Mercedes GPS Trackers & Immobilisers — Insurance-Approved Security

Mercedes-Benz vehicles are among the most frequently targeted by relay thieves in the UK. Keyless-entry models including the C-Class, E-Class, S-Class, GLC, GLE, and G-Wagen are particularly vulnerable. LockCar provides professional GPS tracker and immobiliser installation to protect your Mercedes against modern theft methods.

Mercedes theft vulnerabilities

Most modern Mercedes use keyless entry (Keyless-Go) which is vulnerable to relay amplification attacks. Thieves can capture your key fob’s signal from inside your house and start your car in under 60 seconds. A physical relay immobiliser — like LockCar’s relay cut — stops this attack completely because it does not rely on key fob signals. Mercedes owners in London, Birmingham, Manchester, and Essex have reported high rates of relay theft.

Compatibility with Mercedes models

LockCar devices are compatible with all Mercedes-Benz models: A-Class, C-Class (W205/W206), E-Class (W213/W214), S-Class (W222/W223), GLC, GLE, GLS, G-Wagen, CLA, CLS, EQ electric range, and AMG variants. Professional installation ensures no interference with Mercedes electronics or warranty.
