Jump-starting the battery
Most people keep a set of jumper cables in their trunk for emergencies, but jumping a battery on modern cars might not be the most efficient option.

Attach the other end of the black cable to a clean, unpainted metal surface underneath the vehicle's hood. An engine block is an ideal choice.

Keys that are claimed-new purchased from third-party sellers won't work and are almost guaranteed to fail in the most critical moment.
Most locksmiths can't help you if you have only one working key and the dealer will charge high prices to replace the computer in your vehicle to make a new replacement.
