2014-2023 Jeep Cherokee Push-Button Ignition Switch: No-Start Problems and Replacement Guide
This guide explains common failures of the push-to-start button in the 2014-2023 Jeep Cherokee, and clarifies the critical question of whether it needs programming (it doesn't).
- The ignition switch (push-button) itself DOES NOT require programming; it is a simple plug-and-play part.
- Failure is often intermittent, with the engine refusing to crank despite the dash lights turning on. Multiple presses may be required to start.
- Before replacing the switch, rule out simpler issues like a weak car battery, a dead key fob battery, or a faulty brake pedal switch.
- A used OEM switch is a reliable and cost-effective alternative to a new aftermarket part, as it guarantees fit and function without programming hassles.
Symptoms of a Failing Ignition Switch
A faulty push-to-start button on a Jeep Cherokee can cause frustrating and often intermittent issues. Because it's part of a complex system, symptoms can sometimes be confused with other problems like a weak battery or a bad key fob.
- No Start or Intermittent Start: The most common symptom is pressing the button and having nothing happen. The dashboard lights may turn on, but the engine does not crank. This may happen intermittently, sometimes working after multiple presses.
- Vehicle Enters Accessory Mode Only: You may find that pressing the button only turns on the radio and other accessories, but it refuses to engage the starter to turn the engine over.
- Delayed Start: After pressing the button, there might be a noticeable delay before the engine begins to crank.
- "Key Not Detected" Message: While often related to the key fob battery or other system antennas, a failing switch can sometimes contribute to communication errors within the keyless system.
- Backlight Failure: The LED illumination on the button may flicker or fail completely, making it difficult to see in the dark. This does not typically affect the switch's function but indicates internal electronic failure is imminent. 🎬 Watch this step-by-step guide to fixing a non-working push button.
It's important to rule out other causes first, such as a dead battery in the vehicle or the key fob, a faulty brake pedal switch, or a bad starter motor before condemning the ignition switch.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
While there are no widespread recalls specifically for the push-button ignition switch itself, owners of these vehicles should be aware of related issues.
Important Safety Recall: Power Liftgate Module Fire Risk
Warning: Chrysler issued a major recall for 2014-2016 Jeep Cherokee models due to a fire risk from the power liftgate module. An electrical short can cause a fire, even with the ignition turned off. Owners are advised to park their vehicles outside and away from structures until the recall repair is performed. You can check if your vehicle is affected by entering your VIN on the NHTSA website.
Technical Service Bulletins (TSBs)
While TSBs don't always point to a faulty part, they show areas the manufacturer has identified for potential issues. A relevant TSB for the 2016 Cherokee is S2008000013, which addresses issues with "Key Programming, Security Pin Request, Pin Invalid." This highlights the complexity of the vehicle's security system, which can sometimes be misdiagnosed as a simple switch failure.
Associated OBD-II Trouble Codes
A failing ignition switch itself may not set a specific code. However, problems in the starting and security system will. A professional scan tool may find:
- P0513 - Invalid Immobilizer Key: This code is set when the vehicle's immobilizer system does not recognize the key fob, which can be a symptom of a broader system fault.
- U-Series Codes (Communication Codes): Faults like U11E9 may be present if there are communication breakdowns between the various modules involved in the starting sequence.
Pro Tip: The ignition switch can be removed by prying it out of the dash. If your vehicle won't start with the button, you can often pop the button out and insert the key fob directly into the underlying slot to start the vehicle manually. This is a useful emergency bypass.

This is one of the best parts to buy used. Because the switch itself does not require programming, a used OEM unit offers significant savings with very low risk.
- No Programming Needed: The most important fact is that the push-button switch is a simple plug-and-play component. You do not need a dealer or locksmith to program it. The vehicle's security information is stored in the RF Hub and Body Control Module (BCM), not the button.
- Why Used OEM is a Smart Choice: A used OEM switch from a reputable supplier is preferable to a new aftermarket part. It guarantees perfect fitment and electrical compatibility. Some aftermarket switches can have slight differences that cause connection issues or premature failure.
- What to Inspect: When buying a used switch, visually inspect the electrical connector pins to ensure they are straight and free of corrosion. Check that the button has a firm, tactile click and isn't loose or mushy. Ensure the plastic housing and retaining clips are not cracked or broken.
- Part Number Verification: Match the part number if possible, but know that many numbers supersede. The most recent part number, 6CK47DX9AC, replaces several older versions like 1VB70DX9AA, 1VB70DX9AB, and others.
Cost of Replacement
Replacing the ignition switch is relatively inexpensive, especially if you do it yourself.
| Part Type | Estimated Cost |

| New OEM (Mopar) | $105 - $165 |
| New Aftermarket | $40 - $80 |
| Used OEM | $35 - $55 |
| Shop Labor Cost | $130 - $250 |
Frequently Asked Questions (FAQ)
Does a replacement ignition switch for a 2014-2023 Jeep Cherokee need to be programmed?
No. The push-button switch itself is a simple electrical component and does not store any security data. It is a plug-and-play replacement. The vehicle's security and key fob information are stored in other modules.
Can I replace the Jeep Cherokee ignition switch myself?
Yes, this is a relatively easy DIY repair. It typically involves carefully prying off the surrounding dash trim (often the climate control panel), removing a few screws, disconnecting the electrical connector, and swapping the switch. The entire process can usually be done in under 30 minutes with basic tools.
🎬 Watch a complete walkthrough of the ignition switch replacement process.My Jeep won't start. How do I know if it's the ignition switch?
First, check the simple things. Is the vehicle battery charged? Is the battery in your key fob good? Are you pressing the brake pedal firmly when pushing the start button? If all those are fine and the vehicle intermittently fails to crank or only enters accessory mode, the switch is a likely culprit, especially if you've had it happen more than once.
What's the difference between the ignition switch and the ignition lock cylinder?
This part, the push-button switch, is for keyless ignition models. An ignition lock cylinder is the part you would insert and turn a traditional metal key in. The 2014-2023 Cherokee uses one or the other; they are not interchangeable. This guide and these part numbers are only for the push-button start models.
