The short answer is that many modern cars offer the ability to start the engine using a smartphone app. This feature, commonly known as remote start via app, is primarily available on vehicles from brands that have a dedicated connected services subscription. Brands like General Motors (through OnStar), Ford (FordPass), Toyota/Lexus (Remote Connect), Hyundai/Kia (Bluelink/UVO Link), and Subaru (Starlink) are prominent examples. The key requirement is that the car must be equipped with built-in cellular connectivity, which allows it to communicate with the app over the internet from virtually any location.
This technology goes beyond the limited range of a traditional key fob remote start. With the app, you can start your car, lock or unlock the doors, and even check fuel level or vehicle location from miles away. This is incredibly useful for pre-cooling the cabin on a hot day or warming it up in the winter before you even step outside.
However, it's crucial to understand that this is typically a subscription-based service. After an initial trial period (often 1-3 years), you'll need to pay a monthly or annual fee to maintain the functionality. The availability of specific features can also vary significantly by manufacturer and even the vehicle's trim level.
| Brand | App/Service Name | Common Features (via App) | Typical Subscription Required After Trial? |
|---|---|---|---|
| General Motors | OnStar / myChevrolet, myGMC | Remote Start, Lock/Unlock, Vehicle Status | Yes |
| Ford / Lincoln | FordPass / LincolnWay | Remote Start, Lock/Unlock, Vehicle Location | Yes (for remote commands) |
| Toyota / Lexus | Toyota App / Lexus Enform | Remote Start, Climate Control, Valet Alert | Yes |
| Hyundai / Genesis | Bluelink | Remote Start, Last Parked Location, Curfew Alert | Yes |
| Kia | UVO Link / Kia Access | Remote Start, Geo-fencing, Speed Alert | Yes |
| Subaru | Starlink | Remote Start, Climate Control, Stolen Vehicle Recovery | Yes |
| Tesla | Tesla App | Remote Start (Climate), Summon, Location | No (included for standard connectivity) |
When shopping, look for terms like "connected services," "remote connectivity," or the specific app names on the manufacturer's website. Always confirm which features are included in the standard package and what the long-term costs will be.

My last car just had a key, but my new Ford Escape has the FordPass app. It’s a game-changer for school drop-off line. I can start the car and get the heat going while I'm still inside bundling up the kids. No more running out in the cold with a key fob. It also locks the doors for me if I forget, which happens more than I’d like to admit. Just check if it’s a subscription—my trial is almost up.

For a tech-focused perspective, smartphone start is part of the vehicle's telematics system. It relies on a built-in LTE modem, much like your phone. The app sends a command to a secure cloud server, which then pings the car. The real value is integration. My Hyundai app allows geofencing alerts and can even interface with my Google Home to start the car with a voice command. The future is API-driven functionality, moving beyond simple remote start to a fully integrated digital experience.

Beyond convenience, the security and peace of mind are underrated benefits. I travel frequently, and being able to start my Chevy from the airport terminal to ensure it’s running smoothly after sitting for a week is reassuring. I also use the app to double-check that the doors are locked from my hotel room. It’s not a gimmick; it’s a practical tool for vehicle management. Just be aware that after the first few years, you’ll likely have a monthly bill for the service.

I was skeptical at first, but after using Toyota’s app for a year, I’m sold. The ability to start my car from my office desk so the AC is blasting by the time I get to the parking lot is pure luxury. It’s also bailed me out when I couldn’t remember if I locked it after a grocery run. The key is to test the app's reliability during your test drive—some are faster and more intuitive than others. It’s a feature that, once you have it, you’ll wonder how you ever lived without.
