Two 1-Way 4-Button Remotes Included
The CS920-S includes two Compustar 900R 1-way remotes.
Each remote uses a simple 4-button layout designed for common functions such as:
- Lock
- Unlock
- Remote start
- Auxiliary functions
Having two remotes is useful for households with multiple drivers or simply as a backup if one transmitter is lost.
There’s no LCD screen to crack.
No charging cable to keep track of.
No daily menu system to navigate.
Just buttons.
Sometimes buttons are underrated.
Remote Engine Start
When professionally installed in a compatible vehicle, the CS920-S allows you to start the engine remotely before entering the car.
That gives the vehicle’s climate-control system time to begin:
- Heating the cabin
- Cooling the interior
- Defrosting windows
- Clearing morning frost
Remote start is particularly useful during extreme summer and winter weather.
Instead of sitting in the car waiting for the HVAC system to catch up, you can let the vehicle begin warming or cooling before you leave.
If you’re learning what actually goes into adding remote start to a vehicle, our guide on how to convert a car to remote start explains why remote starters need proper ignition, brake, hood-safety and immobilizer integration.
Keyless Entry
The CS920-S can also control compatible factory power door locks.
When properly integrated, the included remotes can provide:
- Lock
- Unlock
- Remote start
from the same transmitter.
That makes the system particularly useful on older vehicles where the factory remote is lost, damaged or has very limited range.
Trunk Release Output
The system also provides an auxiliary output that can be configured for functions such as remote trunk release when the vehicle supports it and the installer connects the appropriate circuit.
Additional relay hardware may be necessary depending on the vehicle.
Not every trunk-release circuit can be operated directly from the control module.
CM900-S Remote Start Control Module
The heart of the CS920-S is the Compustar CM900-S.
This current Compustar control module is designed specifically for remote start and keyless-entry applications.
It supports:
- Remote engine start
- Keyless-entry integration
- Multiple Compustar RF remote platforms
- DroneMobile expansion
- BLADE-AL bypass integration
- ADS-AL CA bypass/interface integration
The CM900-S is an automatic-transmission-only controller.
Automatic Transmission Only
This is an important compatibility requirement.
The CS920-S should be used with automatic-transmission vehicles.
The CM900-S does not support Compustar’s manual-transmission remote-start reservation sequence.
If you’re shopping for a manual-transmission vehicle, choose a Compustar controller specifically designed to support manual-transmission remote start.
BLADE-AL Ready
The CM900-S supports the iDatalink BLADE-AL universal bypass module.
This matters because many vehicles use a factory transponder key or immobilizer.
Simply powering the starter and ignition circuits may cause the engine to crank without actually starting.
A compatible bypass/interface module allows the remote-start system to communicate with the vehicle’s factory electronics.
Depending on the application, a BLADE-AL can handle functions related to:
- Immobilizer bypass
- Door locks
- Factory alarm
- Door status
- Tach data
- Brake status
- Trunk functions
- Vehicle data communication
Exact functionality varies by vehicle.
Is the BLADE-AL Included?
Not with the standard CS920-S bundle unless your specific package explicitly says otherwise.
The standard CS920-S should be treated as BLADE-AL compatible, not automatically as BLADE-AL included.
Compustar separately offers a CS920-S-KIT configuration that includes the BLADE-AL bypass module.
That distinction is important when comparing prices.
CS920-S
Includes the remote-start system.
CS920-S-KIT
Adds a BLADE-AL bypass module.
If your vehicle requires a bypass, factor that into the total installation cost.
Why Modern Cars Often Need a Bypass Module
Most vehicles built in the last couple of decades use some form of factory immobilizer.
The ignition key may contain:
- Transponder chip
- RFID element
- Smart-key authentication
- Coded security data
When the vehicle starts normally, the immobilizer verifies that authorization before allowing the engine to continue running.
An aftermarket remote starter has to work with that system rather than simply pretending it doesn’t exist.
If the bypass or immobilizer integration is incorrect, you may end up with a vehicle that cranks but will not start.
Our engine cranks but won’t start diagnostic guide covers why immobilizer faults should always be considered when the starter spins normally but the engine refuses to run.
Compatible With DroneMobile
The CM900-S is officially DroneMobile compatible.
With compatible additional DroneMobile hardware and service, the system can be expanded beyond traditional RF control.
