Smart locks, the latest in security: how much does it cost to install them at home and forget about keys?

In a context where technology is moving toward automated homes , with thermostats and lights activated from a cell phone, smart locks are beginning to gain greater relevance. It's no longer just about replacing a traditional lock with a modern one, but rather incorporating a system that allows you to open a door with a fingerprint or magnetic card, eliminating the need for keys .

This type of product—which operates via Wi-Fi, Bluetooth, mobile apps, and multiple authentication methods—is becoming increasingly popular due to its practicality in a home, apartment, office, or temporary rental. It's also important for the security and autonomy it offers in the event of forgetfulness or unexpected events .

One of the most recent offerings in this segment is the NHS-D100 , from the manufacturer Nexxt Solutions Home, which arrived in Argentina with the aim of responding to a growing demand from households seeking hassle-free technological solutions, according to the company.

This model allows you to unlock a door using an Android or iPhone app, voice commands, a digital keypad, or a traditional physical key.

Its autonomous operation—powered by batteries—ensures up to 10 months of use without recharging and has a USB port for emergencies.

“Home and building security has evolved significantly in recent years, with smart locks and access systems playing a key role in this process,” explained Erika Merlo, Southern Cone Territory Manager for Nexxt Solutions Home.

He added: "These devices not only offer convenience, but also raise the bar on security , allowing for more personalized access control."

One of the notable advantages of the model is the ability to generate temporary or permanent access codes , which can be shared with family members, visitors, or occasional employees, without the need to hand over a physical key .

Additionally, from the Nexxt Home app, you can receive real-time alerts about who enters or leaves your home, and view a history of accesses with details on times and failed attempts.

Another strong point of this lock is its integration with other smart devices , as long as they're part of the Nexxt ecosystem. Through programmable "scenes," it's possible, for example, to automatically turn on lights or activate air conditioning systems when the door is unlocked.

Installation is simple, compatible with left- and right-hand opening doors, and the product comes with all the hardware included. Simply connect it to your home Wi-Fi network and configure it from your mobile phone.

For its part, Ezviz , a company specializing in smart home solutions, has the DL05 model , which combines a modern design with multiple security functions.

This lock allows access to your home via multiple methods: proximity card, numeric code, or mechanical key. It can also be controlled remotely from the EZVIZ app, either via Bluetooth or Wi-Fi.

However, one of the differentials of the DL05 model is its fingerprint sensor on the door handle , which allows store up to 50 biometric profiles locally and activates a security lock after five failed attempts within five minutes. It also provides automatic alerts in case of attempts to force the lock or if someone attempts to remove it.

Additionally, being integrated into the Ezviz ecosystem, it allows synchronization with the brand's security cameras, which are automatically activated upon detecting entry, adding a layer of real-time visual monitoring.

The IHUB F50 NP model, from the Panzer brand, represents another advanced option for safeguarding the security of homes and apartments.

Designed for doors between 35 and 65 millimeters thick, this lock can be controlled via Bluetooth and Wi-Fi through its mobile app, and offers various access options: fingerprint, RFID card , numeric code, touch keypad, or emergency mechanical key.

One of its strong points is its storage capacity: up to 200 fingerprints, 200 proximity cards and 150 keys, making it an ideal option not only for the home, but also for offices or spaces with high traffic .

Its design includes a card reader, fingerprints, and a "Do Not Disturb" mode , designed to block access or notifications during certain times.

In addition, it has protection against electric shocks , and an estimated autonomy of up to 12 months with average use of 10 accesses per day, powered by four AA batteries .

Another factor to consider is the alleged technical problems that this type of device can present compared to mechanical locks. "The advantages of this device far outweigh the problems that may arise," said Marcelo González, Commercial Director of Ezviz, in an interview with Clarín. The key, he explains, lies in proper installation.

Most problems arise when the product is not installed precisely: "It requires exact measurements. If the holes don't match up correctly, there could be a problem with the mechanism. For example, if the latch rubs against the wood, the handle becomes stiff, and this creates friction and wear that can affect the lock and the door structure," he acknowledges.

Furthermore, since these locks are often battery-powered, the mechanism's strength is limited: "It's not the same as what you can apply by hand. That's why everything has to fit perfectly, without having to use force to lock or unlock."

The same goes for the frame: the bolts must slide in smoothly, without friction. "Otherwise, it won't close or could stick, especially on wooden doors that swell with moisture or heat."

"The person installing it needs to have some knowledge, at least enough to use a drill, take measurements, and understand how the door works. If a hinge is loose or the door moves too much, that can also lead to failure over time," he added.

In apartments, these digital locks also offer an additional advantage: if a gust of wind closes the door without a key, the user isn't locked out, as is the case with ordinary doors. There's also no need to call a locksmith or pay a high fee for emergency opening.
