How To Program Key Fob For Jeep Grand Cherokee – With Push Button Start

by

Programming a key fob for your Jeep Grand Cherokee usually starts with sitting inside and closing all doors. If you’ve lost a fob or need a spare, learning how to program key fob for Jeep Grand Cherokee models can save you a trip to the dealership. This guide covers the most common methods for different model years, from 2005 to 2023.

You don’t need special tools for most procedures. Just follow the steps carefully. Some newer models may require a scan tool, but we’ll cover those cases too.

How To Program Key Fob For Jeep Grand Cherokee

Before you start, make sure you have a working key fob and a blank fob that matches your vehicle’s frequency. Check your owner’s manual for the correct part number. Most Grand Cherokees use a 433 MHz or 315 MHz frequency.

Here’s what you’ll need:

  • Your Jeep Grand Cherokee
  • All existing key fobs
  • The new unprogrammed fob
  • Patience and about 10 minutes

Method 1: Programming For 2005-2010 Jeep Grand Cherokee (WK)

These models use a simple sequence. No special tools required. The process involves turning the ignition on and off in a specific pattern.

  1. Sit in the driver’s seat with all doors closed.
  2. Insert the key into the ignition.
  3. Turn the key to the ON position (not start) and back to OFF quickly. Do this 5 times within 10 seconds.
  4. You should hear a chime or see the dash lights flash. This means the system is in programming mode.
  5. Press and hold the LOCK button on the new fob for 5 seconds.
  6. Release the LOCK button, then press and hold the UNLOCK button for 5 seconds.
  7. Repeat step 5 and 6 for any additional fobs you want to program.
  8. Turn the ignition to ON and then OFF to exit programming mode.
  9. Test all fobs by pressing LOCK and UNLOCK.

If the chime doesn’t sound, try again. Make sure you’re turning the key fast enough. Some users report needing to do the 5-turn sequence within 7 seconds.

Method 2: Programming For 2011-2013 Jeep Grand Cherokee (WK2)

These models have a slightly different procedure. You’ll use the ignition and door locks instead of the fob buttons.

  1. Close all doors and sit in the driver’s seat.
  2. Insert the key into the ignition.
  3. Turn the key to the ON position (not start) and back to OFF. Do this 4 times within 10 seconds.
  4. You should hear a chime. The system is now in programming mode.
  5. Press the LOCK button on the driver’s door panel.
  6. Press the UNLOCK button on the driver’s door panel.
  7. Press the LOCK button on the new fob.
  8. Press the UNLOCK button on the new fob.
  9. Repeat steps 5-8 for each additional fob.
  10. Turn the ignition to ON and then OFF to exit.
  11. Test all fobs.

This method works for most 2011-2013 models. If your Jeep has push-button start, skip to Method 4.

Method 3: Programming For 2014-2018 Jeep Grand Cherokee (WK2 With Keyless Entry)

These models often have keyless entry and push-button start. The process is different. You’ll need two working fobs to program a third one.

  1. Close all doors and sit in the driver’s seat.
  2. Place the first working fob in the center console cup holder.
  3. Press the START/STOP button once (do not start the engine).
  4. Remove the first fob and place the second working fob in the cup holder.
  5. Press the START/STOP button once.
  6. The dash should display “Key Fob Programming” or a similar message.
  7. Place the new unprogrammed fob in the cup holder.
  8. Press the START/STOP button once.
  9. The dash will confirm programming is complete.
  10. Test the new fob.

If you only have one working fob, you may need a dealer or locksmith. This method requires at least two programmed fobs to add a third.

Method 4: Programming For 2019-2023 Jeep Grand Cherokee (WL And WK2)

Newer models use a similar cup holder method but with some variations. The system is more sensitive to timing.

  1. Close all doors and sit in the driver’s seat.
  2. Place the first working fob in the center console cup holder (the one with the key icon).
  3. Press the ENGINE START/STOP button once without pressing the brake.
  4. Wait 10 seconds, then remove the first fob.
  5. Place the second working fob in the cup holder.
  6. Press the ENGINE START/STOP button once.
  7. Wait 10 seconds, then remove the second fob.
  8. Place the new fob in the cup holder.
  9. Press the ENGINE START/STOP button once.
  10. The dash will show “Key Fob Programmed” or flash a confirmation.
  11. Test all fobs.

