Claremont, Los Angeles County
Lock and Key Service in Claremont
Short answer: If a copied key won't turn or a lock fights every key, the lock and the key usually need attention together. A lock and key service in Claremont can cut fresh keys to the original code instead of copying a worn copy, clean or re-pin the cylinder, and confirm every key works in every lock before leaving.

Julian's Locksmith provides lock and key service for homes, rentals, small businesses and vehicles in Claremont. That covers key cutting and duplication, rekeying, lock repair, new deadbolts and locksets, small locks, broken key extraction and spare car keys. We're a mobile company licensed by the state as LCO7891, insured and bonded, working from San Bernardino every day from 6:30 a.m. to 11:30 p.m. Call (951) 903-3193, describe your locks and keys, and we'll quote before any work starts. If you're not sure what a lock is called, a photo texted to us is enough.
What to know first in Claremont
Inland Southern California is hard on locks. Fine dust works into keyways, summer heat expands metal and dries out old grease, and Santa Ana winds push grit into gate locks and padlocks that live outdoors. Sprinkler overspray adds hard-water deposits to side-gate hardware. A lock and key service in Claremont deals with all of it as routine work. Often a sticky lock just needs cleaning and a dry lubricant made for locks, such as a PTFE spray or graphite, rather than household oil, which gums up and traps dust. A deadbolt that only locks when you push or lift the door usually isn't a bad lock at all; the door has sagged or the frame has shifted, and adjusting the strike plate fixes it. When a cylinder is worn past cleaning, re-pinning or replacing just the cylinder often beats buying a new lockset. We'll tell you honestly whether repair, rekeying or replacement makes sense for each lock, and we put that recommendation in writing with the quote.
Work included on a typical visit
- Repairing sticky, loose and binding locks. Locks rarely fail all at once. They stick, then grind, then refuse. We clean dirty cylinders, apply a dry lubricant made for locks, and replace worn springs or pins. Catching it at the sticky stage in Claremont usually saves the lock and avoids a key snapping off inside.
- Replacing worn-out locks and deadbolts. Smart locks, keypads and mortise locks are replacements too. We can install a Schlage Encode, Yale Assure or Kwikset Halo, or a matching keypad deadbolt, and key its backup cylinder to the rest of your house. One mechanical key still works everywhere, even if a battery dies.
- Padlocks and gate locks. Side gates and yard gates take a beating from sun, dust and sprinkler spray. We service gate latches, replace corroded keyed latches, and install weather-resistant hardware that holds up outdoors. Where the gate lock shares a keyway with the house, we key it alike, so one key opens everything.
- Spare car keys and fobs. A full lock and key service covers vehicles too. We cut and program spare transponder keys, flip keys and many proximity fobs at your home or work in Claremont. A spare made while you still have a working key is far simpler and cheaper than starting over after the last key is lost.
- Broken keys pulled from locks. A key that breaks in a deadbolt with the bolt extended can leave you locked out. We extract the fragment, turn the cylinder with a tool to retract the bolt, and then decide with you whether to cut a new key, rekey or replace a lock that's clearly worn.
How Claremont shapes the job
Busy family homes in Claremont lose keys constantly: to backpacks, sports bags and the couch. Keying every exterior door alike means one key for everyone, and a keypad deadbolt on the main entry means kids don't need a key at all. We'll cut and color-code copies for each person, and add a spare car key while we're there if you need one.
Inland summers in Claremont are tough on locks and keys. Heat dries out factory grease, expands metal so bolts rub their strikes, and drains batteries in keypad and smart locks. If a lock gets stiff every afternoon, an adjustment usually fixes it. We also suggest keeping a mechanical key cut for every smart lock, because a dead battery on a hot day is a common lockout.
Commuters in Claremont leave early and get home late, so lock and key errands rarely fit into the day. That's where a mobile visit helps. We start at 6:30 a.m. every day and work until 11:30 p.m., so a rekey, new copies or a spare car key can happen before you leave or after you're back, with your car sitting in the driveway.
