Does Nimbio work with a DoorKing gate or call box?

Yes. DoorKing (DKS) is on Nimbio’s supported list, and it doesn’t matter which part of your gate is DoorKing. Nimbio wires in parallel to the dry-contact trigger input on the gate operator, the same input your clickers, keypads, and call box already close to open the gate. If the operator is powered (6.5V–24V AC or DC), Nimbio works with it, and no operator replacement is required.

DoorKing gate operator

Nimbio connects to the operator’s trigger input and draws power from its existing supply.

A trigger input: the dry-contact terminals your clickers and keypads already use
Power: 6.5V–24V AC or DC from the operator’s existing supply
Nothing else: no Wi-Fi, no router, no Ethernet run

DoorKing call box with another brand’s operator

A DoorKing call box paired with another brand’s gate operator is a common setup. Nimbio wires to that operator’s trigger input alongside the call box, so the DoorKing call box stays in place and keeps working. Any operator on the supported list qualifies.

Nimbio’s technical support team supplies wiring diagrams for DoorKing (DKS) hardware and walks your installer through the connection by phone. Not sure your setup qualifies? Call 1-800-353-3422 before you install and support will confirm compatibility.

What changes once Nimbio is on your DoorKing gate or call box?

The gate itself stays the same. What changes is how people open it and how you manage who can.

Open from your phone or your car

Open the gate straight from the Nimbio app on iOS and Android, or from the dashboard with Apple CarPlay and Android Auto. No clicker to lose, no fob to replace.

Share keys, revoke them instantly

Family Keys give everyone in the household their own digital key on their own phone. From the Community Manager portal, a manager revokes any key holder’s or vendor’s key instantly, and can set a scheduled expiration date so access ends when you choose.

Know who came through

Nimbio can send a push notification every time a shared key is used — turn on key notifications for that key in the app. You can also check the gate’s live status, open or closed, from the app at any time.

Visitors without a camera at the gate

GuestView adds visitor video verification through the visitor’s own smartphone: they scan a QR code or tap an NFC panel, you get a text with a link, and a video call starts. GuestLinks let you share a link that opens the gate for a party or a one-off visit, with no app for the guest.

How is Nimbio installed with a DoorKing gate or call box?

Because Nimbio wires in parallel with your existing controls, installation is straightforward for a gate or low-voltage tech. Provisioning is done over Bluetooth in about 60 seconds.

Mount and power

Mount the Nimbio controller inside the DoorKing operator enclosure and connect power from the operator’s existing supply, any source from 6.5V to 24V, AC or DC.

Wire the relay in parallel

Wire the relay’s dry contact to the operator’s trigger input, in parallel with the existing clicker and keypad wiring. Nothing is removed. Set the adjustable Relay On Time (0.5s–10s) to match what the operator needs to actuate.

Power on and provision

The device connects to the strongest available LTE tower with no Wi-Fi setup. Provision the unit from the app over Bluetooth in about 60 seconds, then test the relay from the smartphone app.

Who does the install?

Physical installation is completed by independent, professional gate technicians or local low-voltage installers, and installation pricing is set directly by your selected technician. Nimbio’s technical support team is available by phone to give your installer step-by-step wiring walkthroughs during the install. We recommend a professional installer; HOA, multifamily, and commercial properties should confirm the work complies with local regulations governing gate access.

Can I keep my DoorKing call box, keypad, and clickers?

Yes. Nimbio runs in parallel with your existing access hardware. Every clicker, fob, keypad, and call box you already have continues to work exactly as before, including a DoorKing call box that opens another brand’s operator. Nimbio adds smartphone access, GuestView, and cloud management on top.

DoorKing compatibility questions

Does it matter whether my DoorKing hardware is the gate operator or the call box? +

No. Nimbio always wires to the gate operator’s dry-contact trigger input, in parallel with whatever already opens the gate. A DoorKing operator qualifies if it has that input and a 6.5V–24V AC or DC supply. A DoorKing call box on another brand’s operator qualifies if that operator does. Nimbio’s support team confirms wiring compatibility for your specific setup before you install: call 1-800-353-3422.

Does Nimbio need Wi-Fi or a wired network at the gate? +

No. Nimbio’s cellular controller connects directly to AT&T, Verizon, and T-Mobile. There is no Wi-Fi to configure, no router to maintain, and no Ethernet run to install. An internet outage at the property has no effect on the gate.

Do I need a new call box or a camera at the gate? +

No. Your existing DoorKing call box stays in place and keeps working. For visitor video, GuestView works through the visitor’s own smartphone camera, so no camera hardware needs to be mounted at the gate.

How much does it cost to add Nimbio to a DoorKing gate or call box? +

The Nimbio controller is $299. Service is flat-rate per home for residential communities, and flexible pricing based on active users for commercial properties. Installation is priced by the technician you choose. See the pricing page for details.

What happens if the gate loses power? +

If the DoorKing operator itself loses power, Nimbio, like the operator, won’t function unless a battery backup is installed for the gate motor. Solar-powered operators are fully compatible as long as the battery and panel keep the operator within 6.5V–24V.
