CompuStar 900R 1-Way Remote

The CompuStar 900R is a 1-way, 4-button remote transmitter designed for Compustar remote start and security systems. It provides effortless control for vehicle owners who need a replacement or additional handset. The unit works with compatible control modules and antennas listed in the specifications.

Range and Signal Headroom

The transmitter covers distances of 1000 to 1500 feet, giving reliable signal transmission across typical parking lots or driveways. Performance drops beyond the 1500-foot maximum, so users in larger campuses or dense urban canyons may find the range insufficient. Dual AM and AP frequency support adds flexibility when matching the system antenna.

Build and Daily Use

The remote is not water-resistant, so it should be kept away from rain, spills or humid environments. Its four-button layout handles arm, disarm, remote start and auxiliary functions without menus. Compatibility is limited to CM-900X, CM2305-A, CM2500, CM900-AS, CM900-S control modules and ANT-1WAM or ANT-AP antennas.

Questions about this item

Will the 900R remote work with my existing CM2305-A control module?

Yes, the 900R is compatible with the CM2305-A module as well as the CM-900X, CM2500, CM900-AS and CM900-S modules.

How can I verify the 900R is communicating with the system after pairing?

Press any of the four buttons; the vehicle should respond with the expected remote start, lock, unlock or trunk release action confirming the link.

Does the 900R package include an antenna or do I need to buy one separately?

An antenna is not included; you must purchase a compatible ANT-1WAM or ANT-AP antenna separately for the remote to function.
