Best tracker and immobiliser for a Ford Focus
A Focus is best protected by a CAN-bus immobiliser and a monitored S7 tracker. On a Focus ST or RS, choose an S5 tracker with driver recognition, because those cars are stolen to order. The DVLA recorded 1,474 Ford Focus thefts in 2025, number 3 on the UK list.
Our pick for the Ford Focus
For the Ford Focus we recommend S7 tracker + immobiliser, as dual layer protection.
Layer one: stop it leaving
A CAN-bus immobiliser so neither a relayed fob nor a stolen key can drive the car away.
Layer two: get it back
A Thatcham S7 tracker for family Focus models; an S5 tracker for the ST and RS.
Worth adding
Keys kept well away from the front door, as Focus thefts after house break-ins are common.
Which setup suits your Ford Focus
| Your car | Setup | Why |
|---|---|---|
| 2011 to 2018 (Mk3) | Immobiliser and S7 tracker | Key programming and stolen keys are the usual way in. |
| 2018 onwards (Mk4) with keyless entry | CAN-bus immobiliser, S7 tracker, fob pouch | Keyless trims are exposed to relay theft from the driveway. |
| Focus ST and RS | CAN-bus immobiliser and S5 tracker | Fast Fords are desirable whole and in parts, so recovery speed matters. |
Options compared for the Ford Focus
| Option | Verdict | For this car |
|---|---|---|
| Tracker on its own | Partial | Tells you where the Focus went, but a stolen or relayed key still starts it. |
| Immobiliser on its own | Good start | Removes the quick getaway after a key burglary, though a towed Focus would be lost without a tracker. |
| S7 tracker + immobiliser | Our pick | Right for the hatchback and estate most families run: it stops the start and traces the car. |
| S5 tracker + immobiliser | ST and RS | A driver tag on a fast Focus means a stolen key alone triggers an alert as soon as it moves. |
Do insurers want a tracker on a Ford Focus?
Insurers often ask detailed security questions on the Focus ST and RS, and some require a Thatcham tracker. For a standard Focus it is usually optional, but worth declaring.
Ford Focus tracker choices use the S5 and S7 Thatcham categories; S5 vs S7 explained; what insurers mean by approved.
Questions to ask your fitter
- If my keys are taken in a break-in, can the thief still drive the Focus with the immobiliser fitted?
- Will the tracker alert me if the battery is disconnected?
Ford Focus tracker and immobiliser questions
What is the best tracker for a Ford Focus?
A Thatcham S7 monitored tracker suits most Focus models, alongside a CAN-bus immobiliser. A Focus ST or RS is better served by an S5 tracker with a driver tag.
Are Ford Focus cars stolen with the real keys?
Key burglary is a common route. An immobiliser that needs a separate code or sequence means the keys on their own are not enough.
Is a tracker worth it on an older Focus?
If you rely on the car daily, yes. A monitored tracker gives police a live location, and the immobiliser stops most attempts before they start.
