Even in Berlin – from Mitte and Pankow to Spandau – no one can afford to ignore security. Yet many households make small mistakes that make things easier for burglars. In this article from Olex Schlüsseldienst Berlin, we show you the top 5 security mistakes that occur frequently – and how you can protect your home effectively.
Common Security Mistakes – and How to Avoid Them
Mistake 1 – Weak or Outdated Door and Window Locks
Many Berlin residents rely on standard lock cylinders without any special burglary protection. Simple locks can be overcome by picking, drilling or inexpensive tools.
Solution: Invest in burglar-resistant cylinders (e.g. with VdS certification, security fittings, pull and drill protection). Combined with sturdy and high-quality fittings, this significantly increases protection.
Mistake 2 – Leaving Windows or Doors Open, Even for a Short Time
Many people believe burglars strike only at night or that an open window during the day is harmless. Experience shows, however, that offenders also adapt to the time of day. An unlocked window is an invitation, even if you are away only briefly.
Solution: Always close and lock windows, balcony doors and patio doors, even when you are away for only a short time — and use additional security measures such as window bars, lockable window handles or sensors.
Mistake 3 – Relying Solely on Smart Home or Digital Security Technology
Many homeowners rely exclusively on smart solutions (alarm systems, video surveillance, app control). But such systems can be hacked, manipulated or disabled during a power outage. Planning and installation are also often carried out by non-professionals, which can create security gaps.
Solution: Use hybrid security concepts – mechanical security + tested, professionally installed digital systems. Also pay attention to IT security, secure passwords, updates and access protection.
Mistake 4 – Poor Lighting and No Visibility of the Building Entrance
Dark building entrances or poorly lit paths provide ideal conditions for burglars. Where there is little or no light, offenders feel more secure.
Solution: Install motion-activated or dusk-to-dawn lighting at entrances, in the garden, hallway and access areas. Additional outdoor cameras or video intercoms can also significantly reduce opportunities to hide.
Mistake 5 – No Attention to the Neighborhood and Lack of Neighborhood Awareness
Anyone who lives in isolation and does not know the surrounding area may miss important warning signs. Suspicious visitors or unusual noises can then easily go unnoticed.
Solution: Get to know your neighbors or people in your building. Arrange neighborhood watch activities or active communication (e.g. via apps, groups or notices). Many burglary attempts already fail when witnesses are present or someone regularly keeps an eye on things.
