Ridgeline Lock & Key · Walnut Creek, CA
A Walnut Creek locksmith who names the whole number first.
From the Rossmoor gates at one end of town to the Shadelands business park at the other, a mobile van handles lockouts, rekeys, car keys and storefront hardware. You hear one figure on the call, it already contains the visit, the labor and the parts, and it is the figure that goes on the card when the work is finished.
Calls answered 24/7. The $89 service call sits inside the number you are given, never on top of it.

How it works
From the call to a door that locks
- 01
Call and describe the door
House, car, suite or safe, and where in the valley it stands. The whole number is settled on that call, before anything is agreed.
- 02
A text arrives before the van
The technician's name and a thirty-minute arrival window come through by text, so nobody has to guess who is knocking.
- 03
Ownership first, then the lock
The technician confirms the address or the vehicle is yours, then opens it without damage. Drilling comes up only if clean entry fails, and only with your word.
- 04
Card at the door, receipt in your inbox
Tap or card when the work is finished, itemized receipt by email, and a written description of the work if you need to forward it.

Price list
Printed ranges. One figure on the call.
Every job is quoted from the list below. The $89 service call is already inside the number you are given, and so is any evening or overnight rate — nothing is added after.

“My hands are not what they were and the old knob on the front door had become a wrestling match. Quoted $248 for a lever handle and an easy-turn deadbolt that meet the manor hardware standard, and $248 is what my card showed. He knew the gate check-in procedure and allowed for it instead of calling me from the entrance in a panic. Both keys work with one finger now.”
“Pulled the door shut behind me with the keys on the hall table, mid-morning, no spare anywhere. The number on the call was $135 and I was told a name and a half-hour window by text about a minute later. He was there inside twenty, had the deadbolt open in a few minutes without a scratch on a lock that has been in that door since the fifties, and the receipt was in my email before I had made coffee.”
“Our building manager flagged the rear exit device during a walk-through and we needed it sorted before the next inspection. $610 for a new rim device with an outside pull, fitted on a Wednesday afternoon while the office kept working. The receipt lists the device by brand and model, which is exactly what our facilities file needed. No surprises between the quote and the invoice.”
“Cash-counted, alarm set, and the back door cylinder seized with my keys and my jacket still inside at about nine at night. The call gave me $185, which was $145 for a commercial door and $40 for the evening, and that was the end of the arithmetic. Van arrived in around fifteen minutes, he checked my lease on my phone, and the door opened without drilling. Rekeyed the cylinder the next morning as a separate ticket.”
“We finally stopped wondering how many old house keys were out there after a remodel. Six cylinders rekeyed at $29 apiece, front, back, side gate, garage entry and two others, all keyed alike so we carry one key. The figure on the receipt matched the call exactly. Four stars only because arrival landed at the very back of the window and I had rearranged a morning around it. Work itself was tidy and quick.”
“Lost the only key to my wife's SUV somewhere between Heather Farm and the grocery. I assumed a tow and a dealer appointment. Instead he met us in the driveway, looked at the registration and my license, cut and programmed a key plus a spare, and we were done in under an hour. $295, the number I had been given on the call, nothing tacked on for the second key being a second key.”
Why Ridgeline
The part people brace for is the bill. That is the part we settle first.
One figure, named first
The visit, the labor and the parts are all inside the number settled on the call, and that number is what the card sees.
A van in the valley, not a counter
Mobile only. The van works between downtown, Ygnacio Valley and the hill streets rather than waiting for you to drive to a shop.
Hardware this town actually uses
Easy-turn deadbolts and lever sets for Rossmoor, mortise parts for the ranch houses, hookbolts and closers for Broadway Plaza glass, exit devices for Shadelands, and blanks for most cars in the BART garage.
Paper for whoever asks
An itemized receipt by email, parts named by brand and model, and a written line describing the work when the HOA or the insurer wants one.

