CLIQ®: locking solution for critical infrastructure

Securing sites operated by Industrielle Werke Basel (IWB) tests a locking system to its limits. The infrastructure company supplies residents of Switzerland’s third-largest city with electricity, district heating, biogas and natural gas, and safe drinking water. Locks must offer maximum security, as well as stand up to freezing temperatures, heavy rain, and solar radiation.

For IWB, the answer was CLIQ® from ASSA ABLOY. CLIQ® is an intelligent mechatronic locking system that combines the best of mechanical security and electronic access control. Users are issued with a single, programmable key that enables them to open just the locks for which the key has authorisation.

Power for communication between key and cylinder comes from a standard battery inside each key. There’s no mains power line to the cylinders, which means installing CLIQ® system needs no wiring — a big advantage for any public utility with lots of remote or outdoor openings.

Precision mechanics inside every CLIQ® cylinder guarantee durability. CLIQ® cylinders are compliant with EN1303, EN12320, and EN15684 — and so offer high levels of protection against physical attack. They are IP rated, waterproof, and ATEX approved for use in potentially explosive areas.

“We’re convinced of the benefits of CLIQ®,”

says Thomas Hug, project manager at Industrielle Werke Basel.

“Public utilities really push locks to their maximum,” says Christoph Oberle at ASSA ABLOY Switzerland. “Critical infrastructure sites are usually dispersed, and often outdoors — so locks must be reliable in all seasons. That’s why we precision engineer CLIQ® technology to the highest standards. CLIQ® can weather whatever nature throws at it.”

CLIQ® is also a practical and time-saving solution. If an employee or contractor loses their key, it’s straightforward for system administrators to delete its authorisation using the CLIQ® Web Manager software. Thanks to CLIQ®, IWB can wave goodbye to the expensive refitting of cylinders every time a vital key goes missing.

CLIQ® is a high security locking system with high-end microelectronics, programmable keys and locks. The system offers a variety of combinations of mechanical and electronic systems to match different security and flexible access needs. Available on the global market place, it provides flexible access and key management solutions for all kinds of locking applications. CLIQ® Remote solution is designed for distant sites, enabling the commissioning, programming and full administration of security management centrally via web-based software.

Founded as a private gas company in the 1800s, Industrielle Werke Basel (, or IWB, is now an independent utility owned by the city and canton of Basel. It employs over 750 people, and supplies around 190,000 customers in Basel and north-western Switzerland with electricity, district heating, biogas and natural gas, energy services, telecommunications and safe drinking water.
