Yes, you can start a 2013 Civic from outside the car, but only if your vehicle is equipped with an optional remote engine start system. This was not a standard feature on all trims. The system allows you to activate the engine from a distance, typically up to 100-150 feet, using a dedicated key fob.
How It Works If your key fob has a circular arrow button (usually labeled with a "2x"), your car has the feature. To start the car, press the LOCK button once, then press and hold the remote start button for about two seconds. The car's lights will flash and the engine will start. The climate control will also activate, automatically setting itself to the last used temperature to begin heating or cooling the cabin. The engine will run for about 10 minutes before automatically shutting off to conserve fuel. You can extend the runtime by repeating the remote start process.
Key Limitations and Precautions For safety, the car will remain locked during the entire remote start cycle. The engine will shut off immediately if a door is opened without using the key, or if the brake pedal is pressed without the key fob being physically inside the vehicle. This is an important anti-theft feature. Also, the system will not engage if the hood is unlatched, the fuel level is critically low, or a check engine light is on.
Confirming Your Vehicle's Equipment The remote start feature was typically available on higher trims like the EX-L or as a dealer-installed accessory. If you're unsure whether your Civic has it, the simplest way to check is to look at your key fob. The presence of the extra button is the clearest indicator. If your fob doesn't have it, you can have an aftermarket system installed by a professional audio/security shop.
| 2013 Honda Civic Trim Level | Standard Remote Start? | Typical Key Fob |
|---|---|---|
| LX | No | Basic 3-button (Lock/Unlock/Trunk) |
| EX | Optional/Dealer-Installed | May have 4-button fob with circular arrow |
| EX-L | Optional/Dealer-Installed | May have 4-button fob with circular arrow |
| Si | No | Basic 3-button fob |
| Hybrid | No | Basic 3-button fob |

My 2013 Civic EX has it, and it's a lifesaver in winter. I just hit lock on the fob, then hold the little circular button. From my kitchen window, I can start the car and let it warm up for ten minutes. By the time I get the kids in their coats, the windshield is defrosted and the cabin is toasty. The car stays locked the whole time, so it's totally secure. Best option I ever got.

If your key fob has a button with a circular arrow, then yes, you can. Press lock once, then hold that arrow button. The lights will flash and it'll start. It'll only run for 10 minutes for safety and will shut off if you open the door without the key. If your fob is just the basic lock, unlock, and trunk buttons, your car didn't come with that feature from the factory.

I looked into this because I wanted to add it to my LX model. The factory system was an option, so check your fob first. If it's not there, you're not out of luck. A good car audio or shop can install an aftermarket remote start for a few hundred dollars. They work great and often have even longer range than the factory version. Just make sure you use a reputable installer.

The ability depends entirely on your car's original equipment. The system is designed with safety as a priority. When running remotely, the vehicle remains immobilized—the transmission is locked, and the steering wheel won't turn. It's really just conditioning the engine and cabin climate. You must use the physical key to unlock the doors and have it inside to actually drive away, which prevents someone from stealing the car while it's warming up.
