Electric vehicle immobiliser UK — relay safe
Tesla, BMW i-series, Nissan Leaf, Hyundai Kona, Volkswagen ID.4. Relay immobilisers operating on the 12V auxiliary system — independent of the high-voltage drivetrain.
EVs are increasingly targeted by relay attacks — especially Tesla models and premium EVs in high-density urban areas. CAN bus immobilisers on EVs carry amplified risk due to the more complex and tightly controlled ECU architecture. LockCar relay products operate on the 12V auxiliary system and have no contact with the high-voltage network or EV-specific CAN bus.
The 12V auxiliary system in any EV controls ancillary functions — including, on most models, auxiliary relay circuits that LockCar products interrupt to prevent engine start. This means the same relay principle that works on a petrol car works on an EV — without any contact with the high-voltage battery management system or the EV’s complex power network.
