This remote is designed to be compatible with various Compustar remote start and security systems, offering reliable control over your vehicle's functions.

2. Setup and Programming
The Compustar 900R remote control requires programming to your vehicle's compatible Compustar remote start or security system before it can be used. Professional programming is highly recommended to ensure correct functionality and avoid potential issues.
2.1 Compatibility
The 900R remote is compatible with various Compustar systems, including CM-900X, CM2305-A, CM2500, CM900-AS, CM900-S, ANT-1WAM, and ANT-AP. It can also serve as a replacement for older models like the 700R and 600R.
2.2 Programming Instructions (General Guide)
These steps are a general guide. Specific vehicle models or Compustar systems may have variations. Always refer to your vehicle's specific Compustar system manual or consult a professional installer.
- Preparation: Gather all remote controls you wish to program for your vehicle. Ensure the vehicle's doors are closed. Do not start the engine. Keep your foot off the brake pedal throughout the process.
- Ignition Cycle: Insert your vehicle key into the ignition. Cycle the key from the OFF position to the ON position 5 times within 10 seconds. The ON position is the last ignition slot before the engine starts. The OFF position is where the key can be removed.
- Confirmation: After the 5th cycle, leave the key in the ON position. The vehicle's parking lights should flash once, indicating the system is in programming mode.
- Remote Programming: Press the LOCK button on the first remote you wish to program. The parking lights should flash once to confirm successful programming of that remote.
- Additional Remotes: If you have additional remotes (including existing ones), repeat step 4 for each remote. All remotes must be programmed during the same session, or previously programmed remotes may cease to function.
- Exit Programming Mode: After programming all remotes, wait approximately 7 to 10 seconds. The parking lights should flash twice, indicating the system has exited programming mode.
- Testing: Test all programmed remotes to ensure they lock/unlock and perform other functions correctly. If any remote does not work, re-attempt the programming process from step 1.
If you encounter difficulties, it is strongly advised to seek assistance from a certified Compustar installer.
3. Operating the Remote
The Compustar 900R features four distinct buttons for controlling your vehicle's functions. As a 1-way remote, it sends commands without receiving direct confirmation.
- Lock / Arm Button (
): Press this button to lock your vehicle's doors and arm the security system. - Unlock / Disarm Button (
): Press this button to unlock your vehicle's doors and disarm the security system. - Trunk / Auxiliary Button (
): This button typically controls the trunk release or an auxiliary function programmed into your system. Consult your system's manual for specific auxiliary functions. - Remote Start / Function Button (
): This button is used to initiate the remote start sequence or activate other programmed functions. Refer to your system's manual for specific usage.
4. Maintenance
Proper maintenance ensures the longevity and reliable performance of your remote control.
4.1 Battery Replacement
The remote control is powered by a small coin-cell battery. When the remote's range decreases significantly or it stops responding, the battery likely needs replacement. The battery type is typically a CR2032. To replace:
- Carefully open the remote casing, usually by prying it apart at a seam with a small, flat tool.
- Remove the old battery, noting its orientation (+/-).
- Insert a new CR2032 battery with the correct orientation.
- Snap the remote casing back together securely.
4.2 Cleaning and Storage
- Clean the remote with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Keep the remote dry and away from extreme temperatures.
- Avoid dropping the remote or subjecting it to strong impacts.
5. Troubleshooting
If you experience issues with your Compustar 900R remote, consider the following troubleshooting steps:
- Remote Not Responding:
- Check the battery. Replace if necessary.
- Ensure you are within range of the vehicle.
- Re-attempt the programming procedure (refer to Section 2.2).
- Limited Range:
- Replace the remote battery.
- Ensure there are no large obstructions or sources of radio interference between the remote and the vehicle.
- Only Some Functions Work:
- This may indicate an issue with the programming or the vehicle's Compustar system. Re-program all remotes. If the issue persists, consult a professional installer.
For persistent issues, contact Compustar customer support or a certified installer.
