Rekeying locks is the most common service we perform in Tamalpais Valley, and it typically costs $95 to $175 for a standard single-cylinder deadbolt rekey, including labor. Homes here were largely built between the 1950s and 1970s, and many still have their original exterior hardware, which the valley’s salt fog and canyon moisture have not been kind to. If you just moved into a place off Eucalyptus or Sycamore and do not know who else has a key, call Citadel Locksmith at (833) 589-8078 and we will get your locks changed over the same day.
Why Tamalpais Valley Homes Are Different
Tamalpais Valley sits in a fog belt between Mill Valley and the Marin Headlands, and that changes what we find on the door. Marine fog and salt air roll through year-round, and on north-facing and canyon-side doors the condensation settles directly onto locksets, hinges, and gate hardware. Builders put cheap entry-grade deadbolts into these houses in the 1960s, and we routinely find them seized solid on homes a mile inland would have no trouble with. The housing stock is mostly wood-frame, redwood-sided, or stucco bungalows from the 1950s through the 1970s, with a number of newer hillside rebuilds mixed in. Many original doors and locksets are still in place. Driveway gates and side-yard fences are common here because of the canyon-slope lots, so padlock and gate-lock work comes up more than it does in the flatter towns east of 101. Winter rain swells the wood doors, deadbolts stick, and latch plates no longer line up. The second-home and rental key-control angle is also strong in Tamalpais Valley; we rekey a lot of properties between tenants or after a sale closes on a canyon road property. Citadel Locksmith has served Tamalpais Valley since 2011, and we carry hardware and parts selected for the corrosion realities of this specific valley, not generic parts that will fail in three winters.
Styles & brands we work with
Our Main Tamalpais Valley Services
There are two services Tamalpais Valley homeowners and drivers call Citadel Locksmith for most often: car key replacement and emergency locksmith response. Both have their own pages for this area, and each covers the specific conditions you deal with here, from fog-corroded house locks to car keys lost near the Headlands trailheads.
Car Key Replacement in Tamalpais Valley
Lost car keys turn into a bigger problem in Tamalpais Valley than in a flat city grid. Many residents park on inclined driveways off narrow canyon roads, and a tow to a dealership is slow and expensive. We replace transponder keys, key fobs, and traditional metal keys for most makes, often on the same call, and we do it without the dealership markup. For transponder programming and key cutting for your vehicle in the 94941 zip, see Car Key Replacement in Tamalpais Valley.
Emergency Locksmith in Tamalpais Valley
Foggy nights and canyon-side doors make lockouts feel more isolating in Tamalpais Valley than anywhere else in Marin. We answer emergency calls when you are standing outside a redwood-sided house on Sylvan Lane with a deadbolt that will not turn. Our emergency service covers lockouts, broken keys, and locks that have seized from moisture. If you are locked out right now, start with Emergency Locksmith in Tamalpais Valley for the fastest next step.

Rekey Locks in Tamalpais Valley
Rekeying in Tamalpais Valley is the fastest way to take back control of who holds a key to your home, and it solves the fog-corrosion problem without replacing every lock. When you buy a 1960s wood-frame house on a canyon slope, you have no way of knowing how many copies of the front-door key are floating around Marin. When you rekey, we change the internal pins so the old keys stop working and a new key operates the same lock. This is the standard move after a sale closes, after a tenant moves out, or after a breakup. We rekey Schlage, Kwikset, and Medeco cylinders regularly, and we stock the pin kits to do it on site. Tamalpais Valley’s salt air corrodes the exterior of a lock but leaves the internal cylinder workable in most cases, so rekeying gets you security without the higher cost of full hardware replacement. See Rekey Locks for the full scope of what we handle.
Lock Rekey
Signs you need it
You have just closed on a home in Tamalpais Valley, lost a key, or ended a relationship with someone who had a copy, and you do not want to replace perfectly good hardware just to change access.
What it costs in Tamalpais Valley
Standard lock rekey runs $95 to $175 per lock in Tamalpais Valley, including the labor and new keys.
How we do it
We remove the cylinder, swap the internal pins to match a new key, reassemble it, and test the lock in front of you before we leave.
Rekey Door Lock
Signs you need it
Your deadbolt still works but the key feels gritty or stiff from salt-fog corrosion, and you want to reset access on one exterior door rather than replace the whole assembly.
What it costs in Tamalpais Valley
Rekeying a single door lock typically costs $95 to $175 in Tamalpais Valley, with no markup for working on older 1960s hardware.
How we do it
We pull the lock cylinder, clean any corrosion out of the plug, install new pins matched to a fresh key, and then lubricate and reset the deadbolt throw.
What Rekey Locks Costs in Tamalpais Valley
| Item | Typical range in Tamalpais Valley |
|---|---|
| Single-cylinder deadbolt rekey | $95 – $175 per lock |
| Door knob or lever rekey | $95 – $175 per lock |
| Keyed-alike rekey (multiple locks to one key) | $85 – $145 per lock |
How does salt air in Tamalpais Valley affect rekeying?
Salt air corrodes the exterior hardware and can make the cylinder hard to remove. We carry penetrating lubricant and extraction tools for this exact condition, and most original cylinders from the 1950s and 1960s can still be rekeyed. If yours is too far gone, we will tell you and quote a replacement on the spot.
What is the difference between rekeying and replacing a lock in Tamalpais Valley?
Rekeying changes the internal pins so old keys stop working, while replacement swaps the entire lock assembly. Rekeying costs $95 to $175 in Tamalpais Valley and suits most homes here. We recommend replacement only when the exterior hardware has failed from fog corrosion or the lock body is damaged. Call (833) 589-8078 for a free estimate either way.

What Tamalpais Valley Customers Say
"Told me over the phone that what I needed was a five dollar part from the hardware store, not a locksmith. I called him back a month later for real work because of that."
— Yolanda Mendoza"Key snapped off in the deadbolt. He extracted it without damaging the cylinder, which I did not think was going to be possible."
— Oscar Reyes"The old deadbolt was mounted crooked by whoever lived here before and had been sticking for years. He redrilled and reset it properly rather than just replacing the hardware."
— Brandon Wong
