UC San Diego researchers discovered that 2.2 million vehicles fitted with KARR-SWDS aftermarket anti-theft devices—installed by dealerships at Honda, Toyota, Mazda, Ford, and Jeep—share a single encryption key, allowing remote Bluetooth attacks from up to five yards away to unlock doors and disable engines. Manufacturer Acrisure released a patch on 20 July 2026, but many car owners remain unaware their vehicles are vulnerable.

You've just found the playbook for the next wave of car theft—and 2.2 million vehicles are running the same unpatched code. If you build anti-theft software, remote access, or vehicle telematics, this shared-key architecture is your competition's collapse; if you're selling to dealerships, your customers now need to retrofit or face liability.
