Porsche key flashing red? Here’s your answer to why this might be the case.
The LED on the key flashes red when the key is turned to the “on” or “start” position but does not start the car.
The Porsche key fob flashing red light is a warning to other drivers that the car is not actually started.
When you hold down the brake pedal and press the start button the light turns green and stays on until you release the brake pedal.
What Does The Red Light On My Key Fob Mean?
The red light usually means that the key fob is not communicating with the car.
One possible reason for this is that the battery in the key fob is low and needs to be replaced.
If you’re having trouble getting the key fob to communicate with your car you can try holding it closer to the car’s receiver or pointing it more directly at the receiver.
You can also try wiggling the key fob around a bit to see if that helps create a better connection.
How Do I Know If My Car Key Battery Is Dying?
Seriously if your car key battery is dying your car won’t start and you’ll know it.
The best way to prevent this from happening is to have the battery replaced when it still has some life left in it rather than waiting until it’s completely dead.
Batteries are relatively inexpensive so there’s no real reason to wait until it’s too late.
