Car Trackers for Electric Cars – EV-Compatible Security

Electric vehicles are increasingly targeted by thieves, particularly premium models like Tesla, BMW i4, and Audi e-tron. However, fitting a tracker or immobiliser to an EV requires different considerations than a petrol or diesel car – including 12V battery capacity, high-voltage safety, and warranty compatibility. That is why Car Trackers for Electric vehicles need to be chosen and fitted with EV experience in mind, not just treated as a petrol car with a different badge.

EV-specific tracker considerations

EVs have two electrical systems: a high-voltage traction battery (400V-800V) for driving, and a standard 12V auxiliary battery for electronics. Trackers and immobilisers connect only to the 12V system – never to high-voltage components. This is the single most important rule of fitting Car Trackers for Electric vehicles safely.

However, EV 12V batteries are typically smaller than those in ICE vehicles, so low-power devices and voltage monitoring are essential. LockCar systems draw minimal current (under 5mA in standby) and include programmable low-voltage cut-off to preserve 12V battery health. That means the tracker can run continuously without shortening the life of the auxiliary battery or affecting how the car starts.

Compatibility with EV makes

LockCar devices are compatible with all EV makes including: Tesla (Model 3, Y, S, X), Nissan Leaf, VW ID.3/ID.4/ID.5, BMW i3/i4/iX, Hyundai Ioniq 5/6, Kia EV6, Ford Mustang Mach-E, Mercedes EQ range, Audi e-tron, Polestar, and MG EV. Our installers understand EV-specific wiring and CAN bus protocols, ensuring seamless integration without affecting charging, range estimation, or driver assistance systems.

This matters because an EV is not just a different engine – it is a different electrical architecture. A tracker that would be perfectly safe on a diesel hatchback can behave differently on a high-voltage platform if it is not installed with the right knowledge. Our approved installers fit Car Trackers for Electric vehicles regularly, so the installation is treated as routine rather than experimental.

How it stops relay and key-cloning theft

Most modern EV theft does not involve breaking a window or hot-wiring anything. Thieves use relay equipment to capture the key fob signal from outside your home, or they clone the key by accessing the vehicle’s diagnostic systems. Both methods leave the car’s own security satisfied, because as far as the car is concerned, the correct key is present.

An immobiliser changes that. LockCar fits a physical break in the start or drive-authorisation circuit that stays open until you authorise it with a proximity tag, app, or PIN. Relay equipment cannot bridge that break, because it is not a radio signal – it is a physical interruption in the wiring. Even if thieves unlock your EV, it will not move. On the One Plus, you also get a live alert if the vehicle is disturbed, plus GPS tracking and remote immobilisation, so you know immediately and can act.

For owners who want the full picture on EV-specific threats, our guide to preventing modern electric car theft explains what is happening and how to respond.

The fitting process step by step

First, contact us by WhatsApp or phone with your EV make, model, year, and location. We confirm which device suits your car and agree a fitting time and place – usually your home or workplace. If you have questions about warranty or the 12V battery, ask them now and we will answer honestly.

On the day, an EV-experienced installer arrives with everything needed. The device is fitted to the 12V system, concealed within the vehicle, and wired so it does not interfere with charging, range estimation, or driver assistance. The system is tested with you present, the app or tag is paired, and you get a full walkthrough before the installer leaves. Most installations are completed in a single visit.
