81971006491 Lock Set with Transponder

Complete door lock set with integrated transponder key for MAN trucks, buses, and vans. Includes all mechanical lock cylinders plus the transponder key required to authorise engine start via the vehicle immobiliser. The transponder communicates with the immobiliser control unit during key insertion — without a matching signal, the engine management system will prevent starting even if the mechanical key turns correctly. This set covers door locks, ignition barrel, and the coded key in a single kit, making it suitable for a full security system replacement following theft, key loss, or lock cylinder wear. Replacement requires programming to link the new transponder to the vehicle's immobiliser — this must be performed using MAN-CATS diagnostic software and cannot be bypassed. Designed for MAN TGA, TGX, TGS, and related platforms. Retain proof of purchase: dealers and workshops may request documentation when programming transponder keys to prevent unauthorised duplication.