DroneMobile can add smartphone-based features such as:
- Remote start
- Lock
- Unlock
- Vehicle status
- Connected alerts
- GPS-related features with appropriate hardware and plan
DroneMobile hardware is not included with the standard CS920-S.
Connected services can also require a paid subscription.
Start Basic, Upgrade Later
One nice feature of the Compustar ecosystem is that starting with a basic system doesn’t necessarily lock you into basic remotes forever.
The CM900-S supports multiple Compustar RF platforms.
That means an installation can potentially be upgraded later with compatible:
- Longer-range remotes
- 2-way LED remotes
- 2-way LCD remotes
- New antenna kits
- DroneMobile connectivity
Compatibility depends on the antenna and remote package selected.
This makes the CS920-S an appealing starting point for someone who wants basic remote start today but may want more range later.
Does the CS920-S Have an Alarm?
The standard CS920-S is primarily a remote-start and keyless-entry system, not the full Compustar alarm/security configuration.
If you want dedicated aftermarket security functions such as:
- Shock sensing
- Siren
- Security LED
- Tilt sensing
- Alarm-event monitoring
look at a Compustar remote-start/security system using a security-capable control module such as the CM900-AS.
The product names look similar, but the systems serve different purposes.
CS920-S vs. CS920-S-KIT
These are closely related products.
Compustar CS920-S
- Remote start
- Keyless entry
- CM900-S controller
- Two 1-way remotes
- BLADE-AL compatible
- Bypass module not necessarily included
Compustar CS920-S-KIT
- Remote start
- Keyless entry
- CM900-S controller
- Two 1-way remotes
- BLADE-AL bypass included
If your vehicle requires the BLADE-AL, the KIT version can provide a more complete hardware package.
CS920-S vs. Compustar CS4202-S
This comparison helps buyers decide whether 1-way control is enough.
CS920-S
- 1-way remote start
- Simple LED remotes
- Everyday range
- Lower entry price
- No command confirmation
CS4202-S
- 2-way remote-start configuration
- Longer-range control
- Command confirmation
- Better for vehicles parked outside line of sight
If you can see the vehicle from where you usually remote-start it, the CS920-S may be all you need.
If you’re constantly pressing START from three floors up and wondering whether anything happened, 2-way starts making a lot more sense.
1-Way vs. 2-Way Remote Start
This is the biggest decision when considering the CS920-S.
1-Way
You send the command.
The car receives it.
There is no remote confirmation.
2-Way
You send the command.
The car receives it.
The system sends confirmation back to the remote.
2-way systems cost more because they require more sophisticated RF hardware and remotes.
But not everyone needs that.
For a daily driver sitting 100 feet from the house, 1-way remote start can be perfectly practical.
Diesel-Engine Compatibility
The Compustar platform can support remote-start installations on compatible diesel vehicles when properly configured.
Diesel engines often require a wait-to-start delay so glow plugs or related systems have time to prepare before cranking.
Vehicle-specific installation and configuration are important.
Do not assume every diesel application uses the same timing.
Professional Installation Strongly Recommended
Remote-start installation involves much more than plugging a box into the OBD-II connector.
Depending on the vehicle, installation can involve:
- Constant 12V
- Ignition
- Accessory circuits
- Starter wiring
- Brake input
- Hood safety input
- Parking lights
- Power locks
- Trunk output
- Factory alarm
- Immobilizer bypass
- Vehicle data network
- Tach or engine-running detection
Professional installation is strongly recommended.
Incorrect wiring can cause no-start conditions, battery drain, electrical problems or unsafe remote-start operation.
Hood Safety Matters
A properly installed remote starter should prevent remote engine start when the hood is open.
Why?
Because someone working near belts, fans or other moving engine components should not have the engine suddenly start because a remote button was pressed.
This isn’t an optional convenience feature.
It is part of installing remote start correctly.
Brake Shutdown
Another critical safety input is the brake pedal.
Once the vehicle has been remotely started, pressing the brake without completing the proper takeover sequence should shut down the engine.
That helps prevent someone from simply entering a remotely running car and driving away.
Factory Immobilizer Integration
Remote start should work with the vehicle’s factory security system rather than permanently defeating it.
A properly configured bypass module provides temporary authorization during remote start.
It should not simply disable factory theft protection all the time.
That’s why vehicle-specific compatibility and correct programming matter.
