Fast, Reliable Lock Installation & Rekey Across San Mateo
Lock installation and rekeying in San Mateo usually runs between $95 and $260 per lock, depending on the hardware grade and whether we’re working with a standard cylindrical prep or an older mortise pocket. We can typically reach most San Mateo neighborhoods within 30 to 45 minutes for scheduled work, and our emergency response to areas like Beresford, Baywood, and the Caltrain corridor is often faster. Since 2002, Novak Lock & Security has quoted every job in writing before a technician leaves the shop, and the price on the phone is the price on the invoice. Call (331) 310-8471 and we’ll tell you the exact number before anyone is dispatched.
Why Novak Lock & Security Is San Mateo’s Preferred Lock Installation & Rekey Company
San Mateo’s housing stock is specific. We work on 1950s tract ranchers in Beresford, post-war bungalows in Fiesta Gardens, and 1960s apartment buildings along the Caltrain spine that still carry original master-key systems far past their intended service life. That local familiarity means we arrive already knowing what’s likely behind the door: a worn Kwikset cylinder, a corroded Schlage strike, or a door prep that needs a reinforcement plate before any smart lock goes on.
Every San Mateo job is handled by a background-checked, uniformed technician working under The Haven Standard, the same documented quality framework applied across all ten Haven brands. We leave a photo record of the finished work on every visit, not as an upgrade, but as standard procedure. That’s Haven Standard Clause 7: the customer gets written documentation of what was done, with photos, before we leave the property.
Daniel Novak founded this company on one rule that hasn’t changed in over two decades: the price quoted on the phone is contractually binding. No dispatcher here is allowed to give a vague range and let the technician “assess on arrival.” That practice is the single biggest source of bait-and-switch pricing in the locksmith trade, and it’s exactly what we built this business to eliminate.
Our Lock Installation & Rekey Services in San Mateo
Smart Lock Installation
San Mateo’s heavy concentration of tech-industry professionals means we install more smart locks here than in any of the surrounding Peninsula cities. A typical smart lock retrofit on a San Mateo door runs $180 to $340, which includes the hardware, installation, and an honest assessment of whether your existing door prep can support the lock properly. Many older San Mateo ranchers have door preps drilled for a 2-1/8″ cylindrical deadbolt, and we’ll tell you plainly if the frame needs reinforcement before a Yale Assure or Schlage Encode goes on. That’s the difference between a smart lock that works for ten years and one that jams in six months.
Keyless Entry
Keyless entry systems on San Mateo’s east side face a specific enemy: the marine layer. Keypads mounted on northeast-facing doors absorb ambient humidity that settles over the Bayshore, and budget keypads corrode from the inside out. We install keyless entry hardware rated for exterior coastal exposure, and we generally recommend keypad deadbolts with a physical key override for exactly this reason. Typical keyless entry installation in San Mateo runs $210 to $390, depending on whether we’re adding a standalone keypad deadbolt or an integrated smart lock system.
Keypad Lock
A keypad deadbolt on a 1960s San Mateo rancher is a smart upgrade, but only if the strike plate and frame are solid. We regularly see keypad locks installed on original frames with nothing but a 1/2″ screw into soft framing lumber, which means the deadbolt is decorative, not protective. When we install keypad locks on older San Mateo homes, we reinforce the strike with a hardened cup and 3″ screws into the stud as standard practice. That’s included in the price, which typically runs $160 to $310 for a residential keypad deadbolt installed and programmed. We’ll also set up any user codes and show you how to manage them before we leave.
Biometric Lock
Biometric locks on San Mateo properties are still relatively uncommon compared to the tech-adoption rate in new construction, but we’re seeing more requests from homeowners in Baywood and the western hills who want fingerprint access on their primary entry. These installations require precise alignment between the fingerprint sensor, the deadbolt throw, and the door prep; if any one of those is off by a millimeter, the lock reads fine in testing and fails in daily use. We quote biometric lock installation in San Mateo at $290 to $520, depending on the hardware grade and whether we’re replacing an existing deadbolt or cutting a new prep. We stock Baldwin and Schlage biometric models locally for fast turnaround.
We also handle electronic locks, key duplication, and full rekeying of existing hardware. If you’ve lost a key, bought a home in San Mateo and don’t know who else has copies, or simply want one key that operates every door, a rekey runs $18 to $35 per cylinder, quoted in writing before we start.
Trusted Brands We Service in San Mateo
We stock parts for the brands San Mateo homeowners actually use: Schlage, Kwikset, Baldwin, and Mul-T-Lock are the most common in the single-family neighborhoods, while Sargent and Best dominate the commercial and apartment stock near the Caltrain corridor. For high-security work, we cut and program Medeco and Mul-T-Lock restricted keys locally, which matters when you don’t want to wait a week for a key by mail. If a lock can be rekeyed or retrofitted, we’ll do it onsite. If it can’t, we’ll say so and quote the replacement in writing.
