In terms of security, there have been significant developments in recent years. When buying a door, you should first pay attention to the so-called resistance class. Resistance class doors 1 offer the least, Resistance class doors 6 the highest security. Ideally, doors with glass inserts should also be secured by a grille in front of the pane or made of burglar-proof glass. The door should always be installed by a specialist, so that there are no unintentional security weaknesses. Incorrect installation of doors is also a reason for a household insurance to refuse claims settlement.
The lock area is the most important and at the same time the most complicated link in door construction. In addition to the well-known key systems, there are a number of other keys, which use a special mechanism to make a door even more secure. A so-called pass-through key forces the residents to lock their front door, in that it cannot be removed when the lock is open. Doors with multiple locks are even safer, which can only be opened when all the keys are in the individual locks. If you do need a key service, these locks can only be opened with special milling machines. These rather complicated locks are being replaced by electronic locks, where codes have to be entered. An extremely modern and expensive variant are locks that react to fingerprints. Finger profiles of the house residents are stored by a computer system. This means that only authorized persons can get inside the house. Opening such doors is only for experienced locksmiths, like the Hamburg locksmith, feasible with milling machines.
