Same Key for All House Locks in Duarte

Short answer: Yes. In most Duarte 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.

Same Key for All House Locks in Duarte, CA — New homeowners receiving keys after a rekey

Count the keys on your ring that belong to your own house. For a lot of people in Duarte it's four or five: one for the front deadbolt, another for the knob below it, a third for the back door, something for the garage entry and a mystery key nobody remembers. Getting the same key for all house locks fixes that in one visit. Julian's Locksmith rekeys your existing cylinders to a single new key, so you stop sorting through brass at the door after dark, and your old keys, wherever they ended up, quit working. If a lock can't be matched, we'll tell you why and what the simplest fix is. Call (951) 903-3193 to set it up.

How this works in Duarte

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 Duarte 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. Retrofit smart locks that mount on the inside of an existing deadbolt, such as August, leave the exterior cylinder untouched, so your house key keeps working there automatically. Level Bolt works similarly inside the existing deadbolt. If you plan to add one, rekey the deadbolt first and the smart lock simply inherits the new key.
  • Garage entry and side door locks. Many Duarte households use the garage as the main way in, which means the garage entry lock gets used far more than the front door. Heavy use wears its pins and key faster. While rekeying it to match the rest of the house, we look for worn pins or a loose knob and fix those issues before they turn into a lockout.
  • 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.
  • Matching new hardware to your existing key. Remodels and door replacements are where one-key houses usually start drifting. If a contractor is hanging a new front door in your Duarte home, ask them to leave the lockset in the box. We'll install it and key it to your house key on the same visit, rather than letting it arrive on whatever combination came from the factory.
  • Two-key and master key options. Sometimes one key for everything isn't the right fit. A casita, home office or garage apartment may need its own key while you keep one that opens all. A small residential master key arrangement can do that, though it takes extra planning and isn't possible on every lock. Kwikset SmartKey cylinders, for example, can't be master keyed.

How Duarte shapes the job

Older homes in Duarte 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.

Inland summer heat expands metal doors and frames, which can make deadbolts drag and keys stiff. With one key used at every door, that stress concentrates on a single key. When we key a Duarte home alike, we check strikes on sun-facing doors, use a dry lubricant and suggest keeping a spare cut by code, since a worn or bent key affects every lock at once.

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 Duarte, 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.

Situations this covers

  • 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.
  • Say an older Spanish-style home near Duarte Historical Museum in Encanto 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.
  • Say the one key that opened everything was in a backpack stolen from a car at a shopping center, along with mail showing the address. Because every door shares that key, every door is exposed. We'd rekey the whole house to a new combination as soon as the schedule allows, cut fresh copies, and suggest changing the garage opener code as well.
  • For example, a house off Encanto Parkway 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. 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.
  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. 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. 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.

What affects the cost

  • How many cylinders you're matching. Price follows the number of cylinders more than the number of doors. A front door with a deadbolt and a keyed knob is two cylinders; a security screen door adds a third. A house with five doors may have nine or ten cylinders. We quote per cylinder plus the service call, so you can see how adding the gate changes the total.
  • 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. 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.

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 Duarte.

Practical tips before you call

  • Check that each deadbolt turns easily with the door closed. If you have to push or pull the door to throw the bolt, the strike is misaligned. Get that fixed during the visit, because a dragging bolt strains the key, and with one key in use everywhere, a bent key affects every door.
  • 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.
  • 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.
  • 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

  • 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.
  • 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.
  • 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.

Frequently asked questions

How long does it take to put a whole house on one key?

It depends on how many cylinders there are and what kind. Standard knobs and deadbolts go quickly once they're off the door; smart locks, handlesets and mortise locks take longer, and any lock without a working key adds time. We'll give you a realistic estimate on the phone once we know your lock count and brands.

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.

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.

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 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.

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.

How far is Duarte from your base?

Duarte is about 42 miles from our San Bernardino base, roughly 47 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.
