Problem 1: Key Stuck in the Ignition

Key stuck is one of the most probable causes of an ignition switch problem. A stuck key does not allow the key to turn and fails to ensure contact between the electrical components to generate a spark for sparking the engine. You may be unable to remove the stuck key. A key can get stuck due to wear or tear.


  • Park your vehicle and engage the parking brake. Now, wear the gloves and disconnect the battery because you may be unable to switch off the ignition with a stuck key issue. 
  • Once the battery is disconnected, remove the steering column covers. For the lower column, you will need a screwdriver to loosen the screws.
  • Open the ignition switch; you will see the release pin or button holding the key. Gently press that pin; the key will release as you press the button.
  • Remove the key and inspect the key for physical damage. Also, check the ignition switch and ensure it is okay and adequately lubricated. Once all issues are fixed, insert the key and ensure the ignition switch works.

Problem 2: Dirt in the Ignition Switch

Poor maintenance causes dirt or moisture accumulation in the ignition switch. Over time, it causes corrosion or wear and tear. It also restricts the key to turning. If a key struggles to turn, you will experience issues starting your vehicle.


  • Disconnect your battery and ensure no power is flowing through electrical components.
  • Then, remove the columns and locate the ignition switch.
  • Inspect it for dirt or moisture. If there is dirt, remove it and use a cleaner to remove the corrosion. For ignition switch cleaning, I recommend NEIKO 53730A Portable Car Vacuum cleaner. It quickly removes stains, corrosion, and dust.
  • Once cleaned, reassemble all parts and test the ignition switch. Make sure the switch works fine.

Problem 3: Electrical Issues

Electrical issues such as loose connections, poor wiring, or broken or burnt wires can cause ignition switch issues in Chrysler 300.  Due to such problems, an ignition switch becomes erratic to start the engine properly.


  • Disconnect your car’s battery and remove the steering column covers. 
  • Now remove the ignition switch bolts and access the switch wiring harnesses.
  • First, check for burned or broken wires and repair them if needed.
  • Next, look for the correct connections and ensure the wires are connected to the power source.
  • Finally, check for loose connections and ensure no connection should be loose. If you see a connection is loose, tighten it.
  • Once done, reassemble the ignition switch and test to ensure the problem has been fixed.

Problem 4: Dead Battery

A dead car battery can cause ignition switch failure in the Chrysler 300. When a battery dies, there is no power to ignite the switch, which makes it hard to start the car. You will need to replace the dead battery to start the engine.


  • Before replacing your car battery, first ensure the battery is dead.
  • Open your car’s hood and disconnect the battery terminals.
  • Remove the battery and test it using a multimeter. Make sure you have a quality digital multimeter. I recommend AstroAI Digital Multimeter for your Chrysler 300.
  • Check the voltage; if the voltage is 12.4, the battery has no issue, but if the voltage is less, put the battery on recharge. Recheck it after half an hour if the voltage is 12.4 V; your battery has no issue. But if it is still low, your battery is dead.
  • Take a new battery and install it in your car. Once installed, connect its terminals and test the ignition switch. Make sure there is no issue.

Problem 5: Ignition Cylinder Problems

  • Now remove the ignition switch and look at its back; you will see the ignition cylinder.
