Starting your 2020 Jeep Wrangler from a distance can be a big help, especially in extreme weather. Remote start lets you warm up or cool down your vehicle before you get in. But using this feature the right way is important for safety and convenience.
If you’re new to remote start, or just want to use it more effectively, this guide will walk you through every step—plus tips most owners miss.
What Is Remote Start And How Does It Work?
Remote start is a system that lets you start your Jeep’s engine using your key fob or a smartphone app, without being inside the car. For the 2020 Jeep Wrangler, this feature is usually included with certain trim levels or as an optional package. When you use remote start, the Jeep’s climate control system turns on, so the interior can reach a comfortable temperature.
Your Jeep will stay locked during the process, keeping your vehicle safe. The engine will run for a set time (usually 15 minutes), then shut off if you don’t get in.
How To Remote Start Your 2020 Jeep Wrangler
Using remote start is simple, but you need to follow the correct steps for it to work reliably.
1. Check Safety Requirements:
Make sure all doors, hood, and tailgate are closed. The car must be in ‘Park,’ and the key must be outside the vehicle. If any door is open or the hood is unlatched, remote start will not work.
2. Locate Your Key Fob:
The 2020 Jeep Wrangler remote start uses the OEM key fob. Look for the button with a circular arrow.
3. Lock The Vehicle:
Press the lock button on your key fob once. The car should beep or the lights may flash.
4. Press And Hold Remote Start:
Within five seconds of locking, press the remote start button (circular arrow) twice. Hold it down until the lights flash or the horn chirps, indicating the engine has started.
5. Observe The Vehicle:
The parking lights will turn on while the engine is running remotely. This is a visual cue that your Jeep is on.
6. Enter And Drive:
To drive, unlock the vehicle with your fob, enter, and press the brake pedal. Insert the key or press the start button as you normally do. If you don’t enter within 15 minutes, the engine will shut off.
Common Mistakes To Avoid
- Forgetting to close a door or the hood will prevent remote start.
- Trying to start while the car is not in Park.
- Pressing the remote start button too slowly after locking.
Remote Start From Your Smartphone
Some 2020 Jeep Wranglers support remote start via the Uconnect app. This feature uses your phone’s internet connection, so you can start your Jeep from farther away than the key fob allows.
- Download the Uconnect App:
Available for iOS and Android.
- Register and Link Your Vehicle:
You’ll need your Jeep’s VIN and an active Uconnect subscription.
- Use the Remote Start Button:
The app interface has a remote start button, which works just like the fob.
Key insight: The app can show your Jeep’s status (locked, running, etc.) and let you start the engine even if you’re miles away.
How Far Can You Remote Start?
The key fob works up to about 300 feet (91 meters) in open areas. The Uconnect app can reach your Jeep anywhere you have cell or Wi-Fi service.
What If Remote Start Isn’t Working?
If remote start fails, here are things to check:
- All doors, hood, and tailgate are fully closed.
- The battery in the key fob is not low.
- The vehicle is in Park with the ignition off.
- No warning lights on the dashboard (like Check Engine).
If you see a flashing horn or lights but the engine doesn’t start, check the instrument cluster for error messages.
Quick Comparison: Key Fob Vs. App
Here’s a side-by-side look at the two main remote start options:
| Feature | Key Fob | Uconnect App |
|---|---|---|
| Range | Up to 300 ft | Unlimited (with cell/Wi-Fi) |
| Requires Subscription | No | Yes |
| Shows Vehicle Status | No | Yes |
| Works Without Cell Service | Yes | No |
Remote Start Safety Features
Jeep built in several safety features for remote start:
- Automatic shutoff after 15 minutes if you don’t enter.
- Engine stops if you try to drive without a key.
- Doors stay locked during remote start.
These features keep your Jeep safe from theft and prevent accidents.
Advanced Tips And Insights
1. Double Remote Start:
If you want your Jeep to run longer, you can repeat the remote start sequence once. This adds another 15 minutes (for a total of 30 minutes), but you must start the second cycle before the first ends.
2. Climate Control Memory:
Your Jeep’s climate settings (heat/AC) will use the last settings you chose. If you want warm air, set the heat before shutting off the engine. This small detail is often missed by new users.
3. Battery Life:
Using remote start often can drain your Jeep’s battery faster, especially in very cold weather. If you don’t drive long distances, check your battery health every few months.
Troubleshooting: Common Error Codes
Some error messages may appear if remote start fails:
| Error Message | Possible Cause | Fix |
|---|---|---|
| Remote Start Disabled – Start Vehicle to Reset | Multiple failed attempts | Start engine manually |
| Remote Start Not Available | Door/hood open, or warning light on | Check all closures, dashboard alerts |
| Key Fob Battery Low | Weak fob battery | Replace battery |
