1. Compustar CS7900-AS: Best Overall
In our evaluation, the Compustar CS7900-AS stands out for its exceptional 3,000-foot range and robust 2-way LCD remote that confirms commands. Owner feedback highlights its reliable performance in extreme temperatures and the convenience of optional smartphone control. The system includes a shock sensor and starter kill, meeting high safety standards.
However, the CS7900-AS requires professional installation for most vehicles, which can be a barrier for DIY owners. If you need a budget-friendly option or a plug-and-play setup, consider a simpler model. This system is best for those who prioritize range and security and are willing to invest in professional installation.
- Longest range in its class with 2-way confirmation
- Built-in security features including shock sensor and starter kill
- Smartphone control via optional Drone Mobile module
Pros: Excellent range and reliable 2-way communication; Strong security integration
Cons: Professional installation recommended, adds to overall cost
2. Viper 5906V: Premium Smart Control
Based on manufacturer specs and owner feedback, the Viper 5906V delivers a powerful 1-mile range and a clear 2-way LCD remote. We compared its dual-stage shock sensor and starter kill to industry standards, finding it meets high security benchmarks. Users praise the vibration alerts and easy-to-read display.
That said, installation is not for beginners; it involves multiple wire connections and programming. If you prefer a simple DIY kit, this may not be ideal. The Viper 5906V is best for tech-savvy owners or those willing to pay for professional installation who want top-tier range and smartphone control.
- Long range with 2-way confirmation and vibration alerts
- Integrated security with dual-stage shock sensor
- Compatible with Viper SmartStart for app control
Pros: Excellent range and intuitive remote interface; Strong security features
Cons: Complex installation, may require professional help
3. Avital 5305L: Best Budget
We researched the Avital 5305L as a cost-effective entry point. Its 1,500-foot range is adequate for most users, and owner feedback indicates easy installation thanks to color-coded wires. The system includes basic security like valet mode, but lacks a starter kill or shock sensor.
The main limitation is the lack of 2-way confirmation; you won’t know if the car started until you see it. This system is best for budget-conscious owners who want simple remote start without advanced security. Skip it if you need 2-way feedback or smartphone control.
- Affordable system with reliable 1-way remote start
- Easy DIY installation with color-coded wiring
- Includes valet mode and remote trunk release
Pros: Very affordable for the features offered; Straightforward installation process
Cons: No 2-way confirmation, less security than higher-end models
4. Directed Electronics 5101P: DIY Friendly
In our evaluation, the Directed Electronics 5101P is designed for DIY installers. Its plug-and-play harness reduces wiring complexity, and owner feedback confirms a straightforward setup. The 1,000-foot range is sufficient for most driveways but may struggle in large parking lots.
Security features are minimal, with no shock sensor or starter kill. This system is best for those who want a no-fuss installation and basic remote start. Skip it if you need longer range or advanced security.
- Plug-and-play design for simple DIY installation
- Compact remote with start, lock, unlock, and trunk release
- Includes valet mode and programmable runtime
Pros: Very easy installation with pre-wired harness; Good value for basic remote start needs
Cons: Short range compared to competitors
5. Python 5706P: Long Range Value
Based on specs and aggregated owner reviews, the Python 5706P offers a 1-mile range and 2-way LCD remote at a lower cost than many competitors. We compared its shock sensor and starter kill to industry norms, finding them adequate for most users. Owners appreciate the temperature display and range.
However, the remote is larger than some alternatives, which may be a drawback. This system is best for those who want long range and 2-way confirmation without paying a premium. Skip it if you prefer a more compact remote or need smartphone integration.
- Exceptional 1-mile range with 2-way confirmation
- LCD remote shows vehicle status and temperature
- Includes security features like shock sensor
Pros: Long range at a competitive price point; Informative remote display
Cons: Remote can be bulky for some users
6. Fortin EVO-ALL: Best Universal Fit
We researched the Fortin EVO-ALL for its universal compatibility. It uses a T-harness and firmware updates to support many vehicles, including those with push-button start. Owner feedback notes that once programmed, it works reliably with the OEM remote.
The downside is that initial programming can be tricky, and not all vehicles are supported despite the universal claim. This system is best for owners who want to keep their OEM remote and need a versatile solution. Skip it if you want a straightforward installation or a dedicated remote.
- Universal design with T-harness for many vehicles
- Supports remote start via OEM remote or app
- Firmware updates available for new vehicles
Pros: Works with a wide range of vehicles including push-to-start; Can use existing OEM remote
Cons: Installation can be complex due to programming
7. Autostart AS-6270: Compact Design
In our evaluation, the Autostart AS-6270 is a basic, compact system. Its 800-foot range is below average, and the 1-way remote provides no feedback. Owner feedback indicates it gets the job done for short distances but lacks features.
Security is minimal with only valet mode. This system is best for those on a tight budget who need a simple remote start for a small vehicle or short range. Skip it if you need longer range, 2-way confirmation, or any advanced features.
- Compact module fits in tight spaces
- Simple 1-way remote with start and lock functions
- Basic security with valet mode
Pros: Very small size for easy mounting; Low cost
Cons: Short range and no 2-way confirmation
Frequently Asked Questions
Will an aftermarket remote start void my car warranty?
It depends on the installation. If the system is installed correctly by a professional and does not cause damage, it should not void your warranty. However, any modifications could potentially affect warranty coverage for related components. Always check with your dealer and installer.
Can I install a remote start myself?
Some systems are designed for DIY installation, like the Avital 5305L or Directed Electronics 5101P, with color-coded wires or plug-and-play harnesses. However, many modern vehicles require bypass modules and programming that may be complex. We recommend professional installation for most systems to ensure safety and functionality.
What is the difference between 1-way and 2-way remote start?
A 1-way remote sends a signal to start the car but does not confirm that the command was received. A 2-way remote provides feedback, such as an LED or LCD display, confirming the car started. 2-way systems offer peace of mind, especially at longer ranges.
How do I know if a remote start is compatible with my vehicle?
Check the manufacturer’s compatibility chart or use online tools. Many brands list compatible vehicles. Universal systems like the Fortin EVO-ALL cover a wide range but may require specific firmware. For push-to-start vehicles, you’ll need a system that supports that feature.
Are aftermarket remote starts safe?
Reputable brands comply with industry safety standards, such as automatic shutdown if the brake is pressed or the hood is opened. We recommend choosing a system with these safety features and having it professionally installed to avoid electrical issues.
Our Verdict
After researching specs, safety standards, and owner feedback, the Compustar CS7900-AS is our top pick for its exceptional range, robust security, and optional smartphone control. For a more budget-friendly option with 2-way feedback, the Python 5706P offers great value. Choose based on your priority for range, security, or ease of installation.
