1. Compustar CS7900-AS: Best Overall
The Compustar CS7900-AS is a top-tier remote start system that we found consistently praised in owner feedback for its reliability and range. When paired with the DroneMobile module (sold separately), it offers full smartphone control including remote start, lock/unlock, and GPS tracking. The system’s two-way remote provides confirmation, and the app interface is intuitive. Based on manufacturer specs, it supports a wide range of vehicles, but professional installation is strongly recommended to ensure proper integration with your car’s security system.
However, the additional cost for the smartphone module and installation may push this beyond budget for some. Owners with older vehicles or those who prefer a simple DIY setup might find the complexity a drawback. We recommend this for drivers who want a premium, fully-featured system and are willing to invest in professional installation.
- Two-way LCD remote with 3000 ft range; optional DroneMobile module for phone control
- Supports remote start, lock/unlock, and trunk release via app
- Professional installation recommended; compatible with most vehicles
Pros: Reliable long-range remote; Excellent smartphone integration with DroneMobile; Robust security features
Cons: Professional installation required adds to overall cost
2. Viper 5906V: Best Smartphone Integration
The Viper 5906V stands out for including the SmartStart module right in the box, which we found to be a significant value advantage. The app provides reliable remote start, lock/unlock, and even allows you to check vehicle status. Based on aggregated owner feedback, the system is generally dependable, though some users have noted sporadic app connectivity problems, especially in areas with weak cellular signal. The remote itself offers a respectable 1-mile range.
Installation is complex and professional help is advised. Those who want a simple plug-and-play solution may be frustrated by the wiring requirements. This is a great pick for tech-savvy owners who want robust smartphone features without buying extra modules.
- Responder LCD remote with 1 mile range
- SmartStart module included for phone control via app
- Supports remote start, lock/unlock, and alarm status
Pros: Excellent app interface with real-time alerts; Includes smartphone module in the box; Good range for most daily use
Cons: Some users report occasional app connectivity issues
3. Start-X Remote Starter Kit: Best Budget Option
The Start-X Remote Starter Kit is a budget-friendly solution that we evaluated for its simplicity. It connects directly to your vehicle’s OBD2 port and some specific wiring harnesses, making it one of the easiest systems to install yourself. Owner feedback highlights that it works well for basic remote start using the factory key fob, but the range is limited to that fob’s range. An optional smartphone module can be added, but that increases the cost.
However, compatibility is restricted to a list of supported vehicles (mostly Honda, Toyota, and some Nissan models). If your car isn’t on that list, this won’t work. Also, it lacks advanced security features like alarm integration. We recommend this for budget-conscious drivers with compatible vehicles who want a no-fuss install.
- No wiring required; plugs into OBD2 port and some specific connectors
- Works with factory remote or optional smartphone module (sold separately)
- Range limited to factory remote range; app range depends on cellular
Pros: Very easy DIY installation; Low price point for basic remote start; No cutting or splicing wires
Cons: Limited vehicle compatibility; No two-way confirmation
4. DroneMobile X1-LTE: Best for Universal Compatibility
The DroneMobile X1-LTE is a universal add-on module that we found ideal for vehicles already equipped with factory remote start. It simply plugs into the OBD2 port and connects to your smartphone via LTE, providing unlimited range. Owner feedback indicates the app is user-friendly and reliable, though a few users have experienced slight delays in commands. It also offers GPS tracking and vehicle status.
The main limitation is that it does not add remote start to a car that lacks it; you need the factory system first. Also, it relies on cellular service, so it won’t work in areas with no signal. This is a great pick for those who want to upgrade their existing remote start with phone control without complex wiring.
- Plugs into OBD2 port; works with any car that has remote start capability
- Smartphone app with unlimited range via cellular
- Adds remote start, lock/unlock, and GPS tracking
Pros: Works with any vehicle that already has factory remote start; Easy installation (plug and play); No monthly fees (uses your phone's data)
Cons: Requires existing factory remote start system; Some users report occasional app lag
5. Avital 5305L: Best Value with Smartphone Control
The Avital 5305L is a solid entry-level system that we found offers good value for those who primarily want a reliable remote start with a two-way remote. The 1-mile range is sufficient for most daily use, and owner feedback highlights its consistent performance. However, to get phone control, you must purchase the separate smartphone module, which adds to the overall cost. The app itself is functional but lacks the polish of competitors.
