2016 Jeep Grand Cherokee Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2016 Jeep Grand Cherokee does not support DIY on-board key fob programming. This means you won't be able to program a new key fob yourself using a sequence of actions like turning the ignition on and off. The vehicle's security system requires specialized diagnostic equipment to link a new key fob to your Grand Cherokee. This procedure typically involves accessing the vehicle's onboard computer and performing a "learn" function for the new fob.

Battery replacement

1. Locate the small release button or tab on the side of the key fob. Press or slide it to release the emergency key blade. Pull the emergency key blade out.
2. With the emergency key blade removed, you'll see a small slot or indentation in the key fob housing. Use a small flathead screwdriver or a coin to carefully pry open the two halves of the key fob.
3. Gently remove the old CR2032 battery. Note the orientation (+/-).
4. Insert the new CR2032 battery with the positive (+) side facing up.
5. Carefully snap the two halves of the key fob back together until you hear a click.
6. Reinsert the emergency key blade.

Where to buy a replacement fob

• Chrysler/Jeep Dealership:

  • Pros: Guaranteed genuine OEM part, often comes with a warranty, programming typically included with purchase.
  • Cons: Most expensive option. Expect to pay anywhere from $250 to $400 or more for the fob and programming.

• Automotive Locksmith:

  • Pros: Often more affordable than the dealership, can come to your location (mobile locksmiths), can cut and program keys on-site. Locksmiths also often have access to both OEM and quality aftermarket fobs.
  • Cons: Prices can vary. Ensure the locksmith has experience with Jeep systems and uses reputable equipment. Expect to pay around $150 to $300 for the fob and programming.

• Online Retailers (e.g., Amazon, eBay):

  • Pros: Potentially the cheapest option for the fob itself.
  • Cons: You still need to find a locksmith or dealer to cut the emergency key blade and program the fob, which adds to the overall cost. There's also a risk of purchasing a counterfeit or incompatible fob. Prices for the fob alone can range from $50 to $150, but remember to factor in programming costs.

If on-board programming isn't supported

As mentioned, the 2016 Jeep Grand Cherokee requires specialized equipment for key fob programming. This means you'll need to visit a dealership or an automotive locksmith. The cost will depend on where you go, as outlined above. The key fob for your Grand Cherokee contains an immobilizer transponder chip, which is crucial for the vehicle to start. This chip needs to be correctly programmed to the vehicle's immobilizer system. If the transponder isn't programmed, even if the remote functions work, the car will not start. The emergency key blade also needs to be cut to match your vehicle's ignition and door locks, and this is typically done by a locksmith or dealer utilizing a key cutting machine.
