After changing 3 sets of locks, I discovered that smart locks must adhere to the \”5 don\’t buy\” policy! It’s not a lie, it’s a lesson

Smart locks can be said to have become a must-have lock in home decoration.

Many friends want to replace the original mechanical locks with smart locks when they are renovating.

Smart locks are indeed better than mechanical locks in some aspects. But you have to learn to choose. If you choose incorrectly, it will become more difficult to use.

So, in this article, Home Furnishing Forum summarizes the 5 things you should not buy about smart locks. This is what I The lessons learned from replacing three sets of smart locks are by no means deceptive.

(1)——Don’t buy cheap smart locks

We are buying smart locks When purchasing, the first thing to note is never to buy a particularly cheap smart lock.

Everyone should also know that smart locks are smart locks. Prices vary greatly, ranging from a few hundred yuan to several thousand yuan.

However, you get what you pay for, which makes sense. So when we choose smart locks, we must also adhere to this principle.

Because cheap smart locks generally have the following problems:

①. The material precision of the lock cylinder of cheap smart locks is relatively poor.The failure rate may be relatively high, the service life is short, and it is very difficult to use.

②. Most of the cheap smart locks adopt a semi-automatic design. This kind of semi-automatic designed smart lock has no drive system inside, so the degree of automation is relatively low, and its safety protection measures are Relatively few

③. The protection level of cheap entry-level smart locks is not particularly high.And it is difficult to trigger the alarm, so the anti-theft performance is not high.

Purchasing Guide:

①. The first is the choice of smart lock price. My personal opinion is to try not to buy smart locks below 1,500 yuan. If you can buy it, try to buy a smart lock worth more than 1,500 yuan.

②. Brand selection. The second point we need to pay attention to is to try not to buy those off-brand or even unbranded smart locks. And try to buy some smart locks with better reputation and higher visibility.

③. When purchasing a smart lock, be sure to ask after-sales service specific situation. If there is no after-sales service, it is recommended to give up. It is only recommended that you buy smart locks that are safe and have good after-sales service.

(2) – Do not buy products with insufficient security level

The second thing to pay attention to when purchasing a smart lock is the security level

The so-called security level here basically refers to the anti-theft level of the lock cylinder.

The lock cylinder is a very important core in the door lock. The current lock cylinder is divided into three levels, namely A, B, and C. The highest safety factor is the C-level lock cylinder. .

Although the C-level lock cylinder is not completely anti-theft, it is higher than the anti-theft level of A and B levels.

The security level of the lock is not enough, generally There are the following problems:

①. Not anti-theft. Like our lock cylinder, if it is not grade C. Anti-theft lock, you will find that its production accuracy is very poor, which will greatly reduce the security.

②. The key workmanship is also very poor. Like a C-level lock One very notable thing about the core is that the key generally has double-layer holes and more than two kinds of tooth patterns, so its level of accuracy and protection is higher.

Purchasing Guide:

①. When buying smart lock keys, we only buy lock cylinders with C-level anti-theft level. For A and B levels, we do not recommend you to buy them. Because the anti-theft level of C-level lock cylinder is the highest.

②. Look at the workmanship. As for workmanship, generally we can only see the workmanship of the key. The more refined the workmanship of the key, the better. For example, there are double-layer holes and more than two kinds of tooth patterns. For simpler keys, don\’t buy it.

③. For the lock cylinder, try to choose stainless steel. The blade structure adopts a staggered design. The key step change is about 0.8mm, and the blade key error is 0.07mm. The lock groove blade gap is 0.05mm, you can check it when buying.

(3) – Do not buy one without lock core protection device

When buying a smart lock, do not buy a smart lock without a lock cylinder protection device.

Whether it is a traditional mechanical lock or the more common electronic lock, There is an emergency unlocking method.

The most common emergency unlocking method is basically to use a key to unlock. But there is one requirement here, that is, the lock cylinder should not be exposed.

So, for mechanical lock cylinders, there should be a protective cover. And there should be a device to prevent the lock from being unlocked.

Because without protection, the following problems will occur:

①, if The mechanical lock cylinder does not have a protective cover, so the lock cylinder is easily pried open, so it loses the meaning of safety protection.

②, if If the lock core does not have built-in anti-drilling bolts, anti-drilling discs, and other measures to prevent professional unlocking, our locks will also be unsafe.

Purchasing Guide:

①. When purchasing a smart lock, everyone should Check the specific workmanship of the smart lock. See whether there are removable bolts, screws, etc.

②, personal It is recommended that you try to choose one with a stainless steel shell to protect the internal structure. Because the internal structure can effectively prevent corrosion and theft.

③. Try to choose a hidden emergency unlocking device. In other words, our lock cylinder should be hidden inside as much as possible. We usually use electronic unlocking, and it can be removed in an emergency to reveal the lock inside. Core.

(4)-Don’t buy plastic casing

When purchasing smart locks for home use, it is not recommended that you buy smart locks with plastic shells.

The shell of the smart lock is divided into plastic material and metal material according to different materials.

Everyone should also know that a metal smart lock casing is definitely better than a plastic casing.

Because metal materials are better than plastics in terms of hardness and other aspects.

Moreover, plastic smart locks are generally The following problems exist:

①, Easy to break. Smart locks made of plastic will appear to be damaged after being bumped. If they are damaged, the components inside will be exposed. In fact, the smart lock will be ineffective at this time.

②. Poor anti-theft ability. Smart locks made of plastic are easily broken. After it is smashed, the components inside can be removed, and the smart lock will eventually become ineffective.

③. Not durable. We open the door every day. If the casing is not strong, the plastic casing will be worn, faded, or even cracked. Then the smart lock is basically broken and needs to be replaced.

Purchasing Guide:

①. When purchasing a smart lock, you must look at the material outside. In fact, you can touch and weigh it with your hands. The heavier the feel and the stronger the metal texture, the better the smart lock.

②. As for the material of the smart lock, it is recommended that you choose precision cast aluminum or alloy. The shell material of the metal smart lock has good texture and is wear-resistant and corrosion-resistant.

③. Among smart locks, there is a smart lock with an all-metal panel formed in one piece. This kind of smart lock is more beautiful, and its corrosion resistance and oxidation resistance are very good. Moreover, it will not be eroded by years of sweat and change.

(五)——Don’t buy one with low battery

When purchasing a smart lock, one thing you must not ignore is the battery power of the smart lock.

Because current smart locks basically rely on electricity to work, if there is no electricity, you will find that the smart lock will fail.

With intelligence The improvement of lock intelligence has also led to an increase in power consumption in many aspects.

If the battery of the smart lock is low, That is to say, the battery life is low, and generally there will be the following problems:

①. Frequent charging is required. Some smart locks need to be recharged every few weeks, and there is no spare battery. The battery needs to be removed when charging, which is very troublesome.

②. Smart locks require frequent battery replacement. This type of smart lock generally uses dry batteries, but its power consumption is relatively large, and the power of the dry batteries is relatively low, which results in the need to replace the batteries frequently.

Purchasing Guide:

①, select When purchasing a smart lock, it is recommended that you choose a smart lock with dual batteries. In this way, one battery has no power, while the other battery can continue to work.

②. When purchasing a smart lock, you can also look at another one, which is Dual batteries are independently powered. For example, two sets of batteries are used to power the lock cylinder and the cat eye camera, so even if the cat eye is out of power, it will not affect the opening and closing of the door.

③ When purchasing a smart lock, you should also pay attention to the battery life. In fact, what many smart locks reflect is the number of times the door is opened and closed. Of course, try to choose one with a higher number of openings or closings. Yes, there is a backup battery.
