AfterLock Repair in San Francisco, CA
Lock repair in San Francisco usually means a latch that will not catch, a deadbolt that grinds, or a keypad that has stopped reading codes. A gate technician can typically fix or replace these components in under an hour, and most repairs run between $95 and $285 depending on the part. At Latch and Post Gate Repair San Francisco, we show you the written price before any work begins, and we answer the phone at (628) 227-2771 around the clock. If you have a sticking latch on an exterior gate in the Richmond or a corroded lock cylinder near Ocean Beach, our full Gate Repair service includes lock work as a core repair, not an afterthought.
We are part of the Cedarwell family of independently owned and operated gate specialists. Every gate comes down to two parts: the latch that holds it and the post that carries it. That is the job we focus on. For lock repair, that focus means we replace worn internal springs, align strike plates that have shifted with the fog-season ground movement, and swap out rusted cylinders on Ghost Controls and DoorKing hardware that homeowners in the Sunset and Noe Valley rely on daily.

When You Need Lock Repair
Lock problems do not usually announce themselves dramatically. You notice the gate feels looser than it did last month, or the key turns but the bolt does not fully seat. In San Francisco, the salty air near the Avenues and the near-constant moisture in Glen Park accelerate corrosion on lock internals faster than most homeowners expect. Here is what we hear from customers before they call us:
- The latch will not catch. The gate swings closed but bounces back open. This is often a strike plate that has drifted a quarter inch out of alignment, or a spring inside the latch body that has snapped. Common on gates that get heavy use in the Mission and Bernal Heights.
- The key turns hard or sticks. Salt and fog work their way into the cylinder, corroding the pins. We see this most on gates within a mile of Ocean Beach or the Embarcadero, where Mighty Mule and Elite locks take the brunt of the marine layer.
- Keypad reads codes intermittently. For gates with Ghost Controls or DoorKing keypads, moisture behind the faceplate can cause intermittent fault codes. The lock itself may be fine, but the access reader needs resealing or replacement.
- Deadbolt grinds but does not extend fully. The internal gears on electric deadbolts wear down over time, especially on gates that lock and unlock multiple times a day in multi-unit buildings in the Castro or Hayes Valley.
- You hear a metallic rattle when the gate closes. A loose lock body inside the gate frame sounds like a minor annoyance, but left alone it will wallow out the mounting holes and create a larger repair.
- Key snaps off in the cylinder. This is more common in San Francisco than people think, particularly when a homeowner forces a stiff lock on a cold, damp morning. We extract the broken key and replace the cylinder rather than replacing the entire lock assembly when possible.
If any of these sound familiar, Gate Repair in San Francisco starts with an honest assessment of what is worn and what still has life left. Call (628) 227-2771 and a live person will answer, day or night.
Our Lock Repair Process
Lock repair follows a careful sequence because the lock is only as good as the alignment around it. Here is how we work, on every visit, without exception:
- We listen and look before we touch. You describe the symptom. We inspect the entire gate, the post, the hinges, and the lock assembly. Ask before we move or touch anything, per the Cedarwell C.A.R.E. values.
- We write the price down. Before any work begins, you receive a written price. No pressure, no verbal estimate that changes later. If the repair requires a part we do not carry that day, we tell you the exact cost and the timeline before ordering.
- We protect the space around the gate. We lay drop cloths on the floor and put on shoe covers before we step inside. For homes with kids and pets, we choose pet-safe lubricants where there is a choice, and we can schedule around nap time if quiet matters.
- We repair or replace only what needs it. A worn spring gets replaced, not the whole latch body. A corroded cylinder gets rekeyed or swapped. Factory training on brands like DoorKing, Elite, Ghost Controls, and Mighty Mule means the right fix happens on the first visit.
- We test the lock through full cycles. We open, close, lock, and unlock the gate multiple times, listening for grinding, checking the throw of the deadbolt, and confirming the strike plate alignment is true. For keypads, we test the code entry three times minimum.
- We show you the cleanup before we leave. Shoes covers come off, drop cloths get folded, and we take a photo of the clean work area, just as we found it. You receive that photo. Then we walk you through what we did and what to watch for.
