Rekey All House Locks in San Dimas: Doors, Gates and Codes

What to know first in San Dimas

People sometimes ask why they should rekey all house locks when only one key is known to be missing. The honest answer is that keys spread in ways nobody tracks. A standard house key can be copied at a hardware store kiosk in seconds, and a Do Not Duplicate stamp is a request, not a barrier. A key loaned to a contractor may have been copied for a helper. A key you think fits only the back door may also open the front if a previous owner keyed them alike. If you can't account for every copy, partial rekeys leave gaps you can't see. Rekeying everything at once closes them in one step, and it's far less expensive than replacing every lock, because the knobs, deadbolts, handlesets and finishes stay on your doors. The other benefit is a fresh start on key control: a known number of new keys, given to people you chose, with a written list of who holds one.

What we can do on-site

• Whole-property lock inventory. An inventory also catches locks that shouldn't be rekeyed. A slider with a wafer cylinder, a storm door handle with a proprietary key, or a worn knob gets marked for replacement or exclusion right away. You see the whole picture, with every lock and every option, before you approve a single line of work.
• Gates, fences and pool enclosures. Gate hardware lives outdoors full time, so cylinders there are often the grittiest on the property. Some clean up and re-pin well; others are rusted past saving. We tell you which is which, and where a gate lock needs replacing, we fit a weather-resistant one keyed to the same key as the rest of the house.
• Outbuildings, casitas and padlocks. A detached casita or guest house with its own entry often needs a different key from the main house, especially if someone lives in it. We can key it separately or set up a small master arrangement, so your key opens it but the occupant's key doesn't open your house. That plan comes before any re-pinning.
• Separate keys and simple master keying. Not every lock has to share a key. During a whole-house rekey we can put a home office, a storage room, a casita or a detached shop on its own key while the main doors share another. Each extra key is a small addition to the job, and it's far cheaper to plan now than to re-pin later.
• Replacing the locks that shouldn't be rekeyed. Builder-grade knobs on the most-used door often wear out before anything else in the house. When we rekey all house locks, we'll point out any that are failing and quote a replacement alongside the rekey price. You can approve it, postpone it, or ask us to re-pin it anyway for now.

What's different about San Dimas

Hillside and foothill homes in San Dimas often have multiple levels, deck doors, side stairs and retaining-wall gates, so the entry count runs higher than the doors you use daily. Wind-driven dust and ash settle into cylinders, and we clean each one as we re-pin it. Keep exits operable from inside for fire season, and make sure whoever evacuates with the family keys knows which ones matter. We plan for steep driveways when scheduling.

Houses built before 1980 in San Dimas often show their age at the keyhole: brass knobs from the 1950s, a deadbolt added in the 1980s, a mortise lock on the front door and a different brand in each room. A whole-house rekey here begins with an honest look at which pieces still work. Original mortise sets can often be rebuilt and re-pinned, while worn knobs and loose latches are better replaced. We aim to keep the character and still end up on one key.

Family homes in San Dimas tend to accumulate keys: the babysitter, the grandparents, a neighbor who waters plants and a teenager who has lost three copies of their own. A whole-house rekey brings the key count back to something you can manage. We usually suggest a small number of new keys, a keypad or smart lock code for kids and visitors, and a clear plan for who can reach the garage and side gate.

Situations this covers

• A seller wants one key for the agent's lockbox, so showings, the photographer and the inspector all use the same key. We rekey the front, back, garage entry and side gate before the sign goes up. The seller hands the new keys to the escrow officer at closing, and every earlier copy is already useless.
• Over twenty years, a family in San Dimas has handed spare keys to neighbors, a pet sitter, two babysitters, a visiting cousin and a long-gone housemate. Nobody can say who still has one. Instead of chasing each key, the couple rekeys every lock and decides to issue just three new keys, with a keypad code for anyone who needs occasional access.
• A homeowner with security screens on the front and rear doors finds that each screen takes a different key from the main doors. The mismatch means a ring of five keys for one household. During a whole-house rekey, we convert the rekeyable screen cylinders to the house key and replace the one stubborn screen lock with a model that matches.
• A homeowner uses a kit on the front and back doors, then learns months later that the garage side door still opens with the old key. Nobody wrote that door down. A whole-house count prevents exactly this gap. We list every keyhole first, including screens and the knob under the deadbolt, and the job isn't finished until each one has been tried with the new key.

