If it's a conventional folding key, you can directly use the mechanical key to open the door when the battery is dead. You can enter the car by opening either the door or the trunk, then lift the hood to perform external charging.

I remember that time when my Tesla Model 3 ran out of battery – it was nerve-wracking! But later I learned the manual door opening method: there's a small door handle under the front door handle. Gently push it to pop out the mechanical handle, then pull it hard to open the door. For Model S or X, look for the button on the edge of the door handle and press it to operate. The trunk also has an emergency release loop – you can find it in the bottom corner inside the car. Prevention is key. A dead 12V battery can paralyze all electronic systems, so it's advisable to regularly check the health of your car battery. Carry a physical key card or ensure the mobile app is functional. Develop a habit of charging before driving, especially during trips – don't let the battery level drop too low. Otherwise, stopping midway would be a hassle, affecting both safety and convenience.

As a daily driver, running out of power in a Tesla can be really nerve-wracking. I found that the door-opening procedure is quite simple: look for a small hole or button near the door, usually designed in a hidden black style. Press or pry it open to pop out the mechanical handle, then pull the door open with force. Don't forget there's a red pull cord in the trunk—give it a tug to gain access. Prevention is key: always download the Tesla App and set up a backup key. Sometimes, the app's remote door unlock feature works. A power bank can temporarily power the 12V small battery to try unlocking the doors. Safety first—avoid forcing anything open to prevent damaging the car's paint. Remember the location of the instructions in the manual for emergencies. Regularly checking the battery's lifespan reduces unexpected incidents, which is much more cost-effective and hassle-free than repairs.

From a mechanical perspective, Tesla door locks rely on the 12V auxiliary battery for power. When the battery is depleted, the electronic system fails, but each model has a hidden manual backup: for Model 3, press the small cover on the front handle to pry it open and pull the door; for Model S/X, press the button on the side of the handle. Mechanical unlocking avoids damage to the circuit. Preventive maintenance includes regularly testing the small battery voltage to keep it above 12.5V. When traveling, carry an emergency key card or a charger for quick charging to restore partial power.
