Keys and Keying

All ASSA keys are manufactured from the highest quality 

nickel silver material. The key’s rounded back facilitates 

smooth operation and minimizes wear. The large 

key bow simplifies identification and use by 

manually impaired people. Keys can 

be provided with various options of 

tactile identification upon request. Available 

in several profiles or broaches, ASSA high 

security keys all feature a unique side milling 

on the lower portion of the key blade and are precut at the ASSA factory. Each side

milling represents a key section that is factory controlled on a geographic basis

providing an unmatched level of patented key control.
