The Jeep Grand Cherokee is everywhere in Tarrant County, and the generations sold from 2005 through 2021 used three completely different keys. A 2006 key, a 2010 key and a 2016 key have nothing in common except the badge. If you are down to one working key, or none, this page tells you which design your year takes and what it costs to replace. Call or text 817-842-1256 with the year and whether the vehicle has a start button and we will confirm the rest.
The Short Answer
As of October 2026, a 2005 to 2007 Grand Cherokee uses a remote-head metal key, a 2008 to 2013 model uses a FOBIK pushed into the dash, and a 2014 to 2021 model uses a proximity fob with push-button start. Remote-head keys and FOBIKs run $120 to $200 with a working key present; proximity fobs run $220 to $500; with no working key expect $180 to $450. A second key in the same visit is about $65.
Generation Reference
| Model years | Generation | Ignition | Key type | Emergency or main blade | Chip family | Remote FCC ID commonly fitted |
|---|---|---|---|---|---|---|
| 2005-2007 | WK | Turn key in column lock | Remote-head key | Edge-cut blade (Y164 profile) | Philips ID46 (HITAG 2) | OHT692427AA, 315 MHz |
| 2008-2010 | WK | FOBIK in dash slot (WIN) | FOBIK | Slide-out edge-cut emergency blade (Y159 profile) | Philips ID46 (HITAG 2) | IYZ-C01C, 433 MHz |
| 2011-2013 | WK2 | FOBIK in dash slot; push-button optional | FOBIK, with or without Keyless Enter-N-Go | Slide-out edge-cut emergency blade (Y159 profile) | Philips ID46 (HITAG 2) | IYZ-C01C, 433 MHz |
| 2014-2021 | WK2 | Push-button start | Proximity fob | Slide-out emergency insert | NXP ID46 (HITAG 2) | M3N-40821302, 433 MHz |
Treat the FCC IDs as the ones most commonly fitted, not as a guarantee for your vehicle. Button counts vary with options such as remote start and power liftgate, and more than one variant exists in several of these years. The identifier that settles it is the one molded into the fob you are holding. We give the same caution in every reference on this site, including the Ford Fusion key reference, the Camaro key reference and our guide to the Colorado key.
2005 to 2007: The Remote-Head Key
The first three years of the WK Grand Cherokee start with a conventional metal key in a lock cylinder on the steering column. The head of the key carries the lock, unlock and panic buttons, so the key and the remote are one part.
Inside the head is a transponder chip from the Philips ID46 family. It has no battery of its own for the starting function. A coil around the lock cylinder energizes it when the key is turned, and it replies with a code the vehicle must recognize. Chrysler called the system Sentry Key, and the module that checks the code is the Sentry Key Immobilizer Module. The National Highway Traffic Safety Administration describes this kind of immobilizer as the reason an engine will not run on a key that merely fits the lock.
Practical notes for these years:
- A hardware-store copy will not run the engine. It opens the doors and turns the ignition. The engine starts and stalls within a couple of seconds, with the security light on. See anti-theft light flashing and the car won't start.
- The remote and the chip fail separately. Dead buttons with a car that still starts means the remote half or its battery. A car that will not start with working buttons means the chip. Our comparison of transponder keys versus key fobs explains the split.
- These are now 19 to 21 years old. Worn blades in worn cylinders are common. If the key has started to stick, read ignition switch vs ignition cylinder before assuming the key is the only problem.
A recall that affects these years
In 2014 Chrysler recalled roughly 790,000 vehicles, the 2005 to 2007 Grand Cherokee and the 2006 to 2007 Commander, because a driver's knee could bump the key and move the ignition out of the Run position, shutting off the engine and disabling the airbags. It is a free dealer repair. If you own one of these, run the VIN through the NHTSA recall lookup before paying anyone to chase an intermittent stall.
2008 to 2013: The FOBIK
For 2008 the metal key disappeared. In its place came the FOBIK, short for fob-integrated key: a rectangular plastic fob with a blunt nose. You push the nose into a slot in the dash and rotate it, exactly as you would a key, but there is no blade and no tumbler lock. The slot is the Wireless Ignition Node, usually shortened to WIN, and it reads the fob's chip directly.
A small metal emergency blade slides out of the fob body. Its only job is to open the driver door when the fob battery or the vehicle battery is dead.
