2017 Jeep Grand Cherokee Key Fob Programming Guide

As an ASE-certified electrical technician and automotive locksmith, I see plenty of modern Jeeps roll into the shop for key and immobilizer issues. If you have lost a key fob for your 2017 Jeep Grand Cherokee, or you just want a spare for peace of mind, understanding your options can save you a significant amount of time and money.

In this guide for Repairius.com, we will cover everything you need to know about replacing, programming, and maintaining the smart proximity key fob for your 2017 Jeep Grand Cherokee.

Quick reference

Step-by-step on-board programming

If you are hoping to program a new key fob for your 2017 Jeep Grand Cherokee in your driveway using a sequence of button presses and door cycles, I have some bad news: DIY on-board programming is not supported for this vehicle.

Fiat Chrysler Automobiles (FCA) phased out on-board key programming for most of their lineup years prior to 2017. Because the 2017 Grand Cherokee utilizes a push-to-start proximity system, the vehicle’s immobilizer and Radio Frequency Hub (RFH) require a secure PIN code to authorize any new keys.

To program a new fob, the procedure is as follows (performed by a professional):

1. Connect Diagnostic Tool: The technician connects an advanced diagnostic scan tool (like an Autel MaxiIM or Smart Pro) to the vehicle's OBD-II port.
2. Pull the PIN Code: The tool communicates with the vehicle's immobilizer module to extract the unique 4-digit factory PIN.
3. Program the Proximity Fob: The tool pairs the unique RFID chip in the new fob to the vehicle's computer, authorizing it to bypass the immobilizer and start the engine.
4. Sync the Remote: The locking, unlocking, and remote start (if equipped) functions are synced simultaneously during the immobilizer programming.

Battery replacement

While you can't program the fob yourself, replacing a dead battery is incredibly easy. If your dashboard displays a "Key Fob Battery Low" message, follow these steps:

1. Remove the emergency key: Press the small silver release button on the back/bottom of the fob and pull the metal emergency key blade out.
2. Pry open the fob: Insert the tip of a flathead screwdriver (or the tip of the emergency key itself) into the notch right next to where the emergency key was seated. Gently twist to split the two halves of the plastic shell.
3. Remove the old battery: Carefully pop out the old battery, taking care not to damage the green circuit board.
4. Install the new battery: Insert a fresh CR2032 battery with the positive (+) side facing downward (against the back cover).
5. Reassemble: Snap the two halves of the key fob back together and reinsert the emergency key.

Where to buy a replacement fob

When sourcing a replacement key fob, you have three main options:

• The Dealership: The safest but most expensive route. An OEM fob from the dealer will cost between $150 and $250, plus an additional $100 to $160 for programming and cutting the emergency key. Pros: Guaranteed to work, OEM quality. Cons: Highest price.
• Local Automotive Locksmith: A great middle ground. Locksmiths can often supply high-quality aftermarket or refurbished OEM fobs. They will cut and program the key on-site, often coming directly to your location. Expect to pay between $180 and $250 total. Pros: Mobile service, lower overall cost. Cons: Must verify the locksmith's reputation.
• Amazon or eBay: You can find aftermarket fobs online for as little as $25 to $50. Pros: Extremely cheap hardware. Cons: Many aftermarket fobs are low quality, and some locksmiths refuse to program customer-supplied fobs due to high failure rates. Also, beware of "used" OEM fobs; once an FCA proximity key is programmed to a vehicle, it is permanently locked and cannot be reprogrammed to another Jeep without specialized virginizing equipment.

If on-board programming isn't supported

Since the 2017 Jeep Grand Cherokee requires specialized equipment to program the immobilizer transponder (typically an integrated Hitag proximity chip), you will need to factor labor into your replacement budget.

If you buy a key online, expect a local locksmith or shop to charge between $75 and $125 just for the programming labor and cutting the emergency blade. Be aware that if you lose all of your keys, the cost can be slightly higher, as the technician must generate a key from scratch rather than simply cloning the physical cut from an existing key.
