Causes of Jeep Wrangler Ignition Switch Problems
Your Jeep Wrangler ignition switch can have problems for several reasons. However, for ease, I have listed a few major causes that may help you diagnose and fix the issue quickly.
- Broken switch
- Low or dead battery
- Key Damage
- Ignition Cylinder Issues
- Wiring Problems
Jeep Wrangler Ignition Switch Problems and Solutions
Problem 1: Broken Ignition Switch
The ignition Switch delivers power to the engine for a smooth start. If broken, it will disrupt the electrical connection, and the circuit may break. It can prevent your key from turning and starting the engine.
- First of all, park your Jeep in a safe place and switch off its engine.
- Now, it opens its hood and locates its battery.
- Disconnect the battery terminals and ensure no power is delivered.
- Then, remove the steering column cover and look for the ignition switch.
- First, disconnect its wires and then remove its bolts to remove the switch.
- Remove the ignition switch and check it to ensure there is no fault. If the switch is broken, you will need a replacement. For the Jeep Wrangler, I recommend the STANDARD IGN Ignition Switch.
- Mount the new switch in its place and ensure it is appropriately secure.
- Reassemble the steering cover, reconnect the battery terminals, and check the ignition switch. Make sure the problem has been removed.
Problem 2: Low or Dead Battery
A low or dead battery can be the culprit for ignition switch issues on your Jeep Wrangler. It will fail to supply enough power to the ignition switch to ignite the switch for the engine to start.
- Open your Jeep’s hood and locate the battery.
- Remove battery terminals and take the Battery out of the compartment.
- Now, connect it to a digital multimeter. I recommend Innova multimeter for accurate readings. Check the readings on the screen and ensure they are 12.4V.
- If it is low, recharge the battery for at least half an hour and recheck the voltage. If it is 12.4, then it is okay. Otherwise, replace the battery.
- Take the new battery and mount it in its compartment.
Problem 3: Key Damage
If your Jeep Wrangler’s key is broken or bent, it may also make you unable to start the engine via the ignition switch. You may fail to turn the key properly to start the engine.
- First, check your key and ensure it is not broken or bent. If the key is okay, apply some lubricant to it and insert it into the ignition switch to start the engine.
- However, if the key is broken, you will need another key to start. First, look for a duplicate key.
- But if you don’t have a duplicate key, then go to a professional locksmith for a duplicate key. You can also visit the Jeep Wrangler’s dealership to fix the broken key issue.
- Once you get a duplicate one, ensure the ignition switch has no issue.
Problem 4: Ignition Cylinder Issues
The ignition cylinder helps engage the sequence for engine start. If the cylinder is damaged, it will fail to engage the sequence. Ultimately, you cannot start the engine.
- Look for the ignition switch cylinder, usually mounted near the steering column.
- then disconnect the battery and remove the steering column cover.
- Then, insert the key and turn the key to “ON.” Take a small pin and press the release button near the ignition cylinder.
- Now that the ignition cylinder is free pull out the cylinder and install the new cylinder. Make sure you have aligned it properly.
- Reassemble the steering column cover, and then reconnect the battery.
- Test the ignition switch and ensure it is okay.

Problem 5: Wiring Problems
Loose connections are also the reason for damaged circuits. If the connections are loose, you may be unable to ignite the engine.
- Remove the steering column cover and access the ignition switch.
- Locate its connected wires and ensure there are no broken or loose connections.
- If the wires are broken, replace them. If connections are loose, tighten them.
- Once the wires are replaced or connections tightened, test the switch and ensure the issue has been removed.
