DoorKing access control installation in Los Angeles typically runs $450 – $900 installed for a keypad, card reader, or telephone entry system replacement, with most jobs finished in a single visit because we stock the common DoorKing boards, keypads, and power supplies on our trucks. The part number on your existing unit tells us almost everything we need before we arrive. Most LA owners call us after the keypad stops reading codes, or a card reader goes dead overnight, or the gate simply stops responding to the call button on the phone entry box.
We’re Calder Gate Repair Los Angeles, part of the Relay Home Co. family since 2009. We’re an independent service provider, not affiliated with DoorKing, but we carry the genuine DoorKing components and know the compatibility traps that bite people who buy parts online and hope for the best. Give us the model number and we’ll tell you exactly what fits and what it costs.
Key Takeaways
- Most DoorKing access control installs in Los Angeles run $450 – $900 installed, written price agreed before we start

Which DoorKing Models This Applies To
DoorKing splits its access control line into three families that share surprisingly few parts between them. The 1812 series is the apartment and condo telephone entry box you see at call boxes across Los Angeles, from Echo Park walk-ups to Toluca Lake gated complexes. The 1830 series is the heavy-duty commercial telephone entry system with directory scrolling and larger display panels, common in parking garages and mixed-use buildings. Then there’s the MicroCLICK or MicroPLUS family, the compact RF and keypad systems used on single-family gates from Sherman Oaks to Pasadena.
The compatibility gotcha most people hit: the 1812 keypad and the MicroCLICK keypad look nearly identical but use different ribbon connections, and swapping one for the other will fry the board or simply do nothing. Always check the label inside the enclosure for the exact model and revision, usually printed on a white sticker above the main board. When the label is sun-baked or missing (very common after a decade in California heat), we identify the unit by wiring pattern and board silk-screening instead.
For DoorKing specifically, we recommend genuine OEM parts on anything involving the main logic board or power supply. The aftermarket keypads are fine for basic code entry, but we’ve seen too many generic power supplies drift to 13.8V under load, which causes intermittent keypad lockups on the 1812 series. DoorKing boards are picky about voltage, and this is one place where saving $40 on a generic part creates a recurring mystery problem. We stock OEM boards, keypads, RF receivers, and power supplies for the 1812, 1830, and MicroCLICK lines, plus quality aftermarket keypads when the budget matters.
Styles & brands we work with





Signs Your DoorKing Access Control Installation Is Failing
- Keypad lights up but won’t accept codes. The keypad membrane is worn out or the code storage chip on the main board has failed. In coastal Los Angeles, salt air accelerates this failure on exposed keypads within five to seven years.
- Gate opens randomly, or won’t close after a code entry. The RF receiver is picking up stray signals from a nearby transmitter, or the loop detector input is getting noise from a failing ground. We trace this with a signal meter rather than guessing.
- Telephone entry box rings but audio is garbled, or no audio at all. The phone line transformer or the audio amplifier board has failed. On 1812 units, the audio board is a separate plug-in module, which makes this a fast, clean swap.
- Display shows scrambled characters or nothing at all. The power supply is sagging under load or the display board is on its way out. We check the DC output first because a dying power supply can take the main board with it if ignored.
- Gate works from the remote but not from the keypad or card reader. The access control relay output has failed, or the wiring between the access control unit and the gate operator board has a broken connection. This is the most common failure we see in Los Angeles where fences shift with temperature swings and pull on junction boxes.

AfterReplacement Cost & What’s Included
Access control replacement on a DoorKing system in Los Angeles typically runs:
- Keypad or card reader replacement: $450 – $650 installed
- Main board replacement (1812 or MicroCLICK): $550 – $800 installed
- Telephone entry motherboard (1830 series): $650 – $900 installed
- Power supply replacement: $350 – $500 installed
- Complete keypad + board + RF receiver overhaul: $800 – $1,200 installed
The range depends on which DoorKing generation you have, whether we’re replacing one component or a cluster, and whether your existing wiring needs cleanup. Los Angeles gate enclosures often collect corrosion from irrigation overspray or coastal air, and we factor in any re-termination work honestly before we start.
Every access control installation includes a written price before any work starts, the part, labor, wiring cleanup, and programming of your existing codes and entry settings. The 365-Day Done Right Promise covers the whole job: if it fails within a year, we return at no charge. The number on your invoice is the number we agreed to at the door.
DIY or Call Us?
There are a few things worth checking before you call us. Confirm the keypad is getting power by looking for a lit display or a faint beep when buttons are pressed. Check whether the gate operator itself works from the remote, because a dead remote battery plus a “broken keypad” is sometimes just a power supply that feeds both. And check your breaker box: a tripped GFCI is the cheapest DoorKing fix in Los Angeles.
Beyond that, these systems deserve a professional. The main boards are static-sensitive, the 1812 and 1830 units carry live 16V AC power on exposed terminals inside the enclosure, and miswiring a keypad ribbon can destroy a board that would have cost $150 to swap but now costs $600 to replace. If the idea of metering a transformer or re-terminating low-voltage commons doesn’t sound like your Saturday, call us at (213) 322-1415 and we’ll get a tech out with the right part on the truck.
FAQs
A DoorKing access control installation typically lasts 8 to 12 years in Los Angeles, with keypads wearing out first on units exposed to direct sun and power supplies failing most often in areas with frequent irrigation or coastal salt exposure. Systems in shaded, dry enclosures go longer. Call (213) 322-1415 if your unit is at or past that window and we’ll assess what needs attention.
Keypads and card readers are rarely repairable, but main boards can sometimes be saved with a component-level fix, and we always check for repairable power supply issues before quoting a full board replacement. If a repair is safe and will hold, we’ll tell you that first. Estimate is free either way.
A keypad or card reader swap typically takes 60 to 90 minutes, while a full 1812 or 1830 telephone entry board replacement takes two to three hours including reprogramming your codes and directory. We bring the common parts on the truck, so most Los Angeles jobs finish in one visit. Call (213) 322-1415 for a same-day appointment.
We stock the common DoorKing keypads, RF receivers, power supplies, and 1812/1830 boards on our trucks, and we source OEM parts for less common revisions the same day from local suppliers in Los Angeles. You never need to buy the part yourself, but if you already have one, we’ll install it and stand behind the work with the same 365-Day Done Right Promise.
