Car theft and parts theft in Germany: should you worry?
In Germany, a car is often an investment, a work tool, or the family’s daily transport. The overall crime level may feel “low”, but car theft and parts theft (wheels, headlights, catalytic converters) remain real risks — especially in large cities such as Berlin, Hamburg and Cologne.
Practical takeaway: car protection in Germany is not paranoia — it’s sensible risk management. Especially if your car is parked outside overnight, has Keyless entry, or has expensive components (lighting, rims, catalytic system).
⚠️ A) Should you install an aftermarket alarm system in Germany?
Is factory protection enough?
Modern cars typically have an immobiliser, central locking and basic factory sensors. The key issue in recent years is Keyless (vulnerability to relay attacks, where attackers relay your key signal). That’s why “factory” doesn’t always equal “secure”.
When an extra alarm system makes sense
- 📌 your car is parked outside or in a public parking area;
- 📌 your model is popular with thieves (premium brands, SUVs, high-demand VAG/BMW/Mercedes models);
- 📌 you have Keyless and often park in dense street-parking areas;
- 📌 you drive/park in Berlin or a major city and want phone notifications.
Common system types you see in Germany
| Option | What it does | Best for |
|---|---|---|
| Shock/tilt sensor | Detects forced entry or jacking up the car | City parking, wheel-theft risk |
| Engine immobilisation | Prevents start without authorisation | Keyless cars, premium segment |
| GSM alarm | Phone notifications + event logging | When the car is often out of sight |
| GPS/GSM combo | Notifications + tracking | If you want a “Plan B” after theft |
Pros and cons
| Pros | Cons |
|---|---|
| Raises the overall protection level and complicates “quick theft” | Cost is typically €500–€1,500 (equipment + installation) |
| May affect Kasko conditions (depends on insurer/policy) | Cheap/poor installs can cause false alarms |
| Increases attacker time → higher chance of being noticed | Requires professional installation (electrics, clean integration) |
⚠️ B) GPS tracker in a car: is it legal in Germany?
Can you install a GPS tracker in your own car?
In general: yes. Installing a GPS tracker in your own car in Germany is usually permissible. But once other people use the vehicle (spouse/relative/employee/renter), you enter the world of GDPR/DSGVO and German data-protection rules.
Legal nuances people often miss
| Scenario | What matters | Risk level |
|---|---|---|
| Only you drive the car | Minimal issues: you process data about your own movements | Low (with reasonable settings and secure access) |
| Other people drive the car | Transparency matters: the person should know tracking exists and why | Medium/high: hidden tracking can be problematic under Datenschutz |
| Company car / employer | Often requires written information, purpose limitation, data minimisation, proportionality | High: employment law + Datenschutz, sometimes a works council (Betriebsrat) |
When a GPS tracker is actually useful
- higher theft risk (premium brands, high-demand models, major city);
- long-term outside parking or public parking;
- international trips, long business travel;
- post-theft recovery strategy (as part of a package: alarm + mechanical protection).
Typical cost ranges you see on the market
| Item | Typical | Comment |
|---|---|---|
| Device | €50–€300 | Features vary: sensors, battery life, app quality |
| Installation | €100–€400 | Depends on power access and hidden wiring |
| SIM/subscription | €3–€10 / month | If you need online tracking and alerts |

⚠️ C) Wheel locks and mechanical protection
What are “wheel locks” (Radschrauben mit Diebstahlschutz) ❓
These are wheel bolts/nuts with a unique pattern that can’t be removed with standard tools. They’re especially relevant if you have expensive wheels/tyres (BMW, Mercedes AMG, Audi, etc.).
How effective are they?
- they are not a 100% guarantee (professionals can have special tools),
- but they significantly increase theft time and often deter opportunists,
- they work best as a package: wheel locks + good lighting + alarm/tilt sensor.
Other mechanical protection options
| Tool | Why | Comment |
|---|---|---|
| Steering wheel lock (Lenkradkralle) | Complicates quick theft | Simple, often effective psychologically |
| Gearbox lock | Physical barrier | Requires installation but increases attack time significantly |
| OBD port protection | Against key programming / CAN access attacks | Very relevant for many models (especially together with Keyless) |
⚠️ D) Practical tips for protecting your car in Germany
1) 👓 Keyless: cheap and effective basics
- Use an RFID-shielding pouch (Faraday bag) for the key.
- Don’t store the key near the front door/window (reduces relay-attack risk).
- If your model allows it, disable Keyless or switch to “button-only” access.
2) 👓 Don’t keep documents in the car
Ideally, keep Zulassungsbescheinigung Teil II separately. Documents in the cabin can make follow-up fraud and “parts selling” easier.
3) 👓 Parking strategy
- If possible: underground garage or a guarded/secured parking.
- If street parking: choose well-lit areas, cameras, high-traffic spots.
- Avoid always parking in the same hidden corner with low visibility.
4) A protection package beats a single device
A reasonable setup often looks like this: Keyless protection + OBD protection + a mechanical barrier + (if needed) GPS/GSM. This increases attack time, raises the chance of mistakes, and improves the chance someone notices.
Insurance and protection in Germany
Additional protection (alarm/immobiliser) can sometimes affect Kasko conditions, depending on your insurer and policy. In some cases, the insurer may ask for proof of installation (invoice/certificate from the workshop). If you invest into a serious setup, keep the paperwork — it also helps when you sell the car.
Protection starts before you buy the car
An underrated truth: protection depends on healthy electronics, correct module operation, and no shady wiring. A car after serious damage or poor repairs can have vulnerable points: locks, sensors, Keyless modules and CAN lines.
What does a pre-purchase inspection in Berlin/Germany give you? ❓
- 📜 Control unit scan: SRS/BCM/door modules, tampering signs, unusual events.
- 📜 Body check: paintwork, repair traces, lock/door zones condition.
- 📜 Keyless/electrics review: correct behaviour, suspicious symptoms, hidden issues.
- 📜 History logic: comparing seller claims with service records and data consistency.
Checklist: a practical car protection plan in Germany (no overkill)
| Step | What to do | Why |
|---|---|---|
| 1 | Keyless: Faraday pouch / disable Keyless if possible | Reduces relay-attack risk |
| 2 | OBD protection (lock / relocation / access limitation) | Makes CAN/key attacks harder |
| 3 | Wheel locks + tilt sensor (if needed) | Against wheel theft and “quick jack” attacks |
| 4 | GPS/GSM tracker (if high risk / street parking) | Post-theft plan + alerts |
| 5 | Parking: lighting / cameras / underground parking | Often stronger than any device |

In most cases — yes, if it’s your car. If other people drive it, transparency and GDPR/DSGVO principles matter.
Is an alarm system worth it in Germany?
Often yes — especially in Berlin and with Keyless and street parking. Quality equipment and proper installation are key.
Do wheel locks help against wheel theft?
Yes, as an extra barrier: they increase theft time and often deter “quick” attackers, especially together with good parking and a tilt sensor.
