Using Your Key Card to Unlock Your Tesla
This is usually the first thing people think of, and for good reason. The Tesla key card is your backup in these situations. The target of this section is to show readers how to use their Key Card as a reliable method of unlocking their vehicle when the main battery has died. This will give our readers a quick and simple method to gain access to their vehicle. A few years back, I was leaving a remote hiking trail when I encountered this exact scenario. My phone, which I normally used as my key, was also dead! Luckily, I remembered I had stashed my key card in my wallet. I frantically searched for the B-pillar (the pillar between the front and rear doors), eventually finding the sweet spot where the card reader was located. To my relief, the car unlocked. It was a huge relief, and I learned a valuable lesson that day: always keep your key card handy. Here's how it works: Locate the B-pillar on the driver's side of your Tesla. This is the vertical pillar between the front and rear doors. Hold your key card flat against the B-pillar, near the door handle, and wait for the car to recognize it. The car should unlock. If it doesn't work on the first try, try repositioning the card slightly. Sometimes it takes a few attempts to find the correct spot. Once the car is unlocked, you can open the door and get inside. Keep in mind that using the key card only unlocks the door; it won't start the car if the main battery is dead. You'll still need to jump-start the 12V battery to get the car running. This method is a lifesaver in a pinch and ensures you're never completely locked out of your vehicle.
Jump Starting Your Tesla's 12V Battery
This method is a little more involved but necessary if you need to actually drive the car. The target audience for this section of the article is the reader that needs to revive their Tesla back to a state where it is drivable.

The 12V battery in a Tesla is responsible for powering the car's electronics, including the door locks, lights, and computer system. When this battery dies, the car becomes unresponsive. To jump-start it, you'll need jumper cables and another car or a portable jump starter. First, locate the 12V battery in your Tesla. Depending on the model, it's usually located under the hood or in the frunk (front trunk). Consult your owner's manual for the exact location. Once you've found the battery, connect the red (positive) jumper cable to the positive terminal of the Tesla's 12V battery. Then, connect the other end of the red cable to the positive terminal of the donor car's battery. Next, connect the black (negative) jumper cable to the negative terminal of the donor car's battery. Finally, connect the other end of the black cable to a grounded metal surface on the Tesla, away from the battery. Start the donor car and let it run for a few minutes. Then, try starting your Tesla. If it starts, let it run for a while to allow the 12V battery to recharge. Disconnect the jumper cables in the reverse order that you connected them. Remember to consult your Tesla's owner's manual for specific instructions and safety precautions before attempting to jump-start the 12V battery. It’s a good idea to watch a video tutorial specific to your Tesla model if you’ve never done this before. This will help you visualize the steps and avoid making any mistakes.
