10 Best Subaru Remote Car Starters 2026 in the United States

The Start-X Remote Starter Kit is designed specifically for Subaru Legacy and Outback models from 2010 to 2014 that use a traditional key start and automatic transmission. Its main advantage is a true plug-and-play installation using a unique T-harness, meaning you won’t need to cut or splice any wires, which makes it approachable for those wanting a clean, factory-like setup. To start your car remotely, you simply press the lock button on your existing key fob three times. This simplicity is handy but also limits functionality since it doesn't come with a dedicated remote or two-way communication, so you won’t get confirmation if the car actually started or security alerts.

Setting up the starter requires a Windows PC to pair the device using a USB updater tool included in the kit, which might be inconvenient if you don’t have easy access to such a computer. The kit focuses on warming up your car quickly on cold mornings, saving you from waiting to defog windows. However, it only works with the specified Subaru models and won’t work if your vehicle has a push-button start or manual transmission.

Security-wise, it uses your factory key and remote, so it retains original locking protections but doesn’t add extra advanced security features. If you own a compatible Subaru and want a straightforward, reliable way to remote start your car without a complicated install, this kit fits well while noting its limited range of compatibility and the need for a Windows PC during setup.

The CSX9900AS Compustar 2-Way Remote Start with Security and LTE offers a solid option for Subaru owners looking to start their car remotely. It features a 4-button ergonomic remote that uses radio frequency, providing reliable communication with your vehicle. The two-way communication means you get confirmation when your car starts or locks, which adds peace of mind. The inclusion of LTE connectivity suggests extended range beyond traditional remote starters, allowing control through a smartphone app even when you're far from the vehicle.

Installation for Subaru vehicles is generally straightforward, but professional installation is recommended to ensure all security features work properly. This model includes standard antitheft functions to protect your car. The remote relies on a single CR2 battery, which is easy to replace but can run out without warning if not monitored.

This remote starter is a good fit for Subaru owners who want convenient long-range start and security features, but you should be prepared to invest in professional installation and keep an eye on battery life.

The Compustar CS7900-AS is a solid choice for Subaru owners looking for a remote car starter with a good range and added security. It offers an impressive remote range of up to 3000 feet, allowing you to start your car from a distance—great for warming up or cooling down your vehicle before you get inside. The system includes a loud 105 dB alarm siren to help deter thieves, enhancing your car's security. It comes with two remotes: a 2-way LCD remote that confirms commands have been received, and a backup 1-way remote for convenience. This 2-way communication provides instant feedback on whether your car has started or locked, saving you from guessing.

Compatibility is broad thanks to the ADS-BLADE AL integration cartridge, which supports over 4000 vehicle models from 1997 onward, so it should work well with most Subaru models. The product requires professional installation since it is not included, which might add to the overall cost and complexity. Some users may find the installation process a little technical due to the need for programming with the USB interface cable provided.

The system covers key features like remote start, keyless entry, and vehicle security, but it does not include any smartphone app control, which some newer models offer for added convenience. If you want a reliable remote start with solid range and security features and do not mind arranging professional installation, the Compustar CS7900-AS is a dependable option for your Subaru.
