How many locks should be on the front door?

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.

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.
