Is it Okay to Leave the Key in the Run Position Without Starting the Car?

Leaving the key in the run position without starting the car is generally not recommended. While it may not damage the car immediately, it can lead to several issues:

  • Battery drain: Leaving the key in the run position continuously draws power from the battery, which can eventually drain it. This can lead to a dead battery and the inability to start the car.
  • Electrical system damage: In some cases, leaving the key in the run position can cause damage to the electrical system, particularly if there are any electrical faults present.
  • Fire hazard: In rare instances, leaving the key in the run position can potentially create a fire hazard if there is a fault in the ignition system or wiring.

Therefore, it is advisable to remove the key from the ignition when the car is not running. This helps preserve the battery, protects the electrical system, and minimizes the risk of fire.

  • What should I do if I left the key in the run position and the battery is dead? Call for roadside assistance or jump-start the car using another battery.
