Fast, Reliable Gate Access Control Across Center Line
Gate access control in Center Line usually means retrofitting a modern keypad, intercom, or card reader onto a gate that was hung back when Eisenhower was in office. On most of the narrow lots in this 1.4-square-mile city, the issue isn’t the electronics. It’s the post, the hinges, or the sag that makes even a working keypad useless because the gate itself won’t swing clean. We fix all of it. Hal Gatewood has been at this since 2001, and the person who answers when you call (877) 610-2993 is a live person, any hour, any day.
Why Gatewood Fence & Gate Is Center Line’s Preferred Gate Access Control Company
We know Center Line. It’s a 1.4-square-mile enclave city completely surrounded by Warren, packed almost entirely with modest postwar single-family homes on very tight lots. That matters for gate access control because the work here isn’t what you’d see in Rochester Hills or Birmingham. Nobody is installing a 900-pound ornamental iron driveway gate on a 40-foot-wide Center Line lot. They’re trying to make a 60-year-old chain-link driveway gate open with a keypad instead of getting out of the car in February.
Hal Gatewood’s name is on the shop, the address is published, and he’s been at this since 2001. When you call, a live person answers, not a voicemail, not a call center three states away, not a chatbot. That matters when your gate won’t open at 7 a.m. and your car’s in the driveway. Every job carries the 90-Day Done Right Promise in writing. If it’s not done right, one call brings him back. No runaround.
Our Gate Access Control team includes background-checked, uniformed people who will show up when we say they’ll show up. We’re certified to service Linear, Viking, Ghost Controls, and DoorKing equipment, among others. We stock common parts for Center Line jobs, so we’re not waiting on a truck from Texas to fix your keypad.
Our Gate Access Control Services in Center Line
Keypad Entry
A keypad entry system in Center Line runs $350 to $900 installed when the gate and post are in decent shape. That includes the keypad itself, the wiring to the operator, and programming. On older gate operators with obsolete control boards, expect to add $250 to $500 for a new board or retrofit module. This is the single most common upgrade we do here, usually because a homeowner is tired of handing out a key to every family member and delivery driver.

Remote Control
Adding or replacing remote controls for your Center Line gate runs $85 to $220 per remote, depending on the brand and whether we need to pair it with an older receiver. Linear and Ghost Controls remotes are what we’re asked about most. If your old remote stopped working and it’s not the battery, the problem is often the receiver board on a 20-year-old operator, which we can usually replace in one visit.

Phone Entry
A phone entry intercom that calls your cell phone when someone presses the button at the gate runs $700 to $1,500 installed in Center Line. That includes the intercom unit, mounting, wiring to the gate operator, and programming the call-forwarding. On narrow Center Line lots where the gate is close to the house, we can often run the wiring in a single afternoon. You won’t have to walk outside to let in the grandkids.

Card Reader
Card readers for driveway gates in Center Line run $500 to $1,100 installed, including the reader and the control relay. They make sense when a lot of different people need access on a regular schedule. For most single-family homes on these tight lots, a keypad does the job, but if you have a shared driveway or a rental unit on the property, a card reader is the more practical answer. We’ll tell you which one makes sense for your gate after looking at it, not before.

Safety Photocells
Modern safety photocells are $120 to $350 installed and they’re not optional. UL 325 entrapment protection is federal safety law for any automated gate. A lot of Center Line gates were automated before the requirement existed, or the original photocell was damaged or removed. If your gate reverses for no reason, a misaligned or failing photocell is the first thing we check.

Trusted Brands We Service in Center Line
We’re certified to service nine major gate brands, and in Center Line we see a lot of Linear, Viking, Ghost Controls, and DoorKing equipment on gates that have been automated for a decade or more. We stock common Linear and DoorKing control boards and photocells locally, so a Center Line keypad repair doesn’t turn into a two-week wait. If your operator is from a brand we don’t service, we’ll tell you that on the phone, not after we’ve taken the cover off.
Common Gate Access Control Problems We See in Center Line Homes
- Frost-heaved hinge posts. Shallow original footings from the 1950s and 60s shift the swing gate arc enough that the safety photocell beam gets broken every time the wind moves the gate, tripping the operator into reverse. We see this on nearly every residential call in Center Line.
- Corroded loop detectors in cracked driveway concrete. Road salt and brine from Van Dyke Avenue and 8 Mile Road wear down the embedded loops over 50+ Michigan winters, so the gate won’t open for a car pulling up to the keypad. The loop thinks there’s no car there.
- Worn rack and pinion teeth on slide gate operators. When the gate frame sags even an inch from original, the motor fights the bind and burns out from constant overload. A new operator on a sagging gate is a waste of money.
- Obsolete control boards. A lot of Center Line gate operators were installed in the 1990s or early 2000s. The board fails, the keypad won’t talk to the motor anymore, and the gate just sits there. We can often retrofit a new board without replacing the whole operator.
Pricing for Gate Access Control in Center Line, MI
Here’s what gate access control actually costs in Center Line. A keypad entry retrofit runs $350 to $900. Phone entry intercoms run $700 to $1,500. Card readers run $500 to $1,100. Adding a safety photocell runs $120 to $350. If the gate itself needs sag correction, post resetting, or new hinges before the electronics will work, that’s separate and typically runs $200 to $600 depending on how far the post has moved.

FAQs - Gate Access Control in Center Line
The keypad is almost never the problem. On Center Line homes, the gate usually reverses because the safety photocell beam is being broken by the gate itself as it swings, since frost heave has moved the hinge post enough that the gate no longer travels the arc the photocell expects. Call (877) 610-2993 and we’ll reset the post and realign the photocell in one visit, then your new keypad will work the way it should.
Yes, solar gate openers work in Center Line, but on shaded narrow lots between two homes, the panel often won’t get enough direct sun to keep the battery full through a Michigan winter. We usually recommend running low-voltage wire from the house for reliability. That’s a $200 to $400 job on most Center Line properties, and it means your gate opens in February, not just in July.
We look for two things: how far out of plumb the post has heaved and whether the concrete footing is cracked. On a 60-year-old Center Line gate with a shallow original footing, the post is usually out by an inch or two, and the footing is failing. In that case, we reset the post in a new concrete footing, which costs $300 to $600, and it’s cheaper in the long run than mounting a new keypad and operator on a post that keeps moving. If the post is solid and plumb, we’ll reuse it and save you the money.
That’s usually a failed control relay between the intercom and the gate operator, or the operator’s receiver board has died of old age. On Center Line jobs we test the relay first, because a new relay is $75 to $150, while a new control board is $250 to $500. We diagnose the actual failure before quoting anything, so you’re not paying to replace a board that’s fine.
Yes. We answer the phone 24 hours a day, 7 days a week, and we’ll give you a straight answer about when we can be there. Most Center Line gate access control repairs don’t require a full day, and we keep common Linear, DoorKing, Ghost Controls, and Viking parts in the truck. If your gate is stuck open, tell us when you call and we’ll make it a priority.