Example situations
- Picture someone in Claremont whose house key snaps off in the deadbolt on a weekday morning, with half the key still inside and the door locked. We'd extract the broken piece, turn the cylinder to retract the bolt, check the pins for damage, and cut new keys to code. A worn key snapping usually means the others are close too, so we'd replace them all.
- A typical RV call: a travel trailer stored near Claremont has compartment locks that all open with the common CH751 key, which plenty of other owners carry. We'd replace the compartment cylinders with uniquely keyed ones, key them alike so one key runs the whole trailer, and check the entry door lock and deadbolt while we're there.
- Say a landlord is turning over a rental near Memorial Park. Beyond rekeying the front and back doors, the unit needs a mailbox key, a laundry room key and a side gate padlock. We'd rekey the doors, replace the mailbox lock, swap the padlock for one keyed alike, and hand over labeled sets for the incoming tenant and the landlord.
- Consider a 1940s house in Claremont with its original mortise lock on the front door and a key that finally cracked. We'd remove the cylinder, check whether the mortise body and its parts are still sound, rekey or replace the cylinder, and cut new keys. If parts for that lock are scarce, we'd explain a retrofit that keeps the look of the door.
How the visit works
- Send us your whole list. Call (951) 903-3193 and tell us everything on your list, not just the most urgent item. Copies, sticky locks, a mailbox key, a padlock, a spare car key: knowing it all up front lets us quote the visit and load the right parts. A note on your phone beforehand helps.
- Brands, codes and photos. A quick phone photo of each lock and your keys helps us prepare. From a clear picture we can usually tell the keyway, the lock grade and whether rekeying or replacement makes more sense before we arrive in Claremont, which keeps the quote accurate and the visit short.
- One quote for the visit. If part of your list needs ordered parts or dealer programming, we split the quote clearly. You can approve the on-the-spot work now and schedule the rest, and the later visit carries no surprise charges beyond what we already discussed with you.
- Arrival, ID and a walk-through. We walk the property with you in Claremont, try each existing key in each lock, and note what sticks, what wobbles and what's missing. That quick walk-through often turns up a gate lock, a garage entry door or a shed padlock you'd forgotten to mention.
- Cutting, pinning and repairs on site. Most of the work happens right at your door or in the van: cylinders pulled and re-pinned, keys cut by code, strikes adjusted, worn parts replaced and new locks installed. You can watch and ask questions, or carry on with your day while we work.
- Every key tested in every lock. We hand over the keys counted and labeled if you'd like, and an itemized invoice listing each task and part with our license number, LCO7891. Old keys that no longer work can go back to you or into our disposal bag.
How we quote the job
- Key types and blanks. Code cutting a key when no original exists takes more time than duplicating one you hand us. Decoding a lock or reading a code from paperwork is still far less than replacing the lock. We quote each key type separately, so you can see the difference.
- Lock condition and hardware type. Commercial hardware such as mortise locks, interchangeable cores and Adams Rite deadlatches takes longer to service than a residential knob. Older or discontinued locks may need parts hunted down or a retrofit kit. We'll identify exactly what you have, ideally from a photo, before quoting.
- Drive from San Bernardino. We work from a base near Cal State San Bernardino and come to you, so mileage is part of the quote. A short trip costs less than one across two counties. We include it in the total instead of adding a separate fee at the door.
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
- Replacing a perfectly good lock just to get new keys. If the hardware is solid and you like it, rekeying achieves the same result for less. Save the replacement budget for locks that are worn, cheap, damaged or due for a security upgrade.
- Keeping a spare under the mat, above the door frame or in a fake rock. Those are the first places anyone checks, and a found key leaves no sign of entry. Give a spare to someone you trust, or use a quality lockbox or a keypad deadbolt instead.
