The Keystone Heddolf P220-1KB is a compact, one-button keychain remote designed for operating compatible gate operators and garage door openers. Ideal as a replacement or spare transmitter, it provides simple, reliable control of your access system in residential or light commercial applications. The P220-1KB belongs to the P220 series from Keystone Heddolf, a line known for brand-specific compatibility, so the “-1KB” variant is intended to match systems that use its corresponding radio format and receiver type.
Setup typically involves programming the transmitter directly to your opener or external receiver—either by using the learn/program button on the operator or by matching the receiver’s switch settings, depending on the technology used by your system. For best results, confirm compatibility by matching the P220-1KB designation with the frequency/protocol noted on your existing remote or receiver label and by consulting your opener’s manual or the Keystone Heddolf compatibility chart. As with any access control device, keep remotes out of reach of children, program and test the unit within receiver range, and verify that safety reversing features on the door or gate function correctly after programming.
