Locks that use Bluetooth Low Energy to authenticate keys are vulnerable to remote unlocking.
The research focused on Teslas, but the exploit is generalizable.
In a video shared with Reuters, NCC Group researcher Sultan Qasim Khan was able to open and then drive a Tesla using a small relay device attached to a laptop which bridged a large gap between the Tesla and the Tesla owner's phone.
"This proves that any product relying on a trusted BLE connection is vulnerable to attacks even from the other side of the world," the UK-based firm said in a statement, referring to the Bluetooth Low Energy protocol-technology used in millions of cars and smart locks which automatically open when in close proximity to an authorised device.
Although Khan demonstrated the hack on a 2021 Tesla Model Y, NCC Group said any smart locks using BLE technology, including residential smart locks, could be unlocked in the same way.
