Best tracker and immobiliser for a Toyota Prius
For a Prius, guard the catalytic converter as well as the car: fit a catalytic converter lock or marking, a CAN-bus immobiliser and a tracker with a movement alert. The DVLA recorded 644 Toyota Prius thefts in 2025, number 20 on the UK list.
Our pick for the Toyota Prius
For the Toyota Prius we recommend S7 tracker + immobiliser, as dual layer protection.
Layer one: stop it leaving
A CAN-bus immobiliser to stop the Prius being driven, plus a catalytic converter lock or cage.
Layer two: get it back
A Thatcham S7 tracker with movement alerts.
Worth adding
Mark the converter with your registration, and park so the underside is hard to reach.
Which setup suits your Toyota Prius
| Your car | Setup | Why |
|---|---|---|
| 2009 to 2015 (third generation) | Catalytic converter lock, immobiliser and S7 tracker | Converters from these cars are prized for their precious metals. |
| 2016 onwards (fourth and fifth generation) | Catalytic converter lock, CAN-bus immobiliser and S7 tracker | CAN injection and relay are risks on newer cars. |
Options compared for the Toyota Prius
| Option | Verdict | For this car |
|---|---|---|
| Tracker on its own | Not enough | A tracker does little to stop a converter being cut off in minutes. |
| Immobiliser on its own | Partial | Stops the drive-away, but not the converter theft. |
| S7 tracker + immobiliser | Our pick | Combine with a converter lock for full dual layer protection. |
| S5 tracker + immobiliser | Optional | Only where your insurer asks for driver recognition. |
Do insurers want a tracker on a Toyota Prius?
Insurers may pay out for converter theft, but excesses and waiting times can be long. Ask your insurer how converter theft is handled.
