How to Program Key Fob Push Start Jeep Cherokee: Easy Guide

Many Jeep Cherokee owners enjoy the comfort and convenience of key fob push start systems. However, programming a new key fob or reprogramming an existing one can feel challenging, especially for beginners. This guide will walk you through the process step by step, using simple explanations, practical examples, and real data. Whether you lost your key, bought a new fob, or want a backup, you’ll learn how to get your Jeep Cherokee’s push start system working smoothly again.

Understanding Key Fob Push Start Systems

A key fob push start allows you to start your Jeep Cherokee by pressing a button, as long as the fob is inside the car. The fob uses radio signals to communicate with your vehicle’s computer, verifying that you have the right key. If the fob is not programmed, the car won’t start.

Why does programming matter?

• Security: Only authorized fobs can start your Jeep.
• Convenience: Lost or broken fobs can be replaced.
• Compatibility: Not all fobs work with all Cherokees.

Key Fob Types For Jeep Cherokee

There are several types of key fobs used in Jeep Cherokees, depending on the model year.

Tip: Always check your owner’s manual or look at your old fob to match the style before buying a replacement.

When Do You Need To Program A Key Fob?

Programming is needed in several situations:

• You bought a new or used fob.
• Your old fob is lost or broken.
• You want an extra fob for family.
• The battery was disconnected and fob lost memory (rare).

For security, programming erases old codes, so lost or stolen fobs won’t work.

Can You Program A Jeep Cherokee Key Fob Yourself?

This is a common question among owners. The answer depends on your Jeep’s year and features.

• 2014 and newer: Most require dealer or locksmith programming with special equipment.
• 2013 and older: Some can be programmed at home with steps in the owner’s manual.

Here’s a comparison of programming options:

Non-obvious insight: Even if you buy a “program-it-yourself” fob online, most 2014+ Jeep Cherokees still need special dealer tools.

Step-by-step: Programming A Push Start Key Fob (2014+ Jeep Cherokee)

If your Cherokee has push button start (2014 and newer), you usually need professional help. Here’s how the process works:

1. Buy The Right Key Fob

• Match your fob by part number (printed inside your old fob).
• Use only OEM or certified aftermarket fobs.
• Avoid very cheap online fobs—they often fail to program.

2. Gather Required Items

• Your Jeep Cherokee with all working fobs
• The new/unprogrammed fob
• Photo ID (for dealer/locksmith)
• Vehicle registration or proof of ownership

3. Visit A Dealer Or Automotive Locksmith

• Call ahead for price quotes.
• Some mobile locksmiths can come to your location.

4. The Programming Process

• The technician connects a diagnostic tool to your car’s OBD-II port.
• They access the car’s computer.
• Old codes are erased, and the new fob is paired.
• All existing fobs must be present, or they’ll stop working.

Example: Sarah lost her only fob for her 2017 Cherokee. The dealer erased all old keys and programmed two new ones for $180.

5. Test All Fobs

• Try locking/unlocking the doors.
• Start the Jeep by pressing the push button.
• If any fob doesn’t work, ask the technician to re-check programming.

Practical tip: Always program a backup fob. If you lose the only fob, towing and emergency programming costs are much higher.

Diy Programming For Older Jeep Cherokees

If you have a pre-2014 model, you might be able to program a new fob yourself.

What You Need

• 2 working, programmed key fobs (not just one)
• The new/unprogrammed fob

Diy Programming Steps

• Sit in the driver’s seat. Close all doors.
• Insert the first working key. Turn to “ON” (don’t start the engine). Wait 5 seconds. Turn off and remove.
• Within 10 seconds, insert the second working key. Turn to “ON,” wait, then turn off.
• Within 10 seconds, insert the new key. Turn to “ON.” After a few seconds, you’ll hear a chime. This means the new fob is programmed.

Non-obvious insight: If you don’t have two working fobs, DIY programming won’t work. You’ll need a dealer or locksmith.

