One Key for Every Door: Same Key for All House Locks in Arcadia

What to expect in Arcadia

The question that decides how simple this will be is which keyways you have. Kwikset KW1 and Schlage SC1 are the two you'll find on most Arcadia homes, and they don't accept each other's keys. Kwikset's SmartKey cylinders use the KW1 keyway, so a SmartKey deadbolt can share a key with an older pin-tumbler Kwikset knob, and Baldwin's Prestige and Reserve lines run on SmartKey too. Many store-brand locks are built to take a KW1 or SC1 key, which often lets them join the plan. Mixing Schlage's five-pin SC1 and six-pin SC4 cylinders is normally workable; we pin them so one key runs both. Where brands collide, there are three paths. We can replace the odd lock with one in your main keyway, fit a matching cylinder if the hardware accepts one (mortise and rim locks usually do), or occasionally convert the whole house to the other brand if that side has fewer locks. High-security cylinders from makers such as Medeco or Mul-T-Lock are a separate conversation, since their patented keys can't be cut from standard blanks. We lay out each option with its cost before any work starts.

What we can do on-site

• Bringing odd-brand locks into line. A Schlage deadbolt on a house full of Kwikset locks can't share their key as it is. We either swap it for a lock in your main keyway, fit a compatible cylinder where the hardware allows, or, if the numbers favor it, move the whole house to the other brand. You'll see each option priced before we start.
• 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.
• 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. Once the house runs on one key, a new deadbolt or replacement knob doesn't have to break the system. Buy hardware in the same brand and keyway, or let us supply it, and we key the new cylinder to your existing combination during installation. You won't need a second key, and the pattern stays intact.
• Fixing worn or sticky locks along the way. There's no point matching a lock that fights its key. While each cylinder is apart, we check pins for wear, springs for fatigue and the plug for grit. Worn parts get replaced, the cylinder gets a dry lubricant, and a lock that was sticky before turns cleanly with the new key.

How Arcadia shapes the job

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.

Older homes in Arcadia 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.

Townhomes and condos often mix your own locks with association-controlled ones: a unit door you're responsible for, a garage on a shared drive, and a common-area gate that runs on the HOA's key. Your unit door, patio gate and garage entry can usually share one key. Shared gates, pool doors and mailbox locks stay on separate systems that the association manages.

Example situations

• For example, a house off Second 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.
• A typical call: the front door has a Schlage deadbolt and handleset, the back door a Kwikset knob and deadbolt left from an old repair, and the garage entry a Schlage knob. The owner wants one key. Since three of the five cylinders are already Schlage, we'd rekey those, replace the two Kwikset pieces with Schlage hardware, and set everything to one fresh combination.
• Say an older Spanish-style home near Santa Anita Park 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, 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.

From your call to the finished job

1. Send photos and a count of your locks. Tell us what's on the ring now: how many different keys, which doors they open, and whether any lock has no key at all. That last detail matters, since a lock without a working key needs picking or decoding before it can be rekeyed with the others.
2. 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.
3. 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.
4. 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.
5. Rekey and reinstall each cylinder. Door by door, we remove the cylinder, slide the plug out with a follower, replace the key pins to fit the new key and add fresh springs where needed. Each cylinder is tested on the bench before it goes back in, then again once it's mounted on the door.
6. Test every door and hand over the keys. Before we leave, you try the key yourself at every door. If anything feels stiff, we fix it then and there. We note the brand and keyway on your invoice so future locks can be bought to match, and we take the old pins away with us.

How we quote the job

• Whether all locks share a keyway. A house fitted entirely with one brand is the least expensive to put on one key, since everything is a rekey. Every lock in a different keyway needs a replacement cylinder or replacement hardware, and that changes the total more than anything else. We'll show you how the numbers compare for each option.
• Number of key copies. With one key for everything, it's tempting to hand copies to everyone who might ever need one. Every extra copy adds a little to the bill and a little to your exposure. We'll cut what you ask for, but most families are better served by fewer keys and a clear record of who holds them.
• Timing, travel and combined work. A planned one-key rekey costs less than an urgent one because we can schedule it efficiently and bring exactly the right parts. If you're moving in, booking the day you get keys works well. We're open every day from 6:30 a.m. to 11:30 p.m.

Common errors that cost time and money

• 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.
• Buying a new lock combo pack and assuming it'll match the locks already on the house. Factory packs are keyed alike only within the box, or to other boxes printed with the same keying code. Unless the new lock gets rekeyed to your existing combination, you've just added another key to the ring instead of removing one.
• 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.

Practical tips before you call

• Don't forget the door between the garage and the house. People rekey the front door and overlook the one entry that a stolen garage remote can lead straight to. If the garage entry has only a knob, ask about adding a deadbolt keyed to the same key while we're there.
• 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.
• 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.
• Ask for the new key to be cut by code, and keep the invoice that records the keyway. Future copies made from the code will match perfectly, while copies made from worn copies gradually lose accuracy and can leave one door that only opens with a wiggle.
