The Keystone Heddolf P220-2KB is a two-button remote transmitter for gate and garage door openers, designed as a replacement controller for fixed-code systems. It allows you to operate two separate operators or channels from a single handheld remote, making it a practical upgrade for residential or light commercial applications where multiple doors, gates, or receivers need control. Buyers commonly use the P220-2KB as a replacement remote for legacy fixed-code radio controls found in many Allstar/Allister/Pulsar installations.
This model is commonly associated with fixed-code, dip-switch style radio controls operating at 318 MHz under the Allstar/Allister/Pulsar family. Setup typically involves opening the remote and matching the internal code switches to those on your existing remote or receiver, then testing range and operation at the doorway or gate. Because this is a fixed-code transmitter, it is not compatible with rolling-code or proprietary encrypted systems (e.g., Security+, Security+ 2.0, Intellicode, Homelink rolling code, etc.). Always confirm your receiver’s frequency and code type on its label or manual before purchase to ensure compatibility. The P220-2KB is suited for replacement and expansion use cases where a dependable, two-channel, dip-switch programmed remote is required.
