Compustar CS920-S 1‑Way Remote Start & Keyless Entry — 1500 ft Range, 2 Remotes, Diesel‑Safe

The Compustar CS920-S (920S) is a 1-way remote start and keyless entry bundle that gives you up to 1,500 feet of control with two 4-button remotes and a CM900 control module.

The CS920-S combines simple operation and broad compatibility to bring reliable remote start, door locking/unlocking and trunk release to most automatic vehicles. Designed as an all-in-one package, this system is diesel-engine safe and includes two 1-way LED remotes so you can start your car, secure it, or pop the trunk from a distance. Professional installation is recommended because some vehicle makes and models need additional harnesses or modules not included in the kit.

How far will the remote reach and what affects that range?

The advertised maximum range is approximately 1,500 feet under ideal, line-of-sight conditions. Actual range depends on surroundings, building materials, nearby radio frequency noise and the vehicle's installation location. Metal structures, dense urban environments or interference from other electronics can reduce effective distance.

• Maximum theoretical range: up to 1,500 ft in open areas
• Common real-world range: typically less in cities or parking garages
• Interference sources: large metal objects, other RF devices, thick walls
• Installation placement: antenna height and module location influence signal

What controls and functions do the remotes provide?

Each package includes two four-button 1-way LED remotes that operate remote start, lock, unlock and trunk pop functions. The remotes send commands to the CM900 control module; because these are 1-way remotes, they transmit commands but do not show confirmation back on the remote. Visual LED feedback on the remotes helps confirm button presses at the device itself.

• Buttons: start, lock, unlock, trunk pop
• LED indicators: confirm remote button press visually
• 1-way operation: remote transmits commands only
• Two remotes included: convenient for a second driver or valet

Will this work with my vehicle and what does installation involve?

The CS920-S is compatible with many automatic transmission vehicles, but vehicle-specific wiring or accessory modules may be necessary. Diesel-safe circuitry is included for compatible diesel engines, and the kit features a long-lasting battery in each remote. Because wiring varies by make and model, professional installation is strongly recommended to ensure safe integration with factory systems, alarm features and immobilizers.

• Compatibility: automatic transmissions only; check vehicle fitment
• Diesel-safe: built to support diesel engine remote starting where applicable
• Possible extra parts: some vehicles need additional harnesses or bypass modules (sold separately)
• Recommended: professional installer for proper integration and safety
