Lost your key or dealing with a lock that won’t turn? A residential locksmith in Campbell typically arrives within 30 to 45 minutes, and the work usually runs $65 to $220 depending on what’s needed. That’s the honest range, and we put it in writing before anyone touches your door. Preston Locksmith & Security has been handling Campbell’s locks since 2008, and we work on everything from 1940s cottage hardware near the Pruneyard to newer homes up toward San Tomas Park. Call (409) 405-4485 and a live person answers, day or night.

Why Preston Locksmith & Security Is Campbell’s Preferred Residential Locksmith Company
Campbell homeowners call us because we show up when we say we will and we charge what we quoted. The Relay Visibility Guarantee is the backbone of every job: a written price before work begins, live arrival tracking on your phone, photos of the work when it’s done, and a 365-Day Done Right Promise.

Our Residential Locksmith team dispatches from the San Francisco Bay Area office and serves Campbell locally. Response times to most Campbell neighborhoods, including the blocks near downtown, the Winchester Boulevard corridor, and the area around San Tomas Park, run 30 to 45 minutes. When you book, you’ll know who is coming, what they look like, and when they’ll knock.
Being local to the region means our techs understand Campbell homes specifically. A lockout on a 1960s block home near Rosemary Lane is different from one in a downtown cottage built during the fruit-shed era. We carry pinning kits and hardware that match both. Kevin has built this operation around one rule: never send a technician to a Campbell door without the parts and knowledge to actually fix it that day.
Lost Key Replacement in Campbell
Lost Key Replacement in Campbell means getting you back inside and then making sure that lost key no longer works. It is not the same as a lockout. When a key is genuinely lost rather than just locked inside, the smart move is either rekeying the lock or replacing it entirely. In Campbell, rekeying a standard deadbolt or knob usually runs $25 to $40 per lock, while replacing a deadbolt with new hardware runs $90 to $180 installed. We write the exact number on the estimate before we start.
When Rekeying Beats Replacement
If the lock itself is in good shape and you just lost the key, rekeying is the cheaper and faster option. It means swapping the internal pins so the old key no longer turns, no new hardware needed. This takes 10 to 15 minutes per lock on most Campbell homes. If the lock is worn, damaged, or you want an upgraded deadbolt, replacement makes more sense. We’ll tell you which one we’d choose for our own door and why.
Key Control After a Lost Key
When a key goes missing somewhere in Campbell, whether at the farmers market, a trail in Los Gatos Creek County Park, or somewhere between the car and the front door, the real question is whether that key can be linked to your address. If it can, rekeying is the only responsible move. We can also set you up with a restricted keyway from Medeco or Yale so nobody can cut a copy without your authorization. That’s standard key control, and it’s a service most big-box stores in Campbell do not offer.
House Key Locksmith in Campbell
A House Key Locksmith in Campbell handles the full range of key work: cutting new keys, rekeying existing locks, and getting multiple doors onto one key. This is the work we do most often for homeowners in Campbell, especially after they buy a house or when a tenant moves out. The price for cutting a standard house key runs $4 to $10 per key, while a full rekey of two to three doors typically runs $65 to $120 total.
One Key for Every Door
A surprising number of Campbell homes have two or three different keys for the front, back, and garage entry. It does not have to be that way. We can rekey every lock in the house to work off a single key in about 30 to 45 minutes. This is particularly common after a home purchase in older Campbell neighborhoods, where previous owners added locks piecemeal over decades. One key, every door, done before lunch.
Replacing Worn House Keys
A worn key is a lockout waiting to happen. If your Campbell home’s key is hard to insert, needs jiggling, or has visibly flattened teeth, it’s already failing. We cut new keys from code or from an existing working copy. If no working key exists and the lock is original to a 1950s or 1960s Campbell home, we can disassemble the cylinder, decode the pins, and cut a fresh key to fit. Most of the time, this costs less than $30 and saves a drill-out later.
Trusted Brands We Service in Campbell
Our techs are trained and equipped to service Kwikset, Medeco, Yale, and Baldwin hardware, plus Schlage, Sargent, Mul-T-Lock, and Abloy. That matters in a city like Campbell, where the housing stock spans decades and so does the door hardware. A 1940s cottage near downtown might have a Baldwin mortise lock, while a 1980s condo near Winchester has a Kwikset deadbolt. We stock parts and pinning kits for both ends of that spectrum, so the job gets done in one visit.
Common Residential Locksmith Problems We See in Campbell Homes
- Mismatched hardware on the same house. Campbell’s age-mixed housing stock means a single property can have a 5-pin Kwikset knob on the front door and an old Sargent mortise lock on the back. You’d need two different service calls from two different companies to handle that, unless you call us. We carry pinning kits and parts for both on the same truck.
- Deferred hardware replacement near downtown. Campbell’s permit desk requires a permit for a full door replacement but not for rekeying or cylinder swaps. So homeowners near downtown keep old door hardware in place longer than they should. We routinely service mortise locks that haven’t been opened in 30 years.
- Lockouts after a key linked to the address goes missing. Whether it fell out of a pocket at The Pruneyard or was left in a room that got re-keyed after a roommate left, the fix is rekeying. We see this all over Campbell, from the cottage blocks near downtown to the newer developments off Winchester.
- Bump-resistant deadbolts replaced with no-name locks. A previous owner or a fly-by-night handyman installs a budget deadbolt with no ANSI grade rating and an incompatible keyway. It looks fine from the outside, but it’s actually weaker. We replace these with Grade 1 hardware from Kwikset, Medeco, or Baldwin, matched to the rest of the house’s keying.

FAQs About Residential Locksmith in Campbell
A background-checked, uniformed technician arrives with a live arrival time you can track on your phone.

If both doors are keyed alike and the locks are in decent shape, rekeying is almost always the better move. It costs $25 to $40 per lock, keeps your existing hardware, and puts both doors onto a new key the old one can’t turn. Replacement only makes sense if a lock is failing, stripped, or you want better security. We’ll look at both doors and tell you which we’d do on our own Campbell house, and the written price covers either path before we start.
Yes. We service original mortise locks in Campbell’s older homes all the time, especially in the 1940s and 1950s cottage blocks near downtown. A mortise service means opening the lock body, cleaning out decades of hardened grease, replacing worn pins and springs, and reassembling it to work smoothly. It runs $110 to $220 depending on what’s worn. Replacement is only needed if the lock body is cracked or the internal parts are broken beyond repair.
No. If we can’t open your Campbell door without damage or can’t service the lock as quoted, you don’t pay for the service call. That’s part of the 365-Day Done Right Promise and The Relay Visibility Guarantee. We don’t charge a call-out fee on top of a repair. The price we agree on before the job is the price on the invoice.
