Fast, Reliable Rekey Locks Across Hillsborough
If you just moved into a Hillsborough home or you’re done with keys floating around after a remodel, rekeying is the fastest way to make every old key dead. A rekey swaps the internal pins inside each lock cylinder so existing keys stop working, and you get a fresh set. No new hardware needed. In Hillsborough, most rekey jobs run between $85 and $180 per cylinder depending on whether we’re dealing with a standard Schlage deadbolt or an old mortise lock, and the written price is confirmed before we dispatch anyone. Call (409) 405-4485 and we’ll walk you through what your specific doors need.
Hillsborough is not like the rest of the Peninsula. There are no streetlights and no sidewalks. Nearly every home sits behind a gate or down a private lane off roads like Hayne Road, Black Mountain Road, and Crystal Springs Road. That changes how a locksmith actually gets to your door. We know this because we work here all the time. Our techs expect the intercom, expect the gate code, and know to ask which door your family actually uses before they start pulling cylinders.
Why Preston Locksmith & Security Is Hillsborough’s Preferred Rekey Locks Company
Hillsborough homeowners tend to ask the same three questions before booking: who exactly is coming, what’s the real price, and when will they get here. We answer all three before a single tool leaves the bag. Every technician is background-checked, arrives in uniform, and sends a live, trackable arrival time through The Relay Visibility Guarantee. You’ll see a written price first, you’ll get before-and-after photos of the cylinder work, and every job includes the 365-Day Done Right Promise. If it’s not done right, we make it right, with a free second visit if the repair fails.
We built our Hillsborough reputation on jobs where homeowners had been burned before by phone estimates that changed at the door. That doesn’t happen with us. Kevin Yoon, who leads the Preston Locksmith & Security team, has trained our techs to quote honestly from the start. A mortise lock takes longer than a modern deadbolt. A Baldwin cylinder costs more to rekey than a standard Kwikset. We tell you that on the phone, not as a surprise line item when the tech is already standing in your entryway.
Our technicians service lock hardware from Abloy, Medeco, Schlage, and Baldwin and carry the pin kits and cylinder parts Hillsborough homes actually need. Mid-century mortise locks, modern ANSI Grade 1 deadbolts, high-security commercial cylinders. When you call about Rekey Locks, you’re talking to someone who knows what your front door was built with.
Rekey Door Lock in Hillsborough
Rekey Door Lock work in Hillsborough usually means more than one door. The formal front entrance might be a Baldwin mortise lock from the 1960s, while the rear kitchen door and garage entry are modern Schlage or Kwikset deadbolts from a recent addition. A rekey in this scenario means pulling each cylinder, re-pinning it to a new key, and then cutting fresh keys that work across all of them. The cost per cylinder runs $85 to $180, and because the tech is already inside your gate, doing two or three doors in one visit is almost always the smart move.
Mortise And Deadbolt Key Matching
Old mortise locks and newer deadbolts can be keyed alike, but they need different pin kits. That’s the number one thing a cut-rate phone quote gets wrong. We know before we arrive what your entryway actually has, and the written price reflects it.
Rear And Garage Entry Doors
Hillsborough families rarely use the formal front door day to day. The rear door by the pool, the garage side door, the mudroom entry off the kitchen. Those are the cylinders that actually need to match the front, and they’re the ones a previous homeowner’s contractor, housekeeper, or dog walker still has a key to. We rekey all of them in one visit.
Rekey Service in Hillsborough
Rekey Service in Hillsborough covers the full job from the gate intercom to the final key test. When you book, you get a written estimate before dispatch, a live arrival time you can track, and a tech who’ll call or buzz at your gate when they arrive. The work itself typically takes 30 to 60 minutes for a front-and-rear-door rekey on a standard Hillsborough property. If you have several outbuildings, a detached studio, or a wine cellar door with its own deadbolt, add a few minutes per cylinder.
Gate And Intercom Access
Since most Hillsborough homes are set back off private lanes, our techs are used to being buzzed in and ID’d at the intercom. You’ll know their name, what they look like, and when they’re pulling up before they ever ring. The Relay Visibility Guarantee gives you a live map, not a four-hour window.
New Homeowner Rekey
We were called to a home on Hayne Road where a family had just closed and the seller’s contractor keys were still out there somewhere. The front door was a Baldwin mortise lock, the kitchen and rear entries were Schlage deadbolts. Our tech pulled all the cylinders, re-pinned everything to a fresh key control set, and matched a bump-resistant keyway to the rear door since that was the one left unlocked on the way to the pool. No drilling, no new hardware, and the old keys were dead the same visit.
Trusted Brands We Service in Hillsborough
Hillsborough properties run the full range: original mid-century Baldwin hardware, newer Schlage smart deadbolts, Kwikset cylinders on garage entries, and Medeco high-security locks on wine rooms and home offices. We carry pin kits, cylinder parts, and tailpieces for Schlage, Kwikset, and Medeco on the truck, which means most rekey jobs finish in one visit without a follow-up parts run. If your lock brand isn’t on the list, mention it on the phone and our techs will confirm coverage before they head to your gate.
Common Rekey Locks Problems We See in Hillsborough Homes
- Front door rekeyed, rear door forgotten. The formal entry gets fresh pins while the kitchen or rear door still works with the old key. We always ask which doors your family actually uses and rekey all of them in the same visit.
- Phone quote changes at the gate. A cut-rate outfit quotes a per-cylinder price without knowing whether your entry is a mortise lock or a modern deadbolt. Mortise rekeys take longer and need different pins. Our written quote is locked before dispatch, not renegotiated on your doorstep.
- Unverified techs at the intercom. On gated properties, homeowners sometimes turn away a legit technician because the person at the intercom doesn’t match the company name on the booking. Our techs arrive uniformed, background-checked, and you’ll already have their name and photo in the booking confirmation.
- Mixed hardware from different eras. A 1950s addition might have original mortise cylinders while the new wing has ANSI Grade 1 deadbolts. Both can be rekeyed to one key, but not with the same pin kit. We diagnose this on the phone so the written price already covers the real job.
Pricing for Rekey Locks in Hillsborough, CA
Rekeying a standard Schlage or Kwikset deadbolt in Hillsborough typically runs $85 to $130 per cylinder. A mortise cylinder or a Baldwin lockset runs higher, usually $140 to $180 per cylinder because the pinning work takes longer and uses specialized parts. Key cuts and new keys are included. If you have three doors, expect the job to land in the $255 to $400 range total, confirmed in writing before anyone leaves our office.
