Same Key for All House Locks in Claremont
Short answer: The keyway decides whether you can get the same key for all house locks. Kwikset and Schlage keys have different profiles, so a home with both brands needs the odd ones replaced or fitted with a matching cylinder before one key runs everything. Locks of a single brand simply get rekeyed. Julian's Locksmith sorts your Claremont locks on-site and quotes the cheapest route to one key.

Before you ask for one key across the whole house, think about who should be able to open what. Maybe the gardener needs the side gate but not the back door, or a relative living in the casita should keep a separate key. Julian's Locksmith helps Claremont homeowners draw that line, then rekeys everything on the main key to a single new combination. We work every day from 6:30 a.m. to 11:30 p.m., so an early or evening appointment is usually easy to find. Call (951) 903-3193 and we'll talk through the plan before we arrive.
How this works in Claremont
Every pin tumbler lock in your house has a plug that turns only when the pins inside it line up at the shear line. Each key's cuts lift a stack of key pins and driver pins to exactly that line. To give you the same key for all house locks, a locksmith removes each plug, dumps the old key pins, and loads new ones whose lengths match the cuts on one chosen key. Springs and driver pins usually stay, although we replace tired springs and corroded pins as we go. Five-pin residential cylinders such as Kwikset KW1 and Schlage SC1 take only a few minutes each once the lock is off the door; handlesets, mortise cylinders and smart deadbolts take longer because there's more to disassemble. The new combination comes from a key we cut by code, not from copying one of your old keys, so wear doesn't carry forward. When every cylinder is back on the door, we test each one with every new copy, from outside and inside, with the door open and then closed against the strike. Your previous keys stop working at all of those doors at once.
What we can do on-site
- Bringing odd-brand locks into line. Older or less common keyways, such as an original Weiser knob or an aging Weslock handleset, sometimes have a matching cylinder available and sometimes don't. We identify the keyway from the key bow or the lock face, tell you whether it can join your main key, and suggest replacement hardware that fits your existing door prep if it can't.
- Gates, sheds and padlocks. Outdoor locks age fast in sun and sprinkler spray, so we look at them before promising they'll match. A corroded gate cylinder may need replacing rather than rekeying. Once it's sound and set to your house key, a light dry lubricant and a padlock with a weather cover keep it turning smoothly through the summer.
- Cutting and testing your new keys. We cut as many copies as you need, usually one per household member plus a sensible spare. Cutting from the code keeps future copies accurate too. You can choose plain brass, nickel or rubber-grip heads; with one key for everything, most people find a single style easiest to grab without looking.
- Matching new hardware to your existing key. Adding a lock to a door that never had one, such as a deadbolt on the house-to-garage door, is a good time to call. We install it, set the bolt and strike properly with long screws into the framing, and pin the cylinder to the key you already carry, so nothing new goes on your ring.
- Two-key and master key options. If you rent out part of your Claremont property, the tenant's door must not open with your everyday house key. We set the rental unit on its own key and talk you through whether master keying makes sense for owner access, keeping in mind that tenants are entitled to proper notice before a landlord enters.
How Claremont shapes the job
Busy households are where one key pays off most. Kids coming home from school, a parent leaving early, a grandparent watching the children after work: nobody wants to explain which key opens the side door. In the family neighborhoods of Claremont, rekeying the front, back and garage entry doors to one key means every family member carries the same key and gets inside on the first try.
For older adults, fewer keys means fewer fumbles. One key for the whole home, a large easy-grip key head and deadbolts adjusted to turn with light pressure all make daily life simpler. In 55-plus communities around Claremont, we also check whether lever handles would help anyone with arthritis, and suggest that a trusted family member hold a spare key for emergencies.
Older homes in Claremont often carry decades of hardware layers: an original knob, a deadbolt added later, a mortise lock on the front door, maybe a rim night latch nobody uses anymore. Getting one key for that mix starts with sorting what can be rekeyed, what accepts a standard cylinder and what has to be replaced. Original mortise bodies are often worth keeping, because many accept a modern threaded cylinder in your house keyway.
Common situations
- Say a homeowner installed a Schlage Encode on the front door last year and still carries an old Kwikset key for the back door and garage. Because the Encode takes a Schlage cylinder, the fix would be swapping the two Kwikset locks for Schlage hardware and keying them, plus the Encode's backup cylinder, to one key, so a dead battery never sends anyone hunting for a different key.
- For example, a couple closes on a 1970s single-story in South Claremont and receives seven loose keys from the seller. Four turn out to be duplicates, two open nothing, and one works the side door only with a hard jiggle. We'd rekey the front deadbolt, knob, back door, garage entry and side door to one new key, replace the worn side-door cylinder, and cut four copies.
- For example, two people moving in together each arrive with their own key rings. Their rental house has five locks on three different keys. With the landlord's written OK, we'd rekey the matching locks to one key, replace a broken knob with a matching one, and cut copies for both tenants plus one for the landlord if the lease calls for it.
- Say the one key that opened everything was in a backpack stolen from a car at a shopping center, along with mail showing the address. Because every door shares that key, every door is exposed. We'd rekey the whole house to a new combination as soon as the schedule allows, cut fresh copies, and suggest changing the garage opener code as well.
