Smart Electronic Lock LINKEY (Linky Plus)

  • Official site

A must-see for those who prioritize cost performance. The LINKEY series smart locks for businesses help reduce ongoing costs.

What is the LINKEY series? LINKEY is a smart lock that streamlines your business operations. Currently, we have LINKEY Plus, which is well-received and available for small to medium-sized businesses such as vacation rentals, and LINKEY Pro, a new product set to launch in February 2025, recommended for managing multiple keys. LINKEY Plus / Pro Pricing Plans LINKEY Plus: *Please refer to "Pricing Information" for details. This communication method connects one relay device for each LINKEY unit. It offers the advantage of being more cost-effective than LINKEY Pro when operating a small number of units (1 to 3). It is also recommended for those looking to implement it across multiple buildings! LINKEY Pro: *Please refer to "Pricing Information" for details. *One relay device is installed per floor. LINKEY Pro allows you to manage all LINKEY units on a single floor with one relay device. Therefore, for customers who want to manage many locks on one floor, LINKEY Pro is recommended! Customers considering four or more units on one floor can benefit from using "Pro" at a better price!
