If you own a Jeep Grand Cherokee, you probably value comfort, convenience, and modern technology. One feature that can make your driving experience even better is remote start. With remote start, you can warm up or cool down your Grand Cherokee before you even open the door. This is a huge benefit during hot summers or freezing winters. But if your Jeep didn’t come with this feature, you might wonder how to add it. You’re not alone—many Jeep owners want to upgrade their vehicle with remote start for both practical and luxury reasons.
This guide will walk you through everything you need to know: options for adding remote start, step-by-step installation, costs, compatibility, important safety tips, and what to expect after installing. Whether you’re a DIY fan or prefer professional help, you’ll get clear, simple advice based on real-world experience.
Understanding Remote Start Systems
Before you begin, it’s important to understand what a remote start system does. With remote start, you can start your Jeep’s engine from a distance using a remote key fob or a smartphone app. This gives the heating or air conditioning time to adjust the cabin temperature before you get in. Some systems also let you lock/unlock doors, control windows, or even check vehicle status.
There are two main types of remote start systems:
- OEM (Original Equipment Manufacturer) – These are made by Jeep for your Grand Cherokee. They are integrated with your vehicle’s electronics and often come with a warranty.
- Aftermarket systems – These are made by other companies and can offer more features or lower prices. They may need extra wiring or adapters.
Both types have their pros and cons, which we’ll compare in detail below.
Should You Choose Oem Or Aftermarket?
Choosing between OEM and aftermarket remote start systems is a key decision. Here’s a quick comparison:
| Feature | OEM Remote Start | Aftermarket Remote Start |
|---|---|---|
| Integration | Seamless, uses factory wiring | May require extra adapters or wiring |
| Warranty | Often covered under Jeep warranty | May not be covered, possible risk to vehicle warranty |
| Features | Basic functions (start/stop, lock/unlock) | Advanced features (smartphone app, longer range) |
| Cost | Usually more expensive | Range from affordable to premium |
| Installation | Dealer or certified mechanic | Some DIY kits, or professional install |
OEM systems are best if you want a “factory feel” and worry about warranty issues. Aftermarket systems can be a better value and give you more control, but may need more careful installation.
Non-obvious insight: Some Jeep models need a software update or dealer programming after installing remote start—this is true even for OEM kits.
Compatibility: Is Your Jeep Grand Cherokee Ready?
Not every Grand Cherokee can use every remote start kit. Compatibility depends on:
- Year and trim – Most Grand Cherokees from 2011 and newer can add remote start, but details may vary.
- Factory key fob – Check if your key fob has a remote start button (a circular arrow). If not, you may need a new fob.
- Security system – Remote start needs to work with your Jeep’s anti-theft system. Some aftermarket kits include a “bypass module.”
- Push-button start vs. key ignition – Kits are different for push-button start and key-turn ignition.
Always check your Jeep’s manual or ask a dealer to confirm which kits will work.
What You Need For Installation
Gathering the right tools and parts is important for a smooth installation. Here’s what you’ll need:
- Remote start kit (OEM or aftermarket, matched to your Jeep’s year/model)
- Bypass module (for aftermarket kits, if needed)
- New key fob (if your current one doesn’t have remote start)
- Screwdrivers (flat and Phillips)
- Plastic trim removal tool
- Wire stripper and electrical tape (for aftermarket kits)
- Zip ties (to keep wires tidy)
- Owner’s manual (for wiring diagrams and fuse locations)
Practical tip: Always disconnect the battery before starting electrical work. This prevents short circuits or accidental airbag deployment.
Step-by-step: How To Add Remote Start To A Jeep Grand Cherokee
The installation process depends on the type of kit. Here’s a general guide for both OEM and aftermarket systems. Some steps may be different for your exact model, so always follow your kit’s instructions.
1. Preparation
- Park your Jeep in a safe, dry place.
- Disconnect the negative battery cable.
- Gather all tools and parts within easy reach.
