Jeep Key Replacement, Key Fob Programming & Smart Key Service
From Y164 FOBIK fob-keys to M3N40821302 and OHT-4882056 smart fobs, we cut and program Jeep keys at your location across Palm Beach County.
Jeep keys follow the Chrysler group systems, from the Y164 keyway and the FOBIK fob-integrated key that you insert and twist, to the smart proximity fobs used on the Grand Cherokee, Wrangler JL, and Gladiator. Each style needs a different blank, chip, and programming path, so identifying the year and ignition type correctly is the first step on any Jeep key job.
Our mobile techs carry the blanks, cutters, and programming tools for the Jeep models most common in Palm Beach County, including the Wrangler and Grand Cherokee, with the Gladiator and Cherokee close behind. Whether you have lost every key or just want a spare, we confirm whether your Jeep is a FOBIK or push-to-start before we cut, and we tell you the price before we start.
Jeep models we service
Jeep key types by generation
Jeep keys changed significantly from one era to the next. The right blank, chip, and programming path depend on the year, trim, and ignition type, which is why we ask for the details before selecting a key.
2008 to 2013: Y164 FOBIK fob-integrated keys
Earlier Grand Cherokees used the FOBIK system (FCC IYZ-C01C), where the fob slides into a dash slot and twists like a key. The transponder lives inside the fob, so a fob that fits the slot still will not start the Jeep unless it is programmed to the immobilizer.
2014 to 2021: Grand Cherokee smart fobs
The Grand Cherokee and Durango family moved to a push-to-start smart fob (FCC M3N40821302) with a Y164 emergency blade inside. Lost proximity fobs are programmed to the specific vehicle, and all-keys-lost work often needs added time.
2018 to present: Wrangler JL and Gladiator smart fobs
The current Wrangler JL and the Gladiator use push-to-start smart proximity fobs (FCC OHT-4882056) with an emergency blade inside. Replacing a lost fob requires programming to the vehicle, and many all-keys-lost situations need additional time.
Jeep key data by model
Verified blank, chip, and FCC references are marked accordingly. Where a value depends on trim, button count, or production date, confirm it from the original key, a VIN lookup, or a supplier catalog before cutting or ordering.
Data is drawn from professional locksmith key references. It is a starting point for identification, not a guarantee for your specific vehicle.
Jeep Wrangler Key Replacement
The Wrangler moved from earlier Chrysler group keys to the current JL push-to-start smart fob, so the year and ignition type determine the fob and the emergency blade.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2007-2017 (JK) | Transponder / FOBIK by trim | Y164 emergency blade | Transponder built into key or fob | JK era; confirm FCC from original key or VIN | OBD programming | Y164 emergency insert | Confirm with original fob |
| 2018-2025 (JL) | Smart key (proximity, push-to-start) | Emergency blade inside fob | Smart-key immobilizer | FCC OHT-4882056 | Proximity programming; all-keys-lost may need extended access | Emergency insert | Verified from source data |
- •The JK body carried over alongside the new JL for part of 2018, so the same model year can use either system; have the original key handy so we match it.
Jeep Grand Cherokee Key Replacement
The Grand Cherokee spans the Y164 FOBIK fob-key and the push-to-start smart fob, so the year and ignition type tell us the fob and blade.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2008-2013 (FOBIK) | FOBIK fob-integrated key (insert and twist) | Y164 emergency blade | Transponder built into FOBIK fob | FCC IYZ-C01C (confirm by VIN) | OBD programming; all-keys-lost may need extended access | Y164 emergency insert | Confirm with original fob |
| 2014-2021 (push-to-start) | Smart key (proximity, push-to-start) | Y164 emergency blade | Smart-key immobilizer | FCC M3N40821302 | Proximity programming; all-keys-lost may need extended access | Y164 emergency insert | Verified from source data |
| 2022-2025 | Smart key (proximity, push-to-start) | Emergency blade inside fob | Smart-key immobilizer | Confirm FCC from original fob or VIN | Proximity programming | Emergency insert | Needs VIN confirmation |
Jeep Gladiator / Cherokee Key Replacement
The Gladiator shares the Wrangler JL smart fob, while the Cherokee uses a smart fob that varies by year and trim, so we confirm the exact key from the original or the VIN before cutting.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2020-2025 (Gladiator) | Smart key (proximity, push-to-start) | Emergency blade inside fob | Smart-key immobilizer | FCC OHT-4882056 | Proximity programming; all-keys-lost may need extended access | Emergency insert | Verified from source data |
| 2014-2023 (Cherokee) | Smart key (proximity) or FOBIK by trim | Y164 emergency blade | Smart-key immobilizer or FOBIK transponder | Confirm FCC from original fob or VIN | Proximity or OBD programming | Y164 emergency insert | Needs VIN confirmation |
- •The Cherokee key system varies by trim and year, so we confirm whether yours is a FOBIK or a true proximity smart key before we order or program.
