Fast, Reliable Rekey Locks Across Simi Valley
When you need a lock rekey in Simi Valley, you want three things: a real price before anyone shows up, a tech who arrives when they say they will, and old keys that stop working the same day. That’s exactly how we work at Preston Locksmith & Security. A standard house rekey in Simi Valley runs $95 to $180 for labor, plus $20 to $35 per cylinder, with the full written price confirmed on the phone before dispatch. We serve every part of Simi Valley, from the 93065 zip around Sycamore Drive to 93063 near Wood Ranch, and our phone is answered by a live person 24/7 at (409) 405-4485.
Why Preston Locksmith & Security Is Simi Valley’s Preferred Rekey Locks Company
Simi Valley homeowners call us because we do something most locksmiths in this city won’t: we fix the price in writing before the tech leaves the shop. No dispatch fee that doubles on arrival. No “well, actually” when the invoice comes. The number we quote on the phone is the number on your digital invoice, backed by our written guarantee on every repair.
Kevin Yoon leads our team, and he’s built the service around one standard: a customer should be able to identify the tech before they open the door. Every rekey job in Simi Valley is performed by a background-checked, uniformed technician whose name and photo you receive before arrival. Our live tracking link shows exactly where the van is, so you’re not stuck waiting through a four-hour window.
We’ve worked on locks in houses off Madera Road, condos near the Simi Valley Town Center, and ranches throughout the valley floor. Every job gets before-and-after photos delivered digitally, so you see the work you paid for. The Rekey Locks team treats your existing hardware with respect: if a cylinder is serviceable, we re-pin it. We don’t push replacement hardware you don’t need.
Rekey House in Simi Valley
A Rekey House in Simi Valley means changing the internal pins in every exterior lock so that every existing key stops working, while the hardware stays exactly where it is. Homeowners here do this after moving into a home on the east side near First Street, after a tenant leaves a rental off Tapo Canyon Road, or when a house key has been floating around on too many keychains for too long. No new knobs, no new deadbolts, no patching holes. Just fresh pins and new keys.
What the Job Involves
We remove each lock cylinder, swap the internal pins to match a new key code, then test every lock twice: once with the new key, once with every old key you hand us. On a typical three-lock Simi Valley house, the whole job runs 45 to 75 minutes on the doorstep, and you’re left with fresh keys that run every exterior lock.
When Homeowners Need It
The most common trigger here is a real estate closing. Between the mid-1960s ranches off Sycamore Drive and the 1980s two-story tracts in Wood Ranch, Simi Valley has a lot of original builder-grade Kwikset and Schlage pin and tumbler cylinders still in service, so a rekey often means re-pinning hardware that has never been touched since the model home opened. Prior owners, housekeepers, pet sitters, and grown kids all may have copies. A rekey erases that key inventory in under an hour.
Lock Rekey in Simi Valley
A Lock Rekey in Simi Valley is similar to a house rekey but often covers a smaller scope: a single bedroom door, a detached garage off the alley behind Los Angeles Avenue, or a side gate to the backyard. You keep the same physical lock, we change only the pins inside the cylinder, and you get new keys that work in that lock only. Cost is $20 to $35 per cylinder in Simi Valley, with a $95 minimum labor charge per visit.
Single-Cylinder Work
If you’re rekeying one exterior door because a handyman you once hired never returned a key, we quote a single flat fee upfront. No minimum job-size games, no “while I’m here” upsell. We show up with a written price, re-pin the cylinder, and hand you the new keys with a completed invoice before we leave.
Multi-Door Consistency
Many Simi Valley homeowners want one key for the front door, the door into the house from the garage, and the side gate. That’s a keyed-alike rekey, and it’s the single most common request we get in this city. We quote the total keyed-alike price before dispatch, so there’s no surprise line item for a second or third cylinder.
Trusted Brands We Service in Simi Valley
Our techs work on the hardware already installed in Simi Valley homes, which mostly means Kwikset, Schlage, and Baldwin for residential, plus Medeco and Yale on some higher-security and commercial doors. We stock common pin kits and springs for these brands on the truck, so there’s no “we’ll have to order parts” delay on 90% of house rekeys. If you have an older Baldwin mortise lock from a 1970s custom home off Santa Susana Knolls, we can re-pin it without swapping the trim. If it’s a Medeco high-security cylinder on a business door near the 118, we’ll quote it the same way: written price first, work second.
Common Rekey Locks Problems We See in Simi Valley Homes
- Old keys still work after a DIY rekey. Homeowners swap the pins but never test every old key in the cylinder, and the prior owner’s spare works fine on move-in day. We test every cylinder twice before we call the job done.
- Locks bind after a cheap rekey. Builder-grade Kwikset cylinders from 1980s Wood Ranch homes get re-pinned without being cleaned or lubricated first, and six months later the key sticks. We clean every cylinder before re-pinning it.
- One key for three doors turns into “I’ll need to order something.” That code phrase usually means the tech doesn’t stock the pin kit for your brand. Our vans carry the common Simi Valley hardware kits as standard.
- Multi-cylinder quote that climbs on arrival. A common frustration here: the phone quote didn’t mention a service call fee or every cylinder, and the on-site total is double. We send a written, itemized price before dispatch. That’s the whole point.

FAQs About Rekey Locks in Simi Valley
Most house rekeys in Simi Valley take 45 to 75 minutes on the doorstep, from the first door to the final test. A three-lock home off Madera Road or near the Town Center runs closer to an hour because we test every old key against every cylinder. We confirm the price before anyone is dispatched, and we don’t add a call-out surcharge on arrival.
No. If you’re locked out and need the lock opened before a rekey, we pick the cylinder first. Drilling is a last resort for failed hardware, and we explain the cost in writing before doing it. For a rekey alone, we don’t need to drill anything.
Yes, and that’s the preferred path for the mid-century ranches and 1980s tract homes across Simi Valley. We re-pin your existing Kwikset, Schlage, Baldwin, or Yale cylinders, and the hardware stays in place. Replacement only comes up when a cylinder is visibly worn, and we show you the issue before quoting any new part.
We rekey Kwikset, Schlage, Baldwin, Yale, and Medeco hardware, including the original builder-grade Kwikset pin and tumbler cylinders common in Simi Valley homes. Our vans carry the pin kits and springs for these brands, so the job gets done in one visit.
Before the tech arrives, you get a text with their name and photo, plus a live tracking link showing the van’s location. When they knock, they’re in uniform and they introduce themselves by name. Kevin Yoon set this standard from day one: if the person at your door doesn’t match the photo we sent, do not open the door. Call our dispatch line at (409) 405-4485 and we’ll verify instantly.