Common Lock Installation & Rekey Problems We See in San Mateo Homes
- Salt-air corrosion inside pin-and-tumbler cylinders. The marine layer that funnels through the Bay and settles over San Mateo’s east side carries enough salt and ambient moisture to corrode the pin springs inside a lock cylinder faster than most homeowners realize. Keys start sticking, the plug won’t turn, and eventually the key snaps off in the cylinder. This is the single most common service call we get in San Mateo, and it usually requires a cylinder replacement and rekey rather than a simple lubricant fix.
- Pitted and rusted gate hardware on east-facing properties. Homes on the lower-elevation east side near the Bayshore marshes face northeast and take the marine layer head-on. Exposed padlocks, gate latches, and door strikes pit and rust within two to three seasons if they’re not stainless or marine-grade. We replace them with corrosion-resistant hardware and coat the adjacent surfaces properly.
- Worn master-key systems in 60s and 70s apartment buildings. The apartment stock near the San Mateo Caltrain station carries master-key systems originally wired for 30-unit buildings that now service 80-plus units after interior conversions. High tenant turnover means constant rekeying demand, and old cylinders wear out faster under heavy key traffic. We do full master reconfigurations and cylinder replacements for these buildings on a scheduled basis.
- Failed smart-lock retrofits on unreinforced 50s and 60s door frames. Older San Mateo ranchers and bungalows frequently have door frames that were never prepared for a deadbolt at all, or were prepped with undersized screw holes. A smart lock installed on that frame is a lock waiting to be defeated. We install reinforcement plates and hardened strikes as the standard base for any smart or keypad lock on these homes.

FAQs - Lock Installation & Rekey in San Mateo
The marine layer that settles over San Mateo’s east side carries salt and sustained humidity, and it attacks the pin springs inside a lock cylinder first. The springs lose their temper, the pins bind, and the plug either won’t turn or turns with resistance until a key snaps. On a 1960s rancher in Beresford, we found the original Kwikset deadbolt seized solid from years of salt-laden air. The cylinder wouldn’t turn even with the right key. We got in without drilling, replaced the corroded cylinder with a marine-grade Schlage B560 deadbolt, rekeyed the knob to match, and upgraded the strike plate to ANSI Grade 1. The homeowner said it was the first time in years the deadbolt threw smoothly on the first turn. If your key sticks or your deadbolt feels gritty, call (331) 310-8471 before it fails completely.
For a 1950s rancher in Beresford or Fiesta Gardens, we recommend a Schlage B560 or B660 deadbolt with a hardened steel strike plate and 3″ screws into the stud. If you want keyless access, the Schlage Encode or Baldwin Evolved works well on the standard 2-1/8″ prep those homes came with. The key is reinforcing the frame and installing a deadbolt that can shrug off the marine layer, not just bolting a new lock onto a soft frame. We quote every option in writing before we start, and the hardware we install is the hardware on the invoice.
Yes, and we do it regularly. The 1960s apartment stock near the San Mateo Caltrain station is full of mortise locks that are no longer being manufactured, but we can rekey them, replace the cylinders, and rebuild the internals to keep them functional. In many cases, we can also convert a worn mortise lock to a modern cylindrical deadbolt if the door prep allows it. For master-key systems that have been extended through multiple interior conversions, we do full cylinder replacements and master reconfigurations on a schedule that works for the building. Call (331) 310-8471 for a written quote.
Most smart lock failures on older San Mateo doors come down to one thing: the door prep and frame were never reinforced before the lock was installed. A smart lock manufacturer assumes a solid door, a true 2-1/8″ cylindrical prep, and a frame that can take a 3″ hardened screw. Many 1950s and 1960s San Mateo homes have none of those. The lock gets installed anyway, the deadbolt binds against the misaligned strike, the motor strains, and the lock fails within months. We install smart locks the same way we install mechanical deadbolts: reinforce the frame, align the strike, and test the throw under load. That’s why our smart lock installations carry the 365-Day Done Right Promise. If it’s not done right, we make it right.
If the cylinder is seized from salt-air corrosion but the bolt and internal mechanism are still functional, we can often disassemble the lock, replace the pin-and-tumbler cylinder, and rekey it to your existing key, which is faster and less expensive than a full lock replacement. That runs $45 to $90 for the cylinder replacement and rekey, plus the service call. If the bolt itself is corroded or the strike is pitted, you’re better off replacing the whole deadbolt, which we’ll recommend straight rather than patching a failing lock. Call (331) 310-8471 and we’ll give you a firm number either way.
