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

What to expect in Cerritos

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 Cerritos 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.

Work included on a typical visit

• Rekeying same-brand locks to one key. Same-brand houses are the easy case. A home fitted throughout with Kwikset, or throughout with Schlage, can usually be brought to one key using only pins, springs and a code-cut key. No hardware gets replaced, the trim stays as it is, and the visit mostly consists of disassembly, re-pinning and careful testing at each door.
• Gates, sheds and padlocks. Not everyone wants the yard on the house key. If a gardener, pool tech or neighbor needs gate access only, keep the gate on its own key or fit a keypad gate lock, and leave the house on your main key. We set it up whichever way fits how your property actually gets used day to day.
• 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. A deadbolt that's hard to turn often isn't a cylinder problem at all. A sagging door or misplaced strike makes the bolt drag, and people blame the key. We adjust the strike or hinges so the bolt throws freely, because one hard-turning door will eventually bend the key everyone in the house depends on.
• 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.

What's different about Cerritos

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.

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 Cerritos, 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.

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-91 or as you get home.

Example situations

• Picture a side gate padlock that has rusted stiff after a few summers of sprinkler overspray. The owner wants the gate on the house key. That padlock can't be re-pinned, so we'd suggest a rekeyable padlock that takes the same keyway as the house, set it to match, and choose one with a weather cover, while rekeying the house doors during the same visit.
• 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.
• 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.
• For example, a house off Bloomfield 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.

How the visit works

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. Lay your current keys out on a table and try each door, noting which key opens what. Put a strip of tape on each one. That short exercise saves time during the visit and tells us right away whether a lock is already struggling.
3. Verify ownership and confirm the plan. This is the moment to raise anything you're unsure about: whether the gate should be included, how many keys to cut, or whether a tired knob should be replaced. We'd rather settle those questions now than halfway through, and the quote reflects the final list.
4. Pick the new key combination. We generate a fresh combination for your house rather than reusing any old key, so nobody who held a previous copy can open anything. The cuts are checked against the maker's maximum adjacent cut specification, which keeps neighboring depths close enough for the key to slide in and out smoothly.
5. 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.
6. 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

• 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.
• Missing keys and stuck locks. If a key broke off in a lock, or a cylinder was damaged in a forced-entry attempt, that lock needs extraction or repair before it can match the rest. We quote that work separately, so you can see what the one-key plan costs and what the repair adds.
• 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.

What to do before we arrive

• Treat a lost house key as a whole-house event once everything shares it. If that key disappears somewhere it could be linked to your address, rekey every lock it opened, not just the front door. That's the trade-off for convenience, and it's the same straightforward job as before.
• Keep your spare with a trusted neighbor or in a lockbox you control, not under a mat, in a fake rock or on top of the door frame. With a single key running the whole house, a hidden spare that a stranger finds is a key to everything you own.
• 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.
• If you rent, get the landlord's written permission before any rekey, and plan to give them a copy of the new key if your lease requires it. Many landlords are happy to approve one-key keying, especially when the tenant covers the cost and the work is done by a licensed locksmith.

What not to do

• 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.
• 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.
• 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.
