Why Dunmore Locksmith Is Sausalito’s Preferred Change Door Locks Company
Dunmore Locksmith has worked on homes along Bridgeway, the floating communities at Waldo Point Harbor, and the hillside streets above Caledonia for many years. Perry Osgood leads our team, and every technician who arrives in Sausalito is background-checked, identity-verified, and sent to you by name and photo before the visit. That is the Threshold Standard, and it matters here because many Sausalito homes sit on steep, narrow lanes where you want to know exactly who is walking up your steps before you open the door.
Our technicians show a photo ID badge at the door and wear clean, marked uniforms. The price is put in writing before any work starts, and that written price is the price on the invoice. No call-out surcharge added on arrival, no after-the-fact totals. And every job is covered by the 365-Day Done Right Promise: if a lock we change fails within a year, we return at no charge. That guarantee is stamped in writing on every job we do in Sausalito.
Lock Change in Sausalito
Lock Change in Sausalito means removing the existing lock hardware from a door and installing a new lockset, deadbolt, or handle set. Most Sausalito homeowners arrange this after a move, a tenant turnover, a lost key, or a break-in on the block. A standard residential lock change here runs $95 to $180 per lockset, and a deadbolt replacement typically lands between $110 and $240 depending on the hardware grade and finish you choose.
When Rekeying Makes More Sense
If the lock itself still works and the door is square, we will often tell you to rekey instead. Rekeying changes the internal pins so old keys stop working, and it costs $65 to $120 per cylinder in Sausalito. You keep the hardware, and the old key becomes useless. That is the honest call, and we make it every time it applies.
When Replacement Is the Right Call
On older Sausalito doors where the cylinder has corroded from salt fog or the bolt no longer throws cleanly, replacement is the smarter move. Forcing a new keyway into a worn mortise lock or a rusted deadbolt on a floating home often fails within months. We will tell you directly which option we would take on our own door, and why.
Change Lock Cylinder in Sausalito
Change Lock Cylinder in Sausalito means swapping just the cylinder inside the lock, not the whole lockset. This is the fastest way to invalidate old keys while keeping the existing hardware, and it runs $70 to $140 per cylinder in this market. Homeowners on steep hillside lots above Bridgeway frequently choose this route because it preserves original Craftsman hardware that would be expensive or impossible to match today.
Cylinder Grades That Survive Richardson Bay
Salt air off Richardson Bay eats cheap cylinders. On a standard inland home, a zinc cylinder might last years. On a Sausalito door that faces the water or catches the morning fog, that same cylinder can seize inside eighteen months. For floating homes and bay-exposed hillsides, we stock 316 stainless and solid brass cylinders with satin nickel or marine bronze finishes. They cost more up front, and they are worth it.
Obsolete Cylinders and Mortise Locks
Many 1920s through 1950s cottages above Bridgeway still carry their original mortise locksets with skeleton-key cylinders. You cannot pick up a replacement at a big-box store. The cylinder format has been out of production for decades in some cases. We keep a working stock of compatible cylinders and have rekeyed hundreds of these locks without cutting into the original door.
Trusted Brands We Service in Sausalito
We are factory-authorized to install and service Schlage, Kwikset, Medeco, and Abloy hardware, along with Baldwin, Yale, Mul-T-Lock, and Sargent. Most Change Door Locks jobs in Sausalito involve Schlage or Kwikset deadbolts on residential doors, but when a homeowner wants a high-security cylinder, Medeco and Abloy are the standards we recommend. We keep marine-rated finishes and common Sausalito-specific parts on our service trucks, so we rarely need a second trip for parts.
Common Change Door Locks Problems We See in Sausalito Homes
- Salt-fog corrosion on bay-exposed lock cylinders. Homes facing Richardson Bay or sitting low near the water get a constant film of marine salt. Standard zinc cylinders start sticking within a season, and deadbolt bolts show surface rust even with regular use.
- Swollen original door frames on pre-1950 hillside cottages. Decades of marine humidity warp solid wood doors. A new deadbolt will not sit flush if the frame has moved, so we correct strike plate alignment before installing anything.
- Grade 2 “weatherproof” deadbolts failing on floating homes. The structures at Waldo Point Harbor and along Gate 5 Road move with the tide. Standard hardware flexes, the bolt binds, and within one winter the cylinder is shot. Marine-grade 316 stainless or solid brass is the only reliable spec here.
- Skeleton-key mortise locks on original Bridgeway-era homes. These locks are nearly a century old on some hillside cottages. They can almost always be rekeyed and restored, but a modern pin-and-tumbler deadbolt will not drop into the existing mortise pocket without cutting the door.

FAQs About Change Door Locks in Sausalito
Yes, in most cases you can change just the cylinder and keep the existing deadbolt body, provided the bolt itself still throws cleanly. The replacement cylinder needs to be marine-grade, specifically 316 stainless or solid brass with a satin nickel or marine bronze finish, because standard zinc cylinders will seize the same way within another season or two. We carry these cylinders on our trucks. Call (910) 714-4287 and we will give you an exact price for your deadbolt before anyone comes out.
Almost always it can be rekeyed, and we recommend that over replacement unless the lock body itself is cracked or the bolt is worn beyond repair. The cylinder formats on these pre-war mortise locks are out of production, but we keep compatible replacement cylinders and can rekey the lock to new keys while preserving your original hardware. Full replacement usually means cutting new holes in an original solid wood door, which we try hard to avoid. Expect rekeying with a cylinder swap to run $130 to $210 per lock.
On Sausalito doors, sticking is usually the frame, not the lock. Salt fog causes wood to swell and shift, especially on older hillside homes where the door has been absorbing marine humidity for decades. The cylinder turns, but the bolt binds against the strike plate because the door has moved. Lubricating the cylinder will not fix it. You need the strike plate realigned and sometimes the bolt replaced with a marine-spec part. We diagnose that on site, show you the exact problem, and quote the fix in writing before touching the door.
We stock it on our trucks. Dunmore Locksmith keeps 316 stainless and solid brass cylinders, satin nickel and marine bronze deadbolts, and corrosion-resistant strike plates in inventory specifically for the floating communities at Waldo Point Harbor and Gate 5 Road. You will not wait days for a special order, and you will not pay a surprise upcharge for marine-grade hardware. The price is quoted up front, in writing.
Yes, in many cases we can. The issue is whether the existing door has a standard 2-1/8 inch cross-bore or an original mortise pocket. On a standard pre-drilled door, a Schlage or Kwikset smart deadbolt drops in with no modification. On an original mortise door, we usually recommend either keeping the mortise lock and adding a surface-mounted keypad deadbolt above it, or converting to a modern lock with a faceplate that covers the old mortise cut. The honest answer depends on your door, which we will inspect in person and quote before any cutting happens.