Installation is complex and professional installation is recommended. This system is best for those who want a dependable remote start and are okay with using the remote most of the time, with phone control as an occasional bonus.
- Two-way LCD remote with 1 mile range
- Smartphone module sold separately for app control
- Includes remote start, lock/unlock, and trunk release
Pros: Affordable price for a two-way system; Good remote range; Reliable basic functions
Cons: Smartphone module costs extra; App interface feels dated
6. Python 5706P: Best Security Features
The Python 5706P is designed for those who prioritize security along with remote start. We noted that its built-in alarm system with shock sensor and starter kill provides added peace of mind. The two-way remote confirms commands, and the range is a solid 1 mile. Owner feedback generally praises its reliability, though a few users have experienced false alarms from the shock sensor in windy conditions. Smartphone control requires the separate SmartStart module.
Installation is complex and best left to professionals. This system is ideal for drivers who want a robust security system integrated with remote start, and who don’t mind buying the extra module for phone control.
- Two-way remote with 1 mile range and confirmation
- Built-in security system with shock sensor and starter kill
- Compatible with SmartStart module for phone control (sold separately)
Pros: Excellent security features; Good remote range; Two-way confirmation
Cons: Smartphone module not included; Some users report false alarms from shock sensor
7. CarLink PRO: Best for DIY Installation
The CarLink PRO is a straightforward OBD2 device that we found appeals to DIYers who want a quick setup. It simply plugs into your car’s OBD2 port and uses your smartphone to control remote start (if your car has it), lock/unlock, and tracking. Owner feedback is mixed: many appreciate the ease of installation, but some report app connectivity problems and occasional delays. The unlimited range via cellular is a plus.
However, it does not add remote start to vehicles without it, and it relies on your car’s existing system. Those without factory remote start should look elsewhere. We recommend this only for owners of compatible vehicles who want a simple, no-fuss phone control solution and are willing to tolerate occasional app quirks.
- OBD2 plug-in; no wiring needed
- Smartphone app with unlimited range via cellular
- Supports remote start, lock/unlock, and vehicle tracking
Pros: Very easy installation; Works with most vehicles (1996 and newer); No monthly fees
Cons: Limited to vehicles with factory remote start; App reliability issues reported by some users
Frequently Asked Questions
Can I install a phone-controlled remote start myself?
Some systems like the Start-X or CarLink PRO are designed for easy DIY installation via OBD2 plug-in, but most premium systems require professional installation to ensure proper integration with your vehicle’s security and electrical systems. We recommend checking your skill level and the system’s requirements before attempting installation.
Do I need a subscription for smartphone control?
Many systems require a separate smartphone module (e.g., DroneMobile or SmartStart) that may have a monthly or annual fee for cellular connectivity. Some systems like the CarLink PRO or DroneMobile X1-LTE use your phone’s data and have no additional fees. Check the product details before purchasing.
Will a remote start system work with a manual transmission?
Most remote start systems are designed for automatic transmissions due to safety concerns. Some advanced systems can be installed on manual transmissions with additional safety features like neutral safety switches, but this is not common. Always verify compatibility with your vehicle’s transmission type.
How far away can I start my car with my phone?
With smartphone control, the range is effectively unlimited as long as both your phone and the car’s module have cellular or internet connectivity. However, some systems rely on Bluetooth or Wi-Fi, which have limited range. Most modern phone-controlled systems use cellular, so you can start your car from anywhere with a signal.
Will a remote start void my car's warranty?
If installed correctly by a professional, a remote start system should not void your factory warranty. However, any damage caused by improper installation could void coverage for affected components. We recommend using a certified installer and keeping records of the installation.
Our Verdict
After researching and comparing the top phone-controlled remote start systems, our top pick is the Compustar CS7900-AS for its robust performance, excellent smartphone integration, and strong security features. For those seeking a more budget-friendly option with easy installation, the Start-X Remote Starter Kit is a solid runner-up, provided your vehicle is compatible.
