Starting your 2018 Jeep Grand Cherokee remotely is a small luxury that can make your day easier. Whether it’s a cold winter morning or a hot summer afternoon, remote start lets you warm or cool your car before you step inside.
Many owners don’t realize just how simple it is to use this feature or that you can do it in a few different ways, depending on your model and equipment.
Let’s break down exactly how to remote start your 2018 Jeep Grand Cherokee, what you need to know, and some tips to get the most out of this feature.
Is My 2018 Jeep Grand Cherokee Remote Start Ready?
Before you try remote start, make sure your Grand Cherokee is equipped with this feature. Not all trims include it as standard. Look for a remote start button on your key fob—it usually shows a circular arrow. If you see that, your Jeep has remote start. For those without the button, check your owner’s manual or ask your dealer about upgrades.
How To Remote Start With The Key Fob
The easiest way to remote start your Jeep is using the key fob. Here’s what you do:
- Lock the doors: Press the lock button on your key fob once.
- Press remote start: Within five seconds, press the remote start button (the arrow) twice. The lights will flash and the horn may honk, signaling the command was received.
- The engine will start, and climate controls will activate based on your last settings.
Note: Your Jeep will run for about 15 minutes, then shut off if you don’t enter the vehicle and press the brake.
Quick Reference: Key Fob Remote Start
| Step | Action | Signal |
|---|---|---|
| 1 | Lock doors | Press lock once |
| 2 | Remote start | Press arrow button twice |
| 3 | Confirmation | Lights flash, horn honks |
Using Uconnect App For Remote Start
If your Jeep has Uconnect Access (a subscription-based service), you can start your vehicle using your smartphone. This works from almost anywhere with cell service.
- Open the Uconnect app on your phone.
- Log in to your account.
- Tap the Remote Start button.
- Wait for confirmation—the app will let you know when your Jeep starts.
This is especially useful if you’re far from your car or want to cool/heat it before heading out. Remember, Uconnect Access may require a paid subscription.
Uconnect App Vs. Key Fob
| Feature | Key Fob | Uconnect App |
|---|---|---|
| Range | About 300 feet | Virtually unlimited |
| Subscription Needed | No | Yes |
| Confirmation | Lights/Horn | Phone notification |
Important Remote Start Rules
Remote start on the 2018 Grand Cherokee has a few rules for safety:
- The car must be in park.
- Doors, hood, and liftgate must be closed.
- The check engine light must be off.
- The key fob must be within operating range (for fob method).
If any of these are not met, the remote start will not work.
Common Problems And Solutions
- Nothing happens: Make sure doors are locked and the car is in park.
- Engine shuts off immediately: There may be a problem with the hood latch or the “check engine” warning is on.
- No response from the app: Check your subscription and cell connection.
Practical Tips For Remote Start Use
- Set climate controls before you leave: The car remembers your last settings. For cold mornings, set your heater and defroster before you exit.
- Know the limits: Remote start will not work if the hood is open, or if there’s a major warning light.
- Double remote start: You can extend run time by repeating the remote start process once, for a total of 30 minutes.
- Don’t leave children or pets inside: The system is for comfort, not for leaving anyone unattended.
Many owners forget about the double remote start feature. This non-obvious trick can be helpful on very hot or cold days. Another tip: If you install aftermarket remote start, make sure it’s compatible with your Jeep’s electronics to avoid issues.
What To Do If Remote Start Isn’t Working
If your remote start doesn’t work, try these steps:
- Check the battery in your key fob. Weak batteries can reduce range or stop the system from working.
- Inspect all doors and the hood to make sure they’re closed.
- Look for warning lights on your dash. Fix any issues before trying again.
- Reset the system: Sometimes, disconnecting and reconnecting the car’s battery can reset electronics. If you’re not comfortable with this, visit your dealer.
