Most locksmith calls in Sunnyvale come down to three things: a key that stopped working, a lock that no longer fits the door frame, or a lock that still works but you’re not sure who else has a key. Rekeying solves that last one – we change the internal pins so old keys stop working, without replacing the hardware. In Sunnyvale, with its 1950s Eichler homes, 1970s apartment buildings, and newer condos near Lawrence Station, that usually means working on original mortise locks, builder-grade Kwikset, or worn Schlage deadbolts. Call (877) 265-4385 and you’ll get a direct answer, not a sales script.
Why Sunnyvale Homes Are Different
Sunnyvale’s housing stock spans three distinct eras, and each brings its own lock problems. The Eichler and Eichler-style tract homes built in the 1950s and 1960s – concentrated in 94086 and 94087 – often still carry their original mortise locks and single-cylinder deadbolts. The door stiles on those homes are narrower than modern standards, so replacing a mortise assembly isn’t a simple swap; it usually means retrofitting an ANSI Grade 1 lock into a door that wasn’t built for it. That’s a job many neighboring-city locksmiths rarely see.
The apartment complexes from the 1970s and 1980s – scattered around El Camino Real, Wolfe Road, and the areas near Sunnyvale Town Center – were fitted with builder-grade Kwikset and Weiser hardware. Those cylinders wear predictably, and we see a steady stream of rekey requests from landlords between tenants. The newer high-density condos near downtown and Lawrence Station have more modern hardware, but the climate still plays a role: summer heat and dry air cause exterior locks to stiffen and doors to shift slightly, throwing deadbolts out of alignment. Winter rains swell the older wood-frame doors, which makes a misaligned deadbolt suddenly impossible to throw. None of this is dramatic, but it’s why a lock that worked fine in June might bind in January.
Styles & brands we work with







Our Main Sunnyvale Services
Beyond rekeying, the two calls we take most often in Sunnyvale are car key problems and lockouts. Here’s what each involves in this city.
Car Key Replacement in Sunnyvale
Sunnyvale’s tech-heavy workforce means a lot of late nights at the office and a lot of car keys lost in parking garages or left on desks. We cut and program replacement keys for most makes, including transponder keys and fobs, without sending you to a dealership. The work happens where the car is – whether that’s a driveway in 94087 or a lot near Moffett Park. Car Key Replacement in Sunnyvale covers the details, key types, and what we need from you.

Emergency Locksmith in Sunnyvale
Locked out at the wrong hour – we’ve handled it before, and we’ll handle yours. Tenant lockouts are especially common in Sunnyvale’s rental-heavy market, and landlords often call us to coordinate access when a resident is locked out of an apartment unit. Emergency Locksmith in Sunnyvale explains response expectations, what to have ready, and how we handle different types of lockouts without damaging your door.

Rekey Locks in Sunnyvale
Rekeying is the smartest security move in Sunnyvale, where so many homes and apartments have changed hands – or changed tenants – without changing the locks. When you rekey, we replace the internal pins inside the existing lock cylinder so the old keys stop working and a new key operates the lock. No new hardware, no major cost. Property managers running empty units in 94085 and 94089 do this routinely between leases; homeowners do it after a roommate moves out or a contractor returns the keys. Rekey Locks is something we recommend proactively, not just reactively.
Lock Rekey
Signs you need it
You moved in and have no idea how many spare keys are floating around from the previous owner, previous tenants, or the contractor who remodeled the kitchen.
What it costs in Sunnyvale
A standard door lock rekey in Sunnyvale – one cylinder, our key blanks, labor – is typically $40 to $85 total.
How we do it
We remove the cylinder, swap the internal pins to match a new key code, and test the lock with the new key before reinstalling – no new hardware needed.
Rekey Door Lock
Signs you need it
The lock still works fine mechanically, but there’s a new person in the household, a departing roommate, or a recent break-in attempt and you want to invalidate every old key.
What it costs in Sunnyvale
Our rekey cost is built as a flat service call plus per-cylinder labor, which lands around $75 to $160 for a full entry door with deadbolt done in one visit.
How we do it
We rekey the handle and deadbolt to the same key so both work on one key, then hand you the new keys and test the cylinder through a full turn.
Keyed Alike
Signs you need it
Your front door, back door, and garage side door each have their own key and you’d prefer one key for all of them.
What it costs in Sunnyvale
Keyed alike – matching multiple cylinders to a single key – adds about $15 to $25 per additional cylinder after the first.
How we do it
We repin each cylinder to the same key code and label the new keys so you know exactly which one opens every door on your property.
What Rekey Locks Costs in Sunnyvale
| Item | Typical range in Sunnyvale |
|---|---|
| Service call (arrive + first lock) | $40 – $85 |
| Per additional lock cylinder (same visit) | $15 – $25 |
| Keyed alike – match extra cylinders to one key | $15 – $25 per cylinder |
Can you rekey a lock without replacing it in Sunnyvale?
Yes. We rekey the existing cylinder, which means the housing stays in your door and the lock is reconfigured to a new key. It’s faster and more affordable than full replacement, and it’s exactly what most Sunnyvale apartments and Eichler homes need between tenants.
How long does a rekey take in Sunnyvale?
Most standard rekey jobs in Sunnyvale take 15 to 30 minutes once we’re at the door. Multi-lock properties or keyed-alike requests take longer. Call (877) 265-4385 and we’ll give you a realistic window before anyone is dispatched.

Pricing for Locksmith in Sunnyvale, CA
| Service | Typical range in Sunnyvale |
|---|---|
| Rekey a lock (flat service call + first cylinder) | $40 – $85 |
| Per additional cylinder (same visit) | $15 – $25 |
| Keyed alike (match multiple locks to one key) | $15 – $25 per cylinder |
| Full entry door rekey (handle + deadbolt) | $75 – $160 |

What pushes a Sunnyvale job toward the higher end is usually the key type – smart fobs and transponder keys cost more to program – or a door that’s been previously replaced or repaired and now fights the hardware. Heat-warped doors, common on the older wood-frame homes after summer, can add a few minutes of realignment that a newer door wouldn’t need. Whatever the number, you’ll get the full price quoted on the phone before anyone is dispatched, and that’s the price on the invoice – no call-out surcharge added on arrival.

What Sunnyvale Customers Say
"Quoted a price on the phone and honored it. After the last locksmith I called, that alone is worth a review."
— Sarah Vaughn"Got me back in and the price was fair for the hour. He did arrive closer to 45 minutes than the 20 he estimated, which felt long standing outside, but he was honest that traffic was the problem."
— Marcus Prince"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."
— Lisa Sullivan
