Sierra Madre, Los Angeles County
Same Key for All House Locks in Sierra Madre
Short answer: Yes. In most Sierra Madre 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.

In a house with kids, a partner on a different schedule and maybe a grandparent who visits, keys get borrowed, swapped and lost. When every door answers to one key, nobody has to remember which key opens the side door, a teenager can't grab the wrong one on the way out, and anyone arriving home in a hurry gets inside on the first try. Julian's Locksmith sets Sierra Madre homes up with the same key for all house locks by rekeying the cylinders you already own. You decide how many copies to cut and who gets them. We'll also point out any lock that's worn enough to fight a key, because one stubborn door spoils the whole plan.
What to expect in Sierra Madre
A typical Sierra Madre 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. Many tract homes in Sierra Madre came from the builder with one brand on every door, sometimes already keyed alike. Even then we rekey to a new combination, since builder keys passed through crews, model-home staff and previous owners. Your locks keep their finish and function; only the pin stacks inside change, along with who can open them.
- Smart locks and keypads on the house key. Some smart locks ship with cylinders in a proprietary keyway that no standard key blank fits, and key-free models have no cylinder at all. We'll tell you which category yours falls into. For a proprietary cylinder, the choice is living with one extra backup key stored safely or switching to a model whose cylinder can match.
- Security screen door deadbolts. Steel security screen doors are everywhere in Southern California, and many carry their own deadbolt with a separate key. When that cylinder is a standard KW1 or SC1 type, we rekey it to match your entry door so one key opens both layers. If it's an off-brand or proprietary cylinder, we check whether a matching replacement fits.
- Garage entry and side door locks. The door from the garage into the house is one burglars like, because a stolen remote or a forced side door gets them into the garage unseen. That lock deserves the same attention as the front door. We rekey it, along with any garage side door, to your one key and check that both deadbolts throw fully.
- Two-key and master key options. A two-key plan is simpler than master keying and suits many households: the main house on one key, outbuildings or the yard on a second. Workers get the second key only. We'll help you decide what goes where, so the setup reflects how people really move around your property rather than a tidy diagram.
Local factors in Sierra Madre
Foothill homes often have more exterior doors than flatland houses: walkout lower levels, side doors onto decks and gates on steep paths. In wildfire country there's another reason for one key. When an evacuation order comes and you're grabbing what you can, a single key that locks every door is one less thing to sort out on the way down the hill.
Larger homes can have a dozen or more keyed points across guest houses, pool cabanas, wine rooms and service entrances. One key for everything is rarely the best design there. A residential master key plan, or several keyed-alike zones under one owner's key, lets staff and guests reach only what they need. High-security cylinders with patented keys can be keyed alike across the whole estate too.
Older homes in Sierra Madre 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.
Example situations
- A typical situation: a family with a casita rented to a graduate student wants one key for the main house but needs the casita kept separate. We'd key the main house doors, garage entry and side gate alike, set the casita on its own key, and suggest the owners store their copy of the casita key away from the everyday ring.
- For example, a remodel leaves a Sierra Madre home with a handsome new front door and a designer handleset still keyed to its factory combination, while the rest of the house runs on one Kwikset key. If the handleset accepts a KW1 cylinder, we'd swap or re-pin it to match; if it uses its own keyway, we'd check whether a compatible cylinder is available before suggesting anything else.
- Say an older Spanish-style home near Sierra Madre Playhouse still has its original mortise lock on the front door, plus a newer deadbolt above it. The owner wants both on one key along with the back door. If the mortise body is sound and accepts a standard threaded mortise cylinder, we'd fit one in the house keyway and key it to match the deadbolt and back door.
- For example, a house off Mountain Trail Avenue 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.
From your call to the finished job
- Send photos and a count of your locks. Walk the house before you call and count every keyed lock you use, including the garage entry, side door, security screen door and gate. A knob and a deadbolt on the same door count separately. A realistic count lets us give an honest estimate and plan enough time on-site.
- Gather a working key for each lock. Before we arrive, find a key that opens each lock, even if it's a worn copy. With a working key, the plug comes out in moments. Without one, we pick or otherwise open the cylinder first, which adds time but is usually still cheaper than replacing the lock.
- Verify ownership and confirm the plan. On arrival we verify that you own or live in the home, usually with ID and something showing the address. Then we walk the doors together, mark each lock as rekey, replace or leave out, and confirm the price before any cylinder comes off a door.
- 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. 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.
Pricing factors
- 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.
- Timing, travel and combined work. Combining jobs on one visit saves a second service call. If you also need a new deadbolt installed, a smart lock set up or a broken knob replaced, mention it when booking. We can key everything to the same new combination during that single trip to Sierra Madre.

Practical tips before you call
- 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.
- Bundle the one-key rekey with any other lock work you've been putting off. Replacing a wobbly knob, adding a deadbolt or installing a smart lock during the same visit means everything gets keyed to the new combination at once, instead of paying for a second trip later.
- Use a dry lubricant made for locks, such as a graphite or PTFE product, once or twice a year. Oil-based sprays attract dust and gum up pins over time, especially in hot, dusty inland summers, and a sticky cylinder is the first thing that makes a one-key setup feel unreliable.
Mistakes to avoid
- 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.
- 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.
- Spraying oil into stiff cylinders right before the rekey. Oily residue holds dust and grit, which makes pins sluggish and can hide wear we'd otherwise spot. If a lock is sticking, leave it alone and mention it; we'll clean it properly during the visit.
Reaching Sierra Madre

Frequently asked questions
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.
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.
Can Kwikset and Schlage locks use the same key?
Not as they come. Kwikset KW1 and Schlage SC1 keys have different profiles, so neither fits the other's keyway. To get one key, the odd locks need replacing or, on hardware that accepts interchangeable cylinders, a matching cylinder. We usually suggest converting whichever brand has fewer locks, but we'll price both directions if the numbers are close.
Can the garage door be on the same key as the house?
The door between the garage and the house, plus any garage side door, can almost always be keyed to match. The T-handle lock on an overhead garage door is usually a different type of lock with its own key, and most people with an opener never use it. We'll point out which garage locks can join and which can't.
What affects the cost of getting one key for all doors?
The main factors are the number of cylinders, whether they share a keyway, how many need replacement hardware, whether you have working keys for each, and how many copies you want. Smart locks and high-security cylinders add labor. Julian's Locksmith quotes the full job before starting, so you know the price before any lock comes off a door.
How far is Sierra Madre from your base?
Sierra Madre is about 53 miles from our San Bernardino base, roughly 55 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.
