About
Mortise bodies and exit devices ride in the same van.
One van off Davis Street since 2015, houses in the morning and shop floors after, any hour of any day. The lock comes open without damage wherever it allows, and what was said on the call is what the receipt shows.

Owner of the Davis Street van
I split my days the way this city splits: porches in Best Manor and the Manor tracts before noon, man-doors beside the Davis Street roll-ups after. Eighteen years of that, and since 2015 under the Estudillo name.
A shop owner on Doolittle and a renter off Bancroft get the same rule from me. Nothing gets drilled that could be picked, and every job on an Estudillo receipt is mine to answer for, ninety days on.
Same voice on the line since 2015
Estudillo Security has been answering San Leandro calls since 2015, and there has never been a counter to walk into. A lock is bolted to a door on Estudillo Avenue or hung on a man-door behind a Davis Street roll-up, and neither one is going to drive anywhere, so the bench rides in the van and the van comes to the address. The name is lifted off the map rather than invented: the Estudillo rancho became this town, the avenue still runs through it, and the Casa Peralta stands a block off it.
Some things get said plainly because people ask. Nobody here bought a franchise, nobody holds a dealership, no lock maker or car manufacturer has a say in what goes on your door, and your address is never sold on to whichever van bids for it. One 510 number rings this business, one dispatch answers it, and the technician who knocks is paid by the name at the top of your receipt. Byron Boykin leads the work and still runs calls; his 18 years between the marina and the hills started well before the sign went up.
Loaded for both halves of this city
San Leandro asks two different trades of one van before the day is out, so the shelves carry both at once. Mortise bodies, repinning stock and period strikes for the thirties and forties houses in Estudillo Estates, Best Manor and around the Broadmoor curves. Builder deadbolts, knob sets and levers for the Washington Manor and Floresta Gardens tracts. Electric strikes, deadlatches and entry panels for the buzzer flats off Bancroft and along Halcyon Drive. Hookbolts, cylinders and closers for the aluminum glass fronts on East 14th and Washington Avenue. Exit devices and jamb armor for the man-doors beside the roll-ups on Davis Street and Doolittle Drive. Keypad locks, safe tooling, and blanks with the programmers to match for most of what parks at Bayfair, in the two BART garages and out in the airport rows.
Hauling the house side and the shop side on one set of shelves costs weight, and it buys the line that matters on the invoice: one visit, one figure, no return trip. The alternative is a door taped shut until a part arrives and a second $89 visit somebody has to justify, which is a poor way to end a job that started at seven in the morning on a shop floor.
The Same Number Twice
Four things that hold the same way for a fourplex off Bancroft, a 1938 house on Estudillo Avenue and a warehouse man-door on Alvarado. Ninety days on the workmanship, whichever door it is.

The call, the window, the door, the receipt
Your figure is settled while you are still on the phone, written the way a shop writes a line on a sheet: what the thing is, how it is counted, what it costs. A house lockout is $119 to $205 per visit. A rekey is $26 to $42 per cylinder, so a front door, a back door, a side gate and a garage make four of them. Exit devices are $289 to $739 per door. The $89 visit sits inside that figure instead of waiting at the bottom of the invoice, and the clock is counted in the same breath: $45 on an arrival between 8pm and midnight, $80 between midnight and 7am. Master key systems and access control are the one thing not priced over a phone. Those get walked, counted door by door and put in writing, because a building nobody has looked at cannot be quoted honestly.
Then a text goes out carrying the technician name and a thirty-minute window drawn from where the van actually is, not from the 23-minute citywide average. At the address, ID is matched to the door or the registration to the plate before a case is opened. The lock is picked, decoded or bypassed and keeps working afterward; a drill only appears once you have heard what it does to the hardware and said yes, and saying yes does not move the number. A card or a phone tap at the door closes it, the itemized receipt lands in your inbox under a business name, and 90 days of workmanship coverage is printed on that same sheet.
Lines we take off the invoice, and work we turn away
Nine doors in ten that refuse a deadbolt have a frame problem rather than a lock problem: the door has settled a few millimeters on tired hinges and the bolt now catches the lip of the strike. Moving that strike and driving two long screws through to the stud is a short line on the invoice, not $115 to $299 of new hardware. A house still carrying keys from three owners ago wants one rekey at $26 to $42 a cylinder. A mortise case in Best Manor that has hung there since the thirties can be cleaned, re-sprung and repinned far more often than it deserves replacing, and the trim stays where the builder put it. A binding man-door on Davis Street is usually its hinges and its strike, not its cylinder.
Other work gets declined on the phone rather than at your curb. A short list of makes and model years locks key programming to a dealer tool, and hearing that up front is worth more to you than a trip charge is worth to us. Safes fitted with a relocker, high-security lines whose blanks are cut only against a registered owner card, and any job where the manufacturer is genuinely the cheaper road all get named for what they are. Every one of those is an invoice we do not write, which is exactly why it gets said out loud.

FAQ
Asked about the business behind the van
Is this one shop, or a service that takes the call and passes my address on?+
It is one business working one city. The 510 number on this site rings that business, the technician sent out is on its payroll, and nothing about your job is resold to a third van. It matters because a good share of the national listings sitting above the map results are booking operations: they take the call, keep a margin and hand the work down to whoever answers, and the gap between what you were told on the phone and what you are asked for at the door is where that margin lives. Here it is one figure, counted in one unit, said on the call and repeated on the receipt.
How long has Estudillo Security been working San Leandro doors?+
Since 2015, on the same two halves of the day the whole time: houses in the morning, shop floors after, lockouts whenever they land. Byron Boykin, who leads the work and still runs calls, has 18 years between the marina and the hills behind him. What the years actually buy on a service call is recognition — the settled frames in the fourplexes off Bancroft, the bit-key hardware still hanging on bedroom doors in Best Manor, the hookbolts that stopped throwing on East 14th, the man-doors on Davis Street that somebody once forced back into line with a bar. Most of that is named on the call instead of discovered at the door.
Is there a counter in town where I can hand over a lock?+
There is no counter and there is not going to be one. Rent, posted hours and a drive across town at the worst hour of your day all end up inside somebody's figure, and none of it puts a key in your hand any sooner. The van stages off Davis Street instead, which keeps the houses on one side of the tracks and the works on the other: about 15 minutes to Downtown, East 14th, Estudillo Estates and Best Manor, 26 up in Bay-O-Vista and out at Bayfair, 23 across the city on average. Key cutting, cylinder work, repinning and fob programming all happen at your curb, off the bench that rides on board.
How do I know the person knocking is yours?+
The text sent when the van pulls off Davis Street carries the technician name and a thirty-minute window. Holding that name against the person on your step takes a second and is the cheapest safety check this trade offers. Ask for the figure from the call to be repeated back before anything is opened, because that is the other half of the same check. If the name is wrong or the figure has grown, nothing has started yet: shut the door and call the number on this site again.
What if the cylinder in my door simply refuses to give?+
That gets said out loud before anything is put to the door. Apartment cylinders off Bancroft, post-war deadbolts in the Manor, mortise sets in Best Manor, aluminum storefronts on East 14th, most car doors and most safes come open intact and go back to work afterward. The exceptions are a high-security cylinder, one already smashed in a break-in, and one welded around a snapped blade. When that is your door, the technician stops, explains what a drill costs the hardware, names the part that would go back in its place and what it runs, then waits for your answer. The figure agreed on the call stands whichever way you decide.
