Fast, Reliable Rekey Locks Across San Pablo
If you’ve handed out keys to a tenant, a contractor, a dog walker, or a previous owner and now need those keys to stop working, a lock rekey in San Pablo is the fix. Rekeying means we swap the internal pins inside your existing lock cylinder so old keys no longer turn it, without replacing the hardware itself. A standard single-cylinder rekey in San Pablo runs $25 – $45 per lock, and most homes with two or three doors are done inside an hour once we arrive. Call us at (409) 405-4485 and you’ll get a written price before we dispatch anyone to your door.
We know San Pablo’s streets, from the fourplexes off Rumrill Boulevard to the single-family blocks near Contra Costa College, and we schedule our routes so we’re not making you wait through a four-hour window you can’t track.
Why Preston Locksmith & Security Is San Pablo’s Preferred Rekey Locks Company
Kevin Yoon founded Preston Locksmith & Security in 2008, and the business has stayed focused on one thing: showing up when we say we will, with a price that was locked in before we left the shop. San Pablo customers call us because we answer the phone with a live person, send a background-checked uniformed technician, and back every job with the 365-Day Done Right Promise. If the rekey isn’t done right, we return and make it right, no charge, no argument.
Our Rekey Locks team works with the housing mix San Pablo actually has, not just the newest deadbolts in the showroom. A landlord near Rumrill Boulevard with a 1950s fourplex is dealing with different hardware than a homeowner near San Pablo Avenue with a 2005 Schlage deadbolt. We carry pin kits for Kwikset, Schlage, Yale, and Baldwin on the truck, plus the older keyways that mid-century mortise locks still use. That means one visit, not a callback because we didn’t bring the right pins.
No anonymous subcontractor shows up at your door. You’ll know the technician’s name, see a live trackable arrival time, and get before-and-after photos of the work. That’s The Relay Visibility Guarantee, and it’s included on every job in San Pablo.
Lock Rekey in San Pablo
A Lock Rekey in San Pablo is the most common job we handle for both homeowners and landlords along the San Pablo Avenue corridor. We remove the cylinder from the door, replace the internal pins and springs so the old keys no longer match, reassemble the lock, and test it with new keys. The original hardware stays in place, which matters when you have a mortise lock that’s been in the door since the Eisenhower administration and you don’t want to route out new wood just to change access.
You’d want this after buying a home anywhere in San Pablo, after a tenant moves out of a unit near Rumrill Boulevard, after a breakup where the other person kept a key, or after a contractor finished a remodel and never returned the copy you handed them. The cost for a standard deadbolt or knob rekey is $25 – $45 per cylinder, and we confirm the exact number in writing before we start turning pins.
Deadbolt Rekey for Security
Most San Pablo front doors have a deadbolt above the handle, and that’s the lock doing the actual security work. We rekey it in place, cut new keys to match, and if the original keys are missing entirely, we still don’t replace the deadbolt unless you ask us to. No upsell, just the pins swapped and the keyway restored to working order.
Mortise Lock Rekey Without Replacement
Older San Pablo homes and small apartment buildings often have mortise locks, which are rectangular lock bodies recessed into the door edge rather than a round cylinder screwed to the face. These can absolutely be rekeyed, but the job is slower and involves a different pin kit than a modern Kwikset or Schlage deadbolt. Expect $35 – $65 per mortise lock, quoted in writing before we begin.
Locksmith Rekey in San Pablo
A Locksmith Rekey in San Pablo is what you call for when you have multiple locks on one property that all need to work from a single new key, or when you need old keys invalidated right now and don’t want to wait for a hardware store to cut blanks. We handle the full scope: remove cylinders, install matching pins, cut new keys on site, test every lock, and hand you the old keys back as scrap metal if you want them.
Call us at (409) 405-4485. You’ll get a live person, a same-day or next-day slot in San Pablo, and a written price before any technician is dispatched. If the door turns out to have an old mortise lock instead of a standard deadbolt, the quote gets adjusted openly, not sprung on you at the invoice.
Single-Key Convenience for Homes and Fourplexes
We regularly key multiple locks alike in San Pablo so your front door, back door, and side gate all work off one key. On a fourplex, we can key each unit’s deadbolt and knob to separate tenant keys while keying the common laundry room or front gate to a master key that opens all of them. That setup is common for landlords along Rumrill Boulevard and near the San Pablo Civic Center.
Rekey After Tenant Turnover
We got a call from a landlord on Rumrill Boulevard whose fourplex had just turned over two units in the same week. The existing deadbolts were mixed, one Kwikset, one older mortise lock, and the prior tenants’ keys were still floating around. We rekeyed both lock cylinders on site, cut fresh keys for the new tenants, and left the original hardware in place instead of upselling replacements.
Trusted Brands We Service in San Pablo
San Pablo homes carry a mix of hardware, from modern Kwikset deadbolts on newer construction near El Portal Drive to Yale and Baldwin mortise locks in the older tracts off Rumrill Boulevard. We stock pin kits and key blanks for all of them on the truck, so a rekey doesn’t turn into a second appointment because we didn’t bring the right parts. If you’ve got Medeco high-security cylinders on a commercial door or a Baldwin handleset on the front entry, we can service those too and cut the corresponding keys on site. You won’t hear us say we need to order something and come back later.
Common Rekey Locks Problems We See in San Pablo Homes
- Mixed hardware on the same property. A 1950s house off Rumrill Boulevard might have a Baldwin mortise lock on the front door and a Kwikset deadbolt on the back. We rekey both to the same key without replacing either, but the job takes longer than a two-minute deadbolt swap.
- Old keys still in circulation. After a tenant leaves a San Pablo fourplex, ex-roommates, contractors, and former caretakers often still have copies. Rekeying is the only way to invalidate every single one without knowing who has what.
- Quotes given before the lock is identified. Some locksmiths quote a flat rekey rate over the phone and then bump it on site when they discover an older mortise lock. We ask what type of lock you have when you call, and if you’re not sure, we give you a range in writing before dispatch and adjust openly, never at the invoice without explanation.
- Keys kept “just in case” after a rekey. If you keep a pre-rekey key on your keyring, you’re carrying the exact key you paid to invalidate. We mark the new keys and suggest you destroy the old ones, especially if a prior tenant or contractor had access.
Pricing for Rekey Locks in San Pablo, CA
A standard lock rekey in San Pablo runs $25 – $45 per cylinder for most Kwikset, Schlage, Yale, and Baldwin deadbolts and knobs. Mortise locks run $35 – $65 each because the labor and pin work are heavier. If you have multiple locks, the per-lock price drops slightly, so a typical San Pablo home with three doors is usually $60 – $100 total. We also charge a one-time trip fee for San Pablo calls, which is quoted in writing on the phone before anyone is dispatched. You will not see a new fee added when the technician arrives. The price we put in writing is the price on the invoice, and you can call (409) 405-4485 for a free estimate right now.
