Why Preston Locksmith & Security Is San Carlos’s Preferred Rekey Locks Company

San Carlos homeowners deal with a specific kind of lock problem: 1920s to 1950s bungalows packed onto 50-foot-wide lots, where exterior doors still carry the hardware installed generations ago. That means mismatched cylinders, short-throw deadbolts, and keys cut by three different shops. We have been sorting this out since 2008 as part of the Relay Home Co. family, and every San Carlos job is handled by a background-checked, uniformed technician, not an anonymous subcontractor. The Relay Visibility Guarantee is standard: a written price before work begins, a live trackable arrival time, before-and-after photos, and a written guarantee on every repair, including a free second visit if the repair fails.

San Carlos customers consistently tell us the deciding factor is that the price they were quoted on the phone is the price on the invoice. That is not a perk. That is the minimum standard. Kevin Yoon runs our operation with one rule: a rekey quote covers the full job, every exterior door, every cylinder with a keyway, no trip charge materializing on the doorstep. Dispatch and scheduling are coordinated from the brand’s San Francisco Bay Area office, and crews serve San Carlos locally, typically arriving within 45 to 60 minutes for non-emergency rekey work.

Locksmith Rekey in San Carlos

Locksmith rekey in San Carlos means pulling the internal pins from an existing lock cylinder and swapping them so old keys stop working, no new hardware required. The process takes 15 to 30 minutes per cylinder in most San Carlos homes, and it is the right call after a tenant moves out, a cleaner or contractor returns a key, or you simply do not know how many copies of your house key exist. In a dense grid of 1920s to 1950s bungalows, rekeying is almost always cheaper than replacing, as long as the cylinder itself is still functional. A standard Schlage or Kwikset deadbolt rekey in San Carlos runs $95 to $160 for the first cylinder and $25 to $40 for each additional one keyed to match.

Multi-Door Rekey to One Key

Most San Carlos homes have at least two exterior doors, and often a side door, garage service door, or back porch entry. We quote the entire job on the phone: how many cylinders, how many keys, what it costs, written down, before anyone gets in a truck. The written quote is the invoice amount. If you want the front deadbolt, side door knob, and garage entry all turning on one fresh key, that is mechanically simple and we tell you the number in advance.

Non-Destructive Entry and Rekey

If you are locked out and need a rekey at the same time, our tech picks the lock open without drilling whenever the cylinder is intact. Drilling destroys hardware and turns a $25 rekey into a $90 replacement, and it is the thing a shady locksmith does fastest. Our policy in San Carlos: pick first, replace only if the cylinder is genuinely worn out, and always show you what we are doing before we do it.

Rekey Door Lock in San Carlos

Rekey door lock in San Carlos usually means one of two situations: a single exterior door after a key is lost or a new house purchase where the prior owner handed over a ring with six keys and no labels. The job is the same either way: remove the cylinder, replace the driver pins and springs, cut fresh keys, test the throw, and hand you written confirmation of what was done. In San Carlos specifically, we often see bungalows where the front door is Schlage and the side door is Kwikset, keyed by different people at different times, leaving homeowners juggling three keys for two doors, as we found on a 1940s bungalow off Laurel Street. Our tech pulled the lock cylinders, re-pinned them to a single new Kwikset key, and left the old keys dead, all agreed at the price we quoted before dispatch. No drilling, because the pin and tumbler were intact once we cleaned out the old graphite.

When a Rekey Is Not Enough

Some San Carlos homes have a 60-year-old mortise lock with a stripped set screw or a cylinder so worn the pins will not hold a new key. Rekeying that is a waste of your money. We tell you straight when a replacement is the honest fix, and we show you the worn parts before you pay for anything.

Rekeying After a Key Goes Missing

If a key goes missing in San Carlos, a rekey is the affordable security reset. You do not need new hardware. You need every old key rendered useless. We do that in one visit, quote the whole job first, and hand you all new keys cut to the new pinning.

Trusted Brands We Service in San Carlos

For San Carlos customers, that usually means Schlage and Kwikset deadbolts on bungalow doors, plus the occasional Mul-T-Lock or Medeco cylinder on a deadbolt a prior owner upgraded.

If your lock has a brand name stamped on the face, we almost certainly have the parts on hand.

Common Rekey Locks Problems We See in San Carlos Homes

• Mismatched cylinders across exterior doors. The front door is Schlage, the side door is Kwikset, and the deadbolt on the back is something else entirely. Three keys for two doors is normal in older San Carlos homes, and the fix is re-pinning everything to one key.
• Short-throw deadbolts on warped door frames. Many 1920s to 1950s bungalows have deadbolts that only throw half an inch, and the door frame has settled by a quarter inch over eight decades. A rekey works fine, but the door may need a strike plate adjustment at the same time.
• Stripped set screws on old mortise locks. A 60-year-old lock with a stripped set screw will not hold a new pinning. The honest answer is replacement, not another rekey, and we show you the part before we quote it.
• Phone quotes that exclude the second and third exterior door. A price that sounds cheap but only covers one cylinder, then the tech arrives and charges for two more. Our quote covers every exterior door from the start.
