Martinez locksmith service: houses on the hill above the strait, shops on Main Street, lockers at the marina

Twenty-three minutes is the citywide average, measured from Todos Santos Plaza. Downtown and the plaza run about 16 minutes, the Monument corridor 18, Sun Terrace and Meadow Homes 19, Bates Avenue and the yards 23, Ygnacio Valley 23, North Concord and Willow Pass 23, Dana Estates and Holbrook Heights 24, Clayton Valley and Crystyl Ranch 26. Outside the city line: Pacheco 19, Pleasant Hill 23, Walnut Creek 24, Martinez 28, Clayton 29. The hill streets and the far towns are honestly the slowest and you hear that on the call rather than standing on a porch wondering. The window that arrives by text is drawn from where the van actually is, not from the average.

Because of when this city was built. Concord went from 6,953 people in 1950 to 85,164 in 1970, and the houses went up in one push between 1955 and 1968, tract by tract, fitted with the same few locks. Two bore sizes, one backset, four finishes covers most of the housing stock, and a great deal of that hardware is still on the doors. Name the street and the door is largely known: what fits it, what the strike looks like, what usually fails on it. That is what turns a guess into a figure you can hear before anyone gets in the van.

Three things move a job inside its range. First, which tract the door came from, because a 1957 street and a 1967 street were not built with the same hardware. Second, what has been changed on it since: an added deadbolt, a replaced cylinder, a security screen, a slider bar, a strike somebody moved. Third, which hour you are calling in. Once you have said the street, the door and the time, the figure is a single number, not a range, and it stays that number on the receipt.

Almost never, and never without your agreement. Picks, decoders and bypass tools cover builder deadbolts across the tracts, apartment cylinders on Monument and Detroit, aluminum storefronts on Salvio and Grant, patio sliders, most car doors and most safes, and the lock goes back to work afterward. The exceptions are a high-security cylinder, one already smashed, or one welded around a snapped blade. When that is your door you hear it plainly, you hear what would replace it, and you choose. The figure does not move either way.

The $89 visit, the labor, whatever hardware goes on the door, and the night hour when there is one, all rolled into the number you hear. Steps up from the street in Holbrook Heights, a buzzer lobby on Monument Boulevard, a latched side gate in Crystyl Ranch, a gated yard off Port Chicago Highway: none of that moves it. The only thing that can add is extra work you decide on while the technician is standing there, such as putting the garage side door on the same key while the front is open. That gets a figure of its own, said out loud, and it starts when you say yes.

Saturday, Sunday and holidays cost what a Tuesday afternoon costs. Only the clock changes anything: $40 between 8pm and midnight, $75 between midnight and 7am. Both are folded in before you hear a figure, so nothing appears later. A house lockout that is $115 in daylight comes back as $155 at eleven at night and $190 at four in the morning, all of it inside the same published range, and the receipt matches what you agreed to.

No. This corridor has the largest share of renters in the city and a tenant is the customer, not a complication. For a lockout, bring photo ID showing the address, or ID plus something on your phone that ties you to the unit: a lease page, a utility bill, a rent receipt, addressed mail. Give the building and the unit number on the call, because a buzzer panel with forty buttons is no help to a van circling Detroit Avenue. Nobody is contacted about you, and no owner has to approve putting you back into the place you pay for.

Cylinders are counted per door at $25 to $40 each, and the whole property comes back as one figure that already holds the visit, not a visit charge with cylinders piled on top of it. A fourplex with front and back doors is eight cylinders and one number. Each unit can sit on its own key with a single management key over the set, so you carry one key instead of a ring. Old keys come back in labeled bags to check against whatever the outgoing tenant handed over, and the receipt lists every door by unit. A manager acting for an owner elsewhere can approve the work with a management agreement or a text from the owner.

Usually not. Streets through Sun Terrace, Meadow Homes and the Ygnacio Valley spine are full of builder knob sets and later deadbolts that still turn well and only need repinning so keys from three owners ago stop working. Three things genuinely earn replacing: a cylinder with real wear in it, a bolt whose throw no longer reaches the frame, and a strike screwed into trim instead of the stud behind, which is the single detail that decides whether a door survives a kick. Which of the three applies to yours gets said before anything is unscrewed.

Both. Man-doors beside roll-ups on Bates Avenue, warehouse offices off Solano Way and Port Chicago Highway, yard gates along the Port Chicago side, storefronts and restaurant back doors around the plaza on Salvio and Grant. Early starts are normal there, because a shop that cannot open at seven loses a shift rather than a morning. On the car side, a good share of the work sits in the Sun Valley Mall lots, the Concord and North Concord park-and-ride rows, the Diablo Valley College lots and the Willows. Name the lot and give a row, a level or the color of the car. A gated garage needs somebody who can get the van through the gate. None of it changes the figure.
