Experiencing issues with your 2022 Jeep Wrangler key fob can be frustrating, especially when you’re on the go. A dead key fob battery is a common culprit, but thankfully, it doesn’t mean you’re stranded. This guide will walk you through troubleshooting steps and solutions to get you back on the road, even if your key fob battery fails.
Starting Your 2022 Jeep Wrangler with a Dead Key Fob Battery
Just like many modern vehicles, your 2022 Jeep Wrangler is equipped with a feature that allows you to start the engine even when the key fob battery is dead. Here’s how to do it:
-
Unlock the Door Manually: Use the physical key inside your key fob to unlock the driver’s side door. Be prepared for the alarm to sound if it’s activated.
-
Position the Key Fob: Enter your Jeep Wrangler and immediately move to silence the alarm. Take your key fob and locate the side with the emergency key slot (typically the end opposite the key ring).
-
Press the Start Button with the Key Fob: Firmly press the start/stop ignition button with the angled side of your key fob. Hold it there for a moment while you also press the brake pedal.
-
Start the Engine: With the key fob pressed against the start button and the brake pedal engaged, press the start button again as you normally would to start your Jeep Wrangler. The vehicle should recognize the key fob’s transponder even without battery power and start the engine.
This procedure utilizes the key fob’s passive RFID chip, which doesn’t require battery power to communicate with your Jeep’s ignition system at close range.
What to Do if Your 2022 Jeep Wrangler Key Fob Gets Wet
Water damage is another common issue that can temporarily disable your key fob. If your 2022 Jeep Wrangler key fob gets wet, follow these steps:
-
Retrieve and Dry Immediately: Get the key fob out of the water as quickly as possible.
-
Open the Key Fob: Most Jeep Wrangler key fobs can be carefully opened. You’ll likely need a small Phillips head screwdriver to remove a tiny screw, often located on the back of the fob.
-
Remove the Battery: Once open, carefully remove the battery from the key fob.
-
Rinse with Fresh Water (If Necessary): If the fob was exposed to salt water, rinse all parts (including the battery compartment and circuit board, if accessible) with fresh water to prevent corrosion.
-
Dry Thoroughly: Let all components of the key fob air dry completely. You can gently use compressed air or a soft cloth to aid in drying, ensuring no moisture remains before reassembly.
-
Reassemble and Test: Once everything is dry, reinsert the battery, carefully reassemble the key fob, and test its functionality.

Preventing 2022 Jeep Wrangler Key Fob Battery Issues
To minimize the chances of being caught off guard by a dead key fob battery in your 2022 Jeep Wrangler, consider these preventative measures:
-
Regular Battery Replacement: Key fob batteries typically last for 2-3 years. Consider replacing the battery proactively every two years to avoid unexpected failures. The 2022 Jeep Wrangler key fob usually uses a CR2032 battery, which is widely available.
-
Spare Key Fob Battery: Keep a spare CR2032 battery in your glove compartment or wallet, so you’re prepared for a quick battery swap on the go.
-
Protect from Water and Extreme Temperatures: Avoid exposing your key fob to excessive moisture or extreme heat or cold, as these conditions can shorten battery life and damage the electronics.
When to Seek Professional Help
While these troubleshooting steps can resolve many common key fob issues, there are situations where professional assistance is necessary:
-
Electronic Malfunction: If your key fob still doesn’t work after replacing the battery and drying it out, there may be an electronic malfunction within the fob itself.
-
Lost or Damaged Key Fob: If you lose your key fob or it’s severely damaged, you’ll need to get a replacement.
-
Immobilizer Issues: In rare cases, starting problems might stem from issues with your Jeep Wrangler’s immobilizer system, requiring dealer or locksmith intervention.
For key fob replacements, programming, or more complex electronic issues, contacting a qualified locksmith specializing in automotive keys or your local Jeep dealership is recommended. They have the tools and expertise to diagnose and resolve more intricate key fob problems for your 2022 Jeep Wrangler.