Jeep Compass Key Replacement
The Compass uses a smart proximity fob on newer push-to-start trims and a transponder key on older models, so the year and ignition type determine the fob and the emergency blade.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2007-2017 | Transponder / FOBIK by trim | Y164 emergency blade | Transponder built into key or fob | Confirm FCC from original key or VIN | OBD programming | Y164 emergency insert | Confirm with original fob |
| 2017-2025 | Smart key (proximity) or transponder by trim | Emergency blade inside fob | Smart-key immobilizer or transponder | Confirm FCC from original fob or VIN | Proximity or OBD programming | Emergency insert | Needs VIN confirmation |
- •The Compass was redesigned in 2017, so a 2017 model year can be either the old body or the new one; tell us which so we bring the right key.
Common Jeep key problems
- •FOBIK fobs that no longer turn in the dash slot or start the Jeep after years of daily use.
- •Lost or water-damaged smart proximity fobs after a day at the beach, on the trail, or on the boat.
- •All-keys-lost situations on newer models that need extended security access and more time.
- •Buttons that stop responding on a FOBIK while the Jeep still starts.
- •Confusion between FOBIK insert-and-twist Jeeps and true push-to-start models of the same year.
Jeep programming notes
- •Adding a spare to a Jeep that already has a working fob is faster and cheaper than an all-keys-lost job.
- •FOBIK and push-to-start systems are not interchangeable, so we confirm the system before we order or program.
- •Smart proximity fobs are programmed to one specific vehicle and cannot be moved to another Jeep.
- •Many Chrysler group vehicles need extended security access for all-keys-lost programming, which adds time.

Jeep Key & Fob FAQs
Can you make a Jeep key if I lost all of them?
Yes. We generate and program a new fob from your Jeep, though all-keys-lost jobs on newer models can take longer because of the added security access required.
What is a FOBIK and does my Jeep have one?
A FOBIK is a fob-integrated key that you slide into a dash slot and twist to start the Jeep. If yours inserts and turns rather than pressing a button, it is a FOBIK (FCC IYZ-C01C era).
Do you program Wrangler JL and Gladiator smart fobs?
Yes. We supply and program push-to-start proximity fobs for the Wrangler JL and Gladiator (FCC OHT-4882056) and cut the emergency blade inside.
Is my Jeep FOBIK or push-to-start?
Both exist across these years. If you insert and twist a fob it is a FOBIK; if you press a button to start it is push-to-start. Tell us which so we bring the right key.
What does it cost to replace a Jeep key?
It depends on the year and whether it is a FOBIK or a smart proximity fob. We give you an up-front price over the phone before we head out.
Can you cut a spare Jeep key from my working one?
Yes, and a spare made while you still have a working fob is the cheapest key you will ever buy. We cut and program it on the spot.
Do you work on Jeeps at my home or job site?
Yes. We are fully mobile and come to your home, workplace, or wherever the Jeep is parked in Palm Beach County.
My Jeep fob turns but won't start. What's wrong?
The transponder in the fob talks to the immobilizer. If the fob fits the slot but the engine cranks without starting or shows a security light, the chip may have failed and the fob needs reprogramming or replacement.
Does the Grand Cherokee use the same key across all years?
No. Earlier Grand Cherokees use the FOBIK system and later ones use a push-to-start smart fob, so we confirm the year and ignition type before we order or program.
What information do you need to make a Jeep key?
The year, model, VIN, whether it is a FOBIK or push-to-start, and proof you own the Jeep. A photo of your existing fob helps us match it.
