Description The TK5561A-PP is a complete transponder integrating all important functions for immobilizer and identification systems. It consists of a plastic cube which accommodates the crypto IDIC e5561A and the antenna realized as tuned LC-circuit. The TK5561A-PP is a R/W crypto transponder for applications which demand higher security levels than those which standard R/W transponders can fulfil. For this reason, the TK5561A-PP has an additional encryption algorithm block which enables a base station to authenticate the transponder. Any attempt to fake the base station with a wrong transponder will be recognized immediately. For authentication, t...