Step by step with Julian's Locksmith
- Send photos and a count of your locks. When you call (951) 903-3193, tell us how many doors and gates you want on the one key, and text photos of each lock face if you can. The brand logo and keyhole shape tell us what pins, blanks and replacement hardware to bring, so we can finish in one visit.
- Gather a working key for each lock. Locks that no one has a key for, like a back door that's always been bolted from inside, aren't a dead end. We can usually open them without damage and rekey them with the rest. Just mention them ahead of time so the schedule allows for the extra work.
- Verify ownership and confirm the plan. Rekeying changes who can get into a house, so we confirm identity and residence first. Renters should have the landlord's permission in hand. Once that's settled, we go door to door, agree on which locks join the one-key plan, and quote the total.
- Pick the new key combination. If some doors use six-pin cylinders and others five, we choose a combination that works across both. Where brand differences remain, the replacement hardware gets keyed to the same new combination before it goes on the door, so everything matches from the first turn.
- Rekey and reinstall each cylinder. As each cylinder comes apart, we look for worn pins, debris and broken springs, and replace what's tired. A lock that comes off the door rough goes back smooth. Any replacement hardware goes in at this step, keyed to match, with strikes adjusted so bolts throw cleanly.
- Test every door and hand over the keys. The last step is a key count. Write down who holds each copy, keep one spare somewhere secure, and never label it with your address. If a key ever goes missing, you'll know how many are out and whether the house needs rekeying again.
What affects the cost
- How many cylinders you're matching. Price follows the number of cylinders more than the number of doors. A front door with a deadbolt and a keyed knob is two cylinders; a security screen door adds a third. A house with five doors may have nine or ten cylinders. We quote per cylinder plus the service call, so you can see how adding the gate changes the total.
- Whether all locks share a keyway. When an odd lock is a mortise handleset or rim lock, fitting a matching cylinder may cost far less than replacing the hardware. For tubular knobs and deadbolts, replacement is usually needed. We check what each lock body accepts before quoting, so you're not paying for new hardware where a cylinder swap will do.
- Smart lock and high-security cylinders. Smart locks take longer to rekey because the interior unit, cables and sometimes the whole lock come off the door before the cylinder can be reached. That extra labor shows up in the quote. Retrofit units mounted over an existing deadbolt add little, since the cylinder underneath is an ordinary one.
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
- Assuming a smart lock removes the need for a matching key. Every keypad with a backup cylinder still has a physical key, and dead batteries are a real possibility. If that cylinder isn't keyed to the house, you'll be hunting for a separate key at the worst possible time.
- Giving copies of the one key to every contractor, cleaner and neighbor who asks. Each copy opens every door you own. Track who has keys, use keypad codes or a separate key for limited access, and collect copies when the work ends.
- Duplicating an old, worn key to make copies for the whole family. Each copy inherits the wear, plus a little more from the copying process. Rekeying to a fresh code-cut key is what gives every door a crisp, reliable match that lasts.
What to do before we arrive
- Consider giving workers a code instead of a key. A keypad deadbolt on a side or garage door lets a cleaner, pet sitter or contractor in without handing over the one key that opens everything, and you can delete the code the day the job ends.
- When you buy a lock in the future, match the brand and keyway of your house key. Better still, call us before installing it and we'll key it to your combination. That keeps the house on one key instead of slowly drifting back to a full ring.
- Before calling, photograph the outside face of every lock you want included. A clear picture of the logo and keyhole tells us the brand and keyway, which decides whether a lock can simply be rekeyed or needs a matching cylinder. Text the photos ahead of the visit so the right parts are already in the van.
- Plan who gets copies before the visit. Write down each person who genuinely needs a key, add one spare, and stop there. With one key opening every door, a short list matters more than it did when each key opened only one lock.

Frequently asked questions
Is keyed alike the same thing as a master key system?
No. Keyed alike means every lock uses the same key. A master key system gives each lock or group its own key, plus one master key that opens all of them. For most homes, keyed alike is simpler and cheaper. Master keying makes sense when someone, like a tenant in a casita, should reach only part of the property.
Do I need to buy new locks to get the same key for all house locks?
Not usually. Rekeying changes the pins inside your existing cylinders, so the hardware stays on the door and only the key changes. You'd need new hardware only for locks in a different keyway that can't take a matching cylinder, or for locks too worn to rebuild. Plenty of homes end up with one key and no new hardware at all.
How long does it take to put a whole house on one key?
It depends on how many cylinders there are and what kind. Standard knobs and deadbolts go quickly once they're off the door; smart locks, handlesets and mortise locks take longer, and any lock without a working key adds time. We'll give you a realistic estimate on the phone once we know your lock count and brands.
Can I keep one door on a different key?
Of course. Some people keep a home office, a casita, a storage room or a workshop on its own key while the rest of the house runs on one. We key the main group alike and set the separate door to a different combination. Just tell us which doors belong in each group before we begin.
Do you need proof that I own or live in the house?
Yes. Before rekeying any home, Julian's Locksmith verifies identity and that you live at or own the property, usually with a photo ID and a document showing the address, such as a utility bill, lease or closing papers. Renters should also have the landlord's permission. It protects you, since a rekey changes who can get into your home.
What if I don't have keys for some of my locks?
That's common, especially in homes that have changed hands several times. A lock without a working key has to be opened first, usually by picking, before it can be rekeyed. It adds some time but is often still cheaper than replacing the lock. Let us know in advance so we can plan the visit around 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.
