2017 Jeep Cherokee Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2017 Jeep Cherokee does not support on-board (DIY) programming for new key fobs. This is because the vehicle is equipped with a sophisticated immobilizer system that requires a diagnostic scan tool to program new keys. This security measure prevents unauthorized individuals from easily programming a new key for your vehicle.

To program a new key fob, you will need to take your vehicle to a Jeep dealership or a qualified locksmith with the proper equipment. The scan tool communicates with the vehicle's computer to securely add the new key to the system. During this process, all existing keys will also need to be present, as they will be re-programmed at the same time.

Battery replacement

Replacing the battery in your 2017 Jeep Cherokee key fob is a simple task you can do at home.

1. Slide the mechanical release on the back of the fob to remove the emergency key blade.
2. Use the emergency key blade or a small flathead screwdriver to gently pry the two halves of the key fob apart. There is a small indentation to show you where to do this.
3. Carefully separate the two halves, being mindful not to damage the internal circuitry.
4. The CR2032 battery will be visible. Note the orientation of the old battery before removing it.
5. Remove the old battery and insert the new CR2032 battery, making sure the positive (+) side is facing up.
6. Snap the two halves of the key fob back together until they click into place.
7. Re-insert the emergency key blade.

Where to buy a replacement fob

• Jeep Dealership: This is the most expensive option, with prices for a new fob and programming often ranging from $200 to $400. However, you are guaranteed to get a genuine OEM part and programming by factory-trained technicians.
• Automotive Locksmith: A professional locksmith is often a more affordable option than the dealership, with prices typically ranging from $150 to $300 for the fob and programming. Many locksmiths are mobile and can come to your location.
• Online Retailers (Amazon, eBay): You can find aftermarket key fobs online for as little as $20-$50. While this is the cheapest way to acquire a fob, you will still need to have it programmed by a locksmith or dealer. Be cautious of the quality of aftermarket fobs, as some may not be as reliable as OEM parts. You will also need to have the emergency key blade cut.

If on-board programming isn't supported

As mentioned, the 2017 Jeep Cherokee requires a professional with a diagnostic scan tool to program new key fobs. This is due to the vehicle's immobilizer system, which uses a transponder chip in the key fob to communicate with the vehicle's engine control unit (ECU). Without the correct signal from a programmed transponder, the vehicle will not start.

When you take your vehicle to a locksmith or dealer, they will hook up a scan tool to the OBD-II port. They will then use the tool to put the vehicle into a secure programming mode, which allows the new key fob's transponder to be registered with the vehicle's computer. The cost of this service typically includes both the key fob and the labor for programming.
