Rekeying a lock in Belvedere is a different job than anywhere else in Marin. The island’s custom-built estates, salt-air exposure, and narrow access roads mean standard hardware often isn’t standard at all. We routinely rekey Baldwin mortise locks on 1920s waterfront homes, service Mul-T-Lock cylinders on gated hillside properties, and match keyways across multi-door estates where the previous owner never kept records. If you need a locksmith in Belvedere, call Cypress Lock & Key at (877) 265-4385.
Why Belvedere Homes Are Different
Belvedere sits in Richardson Bay as a small island connected to Tiburon by two roads, and that geography shapes every locksmith job here. The marine fog and salt air accelerate corrosion on exterior lock cylinders, deadbolts, and gate hardware, especially on bay-facing doors along Belvedere Avenue and West Shore Road. We regularly find seized Schlage cylinders and rusted strike plates that inland Marin properties never experience. Housing stock ranges from original early-1900s estates with thick wooden doors and vintage mortise sets to recent architectural builds with multi-point locking systems and custom iron gates. Many properties are second residences, which means locks sit unused for months, and the first unlock attempt after a long vacancy often reveals a frozen mechanism. Narrow, hillside lots mean some doors are only reachable by stairs, and driveway gates need their own keyed systems. This is not a market where a basic Kwikset rekey covers the job. Most Belvedere homes demand premium hardware, matched keyways, and a technician who understands both the mechanics and the key-control needs of a high-value property.
Styles & brands we work with







Our Main Belvedere Services
Two services Belvedere homeowners call about most often are car key replacement and emergency lockout response. Each has its own page with full details, but here’s what they look like on the island.
Car Key Replacement in Belvedere
Losing a car key in Belvedere is particularly inconvenient because leaving the island means crossing the Tiburon drawbridge and navigating mainland traffic just to reach a dealership. We cut and program replacement keys on-site in Belvedere, covering most makes without the dealership wait. Salt air affects car locks too, and we often handle fobs or keys that have degraded from Bay exposure. For complete details on coverage and cost, see our Car Key Replacement in Belvedere page.

Emergency Locksmith in Belvedere
Locked out of a Belvedere home at night, the access route actually works in your favor: low traffic means a technician can reach you quickly once across the bridge. We carry tools for antique mortise locks, modern smart deadbolts, and gate hardware on every call. If you need an Emergency Locksmith in Belvedere, the page covers response expectations, what we can open without damage, and typical after-hours pricing.

Rekey Locks in Belvedere
Rekeying in Belvedere means changing the internal pins of your existing locks so old keys stop working and new keys operate them. The hardware stays in place, but access changes completely. We do a lot of rekeys here for estate purchases, staff turnover, and homes where a previous owner never accounted for every key that was handed out. Because so many Belvedere properties use premium brands like Baldwin and Mul-T-Lock, rekeying often costs more than a standard Kwikset job but still costs far less than replacing the hardware. That’s the core of our Rekey Locks service, adapted to Belvedere’s housing stock and salt-air conditions.
Lock Rekey
Signs you need it
You bought a Belvedere home and don’t know how many copies of the old key are floating around with prior owners, contractors, or caretakers.
What it costs in Belvedere
A standard single-cylinder deadbolt rekey in Belvedere typically ranges from $65 to $120 per lock, with premium hardware like Baldwin or Mul-T-Lock running higher.
How we do it
We remove the cylinder, replace the internal pins to match a new key, reassemble the lock, and test every key before we leave the property.
Keyed Alike
