1. Compustar CS7900-AS: Best Overall
In our evaluation, the Compustar CS7900-AS stands out for its exceptional range and two-way communication. The LCD remote provides clear confirmation that your car has started, and the 1-mile range is one of the best we’ve seen in this category. Based on owner feedback, the system is reliable in cold weather and the security features add peace of mind. However, installation can be complex for some vehicles, and we recommend professional installation to avoid wiring issues.
This system is ideal for drivers who want top-tier range and security. However, if you are looking for a budget-friendly option or a plug-and-play solution, you may want to consider a simpler model. The optional Drone module adds smartphone control at an extra cost, which may not appeal to everyone.
- Long-range 1-mile two-way communication with LCD remote
- Built-in security features including shock sensor and starter kill
- Supports smartphone control via optional Drone module
Pros: Excellent range and two-way feedback; Strong security integration
Cons: Professional installation recommended for most vehicles
2. Viper 5906V: Premium Pick
We compared the Viper 5906V and found its color LCD remote to be one of the most informative on the market. It displays real-time vehicle information such as interior temperature and battery voltage, which many users appreciate. The range is comparable to the Compustar, and the SmartStart module (sold separately) adds smartphone capabilities. Based on spec sheets, the system includes a dual-stage shock sensor and starter kill for security.
While the Viper offers premium features, its cost is higher than many alternatives. If you don’t need the color display or advanced vehicle data, a simpler remote may suffice. Some owners reported that the remote can be bulky, so consider that if you prefer a compact key fob.
- Color LCD remote shows vehicle status, temperature, and battery voltage
- Responder LC3 technology for extended range
- Compatible with Viper SmartStart for smartphone control
Pros: Informative color display with vehicle data; Long range and reliable two-way communication
Cons: Higher price point than comparable systems
3. Avital 5305L: Best Value
Based on our research, the Avital 5305L offers excellent value for those seeking basic auto start functionality. It provides a 1,000-foot range and includes keyless entry features, making it a practical upgrade. Owner feedback highlights its ease of installation on compatible vehicles, often requiring no wire splicing. However, it lacks two-way communication, so you won’t get confirmation that the car started.
This system is best for budget-conscious buyers who don’t need advanced features. If you require two-way feedback or longer range, consider spending more on a Compustar or Viper model.
- Affordable system with reliable 1,000-foot range
- Includes two 4-button remotes with lock/unlock and trunk release
- Plug-in design for easier installation on select vehicles
Pros: Great value for the price; Simple installation on many vehicles
Cons: No two-way confirmation of start
4. Start-X Remote Start Kit: Easiest Install
We evaluated the Start-X Remote Start Kit for its simplicity. It is a plug-and-play system that connects to your vehicle’s OBD-II port or harness, and you start the car by pressing the lock button three times. This makes it one of the easiest systems to install, and many users report success in under 30 minutes. However, the range is limited to that of your factory remote, which is typically much shorter than dedicated aftermarket remotes.
This product is ideal for those who want a quick, no-hassle installation and don’t need long range. If you have a vehicle that is not listed as compatible, you may face issues, and the lack of security features may be a concern for some.
- No wire cutting or splicing required for most vehicles
- Works with your existing factory remote (lock, lock, lock)
- Compact module hides behind dash
Pros: Extremely easy installation; Uses factory remote, no extra fob
Cons: Limited range of factory remote; Not compatible with all vehicle makes and models
5. Python 5706P: Good All-Rounder
We compared the Python 5706P and found it to be a solid mid-range option. It offers a 1,500-foot range, which is better than many 1-way systems, and the ability to add smartphone control via the SmartStart module. Owner feedback indicates reliable performance in moderate climates, but some have noted that the remote range can be affected by obstacles.
This system is suitable for those who want a balance of features and cost. However, if you prioritize two-way confirmation or advanced security, you may prefer a higher-end model. The installation requires some wiring, so professional help may be needed.
- Decent range of 1,500 feet for a 1-way system
- Built-in parking light flash and door lock/unlock
- Compatible with Python SmartStart module (sold separately)
Pros: Good range for a 1-way system; SmartStart compatible for smartphone control
Cons: No two-way confirmation
6. Auto Page RS-727: Long Range Specialist
We researched the Auto Page RS-727 and its standout feature is the impressive 2-mile range, which far exceeds most competitors. This makes it a good choice for large parking lots or properties. However, based on owner feedback, the build quality of the remotes and module has been inconsistent, with some reporting failures after a year. The system lacks two-way confirmation, so you won’t know if the start command was received.
This product is best for users who prioritize range above all else and are willing to accept potential durability trade-offs. If you need reliability and two-way feedback, look elsewhere.
- Exceptional 2-mile range for a 1-way system
- Includes two 5-button remotes with keyless entry
- Valet switch and parking light flash
Pros: Very long range; Multiple remote buttons for various functions
Cons: Build quality concerns reported by some users; No two-way communication
7. Crimestopper RS7-G5: Basic Budget
We evaluated the Crimestopper RS7-G5 as a no-frills option. It provides basic auto start and keyless entry at a low cost, but the range is limited to 800 feet and there is no two-way communication. Owner feedback indicates that it works adequately for short-distance use, but the remotes feel less durable than higher-end models. Installation can be tricky for some vehicles, and wiring diagrams are not always clear.
This system is suitable for those on a tight budget who only need basic functionality. If you require longer range, two-way feedback, or advanced security, you will be better served by spending more on a higher-rated product.
- Simple 1-way system with 800-foot range
- Includes two 4-button remotes
- Basic security features: door lock/unlock and trunk release
Pros: Lowest price point; Two remotes included
Cons: Short range compared to others; Limited features and no smartphone integration
Frequently Asked Questions
Can I install a remote start myself?
Some systems like the Start-X are designed for DIY installation with plug-and-play connectors. However, many aftermarket remote starts require wiring into your vehicle’s electrical system. We recommend professional installation for most systems to avoid damaging your car’s electronics and to ensure safety features like starter kill are properly connected.
Will a remote start work with a manual transmission?
Most remote start systems are designed for automatic transmissions. For manual transmissions, you need a special module that allows the system to verify the car is in neutral before starting. Some high-end systems like Compustar offer manual transmission-compatible versions, but they require extra installation steps. Always check compatibility with your vehicle type.
How far can a remote start reach?
Range varies widely. Basic 1-way systems have ranges from 800 to 1,500 feet, while premium 2-way systems can reach up to 1 mile. Some specialized models like the Auto Page RS-727 claim up to 2 miles. Actual range depends on obstacles, weather, and battery strength. If you need long range, look for systems with higher advertised range and two-way communication for confirmation.
Does remote start drain my car battery?
Modern remote start systems are designed to minimize battery drain. They typically draw very little current when not in use. However, if you frequently use remote start for long periods, it can put additional strain on the battery and alternator. Most systems have a built-in timer that shuts off the engine after a set time (e.g., 10-15 minutes) to prevent excessive drain.
Can I add smartphone control to my remote start?
Yes, many systems from Compustar, Viper, and Python offer optional smartphone modules (e.g., Drone, SmartStart) that allow you to start and monitor your car from anywhere with cellular coverage. These modules are sold separately and usually require a subscription for cellular data. They add convenience but increase the overall cost.
Our Verdict
After researching and comparing the top options, our top pick is the Compustar CS7900-AS for its exceptional range, two-way communication, and strong security features. For a more budget-friendly choice, the Avital 5305L offers reliable performance at a lower cost. Consider your priorities: range, ease of installation, or smartphone control to choose the best system for your needs.
