2023 Jeep Gladiator Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

The 2023 Jeep Gladiator does not support DIY on-board key fob programming. This means you cannot program a new key fob yourself using a series of key turns or door open/closes. The sophisticated security systems in modern vehicles like the Gladiator require specialized equipment.

To program a new key fob for your 2023 Jeep Gladiator, a dealer or automotive locksmith must use a diagnostic scan tool. This tool connects to your vehicle's onboard computer and programs the new fob to communicate with your vehicle's immobilizer system. This is a critical security measure to prevent vehicle theft.

Battery replacement

1. Locate the small release button or tab on the side of the key fob. Press it to release the emergency key blade. Pull the emergency key blade out.
2. With the key blade removed, you'll see a small slot or indentation. Carefully insert a small flat-head screwdriver or a coin into this slot and gently twist to separate the two halves of the key fob casing.
3. Once the casing is open, you will see the circuit board and the CR2450 coin cell battery. Note the orientation of the battery (positive (+) side up or down).
4. Carefully pry out the old battery using a small screwdriver or your fingernail.
5. Insert the new CR2450 battery with the positive (+) side facing the same direction as the old one.
6. Align the two halves of the key fob casing and firmly press them back together until they click.
7. Reinsert the emergency key blade.

Where to buy a replacement fob

• Chrysler/Jeep Dealership:
  • Pros: Guaranteed genuine OEM part, often comes with programming included. They have the latest software updates.
  • Cons: Most expensive option, typically ranging from $300-$500 for the fob and programming.
• Automotive Locksmith:
  • Pros: Often more affordable than a dealership (typically $200-$400 for fob and programming). They come to you if mobile, saving towing fees. Can program both OEM and high-quality aftermarket fobs.
  • Cons: Quality can vary depending on the locksmith. Ensure they have experience with newer Jeep models.
• Online Retailers (e.g., Amazon, eBay):
  • Pros: Cheapest option for the fob itself (often $50-$150). Wide variety of OEM and aftermarket options.
  • Cons: The fob still needs to be programmed by a locksmith or dealer, adding to the total cost. Risk of purchasing a counterfeit or incompatible fob. You'll also need to get the emergency key blade cut separately.

If on-board programming isn't supported

As mentioned, the 2023 Jeep Gladiator requires professional programming. Expect to pay for both the key fob itself and the programming service. The vehicle's immobilizer system uses an encrypted transponder chip embedded within the key fob. This chip must be synchronized with your vehicle's computer (Powertrain Control Module - PCM) to allow the vehicle to start. Simply having a cut key blade will not allow the vehicle to start; the transponder must be programmed.

Cost Expectations:

• Dealership: $300 - $500+ (for fob, cutting, and programming)
• Automotive Locksmith: $200 - $400+ (for fob, cutting, and programming)

These costs can vary significantly based on your location and the specific vendor. Always get a quote before proceeding.
