The Keystone Heddolf P219-1KA is a compact, single-button keychain remote transmitter designed to operate compatible gate operators and garage door openers. Operating at 318 MHz, it serves as a dependable replacement remote for many legacy Allstar, Allister, and Pulsar fixed-code systems used in residential and light commercial applications. Its pocket-friendly design makes daily access convenient, while the one-button interface delivers straightforward open/close control for doors, gates, and barrier arms that use matching 318 MHz fixed-code receivers.
Programming the P219-1KA is done by setting the internal trinary DIP switches to match the code configuration in your existing receiver or a working remote—no special tools or software are required. This model is intended for fixed-code 318 MHz systems and will not work with rolling-code platforms (for example, Linear MegaCode, Security+, or Intellicode). For best results, confirm your opener/receiver’s frequency and code type before purchase and only operate a moving door or gate when it is in clear view. The P219-1KA is an ideal replacement or upgrade keychain remote for compatible Allstar/Allister/Pulsar 318 MHz dip-switch installations.