Step by step with Julian's Locksmith

1. Count the keyholes before we arrive. Tell us why you're rekeying. A separation, an inherited house and years of loaned copies call for slightly different plans. Knowing the reason helps us ask about codes, remotes and hidden spares you might not think to mention.
2. Gather every key and show you belong at the address. Put every key you own on the table: house keys, garage keys, padlock keys, tiny keys for cabinets and window locks. We try each in each lock to learn what opens what. Some turn out to fit nothing, which is a useful finding.
3. Agree on the key plan before any pins come out. Choose the structure first: one key for the whole house, a second for the outbuilding, perhaps a master. We sketch it door by door and write down how many keys of each you want. Changing the plan afterward means pulling cylinders twice.
4. Rekey one door at a time and test as we go. We pull each cylinder, empty the old pins, rebuild it to the new code and reinstall it. Then we cycle it from both sides before moving on, so the house is never left with several doors half-finished while we work.
5. Cut, count and test every key. New keys are cut from the same code used to pin the cylinders. We try each key in every lock it should open, and in locks it shouldn't, to confirm the plan worked and the old keys are dead. Then you count them with us.
6. Reset what rekeying doesn't touch. Rekeying changes metal keys only. Garage remotes, keypad codes, smart lock users, alarm codes and any lockbox are separate. We walk through each with you and help with the ones we handle, so the old ways in are closed on the same day.

What affects the cost

• How long your inventory list turns out to be. Larger properties cost more because they take more time and more parts. Outbuildings, multiple gates and a second dwelling all lengthen the job. For an accurate quote, send a list or photos and tell us which doors you use every day.
• Condition of the oldest and cheapest locks. Builder-grade knobs, gate latches and slider cylinders are the usual troublemakers. They may re-pin, but a worn latch will fail again soon. We point out which ones are worth rekeying and which are better replaced, and you decide. Nothing is swapped without your approval.
• Locks at the edge of the property. Padlocks are the swing factor. If yours have rekeyable cylinders, they take little time. Budget padlocks that can't be rekeyed must be replaced with new ones keyed alike. Bring a list or let us count them on the walk-through. Gate and shed locks see the most weather, so they are often the ones that need replacing.

What to do before we arrive

• Tell the people who legitimately need access before the rekey, and hand out their new keys the same day. A mother-in-law who can't get in the next morning is a more common headache than a break-in. Write down who needs what: pet sitter, gardener, grown kids.
• Retire the hide-a-key. Fake rocks, planter bases and doormat spots are the first places a burglar looks. Give a spare to a trusted person, or switch visitors to a keypad code you can change. If you do keep a key outside, lock it in a hardened box.
• Keep house keys off the ring you hand to valets and mechanics. A shop can copy a house key as easily as a car key, and a parking attendant sees your registration and your address. Carry a small separate key for the car and keep the house key in your pocket.
• Ask about your mailbox separately. A private mailbox has its own small key and can usually be rekeyed or replaced. A cluster box belongs to the postal service or the HOA, and its locks follow their rules. Don't lump either one into your house key plan.

What not to do

• Forgetting the codes, fobs and hidden spares. New metal keys don't change a garage keypad, a smart lock user list, a lockbox left from a sale or a spare in the planter. Walk the list of other ways in, and reset each one the same day.
• Spending a rekey on a failing lock. A knob with a worn latch or a deadbolt chewed up by a past break-in will keep failing no matter how new the key is. Replace the weak hardware and key it to match, instead of nursing it along.
• Skipping the garage side door and the door from the garage into the house. These two are among the most commonly lent out and the most commonly forgotten. If either one stays on the old key, anyone holding that key still has a way into your home.