Every one of these steps falls under the 365-Day Done Right Promise. If the repair is not right, Latch and Post makes it right. No argument, no fine print.
Lock Repair Pricing in San Francisco
Lock repair in San Francisco typically ranges from $95 to $285 for most residential gate locks. Simple latch adjustments sit at the low end, while keypad replacement or electric deadbolt rebuilds run higher. Here is a breakdown of what we quote in neighborhoods like the Richmond, Noe Valley, Potrero Hill, and the Sunset:
- Latch alignment or strike plate adjustment: $95 to $140. A quick fix when the lock mechanism itself is still sound.
- Latch body or spring replacement: $120 to $190. Includes the cost of a new interior spring, spring-loaded latch, and testing.
- Cylinder replacement or rekey: $130 to $210. We replace the cylinder or rekey it to work with your existing key, on brands like Elite and Mighty Mule.
- Electric deadbolt rebuild (Ghost Controls, DoorKing): $180 to $285. Includes gear replacement, motor testing, and resealing against moisture.
- Keypad replacement or reseal: $150 to $260. For access systems that work with Ghost Controls or DoorKing openers.
- Broken key extraction plus cylinder replacement: $160 to $240. We extract the broken key fragment, replace the cylinder, and cut or rekey as needed.
What affects the final number? The brand of lock, the age of the gate, the condition of the post, and whether the moisture damage extends beyond the lock itself. A gate post that has shifted due to San Francisco’s clay-heavy soils in areas like Twin Peaks or Diamond Heights will require more than a lock adjustment; the post may need gate realignment or to be reset first. That is exactly why we inspect the full gate, not just the lock.
You will see the exact number in writing before we touch anything. Estimates are free, and there is no obligation to proceed. Call (628) 227-2771 for a straight answer.
FAQs – Lock Repair
How much does lock repair cost in San Francisco?
Most residential lock repairs in San Francisco cost between $95 and $285, depending on whether we are adjusting a latch, replacing a cylinder, or rebuilding an electric deadbolt. The written price is provided before work starts, so there is never a surprise. Call (628) 227-2771 for an exact quote, free of charge.
Can you fix a gate lock the same day?
Yes, in most cases. Because our technicians carry common parts for brands like DoorKing, Elite, Ghost Controls, and Mighty Mule, we can often complete a lock repair or automatic gate repair in one visit. For less common electric locks, we may need one to two business days for a part to arrive. Call (628) 227-2771 and we will give you a realistic timeline upfront.
Is it cheaper to repair or replace a gate lock?
Repair is almost always cheaper when the lock body is intact, since a full replacement typically costs $200 to $400 or more with labor. We only recommend replacement when the housing is cracked, the internal gears are stripped, or the corrosion has spread too far to make a reliable repair. You will see both options in writing and decide with no pressure.
Do you service keypad entry locks on gates?
Yes. We service keypad and key entry systems on gates from Ghost Controls, DoorKing, Elite, and Mighty Mule. Moisture behind the keypad faceplate is the most common cause of intermittent failures in San Francisco, and we reseal or replace the unit, then test the code entry multiple times before we leave.
What if the lock repair fails after you leave?
That falls under the 365-Day Done Right Promise: if the repair is not right, Latch and Post makes it right, no argument, no fine print. Call (628) 227-2771 and a live person will answer, any hour, any day.
Why San Francisco Homeowners Call Latch and Post for Lock Repair
The fog, the salt air, and the shifting soil are not abstract concerns here. They are daily conditions. We work on gates in the Sunset, where weld and rust repair is needed early and often. We work in the Mission, where gates see constant use and latches fail from fatigue, not age. We work in Noe Valley and Glen Park, where steep grades put unusual load on posts and locks. In each case, the repair starts with what is actually wrong, not a script. Cody Beckman has led our team since we started serving San Francisco under the Cedarwell banner in 2009, and the approach has not wavered: tell the truth, protect the home, fix it right the first time.
If your gate lock has gone from stubborn to unreliable, call us. A live person answers at (628) 227-2771, and we will walk through what you are seeing before we even schedule the visit. Free estimates, written pricing, shoe covers and drop cloths on every visit, and a cleanup photo before we leave. That is how lock repair should work in San Francisco.