- Ignoring a wobbly deadbolt or loose knob. Loose hardware only gets worse, and a lock that shifts in the door is easier to force. A few minutes of tightening, or a replacement spindle or screw, prevents a failure at a bad moment, like when you're rushing out.
Advice before you book
- Bundle small lock and key jobs into one visit. A mailbox key, a padlock, a loose knob and new house copies add up to a short list if they're handled together. Keep a running note on your phone so the list is ready when you call.
- Use colored key caps or a dot of nail polish to tell keys apart instead of writing your address on them. A key tagged with an address is an invitation if it's lost. A color code keeps the information in your head, not on the ring.
- Write down the key number stamped on new padlocks and file cabinet locks, and store it with your home records or in a note on your phone. With that number, a replacement key can often be cut by code without opening, drilling or replacing the lock.
- Watch your keys for warning signs: rounded peaks, a visible bend or a crack near the shoulder. A worn key is the one most likely to snap off in the lock. Replacing it with a code-cut key costs far less than an extraction later.
Service in Claremont
Claremont is about 30 miles from our San Bernardino base, roughly 34 minutes in light traffic via University Parkway to I-215 South. When you call, you get an arrival estimate based on where the technician is and the traffic at that moment.

Here are our real hours: 6:30 a.m. to 11:30 p.m., every day of the week, weekends included. We aren't a 24/7 locksmith and won't pretend to be. If you're locked out while we're closed, your auto club or your property manager's emergency line may get you in sooner, and we're glad to book you for the moment we reopen.
Safes get the same scrutiny. Before drilling or manipulating one, we need reason to believe it's yours: a purchase record, the fact that it sits in your home or business, or estate paperwork if you inherited it. A safe exists to keep people out, so proof of ownership isn't optional.
Locked out in Claremont?
Call (951) 903-3193 with the address and what's locked. You'll get an arrival estimate and a quote before anyone heads out, and when we arrive we'll ask for ID that ties you to the property. If a child or pet is shut inside a hot car or building, call 911 first.
Frequently asked questions
What if a key breaks off inside the lock?
Leave it alone and call us. Pushing the broken piece deeper or trying glue makes extraction harder. We'll pull the fragment with extraction tools, check the cylinder for damage, and cut a new key from the pieces or the code. If the key broke because the lock was stiff, we'll fix that too, so it doesn't happen again.
Can you copy a key stamped Do Not Duplicate?
The stamp alone doesn't stop copying, because the blank underneath is common. We still take it seriously. For a business or rental key, we'll want the owner's or manager's permission first. For a key you own outright, we'll ask a few questions. If you truly need copy control, a restricted keyway that requires authorization is the real solution.
What does a lock and key service include?
Everything that keeps your locks and keys working together: key cutting and copying, cutting keys by code when there's no original, rekeying, repairing sticky or loose locks, replacing deadbolts and knobs, small locks such as mailboxes, cabinets and padlocks, broken key extraction and spare car keys. Julian's Locksmith handles all of it as a mobile service in Claremont.
Can you replace a lost mailbox key?
Yes, for most residential mailboxes. We'll ask for ID or a lease showing your address, then either cut a key from the lock code or replace the lock with a new cylinder and keys. On cluster mailboxes, the compartment lock is often the owner's or HOA's responsibility, so check that before we come out.
Why is my deadbolt so hard to turn?
Most of the time, the bolt is rubbing the strike plate because the door has sagged or the frame has shifted. Test it with the door open: if it turns easily, it's an alignment problem, and adjusting the strike or tightening the hinges fixes it. If it's stiff even with the door open, the cylinder needs cleaning or repair.
Do you make spare car keys with chips?
Yes, for many makes and models. We cut the blade and program or clone the transponder chip so the car starts, and we handle many remote-head keys and proximity fobs too. Some vehicles need dealer-only programming, and we'll say so on the phone. We verify ownership with ID and registration before making any car key in Claremont.
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.
