for pairing and code setup. We'll give you a realistic estimate once we know the door count and what you've chosen.
Should I rekey or change my locks?
Rekey if your locks work smoothly, you like how they look, and the only problem is that someone else might have a key. Replace if a lock is worn, damaged, ungraded, the wrong brand to match your other locks, or you want features such as a keypad or a high-security cylinder. Many Claremont homes get a mix of both, and we quote each door separately.
Can you change the lock on a sliding glass door?
Usually, by replacing the mortise latch and handle with a matching unit, though sliders vary widely by manufacturer and many have no exterior key at all. Because the latch is the weak point, we often add a secondary lock such as a foot lock or a pin through the frames. A bar or dowel in the track remains a cheap, effective backup.
Do smart locks replace the need to change locks?
They reduce it. With a keypad or app-controlled deadbolt, removing someone's access is a code deletion. But nearly every smart lock has a keyed backup cylinder, and retrofit models keep your old one, so mechanical keys still matter. When we install a smart lock in Claremont, we key its cylinder to a key you control and confirm old keys no longer turn it.
How far is Claremont from your base?
Claremont is about 30 miles from our San Bernardino base, roughly 34 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.