Some 2021+ models require a dealer visit if you don’t have two working fobs. Check your owner’s manual for specifics.

Method 5: Using A Scan Tool For All Models

If the manual methods don’t work, you can use a diagnostic scan tool. This is common for 2014+ models or when you have zero working fobs.

  1. Purchase or borrow a compatible scan tool (like Autel or Foxwell).
  2. Connect the tool to the OBD-II port under the dashboard.
  3. Select “Key Programming” or “Immobilizer” from the menu.
  4. Follow the on-screen prompts. You’ll usually need to enter a security code (found in your owner’s manual or from the dealer).
  5. Place the new fob in the cup holder or near the steering column as instructed.
  6. The tool will program the fob. This takes about 2-5 minutes.
  7. Disconnect the tool and test the fob.

Scan tools range from $50 to $500. Cheaper ones may not work for all models. Consider renting one from an auto parts store.

Common Issues And Troubleshooting

Sometimes programming fails. Here are common problems and fixes.

No Chime Or Response

  • Make sure all doors are closed tightly.
  • Check the battery in the fob. Replace it if low.
  • Try a different key. Some ignitions wear out.
  • Ensure you’re turning the key fast enough. Count the turns out loud.

Fob Programs But Doesn’t Work

  • The fob may be incompatible. Check the part number.
  • The battery might be dead. Replace it even if it looks new.
  • The vehicle’s receiver may be faulty. This requires dealer diagnosis.

Only One Fob Works After Programming

  • You may have skipped a step. Repeat the process with all fobs.
  • Some systems require all fobs to be programmed at once. Don’t skip any.

Push-Button Start Not Responding

  • Place the fob directly on the START/STOP button. Some models read the fob this way.
  • Check the fob battery again. Low battery affects proximity sensing.

When To Call A Professional

Not all situations are DIY-friendly. Call a dealer or locksmith if:

  • You have zero working fobs for a 2014+ model.
  • The manual method fails after 3 attempts.
  • Your Jeep has a aftermarket security system.
  • You need a key cut as well as programmed.
  • The scan tool method doesn’t work.

Dealer prices range from $100 to $200 for programming. Locksmiths are often cheaper, around $50 to $150. Some mobile locksmiths come to you.

Tips For Buying A Replacement Fob

Not all fobs are equal. Here’s what to look for.

  • Buy from a reputable source. Amazon and eBay have many fakes.
  • Check the FCC ID on the back of your old fob. Match it exactly.
  • Some fobs need to be cut by a locksmith. Others come pre-cut.
  • Consider buying a pre-programmed fob from a specialist. They mail it ready to use.
  • Always buy at least two fobs. Programming is easier with a spare.

Frequently Asked Questions

Can I program a used fob from another Jeep?

Yes, but it must be erased first. Used fobs retain previous programming. You’ll need a scan tool or dealer to clear it. Some models allow overwriting, but not all.

DIY costs nothing if you have the fob. Dealer programming is $100-$200. Locksmiths charge $50-$150. Scan tool rental is $30-$60.

Why won’t my Jeep Grand Cherokee recognize my key fob?

Common causes: dead fob battery, incompatible fob, faulty receiver, or incorrect programming. Start with a new battery and try reprogramming.

Can I program a key fob without a working fob?

For older models (2005-2013), yes, using the ignition method. For 2014+ models, you usually need at least one working fob. Some require two.

Manual methods take 5-10 minutes. Scan tool methods take 10-20 minutes. Dealer visits take 30 minutes to an hour including wait time.

Final Thoughts

Programming a key fob for your Jeep Grand Cherokee is doable at home for most models. The key is knowing your model year and following the exact steps. If you get stuck, don’t force it. A professional can help without damaging your vehicle’s electronics.

Always test all functions after programming: lock, unlock, panic, and remote start if equipped. If something feels off, reprogram again. Sometimes the first attempt doesn’t sync properly.

Keep your new fob safe. Consider buying a silicone cover to protect it. And always have a spare programmed fob handy. It saves time and money in the long run.
