Introduction of Keylex Adoption Cases - Public Transportation

The convenience and security of button-type locks.

There are many instances where our Keylex has been adopted in various public transportation facilities and pathways, such as railways and airports. Since entry and exit are done by pressing a button to enter a PIN code, there is no need to carry keys, and it is possible to lock and unlock without using power or batteries, making it a highly convenient product. Additionally, it can restrict or prohibit access from individuals not associated with the facility, thereby enhancing security. Changing the code is also easy, which helps reduce the hassle and cost of cylinder replacement, making it very economical. The Keylex, with its rich track record of adoption, is also utilized in situations beyond public transportation. 【Features】 ■ It allows for restricted access for a specific number of individuals. ■ With the automatic locking type, it prevents forgetting to lock, ensuring it is always in a locked state. ■ Being button-operated, there is no need to carry keys. ■ It has a mechanical mechanism that does not require electrical work. ■ Code changes can be made easily, allowing for low-cost maintenance of security.

Keylex is also adopted in collective housing such as condominiums and apartments, as well as garbage collection areas. There is no need to carry keys, and since it is a keypad type, it visually promotes security. In rental housing, it is necessary to change the keys when tenants change, but with Keylex, you can easily change to a new PIN code, eliminating unnecessary costs and hassle! Not only for housing, but Keylex effectively resolves concerns such as, "There are many illegal dumps in the garbage collection area, and I want to restrict use by non-residents. However, giving keys to all residents is also..." With its keypad system, it keeps outsiders away, eliminating worries about theft of aluminum cans or arson. There may be cases where the collection area does not have a roof or awning. Keylex is a mechanical type that does not use electricity or batteries, so it is not affected by outdoor environments such as being exposed to rain! 【Features】 ■ It allows for restricted access for a specific number of people. ■ With the automatic locking type, you can prevent forgetting to lock the door and maintain a locked state at all times. ■ Since it is button-operated, there is no need to carry keys. ■ It has a mechanical mechanism that does not require electrical work. ■ You can easily change the code, allowing for low-cost maintenance of security.

Keylex Case Study Introduction - Store (2)

Free yourself from key management! Enjoy a stress-free environment with keyless access!

This is the second installment of the "Keylex Case Studies Introduction: Store Edition." Keylex is being adopted and implemented in stores and commercial facilities. I believe that restaurants and similar establishments that employ many part-time or temporary workers often struggle with key management. With Keylex, doors can be opened with a button press, eliminating the need to prepare keys for each employee and preventing issues related to lost keys or retrieving keys from departing employees! With the automatic locking type, the door locks automatically when closed, preventing any forgetfulness in locking up after closing. If the store is not open 24 hours, it is also possible to restrict access at night to prevent unauthorized entry by those who know the passcode. The deadlock feature that disables button operation is available in the 1100, 2100, and 4000 series! It has a reliable mechanical structure that can be installed outdoors! 【Keylex Features】 - Allows for restricted access for a specific number of individuals. - The automatic locking type prevents forgetfulness in locking and ensures the door is always secured. - No need to carry keys as it operates with buttons. - It has a mechanical mechanism that does not require electrical work. - Easy to change the code, allowing for low-cost maintenance of security.

Keylex Case Study Introduction - Educational Institutions (2)

A button lock that is advantageous not only in terms of security but also in cost!

This is the second installment of the "Keylex Case Studies Introduction for Educational Institutions." Keylex has been implemented in a wide range of school facilities, including kindergartens, nursery schools, elementary schools, junior high schools, high schools, universities, and student dormitories. Since it is button-operated, there is no need to carry keys, and it can be used even in outdoor areas without a roof! You can set the passcode to any number you like, so even if the users, such as staff and students, change with the new school year, it can be easily updated to a new number without needing to replace the actual lock. Additionally, Keylex operates purely mechanically, so it does not require a power source. Unlike electric locks or battery-operated locks, it eliminates the costs associated with wiring work and maintenance due to battery depletion, making it cost-effective. We often see news reports about illegal intrusions and incidents on school grounds, but Keylex blocks unauthorized access by individuals other than those involved! **Keylex Features:** - Allows for restricted access for a specific number of entries and exits. - An automatic locking type prevents forgetting to lock, ensuring it is always secured. - Being button-operated means there is no need to carry keys. - It is a mechanical mechanism that does not require electrical work. - Allows for easy code changes, enabling low-cost security maintenance.

Keylex Case Study Introduction - Public Transportation (Railway Edition)

Can be installed in various locations! No electricity or batteries needed, so costs are reduced♪

Previously, we introduced examples of Keyless adoption in public transportation such as railways and airports, but this time we present a "Railway Edition" focusing on railway-related applications! The installation locations are diverse, including station master's offices, crew entrances, platform doors, kiosks and restaurants on the platform, restroom supply rooms, and crew accommodations, among others. The reason for its adoption in so many locations is the convenience of the button-type keyless entry. You can enter and exit by pressing the set passcode button, so there is no need to carry a key! This also eliminates the risk of losing keys. Another advantage of Keyless is that it does not require a power source or batteries. It is more affordable compared to electronic locks and has a completely mechanical mechanism, making it suitable for both indoor and outdoor use! We encourage you to consider the reliable Keyless, which has numerous successful applications!! 【Features】 ■ It allows for restricted access for a specific number of entries and exits. ■ With the automatic locking type, you can prevent forgetting to lock, ensuring it is always secured. ■ Since it is button-operated, there is no need to carry a key. ■ It has a mechanical mechanism that does not require electrical work. ■ You can easily change the code, allowing for low-cost security maintenance.
