The Keystone Heddolf EX220-1KB Long Range Remote is a one-button handheld transmitter designed to provide extended reach for automatic gate operators and garage door openers. Ideal as a replacement remote or an add-on for multi-user sites, it delivers dependable control for residential and light commercial applications where extra operating distance is important, such as long driveways, gated communities, or parking access points. The EX220-1KB is part of Heddolf’s aftermarket lineup, engineered to work with a compatible receiver matched to the correct frequency and code type, giving installers and end users a straightforward path to upgrading range without changing the entire operator.
Use involves pairing the transmitter to the existing system’s receiver, typically through a learn/program button on the receiver or, on some legacy systems, by matching switch settings; always follow the operator or receiver’s manual for exact steps. For compatibility, confirm the model designation, frequency, and code format required by your gate or garage system and ensure a matching Heddolf or universal receiver is in place if the original operator’s radio is not supported. As with any access control device, observe UL 325 and local safety guidelines, keep transmitters out of reach of children, and test the operator’s safety sensors after programming. This long-range Heddolf remote is a practical choice for users searching for a reliable upgrade or replacement transmitter for gate opener and garage door applications where strong, consistent RF performance is needed.
