We all know keychain fobs are far from the most sophisticated devices in the world, but there’s a chance that their merely elementary security measures may put your car at risk. While it’s far from a widespread problem, it seems to be an issue most companies are willing to ignore.
A security expert has demonstrated that at least one popular immobilizer tool (which prevents your car from starting if you’re not nearby with the key) could be bypassed in just six hours.
