An Emerald Hills Gate, a Long Driveway and a Locked House at the End of It

The gate is the first lock, the driveway is the second problem and the house has nine doors. Why the arrival to Emerald Hills is twenty-seven minutes and how that is said honestly, how a gate release works when the power is off, what the van needs from a steep drive, and what a whole-property visit costs.

An Emerald Hills Gate, a Long Driveway and a Locked House at the End of It

Why twenty-seven minutes, and why it is honest

Across Redwood City the average arrival is twenty-one minutes. Emerald Hills is twenty-seven, and the six extra are geography rather than caution. From Farm Hill Blvd or Jefferson Ave the roads climb and wind, the lanes narrow, and the last stretch to most houses is private. There is no straight line to anything on this hill. The estimate given on the call is built from where the van is and which road it will take, and if the honest number that evening is thirty-four, thirty-four is what is said.

The figure does not change with the estimate. A house lockout is $119 to $205 on the hill as it is on the flat, with $50 added between 8pm and midnight and $85 after midnight, and the $89 service call inside the total. What the hill changes is what happens between the van and the door, which is the rest of this article.

The gate is the first lock

Most driveways in Emerald Hills begin with a gate. Swing gates on two posts, slide gates on a track, on a keypad at the pillar, a remote in the car and sometimes a phone app. All of them run on an operator with a motor and a battery backup, and all of them have a manual release for the day the motor or the battery fails. The release is behind a small cylinder on the operator housing, or on a lever inside a locked box on the post. That cylinder is a lock like any other. It can be opened, it can be rekeyed at $25 to $41, and it should be on a key the household can find.

The gate decides the shape of the visit. If it is open, the van comes up. If it is closed and you are inside with the remote, you meet the van at the gate. If it is closed and the power is off and nobody can find the release key, the technician opens the release first and the house second, inside the same figure. Say on the call which of the three it is, and say whether the gate is a swing or a slide, since the release differs.

What the van needs from the driveway

A driveway on this hill can be two hundred feet of gravel at a grade the van was not built for, with a turnaround at the top that fits a sedan. The technician makes a judgment at the gate: drive up if there is room to turn, or park at the gate and carry the case. Neither costs you anything and neither changes the figure. What helps is knowing in advance. Say how far the house is from the gate, whether the drive is paved, and whether there is room to turn a van at the top.

Cell reception between the redwoods is patchy, and that shapes the texting. The technician's name and the thirty-minute window are sent before the van leaves the flat part of the city, while the signal is good. The technician calls from the gate rather than from the road. If your house has one bar, give a landline or a second number on the call.

The house with nine doors

Hillside houses sprawl. A front door that visitors use, a mudroom door the family uses, French doors onto the deck, a door from the garage, a side door on the detached garage, a pool house, a garden shed, and two side gates. Nine cylinders is an ordinary count, and the first thing settled on a rekey call is that count, because it is the figure. A whole-property rekey after a purchase is $25 to $41 per cylinder, and the result is one key for the buildings and one for the gates, or one key for everything if you prefer.

Some of those doors will not take a rekey. A cylinder that turns with a similar key, a knob whose plug is worn oval, a French door latch from a maker that stopped making them in 1985: those are replacements at $115 to $309 per door, and the technician says which ones at the door. Safes come with these houses more often than not, in a closet or under the stairs, with the combination gone; opening one is $179 to $505 and the door usually survives.

Codes for the housekeeper, the gardener and the pool service

A house with a long driveway has people coming up it who do not live there. The gate keypad has a code for each of them, or should, and the same is true of the door they use. Smart locks at $175 to $449 installed put a code on the mudroom door for the housekeeper and another for the pool service, retired in a minute when the service changes. The gate keypad gets the same treatment: one code per company, and the codes from two gardeners ago deleted.

Two cautions. A smart lock on a door that swells in the wet months will report a locked door that the bolt never reached; the technician checks that the door closes without a shove before anything goes on it. And the override cylinder on the smart lock is a lock, keyed to whatever the installer had in the van; it goes on the rekey list with the rest.

County land, the figure and the window

Emerald Hills is unincorporated. That means the road belongs to the county, the sheriff rather than the city police answers a call about a prowler, and a permit for a new gate comes from a different office. It changes nothing about a locksmith visit except that the address is sometimes recorded under a different town name; give the street and the cross street, and the van will find it.

Sequoia Lock & Key works to a promise called Settled Before the Key. The figure is settled on the call, covering the visit, the labor and the parts, with the cylinder count in it when there is one. The technician's name and a thirty-minute window arrive by text before the van leaves. The door is opened without damage first, and drilling happens only after you agree, at the same figure. Payment is card or tap at the door, with an itemized receipt by email and a written line for an insurer if a safe or a forced door is involved. On the hill, the promise includes an honest number of minutes.

Quick answers

The power is off and the gate will not open. Can the technician still get to the house?+

Yes. Every gate operator has a manual release behind a small cylinder or in a locked box on the post. The technician opens the release first and the house second, inside the same figure. Say on the call whether the gate swings or slides.

How is a whole-property rekey priced on a house with many doors?+

By the cylinder, at $25 to $41 each, with the count taken on the call so that one figure covers the lot. Garage side doors, the pool house, the shed and the gate release are all cylinders. Doors too worn to repin are replaced at $115 to $309 and named at the door.

Why is the arrival to Emerald Hills longer than the rest of the city?+

The roads wind, the lanes are private, and there is no straight line up from Farm Hill Blvd. Twenty-seven minutes is the average and the estimate on the call is built from that evening's route. The figure does not change with the wait.
