Anti-bump lock cylinders: "the lock is only a deterrent"

Anti-bump cylinders: paying more won't stop a hole in the wall

A neighbourhood shaken by a wave of break-ins. That is the scenario that triggers the panic buying of high-security cylinders: KABA Expert, TESA TK100, Winkhaus blueChip, Mottura Champions. The premise running through the whole conversation is an uncomfortable one: the lock is only a deterrent. If they want to get in, they get in. And when they do, a hole knocked through the neighbour's wall or a hydraulic jack against the window grille leave the best cylinder on the market looking the other way.

Which anti-bump cylinder to buy, and why price isn't everything

The range of options on the table is wide. The KABA Expert 007 comes with 22 pairs of high-precision pin stacks and a three-minute installation with a screwdriver. The TESA TK100 adds an uncopyable patented system, an orbital combination and a shield built into the rotor. The Winkhaus blueChip is electronic, self-powered and has just peine an online store for private customers. Also mentioned are the Mottura Champions, the Ezcurra and the KESO.

The price range is broad. Some point out that a TESA TX80 costs around 60 euros and that its keys can only be copied at the factory. The electronic blueChip sits well above that. The question hanging in the air is whether that difference buys anything more than peace of mind.

Burglary insurance and the fine print almost nobody reads

This is where the most repeated and least segarro argument appears: the only thing that matters is having burglary insurance. And one condition that gets overlooked: if the thief doesn't force the lock, the insurer may not cover anything. Hence the real value of an anti-bump, anti-picking cylinder: not preventing entry, but ensuring the door shows damage and the claim is payable.

Some go further and claim that theft insurance, in certain policies, is a robbery in itself. The nuance matters: the policy covers the contents, not your peace of mind.

Uniform security: the hole in the wall, the glass panel and the switched-off camera

The strongest consensus is that security must be uniform. There is no point fortifying your door if next door there's a glass wall with ordinary glass. Or if your neighbour has a worse lock. Or if the security camera records in the dark because someone decided to switch off the light to save money. These are real cases that come up in the discussion, and they explain why the cylinder, on its own, is just a patch.

Keeping a low profile, a DIY alarm and the unsettling fact

The most pragmatic camp recommends looking poorer than you are. An old car, a shabby door, rumours of debts with the local baker. The theory is that an upmarket door acts as a magnet for upmarket thieves. Against that, some build homemade Arduino alarms that call your mobile, IP cameras and an unpretentious TESA TK100 lock.

The unsettling fact comes from an industry professional: there is a type of incivil for whom a security door poses no problem whatsoever. With that on the table, the question is no longer which cylinder to buy, but how much of that purchase is security and how much is ritual.
