Yes, you can install a remote start system in most cars. The process and best option, however, depend heavily on your vehicle's age, model, and existing factory features. The two main paths are using a dealer-activated OEM (Original Equipment Manufacturer) system or an aftermarket kit installed by a specialist.
For newer vehicles, especially those with complex integrated computers, the safest bet is often an OEM accessory. This might be a physical remote fob add-on or a feature activated via a telematics system like GM's OnStar or FordPass. This ensures compatibility with your car's and engine management systems.
Aftermarket systems offer more versatility for older cars and often come at a lower cost. Professional installation is critical here. A certified installer will use interfaces like a T-harness—a plug-and-play adapter that minimizes wire splicing—to integrate with your car's wiring, reducing the risk of electrical issues. For key-start vehicles, a well-installed system should not void your warranty, as per the Magnuson-Moss Warranty Act, unless the installation is proven to have caused a failure.
If your primary goal is convenience from a distance, consider systems with two-way remotes that confirm the car has started, or smartphone-controlled systems that use an app and a cellular connection to start your car from virtually anywhere.
| Consideration | OEM System | Aftermarket System |
|---|---|---|
| Best For | Newer models with factory security | Older vehicles, broader compatibility |
| Cost Range | $300 - $650+ | $200 - $500+ |
| Installation | Dealership technician | Certified specialty installer |
| Integration | Seamless with factory key fob/app | May require separate remote or app |
| Reliability | High, designed specifically for the vehicle | High, when professionally installed |
| Warranty Impact | Typically none, covered by dealer | Minimal if installed correctly |
Ultimately, a professional installation is non-negotiable for a reliable and safe result. Get quotes from both your dealership and reputable auto electronics shops to make the best choice for your specific car.









I just had one put in my 2018 SUV. I went to a car audio and electronics shop, not the dealer. It cost me about $400 altogether, including the part and labor. They did it in a few hours, and now I have a separate fob to start it. Best money I've spent, especially on cold mornings. No issues with my car's warranty or anything. Just make sure you pick a place with good reviews.

Think about how you'll use it. If you just want to warm up the car in the driveway, a basic aftermarket system is fine. But if you want to start it from your office desk, you need a cellular-based app system, which costs more. Check your car's manual first; some luxury brands have remote start built-in but require a subscription to activate. Always, and I mean always, get a professional to install it. Messing with the car's electrical system yourself is asking for trouble.

The biggest worry for most people is voiding the warranty. The law is on your side here. A dealership cannot void your entire warranty just because you added a remote start. They would have to prove that the installation directly caused a specific problem, like an electrical short. To be safe, have it installed by a certified professional who uses quality parts and can provide documentation. This protects your investment and your car.

My son talked me into getting a remote start for my sedan. I was skeptical, but wow, what a difference it makes. I don't have to scrape ice off the windshield anymore, and the cabin is always comfortable when I get in. It feels like a luxury feature without the luxury price tag. I went with a well-known brand and had it installed at a specialist. It's been completely reliable. For anyone who deals with harsh weather, it's a game-changer for your daily routine.
