Original Trunk lock

A Trunk Lock for a Tesla is a security and latching mechanism designed to securely keep the trunk or frunk closed. It is typically an electronic actuator integrated with the vehicle's central locking system. When activated, it either engages or releases a physical bolt or hook, preventing the trunk from being opened without authorization. This component is crucial for both security—preventing unauthorized access to the trunk compartment—and safety—ensuring the trunk remains closed while the vehicle is in motion. On Teslas, the trunk lock works in conjunction with sensors and software to provide status updates to the driver via the touchscreen or mobile app. Issues with the lock can lead to error messages, inability to open/close the trunk, or compromised security.
