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

What to expect in Downey

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 Downey 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

• Smart locks and keypads on the house key. Keypad and app locks still have a key cylinder for dead batteries, and that cylinder can usually share your house key. Kwikset's Halo and SmartCode models use SmartKey on the KW1 keyway; Schlage's Encode and Connect models take a Schlage C cylinder. We re-pin or reset that backup cylinder so the emergency key matches everything else.
• 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.
• 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. Your new keys are cut by code on a machine in the van, not traced from an old worn key, so every copy matches the pinning exactly. We test each one in every lock before handing it over, turning the deadbolt with the door closed against the strike, where a marginal key tends to show itself.
• 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.

How Downey shapes the job

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 Old River School Road or as you get home.

Apartment renters can rarely change locks without permission, and many complexes rekey units themselves between tenants. If your Downey apartment has a deadbolt and knob on different keys, ask management to key them alike at the next rekey. If they approve a private locksmith, get it in writing and give the office a copy of the new key, since leases usually require one.

Older homes in Downey 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

• 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 house off Imperial Highway 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 an older Spanish-style home near Wilderness 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.
• 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.

How the visit works

1. 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.
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. 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.
6. 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.

Pricing factors

• Whether all locks share a keyway. Mixed keyways cost more because some locks can't simply be re-pinned. Usually it's cheaper to convert the few odd locks to the majority brand; occasionally converting the majority makes sense, for example if you prefer the other brand's grade or style. We price both directions when it's close.
• 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.
• Missing keys and stuck locks. Seized or badly worn cylinders can turn a quick rekey into a repair. Sometimes cleaning and new pins fix the problem; sometimes the cylinder is beyond rebuilding. We'll tell you which situation you're in and get your approval before doing more than the agreed work.

Advice before you book

• 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.
• 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.
• 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.
• 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.

Common errors that cost time and money

• 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.
• 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.
• 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.

Getting to Downey

Downey is about 59 miles from our San Bernardino base, roughly 66 minutes in light traffic via I-215 South to I-10 West through Rialto, Fontana, Ontario, Pomona and West Covina. When you call, you get an arrival estimate based on where the technician is and the traffic at that moment.

If you're close to Brookshire Avenue, tell us which exit or cross street you're nearest. It trims the last mile and keeps the van from circling a block that looks right on the map but isn't.
