2022 Jeep Wrangler — Key Fob Programming

Quick reference

Item	Detail
FCC ID	Varies by trim/options. Check the label inside your original fob and match it exactly. Do not order without verifying the FCC ID on your current fob.
OEM Fob PN	Varies by VIN. Your Jeep dealer can confirm the correct Mopar part number from your VIN. Multiple PNs were used in 2022.
Aftermarket Options	Refurbished OEM proximity fobs (match FCC ID/PN), and shell-only cases. Generic “universal” fobs typically will not program.
Battery Type	CR2450 coin cell (most 2022 Wrangler proximity fobs; confirm by opening your fob and reading the marking).
Programmable On-Board?	No — requires a dealer/locksmith scan tool with FCA Security Gateway access.
Cuts Required?	Yes — the emergency key blade inside the fob must be cut to your door locks.

Step-by-step on-board programming

DIY on-board programming is not supported on the 2022 Jeep Wrangler. Jeep moved to an encrypted proximity immobilizer with a Secure Gateway (SGW) beginning in this generation. Adding or erasing fobs requires a professional scan tool (wiTECH or equivalent) with authorized SGW access to place the RF Hub/BCM into key-learn mode and validate the vehicle security PIN.

What to do instead (professional programming workflow):

1. Obtain the correct fob

• Purchase an OEM or refurbished OEM proximity fob that matches your original fob’s exact FCC ID and Mopar part number. Mismatched IDs will not program.

2. Cut the emergency key blade

• Have a locksmith cut the blade by key code (preferred) or by duplicating your existing blade. Expect $20–$50 for cutting.

3. Schedule programming

• Bring all working fobs, the new fob, your driver’s license, and proof of ownership/registration. All keys that will continue to work usually must be present during programming.

4. Security access and key learn

• The technician logs into the FCA Security Gateway, retrieves/authorizes the PIN/seed, and puts the vehicle in key-learn mode. New fob(s) are then presented and learned to the RF Hub/BCM.

5. Verify functions

• Test Passive Entry (door handle touch), push-button start, remote lock/unlock, panic, and remote start (if equipped). Confirm the mechanical key operates the door and glovebox.

Tip: If your fob battery is weak, you can usually start by pressing the fob directly against the START button while pressing the brake.

Battery replacement

Most 2022 Wrangler proximity fobs use a CR2450 coin cell.

1. Release the emergency key: Press the side button and pull out the key blade.
2. Separate the case: Insert a plastic pry tool into the seam near the key-blade slot and gently twist to split the halves. Avoid metal tools to protect the seal and plastics.
3. Note battery orientation: Observe +/– orientation of the existing cell.
4. Remove the old cell: Lift it carefully without bending the spring contacts.
5. Install the new CR2450: Match the original orientation and press it flat under the contacts.
6. Reassemble: Snap the case halves together evenly; reinstall the emergency key.
7. Test: Verify lock/unlock and starting. If range is poor, re-open and confirm the battery is fully seated.

Where to buy a replacement fob

• Dealer (Mopar OEM)

  • Pros: Guaranteed correct part by VIN, latest firmware, full support.
  • Cons: Highest price; you’ll still pay programming.
  • Ballpark: $250–$450 for the fob, plus $100–$180 programming.

• Automotive locksmith (mobile or shop)

  • Pros: Usually lower total cost, fast mobile service, can cut the blade and program on-site.
  • Cons: Stock varies; insist on matching FCC ID/PN and a return policy.
  • Ballpark: $120–$260 for a refurbished/OEM fob, $120–$200 programming; total $240–$450.

• Online (Amazon/eBay)

  • Pros: Lowest part cost if you source a correct refurbished OEM fob; shells are inexpensive ($10–$20) if your electronics are good.
  • Cons: Risk of wrong FCC ID or previously “locked” fobs from salvage. You still need cutting and professional programming.
  • Ballpark: $60–$180 for a refurbished OEM proximity fob (part-only), $20–$50 cutting, $100–$200 programming.

If on-board programming isn’t supported

The 2022 Wrangler uses an FCA proximity (PEPS) immobilizer with an encrypted transponder integrated into the fob. The RF Hub/BCM will only accept new keys after an authorized login through the Security Gateway. These keys are not cloneable, and most previously programmed (used) fobs are permanently locked to their original VIN.

• Expectation and timing: A professional key add typically takes 15–45 minutes once the correct fob is on hand. Lost-all-keys situations can take longer and may cost $50–$150 more due to additional security steps.
• Cost planning: Expect $240–$600 total depending on source (dealer vs locksmith), region, and whether you have at least one working fob.
• Best practice: Add a spare while you still have a working fob; it’s faster and cheaper than a lost-all-keys scenario.
