The burglary resistance of entrance doors depends, first of all, on the quality of the locks. And secondly — from their number.
It is best not to save on locks for the front door, because. the losses from breaking will in any case be much greater than the costs incurred for the purchase and installation of locks. And, yes, of course, use only multi-bolt locks with a complex mechanism for entrance doors.
Time is everything
The main thing in property protection is to gain time. Remember, any lock installed on your door will be opened sooner or later anyway. Therefore, you should make sure that uninvited guests tinker with opening the lock for as long as possible.
It is unlikely that someone bad will spend the whole day digging at your doors — this is not safe for him. If your lock is able to detain a burglar for an hour or more, consider yourself well protected, you still won’t do more with the help of a lock.
The burglary resistance of entrance doors depends, first of all, on the quality of the locks.
You don’t have to believe beautiful advertising that there are absolutely burglary-resistant locks, if even heaped safes are opened, then the lock from the front door is even more so. But if your lock is reliable, well installed, then the risks of penetration into your home will be almost zero.
It’s just that the robber will have to incur such costs to penetrate your home that it will be unprofitable for him, it’s easier to find another option.
How many castles will be just right
But even one very good lock is not an option for reliable protection of the house. It is optimal if there are 2–3 locks on the front door. More is too much. This is inconvenient — just imagine what a bunch of keys every household will have to carry every day! And most importantly — a lot of locks, paradoxically, reduces your security.
The explanation here is this — the more keys, the easier it is to lose them. And the loss of a key means that the lock needs to be replaced. What “does not like” no door.
It is better to put two locks on the front door: a cylinder lock for convenience, and a main lever type for protection.
A door locked with two locks is very difficult to break open. The lever lock performs a power function, and such a lock cannot be knocked out. A cylinder — does not lend itself to master keys. Locks with different types of locking are installed at a distance of 30 cm from each other.
Some owners are insured and install 3 locks at the entrance. It’s more expensive, less convenient (you’ll have to spend more time opening every day), and a little more secure. Do you need it? Decide for yourself.
