Best car trackers for Audi UK 2025, GPS tracking with physical theft prevention

Audi Q5, Q7, A6, and RS models with Advanced Key passive entry are relay theft targets across the UK. The best Audi car tracker combines real-time 4G GPS tracking with a hardwired relay immobiliser that stops theft at the source rather than tracking the vehicle after it has been stolen. LockCar One Plus delivers both functions in one UK-manufactured, professionally installed system.

Advanced Key relay vulnerability on Audi models

Audi Advanced Key, fitted as standard on Q5, Q7, A6, A8, e-tron, and most current Audi models, uses passive RF challenge-response authentication that relay equipment can extend artificially. A criminal pair with relay amplifier and receiver can unlock and start an Advanced Key Audi from a driveway in under 60 seconds, leaving no evidence of forced entry.

The Advanced Key system does not distinguish between a genuine proximate key and an amplified distant key. The factory immobiliser, which is part of the Advanced Key system, is satisfied by the relayed signal exactly as it would be by a legitimate key. LockCar adds an independent physical relay break that remains open until a separate encrypted authentication is provided.

LockCar One Plus for Audi, full specification

The LockCar One Plus provides a 20A hardwired relay break in the Audi start circuit, AES-128 encrypted proximity tag and app authentication, 4G GPS tracking with real-time location updates, a forward-facing live camera stream accessible from the LockCar app, movement alerts pushed immediately to your phone if the vehicle moves unexpectedly, and remote immobilisation capability from anywhere with a mobile data connection.

Installation follows Audi-specific procedures and does not interact with MMI infotainment, Audi connect, or any Audi software system. Installation typically takes 60 to 90 minutes at your location.
