Let’s discuss the most common reasons your Jeep Renegade won’t start. The more you know, the better you can handle troubles.

Dead Battery

One of the most common reasons for a Jeep Renegade failing to start is a dead battery.

They can’t last forever – eventually, the device may die, leaving you with a dead vehicle. The battery also may be weak, dying, or covered with corrosion.

It’s critical to test the battery first and examine it for any damage. If you notice issues with the battery, remove it or take it to a professional for additional assistance. If corrosion is the trouble, you can clean it off in a few simple steps. Remove the pole cables, unclamp the circuits, and remove the corrosion until the battery is in excellent condition.

Faulty Alternator

An alternator is a critical component in a Jeep Renegade. It creates electricity for the car, permitting it to move.

Without the alternator, the battery has no way to charge. The battery quickly runs out and results in a lack of movement from your Jeep Renegade. It’s rare for an alternator to break, especially with modern technology. However, it’s still possible.

Unfortunately, the only real solution to a faulty alternator is to remove the old one and invest in a new one for your Jeep Renegade. Alternators are more likely to break down the older they are, so take care if you have an older vehicle.

Issue With the Starter

Lastly, there could be trouble with the starter.

This motor works to kick your vehicle into action on the road. It has a limited lifespan like any part of a vehicle. If it’s used too much, it will eventually break down and prevent the engine from starting.

You can determine if a starter is at fault by the noises when the key turns. Rather than the comfortable rumble of the engine, you will hear multiple clicks. If the starter is troubled, you must purchase a new one and replace the broken starter.

How Do You Start a Jeep Renegade with a Dead Key?

The Jeep Renegade uses a key fob to start. This device makes it much easier to start your device, but there is a catch – the key fob can die. If you have a dead fob, is it possible to start your Jeep Renegade? Should you get a new one before you can drive again?

Here’s a quick walk-through video, with written steps below:

It isn’t too tricky to start a Jeep Renegade with a dead key. All you need to do is:

  1. Press the Start/Stop button with the top end of the fob
  2. Hit the brake
  3. Put pressure on the ignition

Your vehicle will be ready to go after this point.

Normally, you would press the ignition button with your finger. Using the base of the fob instead when the device is dead allows the ignition to locate the chip buried inside the fob. What if a dead fob is not the trouble? What if you need to jump-start the vehicle?

How Do I Jump Start My Jeep Renegade?

Sometimes, your Jeep Renegade might be in a state where it’s necessary to jump-start the vehicle. You can use another car or booster battery, along with jumper cables.

To jump-start the Renegade:

  1. Put on the Electric Parking Brake and put the car in Park
  2. Turn off electrical components, repeat with the other vehicle using one
  3. Connect the positive jumper end to the positive post of the car, then the same for the other vehicle or battery
  4. Attach the negative to the post in the car
  5. Add the other end of the negative to solid engine ground
  6. Start the engine in the helping car, wait, then turn on the other vehicle

It should start after this process.

It’s critical to remove the jewelry and to keep open flames away from the battery. Both could cause harm to you during the jumping process.

How Long Does a Jeep Renegade Battery Last?

A typical Jeep Renegade battery will last three to five years. Drivers should test the battery every once in a while to determine if the voltage is up to the proper standard.

The lifespan of a battery depends on factors like:

  • Battery size
  • Battery type
  • Weather conditions
  • Driving habits

Variations in these can decrease or increase battery life.

The way you drive has an impact on your battery. Sometimes, poor driving can cause a Jeep Renegade not to start.