2011 to 2013: the WK2 redesign
The all-new WK2 body arrived for 2011 and kept the FOBIK, commonly under the same FCC ID. What changed was the option of Keyless Enter-N-Go. On vehicles so equipped, the fob stays in your pocket and the engine starts from a button. On these years the start button is a cap fitted over the same ignition node, and it can be pulled off so the fob can be inserted and turned in the traditional way. That is the backup when the fob battery dies, and it surprises a lot of owners who never knew the button came off.
Practical notes for the FOBIK years:
- The WIN module is the weak point, not the fob. A FOBIK that will not turn, turns but does nothing, or works only when wiggled often indicates wear in the node. See the key turns but nothing happens.
- FOBIKs look identical across many Chrysler, Dodge and Jeep models and are not interchangeable. Frequency, button count and proximity capability all vary.
- A used FOBIK is usually locked to its first vehicle. Buying one from another Jeep is the most common way to waste money on these years. We cover it in aftermarket key fob won't program.
2014 to 2021: The Proximity Fob
The 2014 refresh made push-button start standard and replaced the FOBIK with a proper proximity fob, commonly identified by FCC ID M3N-40821302 and transmitting at 433 MHz. It has the familiar rounded Jeep shape with up to five buttons depending on remote start and liftgate options.
The vehicle detects the fob through antennas in the cabin and the door handles. The module in charge is the Radio Frequency Hub, or RF Hub, usually mounted at the rear of the vehicle. It authorizes both entry and starting, and it is the part that new keys are programmed into. When an RF Hub fails, every fob stops being detected at once, which is why a sudden total loss of both fobs points at the vehicle and not at the fobs. Our service page on Dodge and Jeep RF Hub issues covers that failure.
If the fob battery dies, hold the nose of the fob directly against the start button and press with the fob itself. The button contains a short-range reader for exactly this situation. If that fails too, work through our push-button start diagnostic.
2018 and later: the secure gateway
Beginning with the 2018 model year, Chrysler-group vehicles gained a secure gateway module between the diagnostic port and the rest of the vehicle network. It refuses commands from a tool that has not been authenticated. Key programming is one of the functions it guards.
For an owner this changes nothing visible. For the locksmith it adds an authentication step. Credentialed access for independent shops is organized through the registry run by the National Automotive Service Task Force, which exists so that vetted professionals can perform security work after verifying ownership. It does not make the dealership the only option.
A recall that affects these years
In 2016 the manufacturer recalled roughly 811,000 vehicles in the United States, including the 2014 and 2015 Grand Cherokee, because the electronic gear selector returned to center after each shift and drivers could leave the vehicle believing it was in Park when it was not. The remedy was a software change that shifts to Park automatically when the driver door opens. It matters here because Federal Motor Vehicle Safety Standard 114, which NHTSA administers, ties key removal and vehicle shutdown to the transmission being in Park, and a vehicle that will not shut off or will not release is easily mistaken for a key fault.
What Is Not Covered Here
The redesigned Grand Cherokee introduced for 2022, and the three-row Grand Cherokee L that preceded it by a model year, use a different fob and a newer encrypted chip family. Nothing from the 2014 to 2021 generation fits. The 1999 to 2004 generation before the WK used an earlier Sentry Key design with a separate remote. Call with the year for either one.
What Each Grand Cherokee Key Costs in Fort Worth
As of October 2026:
- 2005 to 2007 remote-head key, a working key present: $120 to $200, cut and programmed on site.
- 2008 to 2013 FOBIK, a working key present: $120 to $200.
- 2014 to 2021 proximity fob, a working fob present: $220 to $500.
- No working key at all, any of these years: $180 to $450, including ownership verification and immobilizer access.
- A second matching key during the same visit: about $65.
Those are the standard bands used across this site, including our Jeep key replacement guide and the Jeep brand page. For the reasoning behind fob pricing see how much to replace a key fob, and for the full menu see how much is a locksmith for a car.
For perspective, AAA's Your Driving Costs research, published through the AAA newsroom, has put the average annual cost of owning and operating a new vehicle at around $12,000. A second key is one of the smallest lines in that budget and one of the few that prevents a much bigger one.
Which Grand Cherokee Do I Have?
- Is there a start button, and no slot behind it? A 2014 to 2021 vehicle with a proximity fob.
- Is there a start button that pulls off to reveal a slot? A 2011 to 2013 vehicle with Keyless Enter-N-Go.
- Do you push a plastic fob into the dash and turn it? A 2008 to 2013 FOBIK vehicle.
