Most electric vehicles have electronic door release mechanisms that need power to work properly. In the event of a dead low-voltage battery, gaining access to the inside of the vehicle can be challenging. However, manufacturers have incorporated backup mechanical handles in their vehicles to allow users to open the doors from the inside with no power. It is important to familiarize yourself with the location of these mechanical releases in your specific vehicle, as they can vary from model to model. In some cases, people have become trapped inside EVs with electronic latches, such as Teslas, after losing power, but all vehicles with electric door latches have a mechanical override for emergency situations.
In one particular incident involving a Tesla Model Y in 2021, the driver became trapped inside the vehicle as it caught fire and lost power. Not knowing about the backup mechanical door handles, the driver resorted to breaking a window to escape. It is crucial to be aware of the location and functioning of the mechanical door release mechanisms in your EV to ensure a safe and quick escape in emergencies. Different EV models have varying procedures for manually unlatching the doors, with some requiring the removal of certain components to access the release mechanisms. Manufacturers have recognized the importance of these safety features and have made efforts to ensure that all vehicles with electric latches have a mechanical override option.
In the event of a dead low-voltage battery preventing access to an EV with powered latches, the situation can become challenging. Emergency services have been summoned to rescue individuals, such as a child trapped inside a Tesla Model Y when the exterior door handles stopped working. Some vehicles, like early Cadillac Lyriqs or Teslas, do not have a mechanical option for opening the doors. In such cases, charging the 12-volt battery, which powers the auxiliary systems including the door latches, becomes necessary to regain access to the vehicle. Accessing the 12-volt battery in a Tesla can vary depending on the model year, with newer models offering easier access to the terminals for charging. Similarly, other EVs may require accessing the battery terminals through various methods in order to charge the low-voltage battery and open the doors.
Charging the 12-volt battery in a Tesla Model 3, Model Y, Ford Mustang Mach-E, or other EVs with powered latches typically involves locating the terminals, which are often found behind covers or components on the front of the vehicle. By gaining access to the terminals and hooking them up to a charger, the low-voltage battery can be charged, and access to the vehicle restored. Legacy OEM EVs may also come equipped with a physical key that can be used to manually open the driver’s door and gain access to the vehicle for charging the battery. Ensuring that you know the location and procedure for accessing and charging the 12-volt battery in your EV can prove crucial in case of emergencies where power to the door latches is unavailable. By being prepared and informed, you can effectively navigate emergency situations and ensure your safety and that of your passengers.
