BMW Won’t Start | Key Symbol on Dashboard

A BMW may show the key symbol on the instrument cluster, the PARK light stays on, and the engine won’t start if the key is not recognized. The key may have a slash, line, or exclamation on top.

This problem is because BMW does not recognize the key, which could be due to several reasons. If BMW yellow key warning light displays when you are driving, it is because the car stopped recognizing the key in the cabin. This can be due to the key being physically removed from the car or a problem with comfort access.

Common Causes

  • Defective BMW key
  • Comfort access not working
  • Low battery voltage
  • Electrical interference
  • Water in BMW keyfob
  • Local radio waves

If your BMW key fob got wet because you washed it or let it out in the rain, it could fail to communicate with your BMW. Let the BMW key fob dry for a few hours and try again.

Even if the key starts to work again, you shouldn’t rely on it as it may stop working at any time.

Possible Solutions

Replace Key Fob Battery

Replace the batteries in your key fob. If you have comfort access, the batteries may be dead. If that is the case, your BMW will not recognize the comfort access key.

A temporary solution would be to start the car by inserting the key into the key slot, pressing the start button with the keyfob, or placing the keyfob next to the steering column while pressing start.

If your BMW has a Start/Stop button, you need to hold the key next to the steering column where you see a small key symbol. Some BMW models have a slot where you can insert the key for a manual start or press the key against the Stop/Start button.

Try the Spare Key

Try another key. There is a very good chance that the BMW key fob has failed. If you have a second key, try starting the car with it. The first key fob is defective if the car starts and runs fine with the other key.

Check Car Battery

Check the age of the main battery on your BMW.

If the battery is over 7 years old, replace it even if you think you don’t need a new battery. BMWs are very sensitive to the battery and voltage drops. A low battery can cause electrical issues, including the key not being recognized by the ignition.

Follow the guide on how to replace the BMW battery. Rember to perform battery registration as outlined in the tutorial.

Read Fault Codes