- Do you turn a metal key with buttons on its head? A 2005 to 2007 vehicle.
- Confirm with the VIN. The tenth character is the model year. Then read the FCC ID from the back of your own fob.
The PIN and Why All-Keys-Lost Costs More
Every one of these Grand Cherokees requires a security PIN before a key can be added. With a working key and the right equipment the PIN is obtained and the new key is enrolled in one short session. With no working key, ownership has to be verified first, the vehicle has to be opened, the emergency blade has to be originated from a code or by decoding the door lock, and the immobilizer has to be accessed without a key to vouch for the session. Same parts, more work. The steps are described on our all keys lost page.
Bring registration or title in your name and a matching photo ID. Proof of ownership is required before any key is made for a vehicle that has none.
Why These Vehicles Need a Programmed Key at All
The Grand Cherokee has had an immobilizer throughout this period, and the reason is theft. NHTSA's vehicle theft prevention material notes that more than a million vehicles are reported stolen in the United States in a typical recent year. The Highway Loss Data Institute, affiliated with the Insurance Institute for Highway Safety, has reported that immobilizers were standard on 96 percent of 2015 to 2019 models from most manufacturers, and that vehicles lacking them drew far higher theft claims. A key that has to be introduced to the vehicle is an inconvenience on the day you lose one and a protection on every other day.
What the Trade Says
"On a Grand Cherokee the first thing I ask is whether the key goes in the dash or stays in your pocket. That one answer tells me the generation, the module I will be talking to and which band the price is in. The second thing I ask is how many keys still work, because that decides whether it is a short visit or a long one." — an ALOA-credentialed Master Automotive Locksmith working the DFW metro
When to Call
Call when you are down to one working key, when a fob has stopped being detected, or when every key is gone. Have the year, whether there is a start button, how many keys still work and where the vehicle is parked.

Frequently Asked Questions
What kind of key does my Jeep Grand Cherokee use?
It depends on the year. A 2005 to 2007 Grand Cherokee uses a metal key with the remote built into the head. A 2008 to 2013 model uses a FOBIK, a plastic fob with no exposed blade that is pushed into a slot in the dash, with push-button start optional from 2011. A 2014 to 2021 model uses a proximity fob with push-button start as standard. All of them contain an immobilizer chip that has to be programmed to the vehicle.
How much does a Jeep Grand Cherokee key cost in Fort Worth?
As of October 2026, a 2005 to 2013 remote-head key or FOBIK runs $120 to $200 cut and programmed with a working key present. A 2014 to 2021 proximity fob runs $220 to $500. With no working key at all, expect $180 to $450. A second matching key made during the same visit is about $65.
What is a FOBIK?
FOBIK stands for fob-integrated key. It is the rectangular plastic fob Chrysler, Dodge and Jeep used from roughly 2008. Instead of a metal blade turning a lock cylinder, the nose of the fob is pushed into a slot called the Wireless Ignition Node and rotated like a key. A small metal emergency blade slides out of the fob body for the driver door.
Where is the FCC ID on a Grand Cherokee key?
On the back of the fob case in small molded or printed type. On FOBIK and proximity fobs it may also be inside, visible once the emergency blade is removed. It identifies the exact remote circuit and frequency, which makes it the most reliable way to match a replacement. Read it off your own key rather than trusting a listing that claims to fit many years.
Can I program a Jeep Grand Cherokee key myself?
On some earlier model years an owner with two working programmed keys can add a third using a sequence in the owner manual. With one key or none, and on proximity-fob model years generally, programming requires diagnostic equipment and a security PIN specific to the vehicle. The emergency blade also has to be cut. If a self-programming attempt does not work the first time, stop rather than repeating it.
Why does my 2018 or newer Grand Cherokee need extra steps to program a key?
From the 2018 model year, Chrysler-group vehicles including the Grand Cherokee have a secure gateway module that blocks unauthenticated diagnostic commands. A key cannot be programmed until the tool is authenticated to the vehicle through an authorized service or connected past the gateway. It adds a step to the job. It does not mean the vehicle has to go to a dealership.
Does this cover the 2022 and newer Grand Cherokee?
No. The redesigned Grand Cherokee and the three-row Grand Cherokee L use a different fob and a newer encrypted chip family from the 2014 to 2021 generation, and the parts do not interchange. If you have one of those, call with the year and we will confirm the correct fob from the FCC ID on yours.