Coverage
Every neighborhood in town, and the valley either side
The town is compact, so most addresses are about 18 minutes away. Rossmoor takes longer because of the gate. Each area page shows its own time.
Free estimate
Four questions, then the range from the rate card.
Not an emergency? Answer four questions and see the published range for your job in Oakland before you talk to anyone. If it is urgent, the form steps aside and hands you the number.
- 1What went wrong?A lockout, a key, a lock change, or something else entirely.
- 2Where is the door?A house, an apartment, a car or a business.
- 3How soon?If it is right now, the form gets out of the way and you call.
- 4Where does the range go?A name and a number. Email and cross street only if you like.
Before you call anyone
Five things worth asking before anyone drives out
A search for a locksmith in the valley turns up national call centers that advertise a low starting figure and invoice several hundred once the door is open. Each of these takes under a minute and applies to any company, including this one.
- 01Ask for one complete figure, with the service call and any evening difference inside it. An opening bid followed by "and up" is not a quote, it is an invitation to renegotiate on your doorstep.
- 02Ask who is coming and get the name in writing before dispatch. A company that will not put a technician's name in a text has not decided yet which subcontractor is closest.
- 03Ask what happens if the lock cannot be picked. The answer should describe a conversation with you before any drill comes out, not a shrug about how these things go.
- 04Read the name on the invoice. It should match the business you searched for and carry a 925 number, not a generic heading with no city on it.
- 05Decline cash-only. An itemized card receipt is the thing an HOA, a property manager or an insurer will actually accept later, and a figure written on a pad is not a record of anything.
FAQ
Asked before the call, answered here
How quickly does the van reach my part of Walnut Creek?+
The citywide average is 18 minutes. Downtown and Broadway Plaza usually see the van in about 12, Walnut Heights in 14, Parkmead in 15, Saranap and Ygnacio Valley in 16, Northgate in 18 and Shadelands in 20. Rossmoor runs closer to 24 because the gate check-in is the longest of any address in town, and the streets above Castle Rock Rd take longer again for the climb and the driveways. Alamo is around 20, Pleasant Hill 16, Lafayette 18, Concord 20 and Danville 22. A slow stretch on I-680 or Ygnacio Valley Rd shows up in the window you are given, which is set from the traffic at that moment rather than from an average.
What is The Whole-Number Promise?+
It means the figure you are given on the call is complete. The $89 service call, the labor, the hardware fitted and any evening or overnight difference are all inside it, stated once as a single number. That number is what the card is charged. It moves only if you ask for something additional while the technician is there, such as rekeying a second door after a lockout, and that addition is named and agreed as its own line before the work on it begins.
Do evenings, weekends and holidays cost more?+
Weekends and holidays are charged at the same daytime figures. Arrivals between 8pm and midnight add $40 and arrivals between midnight and 7am add $75, and both are folded into the number before you agree to anything. So a $120 house lockout is $160 in the evening and $195 overnight, and the receipt shows that same total with nothing appended at the door.
How does a visit to Rossmoor work?+
Give the manor or co-op address and the entry you use, and the van goes through the gate check-in like any other visitor, which is why Rossmoor is quoted at about 24 minutes instead of the citywide 18. Daytime visits are preferred and easiest for everyone. The van carries lever handles, easy-turn thumbturns and low-effort deadbolts that suit hands that have had enough of stiff hardware and that sit within the community's hardware standards. If the mutual or the HOA needs paperwork, the emailed receipt names the hardware fitted and describes the work in a line you can forward.
Will my lock have to be drilled?+
Almost never, and never as a first move. Deadbolts, lever sets, apartment cylinders, storefront hookbolts, most safes and most car doors open with picks, decoders, bypass tools and air wedges, and the hardware still works when the door is open. If a cylinder is broken, seized or high-security enough that clean entry fails, the technician explains what drilling would mean and what replacing the cylinder costs before touching it, and the figure stays where it was set on the call. If we cannot get you in at all, nothing is charged.
What do I need to show before a door or a car is opened?+
For a house or condo, photo ID with that address, or ID plus a lease, a utility bill or mail on your phone when the ID address is older than the move. For a car, ID plus the registration or an insurance card, digital is fine. For a suite, shop or office, ID plus a lease, a business license, or confirmation from the owner or the property manager. It takes a minute and it is the reason the work is worth anything.
Can the original hardware in a 1950s Walnut Heights or Parkmead house be kept?+
Usually, yes. Mid-century knob sets, mortise bodies and screen-door latches can be rekeyed, cleaned, re-sprung and adjusted on site, and worn springs and cylinders are often replaceable from the van. When a case is cracked or the parts have simply stopped existing, a modern body can be fitted into the original door cut so the trim, plates and door itself stay untouched. Which of those makes sense is discussed at the door, with the figure agreed before anything is unscrewed.
How are master key systems and access control priced for a Shadelands or Ygnacio Valley building?+
Both are quoted in writing after someone has walked the doors, because a suite with four doors and a building with forty are not the same job and no published range would tell you the truth about either. The walk-through covers the door count, the existing cylinders, who needs to open what, and whether readers and fobs make more sense than keys for the tenants who turn over. You get an itemized quote with a per-door breakdown, and that quote is what gets invoiced. Weekend and after-hours work in an empty building is arranged in advance at the same figures.
