Fontana, San Bernardino County
Same Key for All House Locks in Fontana, Matched Door by Door
Short answer: Yes. In most Fontana homes you can have the same key for all house locks without buying new hardware. A locksmith rekeys each cylinder, including the front deadbolt, entry knob, back door and garage entry, to one new combination, provided the locks share a keyway. Julian's Locksmith does the work on-site, cuts fresh keys and tests every door. Call (951) 903-3193.

Most houses don't start with mismatched keys. They drift there. A broken knob gets replaced with whatever was on sale, a new deadbolt goes in after a scare, a garage door gets swapped during a remodel, and ten years later the key ring looks like a janitor's. If that's your Fontana home, getting back to the same key for all house locks means sorting the locks by brand and keyway first. Julian's Locksmith rekeys the ones that can share a key, fits matching cylinders where the hardware allows it, and recommends replacing only the stragglers that have no other route. You get a straight answer and a quote before we start.
What to know first in Fontana
A typical Fontana house has more keyed points than people count at first. The front entry usually carries a deadbolt plus a knob or handleset, and both count. Then come the back or kitchen door, the door between the garage and the house, a garage side door, and sometimes a steel security screen door with its own deadbolt. Outside, there may be a keyed side gate latch, a padlock on the trash enclosure or pool equipment, and a shed. Most of those can share one key if their cylinders are standard and rekeyable. A few usually can't. Sliding patio doors rarely have an exterior cylinder worth matching, the T-handle on an overhead garage door is typically a wafer lock on its own key, and individual mailbox locks belong to a different system altogether. Blister-pack padlocks generally can't be re-pinned, though a rekeyable padlock that takes your house keyway, where one exists for your brand, can replace one. We walk the property with you, mark each lock as in, out or replace, and quote that list before starting, so no surprise second key turns up later.
Work included on a typical visit
- Rekeying same-brand locks to one key. If every lock on your house shares a keyway, this is the whole job. We pull each cylinder, replace the key pins to match a single new key cut by code, and reinstall it. The deadbolt, knob, back door and garage entry all end up on one key, and every old copy floating around stops working the same afternoon.
- Security screen door deadbolts. Security screen doors in Fontana take a beating from afternoon sun, slamming and dust. Before we rekey the lock to your house key, we check that the bolt throws fully into the frame and that the cylinder isn't packed with grit. A gritty cylinder gets cleaned and treated with a dry lubricant so the new key turns easily.
- 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. Before we leave, every new key opens every door it should, and every old key you hand us fails in every lock. We check both directions. It's the only way to be sure no cylinder got missed, which matters with a one-key plan, because a single unmatched door means carrying a second key again.
- Fixing worn or sticky locks along the way. Some locks are past saving. A cylinder with a cracked housing, a knob whose spindle wobbles or a deadbolt that's been forced may cost more to rebuild than to replace. We'll show you what we found and quote a matching replacement, so the house still ends up on one key without a weak link.
Local factors in Fontana
If you leave before dawn and return after dark, fumbling through keys at an unlit door is a daily annoyance. One key for every door lets you lock the back door, the garage entry and the front in seconds. Since our hours start at 6:30 a.m. every day, we can often schedule the rekey before you head out on SR-210 or as you get home.
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 Fontana, 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.
Older homes in Fontana 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
- For example, a house off I-10 has a steel security screen door whose deadbolt uses a different key from the wood door behind it, so every trip inside takes two keys. After confirming the screen door's cylinder is a standard KW1 type, we'd rekey it and the entry deadbolt to the same new key, then adjust the screen door's strike, which had been catching on every close.
- 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.
- Picture a household that hires a pet sitter twice a month and doesn't love handing over the one key that opens everything. We'd key the front, back and garage doors alike for the family, then fit a keypad deadbolt on the garage side door. The sitter gets a code that can be deleted anytime, and the keypad's backup cylinder still matches the family key.
- Picture a grandmother who's started having trouble telling her keys apart, especially at dusk. Her family asks for one key across the house. We'd rekey the front, back and garage doors to match, cut a key with a large rubber head that's easy to grip, and check that each deadbolt turns with light pressure, adjusting a strike that had been forcing her to shove the door.
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. The new key is cut by code first and becomes the pattern for every cylinder. Starting from a fresh, code-cut key avoids inheriting wear from an old copy, which matters because every lock in the house will be pinned to it.
- Rekey and reinstall each cylinder. Knobs, levers, deadbolts and handlesets each come apart differently, and smart locks need their interior units removed and reconnected. We work carefully around finishes, keep track of every small part, and lubricate each cylinder lightly before reassembly.
- Test every door and hand over the keys. With all locks back on, we test each new key in every door from outside, with the door closed so the bolt has to drive into the strike. Your old keys get tried too, and they should fail everywhere. Then you get your copies, and we count them with you.
What affects the cost
- How many cylinders you're matching. Counting locks before you call keeps the quote honest. People often forget the garage side door or a lock on the security screen, then add them during the visit. That's fine, since we'll requote on the spot, but a complete count from the start lets you budget accurately.
- 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.
- Number of key copies. Each key we cut adds a small cost for the blank and cutting time. Most households need one per adult plus a spare. Standard brass blanks keep it economical; colored heads, rubber-grip covers or brand-name blanks cost a little more and are completely optional.
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 Fontana.
Common errors that cost time and money
- Rekeying most of the doors but skipping one, often the garage side door or a back door nobody uses. That forgotten lock still opens with an old key, which defeats the security reason for rekeying and keeps a second key on your ring.
- 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.
- 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.
Practical tips before you call
- If you have a keypad or smart lock, keep its backup key on your main ring rather than in a drawer. Once its cylinder is keyed to match the house, the key you carry every day also solves a dead-battery lockout, which happens more often than people expect.
- 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.
- 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.
- 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.

Frequently asked questions
Can a locksmith make all my house locks work with the same key?
Usually, yes. If your locks share a keyway, a locksmith rekeys each cylinder to the same new combination, so one key opens every door. Locks with a different keyway need a matching cylinder or replacement hardware first. In Fontana, Julian's Locksmith checks each lock on-site and explains which ones can match before we start. Call (951) 903-3193.
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.
I rent my home. Can I get the same key for all house locks?
With your landlord's written permission, yes. California landlords are responsible for working deadbolts and secure entry locks on rentals, and many leases bar tenants from changing locks without approval. Get the OK in writing, give the landlord a copy of the new key if the lease requires one, and keep the receipt. We'll rekey to one key just as we would for an owner.
Will my old keys still work after the rekey?
No. Once each cylinder is re-pinned to the new combination, every previous key stops working in that lock. We test your old keys in every door before we leave to confirm it. That's why getting the same key for all house locks is a smart move after buying a home or losing track of who holds copies.
Can I rekey all my locks to one key myself?
If every lock is Kwikset SmartKey and you have a working key for each, the built-in reset lets you match them yourself. Traditional pin tumbler locks need pins, a rekey kit and practice, and mistakes can leave a cylinder that won't turn. Mixed brands can't be matched by rekeying alone. Most homeowners find a single professional visit simpler.
Can my mailbox use the same key as my house?
Almost never. Individual mailbox locks are small cam locks with their own keyways, and cluster box units fall under postal service rules and the property owner or HOA. Your house key and mailbox key will stay separate. We can replace or rekey a private mailbox lock where that's allowed, but it won't run on the house key.
