DoorKing Keypad & Intercom Repair Nationwide

DoorKing Keypad & Intercom Repair: The Miami Beach Owner’s Guide

We stock and install DoorKing-compatible keypad and intercom repairs in Miami Beach, with most keypad swaps running $280-$420 installed and intercom module repairs at $340-$580 depending on whether the 1812 series board or the 1833 series surface-mount unit is involved. Same-day service is available when the part is already on the truck, which it usually is for the 1802, 1803, 1808, and 1812 series units we see most often along Collins Avenue and Alton Road. Most Miami Beach owners discover the failure when the keypad still lights up but won’t release the gate, or when the intercom rings through to the house but the door strike doesn’t trigger - the classic split between power and logic.

Which DoorKing Models This Applies To

DoorKing has manufactured access hardware since 1948, and the product lines stack deep. We regularly service four series in Miami Beach: the 1802 stand-alone keypad (residential, 1-25 codes), the 1803 multi-code version, the 1808 vandal-resistant stainless unit, and the 1812 intercom entry system with its 1833 surface-mount or 1834 flush-mount call station. The 1812 series also has a 1812-080 variant that handles eight lines instead of two - a detail that matters because the main board part number changes.

To identify your unit, check the label inside the keypad housing or on the intercom base plate. The model number is stamped, not printed, and often faded in Miami Beach properties where the housing seal has hardened from UV exposure. If the label is gone, measure the faceplate: the 1802 is roughly 3.5 inches wide, the 1808 is closer to 5 inches with a thicker bezel, and the 1812 intercom module is a distinct rectangular box separate from the call button assembly.

We carry both OEM DoorKing parts and quality aftermarket equivalents where they exist. For the 1802 and 1803, aftermarket keypads from Linear or Elite sometimes fit the mounting pattern but use different wire color coding - we document the pinout mismatch before installation so the next technician isn’t decoding our work. For the 1812 intercom, we prefer OEM boards because the audio impedance matching is finicky; we’ve seen aftermarket modules produce feedback loops in the humid Miami Beach air that OEM boards don’t.

Signs Your DoorKing Keypad & Intercom Repair Is Failing

• Keypad lights up, gate doesn’t move. The backlight and button beep draw low current from the transformer, but the relay that triggers the gate operator has burned contacts or a cracked solder joint on the board. In Miami Beach, we see this more often on west-facing gates where afternoon heat cycles the relay hundreds of times daily.
• Intercom rings inside, door strike won’t release. The call path and the strike circuit run on separate outputs from the 1812 control board. When one fails and the other works, the board is usually the culprit - not the wiring, not the strike itself.
• Intermittent code acceptance. You enter the code three times; it works on the third. This is early membrane switch failure in the keypad, moisture intrusion under the overlay, or corrosion on the ribbon cable connector. Salt air from the beach accelerates all three.
• Garbled or one-way audio on intercom calls. The 1812 uses a two-wire audio path that degrades when the transformer voltage drifts below 16VAC. We check the transformer first, then the board’s audio amplifier section - but in Miami Beach, we’ve found corroded terminal blocks causing voltage drop before either component actually fails.
• Keypad completely dark, no beep, no response. Usually power - but not always the transformer. The 1802 series has an internal fuse that blows when moisture bridges the terminal strip. We test for this before quoting a full keypad replacement, and we photograph the terminal condition under Clause 4 so you see why.

Replacement Cost & What’s Included

The price we write is the price you pay. Before any work starts, we hand you a written scope with the part number, labor line, and total - Haven Standard Clause 1. That price includes removal, installation, programming of up to five codes or intercom numbers, and testing of the release circuit. Under our 365-Day Done Right Promise, if the keypad or intercom fails for any reason related to our installation, we return and make it right at no charge. Every visit leaves a documented photo record: what we found, what we set, what we installed. Name what you found, name what it costs, name what you left behind.

DIY or Call Us?

There is one safe check a homeowner can make: verify the transformer output with a multimeter set to AC volts. The 1802 and 1812 both want 16-24VAC; if you’re reading 12 or zero, the problem is upstream. Beyond that, we recommend against DIY on these units. The 1812 intercom board handles low-voltage logic and line-level audio on the same terminal strip - reverse a pair and you can send 24VAC into a phone line or fry the audio section. The 1808 keypad’s stainless housing has a grounding scheme that matters for surge protection; we’ve replaced units where the ground was omitted and a nearby lightning strike took out the gate operator too.

We carry the common DoorKing parts on the truck specifically because a second trip wastes your morning and ours. If you’re in Miami Beach and the keypad or intercom is acting up, call (786) 371-2767. We’ll ask for the model number, the symptom, and whether you’ve checked the transformer. If we don’t have the part, we’ll tell you before we dispatch - no surprise, no bait-and-switch.
