How To Remote Start Jeep Wrangler 2021

Okay, picture this: it's January. You're in Chicago (or, you know, anywhere that feels like Chicago in January). You're staring out the window at your Jeep Wrangler, which is currently sporting a fetching hat of snow. The only thing standing between you and a toasty commute is… actually getting into that frozen metal box. Been there? Yeah, me too.

That's when I remembered my 2021 Wrangler supposedly had remote start. "Supposedly" because, let's be real, who actually reads the entire owner's manual? (Don't lie, you don't.) So, after a frantic Google search involving a lot of shivering, I finally figured it out. And now, I'm here to save you from that same arctic blast.

This isn’t some kind of official Jeep document, by the way. This is just me, a fellow Wrangler owner, sharing what I learned. Think of it as the CliffsNotes to staying warm.

So, You Want to Remote Start Your 2021 Jeep Wrangler? Let's Do This.

First things first: Does your Wrangler actually have remote start? Not all trims come standard with it. Check your window sticker or build sheet. If you're unsure, there's a couple of ways to verify. See that key fob you're holding? Look for the remote start button. It looks like an arrow curving around a "x2" symbol. (Yeah, the icon designers could’ve been a bit more creative.) If you see that button, you're in business. If not... well, there might be aftermarket options, but that's a whole other can of worms.

Okay, assuming you DO have the button, let's get to the nitty-gritty. Here's the basic process:

• Press the Lock button. Just once. This is basically telling the system, "Hey, I'm serious. I want to start the engine."
• Press the Remote Start button twice. Two quick presses in rapid succession. Don't hold the button down, just press it twice. This is crucial. I spent a good five minutes holding the button down the first time. Rookie mistake.

And... that's it! (Assuming everything is working correctly, of course.) The engine should start, and your Wrangler will begin warming up/cooling down, depending on your climate control settings. Victory!

Troubleshooting: Because Life Isn't Always Easy

Sometimes, things don't go according to plan. (Surprise!) Here are a few common issues and how to deal with them:

• The engine doesn't start. This is the most common problem, obviously. Here's a checklist:
  • Are you close enough? Remote start has a limited range. If you're trying to start your Jeep from across the parking lot, it might not work. Try getting closer. (And maybe consider investing in a better antenna for your fob?)
  • Is the hood latched? If the hood isn't fully closed, the remote start system will be disabled. Safety first, people!
  • Are all the doors closed? Same principle as the hood. If a door is ajar, remote start won't work.
  • Is the check engine light on? A serious engine problem will prevent remote start from functioning. Get it checked out!
  • Is the fuel level low? Some systems disable remote start if the fuel is critically low. Because who wants to be stranded with a warm but empty gas tank?
  • Have you recently triggered the alarm? Sometimes a triggered alarm will disable the remote start until you manually start the vehicle with the key.
• The engine starts, then shuts off after a few seconds. This usually means the remote start timer has expired. The engine will run for a predetermined amount of time (usually 15 minutes) and then shut off automatically. You can extend the runtime (more on that later). Alternatively, this can also happen if the system detects an issue, like low oil pressure or overheating.
• The remote start button doesn't seem to do anything. It’s possible that the remote start system has been disabled. You can check your vehicle's settings (through the Uconnect system) to see if remote start is enabled. (And if you're not sure how to navigate Uconnect, well, that's another Google search for you!)

Customizing Your Remote Start Experience

Okay, you've mastered the basics. Now let's delve into some cool customization options (because who doesn't like to tinker?). This is where the Uconnect system comes into play. (Hope you're feeling tech-savvy!)

Here's how to access the remote start settings:

1. Start your Jeep. (Manually, with the key. Sorry, can't remote start this step!)
2. Go to the Settings menu on the Uconnect touchscreen. (It usually looks like a gear or a wrench icon.)
3. Look for the "Remote Start" or "Comfort & Convenience" (or something similar) option. The exact wording may vary depending on your Uconnect version.
4. Explore the settings! This is where the fun begins.

What can you customize? Here are some common options:

• Remote Start Duration: This is how long the engine will run when you remote start it. You can usually choose between 5, 10, or 15 minutes. If you live in a particularly cold or hot climate, you might want to extend the duration.
• Heated Seats/Steering Wheel on Remote Start: This is a lifesaver in the winter. You can set the heated seats and/or steering wheel to automatically turn on when you remote start the Jeep. Talk about luxury! (Though make sure your trim level actually has heated seats and a heated steering wheel, obviously.)
• Climate Control Settings: You can usually set the climate control system to automatically adjust to a specific temperature when you remote start the vehicle. This is great for pre-cooling or pre-heating the cabin. Pro tip: set it to “auto” and let the Jeep’s system figure it out. It’s usually pretty smart.
• Remote Door Unlock: Some vehicles allow you to configure whether the doors unlock after a remote start. This is a security feature that can prevent someone from simply hopping in your warmed-up Jeep and driving away.
• Horn with Remote Start: Some people like to have the horn honk when the vehicle successfully remote starts, providing audible confirmation. Others find it annoying. The choice is yours!

A Few Extra Tips and Tricks

• Consider the environment. Remote starting your car in an enclosed space (like a garage) is extremely dangerous due to carbon monoxide poisoning. Don't do it! (This should be obvious, but just in case…)
• Be mindful of idling laws. Some cities and states have laws that restrict how long you can idle your vehicle. Check your local regulations before remote starting your Jeep for an extended period.
• Keep your key fob in good condition. A damaged or weak battery in your key fob can affect the range and reliability of the remote start system. Replace the battery regularly. (And maybe invest in a protective case for your fob. Those things are surprisingly fragile!)
• Practice makes perfect. Don't get discouraged if you don't get it right the first time. Experiment with the remote start system and the Uconnect settings until you find what works best for you.
• The Uconnect app can be a lifesaver (if you subscribe). Many newer Wranglers come with the option to subscribe to Uconnect services, which allows you to control certain vehicle functions (including remote start) from your smartphone. This can be incredibly convenient, especially if you're out of range of your key fob. But be aware that it's a subscription service, so you'll have to pay a monthly or annual fee. (And honestly, sometimes the app is glitchy. But when it works, it's awesome.)

In Conclusion: Stay Warm (or Cool), My Friends

Remote starting your 2021 Jeep Wrangler isn't rocket science, but it can definitely make your life a lot more comfortable, especially during those extreme weather conditions. Once you get the hang of it, you'll wonder how you ever lived without it. So, go forth, experiment, and enjoy the convenience of a pre-warmed (or pre-cooled) cabin. And remember, if all else fails, consult your owner's manual. (Just kidding... mostly.)

Now, if you'll excuse me, I'm going to go remote start my Jeep and pretend I'm on a tropical island. It's all about the mindset, right?
