Before you start
If you believe someone is tracking you on purpose, don't search somewhere isolated or near that person. Have a friend with you or go to a public car park. You'll need a torch and, ideally, a small mirror.
Where to look
- Inside the cabin: under and between the seats, seat-back pockets, door pockets, glove box, centre console, and behind the sun visors.
- Boot: the spare-wheel well, side compartments and under the boot floor.
- Under the car: inside the wheel arches, on top of the tyres' inner liners, behind the bumpers and along the underside. Magnetic cases are common.
- The diagnostic (OBD) port under the dashboard. Some trackers plug straight in. If you don't recognise something plugged in there, photograph it and get advice.
Scan while you drive
- Open TrackerGuard on a phone in the car and press Scan. Allow Bluetooth and Location.
- Drive or walk between a few different places for about 30 minutes. Park away from other cars if you can, so that nearby tags don't confuse the result.
- Check the dashboard. A device marked Following you has stayed with you across several places.
- If something flags, search the car again, using the phone's signal strength as a hint: it grows stronger as you get closer.
What a Bluetooth scan cannot find
A tracker with its own SIM card and GPS does not behave like an AirTag, and a Bluetooth scanner will not see it. If you have a real reason to worry and find nothing, a mechanic or a security specialist can sweep the car, including wiring.
If you find one
Photograph it where it sits, then follow what to do when you find an AirTag. Don't remove it before you have evidence if you intend to report it.
In testing. Use TrackerGuard as one signal, not a guarantee.
