Answer 1
No, the key won't affect what you are experiencing. Sounds like you have a vehicle battery that is not fully charged, or some connections that are suspect. Check for voltage of the battery (12.5 or above), check to see if it survives a load test. Then, check all cables at all ends from your battery onwards to make sure everything is secure and clear of corrosion. -