2. Access The Wiring
- Use a trim tool to carefully remove panels under the steering column.
- Find the main ignition wiring harness (consult your manual or kit guide).
3. Connect The Remote Start Module
- For OEM kits, plug the module into the factory wiring harness. The connectors are usually color-coded.
- For aftermarket kits, you may need to splice wires. Match the kit’s wires to your Jeep’s wiring (ignition, brake, power, ground, etc. ).
- Attach the bypass module if required. This lets the remote start work with your Jeep’s security system.
4. Install The Antenna (if Needed)
- Some aftermarket kits use a separate antenna for better range.
- Mount the antenna near the windshield, away from metal parts.
5. Program The System
- For OEM, you may need to visit a Jeep dealer for programming. Some dealers charge $50–$150 for this service.
- For aftermarket, follow the kit’s programming steps. This usually involves turning the key or pressing the start button in a special sequence.
6. Test Everything
- Reconnect the battery.
- Test the remote start: Lock the doors, then press the remote start button.
- The engine should start, and the climate controls should turn on.
- Test all other functions (lock/unlock, panic alarm).
- If something doesn’t work, check all connections and programming.
7. Reassemble Panels
- Carefully put all trim panels back in place.
- Use zip ties to keep any new wires secure and out of the way.
8. Final Safety Check
- Make sure the hood and doors trigger the safety shutoff (the engine should turn off if the hood is opened).
- Test the brake override: The engine should shut down if you press the brake without the key present.
Expert tip: Take photos during disassembly. This helps you remember where each wire and panel goes.
Costs: What To Expect
Adding remote start to your Jeep Grand Cherokee varies in price:
- OEM kit parts: $250–$500
- Aftermarket kit parts: $100–$350
- Dealer installation/programming: $100–$300
- Professional install (aftermarket): $150–$250
So, the total cost can be anywhere from $200 to $800 depending on your choices. DIY installation saves money but requires confidence with car electronics.

Common Problems And Mistakes
Many first-time installers run into these issues:
- Wrong kit for your year/model – Always double-check compatibility.
- Missed programming step – Some kits need a dealer or special sequence to work.
- Loose or missed connections – A single loose wire can stop the whole system.
- Forgetting the bypass module – Without it, the Jeep’s security system may block remote start.
- Not testing before reassembly – Always test the system before putting panels back.
Non-obvious insight: Some remote start kits can drain your battery if not installed correctly. Make sure to follow wiring instructions closely.
Advanced Features: More Than Just Starting
Modern remote start kits offer extra features. Some examples:
- Smartphone app control – Start your Jeep from anywhere with your phone.
- 2-way confirmation – The remote tells you if your Jeep has actually started.
- Extended range antennas – Useful if you park far from your home or office.
- Automatic climate control activation – Pre-cools or pre-heats the cabin.
These features are usually found in premium aftermarket kits. OEM systems are reliable but may not support all these extras.
Safety And Legal Considerations
Remote start is safe when installed correctly, but there are a few important points:
- Never use remote start in a closed garage. This can cause dangerous carbon monoxide buildup.
- Check local laws. Some places have rules about idling cars or leaving engines running unattended.
- Don’t leave valuables in a running car. Thieves may target unattended vehicles, even if the doors are locked.
Quick fact: Most remote start systems will shut off the engine if anyone tries to drive away without the key fob present.

What To Expect After Installation
Once installed, you’ll enjoy much more comfortable drives. You can set the temperature before you get in, and you’ll save time scraping ice or waiting for the AC. Most users report no problems if they choose the right kit and follow instructions.
Two things often surprise new users:
- Your Jeep may shut off when you open the door, unless you follow a special procedure (this is normal for security).
- You’ll need to use the remote start sequence every time—there’s no “auto-schedule” unless your kit offers it.
If you ever have issues, check your kit’s manual, look for error lights on the module, or visit your installer/dealer.