Common Mistakes And How To Avoid Them

Many beginners make small errors that lead to wasted time or extra costs.

• Buying the wrong fob: Always match the FCC ID and part number.
• Trying to program a used fob: Most used fobs can’t be reprogrammed. Use only new or “virgin” fobs.
• Losing all fobs before programming: If you lose all, the process is more expensive and time-consuming.
• Not testing after programming: Always check every function (start, lock, unlock, panic) before leaving the dealer or locksmith.

What Does Programming Cost?

Programming prices depend on your Jeep’s year and your location.

• Dealer: $100–$200 for programming. Fob price is extra ($80–$250).
• Locksmith: $70–$180 for programming. Fobs may be cheaper.
• DIY: Free if you have two working fobs and an older Jeep.

Example: In Dallas, a 2020 Cherokee key fob costs about $120 on Amazon, and programming at a local locksmith is $95.

What To Do If All Key Fobs Are Lost

Losing all fobs is a stressful situation, but you have options.

• Call your local Jeep dealer or a certified locksmith.
• You may need to show your driver’s license and registration.
• Some Jeep models allow “emergency start” with a backup code, but most require programming.

Tip: Always keep a backup fob in a safe place outside your vehicle.

Security Considerations

Programming a new fob erases old codes. This protects you if a fob is stolen. Always make sure:

• Only trusted people have your backup fobs.
• Old fobs are disabled if lost or stolen.

Non-obvious insight: Some insurance policies cover lost key fobs or programming costs. Check your coverage.

How To Tell If Your Key Fob Needs Reprogramming

Sometimes, your fob may stop working even if the battery is good. Signs you may need to reprogram:

• The car doesn’t start or respond to the push button.
• Lock/unlock buttons don’t work.
• The fob works only sometimes.

Before reprogramming: Try replacing the battery and resetting the car’s electronics (disconnect battery for 5 minutes).

Key Fob Programming Vs. Cloning

There is a difference between programming and cloning:

• Programming: Registers a new fob to your Jeep’s computer. Only programmed fobs work.
• Cloning: Copies the signal from an old fob. Not secure and not recommended for push start systems.

Example: Some online sellers offer “cloned” fobs for less money. These often fail and can cause security problems.

Key Fob Battery Replacement

Sometimes, a fob works poorly because of a weak battery. Replacing the battery is simple and may solve your problem.

Steps:

• Open the fob case (use a small flat screwdriver).
• Remove the old battery (CR2032 for most Cherokees).
• Insert a new battery, matching the + and – sides.
• Snap the case shut and test all buttons.

Tip: If the fob still doesn’t work, programming is likely needed.

Troubleshooting Programming Problems

If you try to program a fob and it doesn’t work, check these points:

• Make sure the fob is new and matches your model.
• Confirm you have all working fobs present during programming.
• Ask the dealer to check for computer software updates.
• If a locksmith can’t program the fob, try the dealer (they have more advanced tools).

How To Save Money On Key Fob Programming

• Buy fobs online, but only from trusted sellers.
• Get price quotes from several dealers and locksmiths.
• Ask about discounts for programming multiple fobs at once.
• Check if your car insurance covers key loss.

Practical tip: Some Jeep forums and owner groups share discount codes or recommendations for local locksmiths.

Advanced Features: Remote Start, Panic, And More

Modern Jeep Cherokee fobs can control more than just locks and ignition.

Note: If your Cherokee doesn’t have a remote start system installed, the button will not work, even if the fob is programmed.

Real-world Example: Programming A 2019 Jeep Cherokee Key Fob

John bought a 2019 Jeep Cherokee with only one fob. He ordered a new OEM fob online for $110. A local locksmith programmed both fobs for $90. The process took 20 minutes.

Key points John learned:

• The locksmith needed both fobs during programming.
• All buttons worked after testing.
• He now keeps the backup fob at home.
