Expert advice for more security in your own four walls
There’s a burglary in Germany every three minutes—a shocking statistic that demonstrates how important effective burglary protection has become. As an experienced Schlüsseldienst Karlsruhe, who also works for the police and government agencies, we know the weak points of apartments and houses inside out. This guide will teach you which proven measures you can use to effectively protect your home.
The reality: Burglary statistics for Karlsruhe and Baden-Württemberg
In Baden-Württemberg, over 8,500 residential burglaries were recorded in 2024. Karlsruhe, a city with over 300,000 residents, was particularly affected. The good news: 43% of all burglary attempts fail due to good security measures.
Typical burglary times:
- Monday to Friday: 10:00 a.m. to 6:00 p.m. (when most people are working)
- Weekends: Evenings between 6:00 p.m. and 11:00 p.m.
- Dark season: October to February particularly affected
Popular entry routes:
- 80% through ground floor windows and balcony doors
- 15% through the front door
- 5% through the basement or attic
1. Mechanical door security: The basis of any burglary protection
High-quality door locks are indispensable
A standard lock only stops experienced burglars for a few seconds. Invest in certified security technology:
Minimum standard for front doors:
- Security class SK2 according to DIN 18252 (resistance 3 minutes)
- Locking cylinder with security card to prevent duplicate keys
- Emergency and hazard function for escape routes
Additional security measures:
- Multi-point locking with at least 3 locking points
- Reinforced deadbolt as a cross-lock
- Security fittings with cylinder cover
- Door gap lock to prevent prying
Professional tip from the locksmith
Never leave the key in the lock from the inside – this prevents escape in an emergency and makes it easier for burglars to drill out the cylinder.
2. Window security: The underestimated weak point
Why windows are so vulnerable
Standard windows can be opened in 10-20 seconds with a simple screwdriver. Modern window locks significantly increase resistance:
Effective window security:
- Mushroom-headed pin fittings (RC2 standard minimum)
- Screw-on window latches for older windows
- Lockable window handles for basic security
- Window grilles for particularly vulnerable areas
- Security film to prevent glass breakage
Balcony doors and patio doors:
- Crossbar lock for additional stability
- Hinge side security against prying
- Roller shutters with reinforced guide rails
3. Lighting as a natural deterrent
Light Deters Burglars
Burglars avoid bright, easily visible areas. Strategic lighting is one of the most cost-effective security measures:
Optimally plan outdoor lighting:
- Motion detectors at all entrances
- Continuous LED lighting for the house entrance and garden
- Timer simulates presence when you’re away
- Smart home lighting with app control while you’re away
Interior lighting when away:
- Light different rooms at different times
- Use a TV simulator to simulate presence
- Don’t leave blinds closed permanently
4. Alarm systems: Modern security technology for every budget
Wireless alarm systems for beginners
Modern alarm systems have become more affordable and can often be installed by yourself:
Basic wireless alarm system features:
- Control panel with GSM module for notifications
- Door and window contacts for all access points
- Indoor motion detectors
- Outdoor siren with flashing light for deterrence
Smart home integration:
- App control for arming/disarming
- Video surveillance with recording
- Smoke detector integration for fire protection
- Smartphone notification in case of alarm
Professional monitoring
For maximum security, we recommend connecting to an emergency call and service control center:
- 24/7 monitoring by a security service
- Automatic notification of the police and fire department
- Regular system maintenance and updates
5. Video surveillance: deterrence and securing evidence
Observe legal principles
Video surveillance has a strong deterrent effect, but must be GDPR-compliant:
Video surveillance is a strong deterrent, but must be GDPR-compliant:
Permitted surveillance areas:
- Your own property (excluding neighboring properties)
- House entrance and direct access routes
- Garage and carport
Not permitted:
- Monitoring public paths
- Recording of neighboring properties
- Hidden cameras without signage
Modern camera features:
- 4K resolution for sharp images
- Night vision with infrared LEDs
- Motion detection with push notifications
- Cloud storage as backup
6. Presence simulation: Simple and effective
Creating the impression of being at home
Presence simulation is one of the most effective and inexpensive protective measures:
Technical tools:
- Timers for lights and radio
- Smart plugs with irregular switching times
- TV simulator with changing color patterns
- Blind control with daylight-dependent automatic operation
Analog tricks:
- Park your car in a visible location in front of your house
- Ask neighbors to empty your mailbox
- Arrange for garden maintenance by friends
- Avoid using social media while on vacation
7. Neighborhood Help: The Social Safety Net
Attentive Neighbors Are the Best Alarm System
A vigilant neighborhood is often more effective than any technology:
Build a neighborhood network:
- WhatsApp group for quick communication
- Exchange emergency contacts
- Arrange vacation care for each other
- Report suspicious activity immediately
What neighbors should be aware of:
- Strangers “scouting” houses
- Vehicles repeatedly driving slowly down the street
- People ringing doorbells and inspecting the property
- Unusual activity at unusual times
