Summer is the time when visitors come and go at home, kids spend their holidays with grandparents, and many of us leave for vacations, leaving the apartment or house unattended. This is exactly when swapping a traditional lock for an intelligent one makes a lot of sense. WELOCK has just launched its summer sale on smart locks that replace classic keys with more convenient access via a fingerprint, PIN code, RFID card, or a mobile app.
Great prices on WELOCK smart locks during the sale
You can find WELOCK smart locks in the brand’s official store. They’re stocked directly in the European and UK warehouses, meaning fast delivery with no extra fees! Don’t forget to use the coupons from the price boxes as well.
WELOCK is a global pioneer in smart locks and biometric security systems, known as the first innovator to integrate advanced fingerprint recognition directly into cylindrical lock inserts. In practice, that means it’s not just a “door gadget”, but a solution designed to simplify everyday home, office, or rental property access.
Before we look at the individual products in this sale, it’s important to mention why it’s worth handling your purchase through the official website. WELOCK has built a reputation not only for quality hardware, but also for services you’ll appreciate when buying from Slovakia or the Czech Republic:
- Free delivery from EU and UK warehouses: No customs clearance, no additional top-ups, and most importantly—fast courier delivery right to your door.
- 30-day money-back guarantee: If the lock doesn’t suit you for any reason, you have a month to return it.
- 2-year worry-free warranty: Full support and a two-year service guarantee is a given.
- Lifetime customer support: Whenever you need help setting up the lock or using the app, support is available to you.
WELOCK U81: An advanced model for demanding users
WELOCK U81 is one of the main stars of the current summer sale. It offers 6 unlocking methods including a fingerprint, PIN code, RFID, an app, and other options—making it ideal for households where more than one person uses the lock.
When using the WIFIBOX3 gateway, it also supports remote access, Alexa, and Home Assistant — so you can unlock the door even for a distant family member who’s feeding your cat while you’re on the other side of Europe. The advantage is easy installation without drilling, compatibility with euro cylinder inserts, and a battery life of about 12 months, along with a low-battery warning.

WELOCK SECBN51: A practical smart lock for family houses
WELOCK SECBN51 is mainly focused on keyless access via a fingerprint, and when used with WIFIBOX3 it can also offer remote control via a mobile app, plus support for Alexa and Home Assistant.
This makes a big difference especially for family houses, where household members often swap during the summer, kids arriving from camp, or grandparents. The manufacturer states that the lock replaces the existing cylindrical insert without drilling or wiring, so it isn’t a complicated modification of your door. Simplicity of installation is a major advantage with these products.

WELOCK ToucA51: The best value for money and features
If we had to pick the model that makes the most sense for most typical households, it would be WELOCK ToucA51. It offers 6 unlocking methods, easy installation, and the ability to add up to 10 administrators.
This model is suitable for households, summer Airbnb rentals, and offices. It supports the euro door standard with a thickness of 30 to 95 mm, and its biggest advantage is the combination of a fingerprint and a keypad. If you’re coming back from the pool with wet fingers, you can simply use the PIN code or another available unlocking method.

WELOCK Smart Keybox: The ideal companion for vacation rentals
The current summer sale also includes the WELOCK Smart Keybox — a secure smart key storage box that makes the most sense for Airbnb, short-term summer rentals, service access, or situations where you don’t want to leave keys with neighbors or under the doormat.
During the summer season, when several groups of guests rotate through a rented cottage or apartment, you’ll especially appreciate that you can change the box code remotely at any time and completely avoid handing over the keys in person.

The last product in this sale is the WELOCK WIFIBOX3 — a gateway that adds remote control, app-based management, and smart home integration including Alexa and Home Assistant to selected WELOCK smart locks. If you want to manage home access even when you’re on vacation, the WIFIBOX3 is an add-on worth considering.

Where does WELOCK make the most sense in summer?
For short-term summer rentals like Airbnb, a smart lock can greatly simplify guest management. Time-limited codes allow self check-in without handing over keys in person, which is especially useful for hosts handling multiple arrivals during the peak season or who don’t want to be physically present for every stay.
In family households, the main advantage is convenience during the holiday months. Kids, grandparents, or neighbors who come over to water the flowers can use their own way of unlocking, and you don’t have to deal with lost or unreturned keys. When you leave for vacation, it also makes sense to be able to remotely check at any time whether the door is locked, or temporarily add access for a neighbor who comes to check on your apartment.
Real-world experience: What do users say after years?
Our readers have been writing for years that WELOCK is the kind of gadget that becomes part of your routine after just a few days. Once you get used to the convenience of unlocking with a fingerprint or code, it quickly feels like second nature. Our long-time reader Ladislav has been using these locks since 2017, and his nearly ten years of experience confirm their reliability:
Ladislav: “The locks are very accurate, fast, and reliable, and they handle everyday household use without you having to constantly “tune” them. At the same time, it’s fair to say what happens with biometrics almost always, regardless of the brand — fingerprints aren’t always perfectly readable when your fingers are wet or when a child’s fingerprint is still developing.”
That’s exactly why having an alternative makes a lot of sense in 2026. Whether it’s an RFID card, an app, or, on the ToucA51 model, a built-in PIN keypad. Ladislav puts it simply: most of the time he unlocks with his finger and is happy, but when his fingers are “unusable” (for example after swimming or gardening), he reaches for the card or his phone and keeps going without any stress.
