欧州におけるスマートキーシステム：Renault Laguna

Abstract

SBD' s latest security report evaluates the smart key system used by the Renault Laguna.

Renault is currently the only manufacturer to offer “Walk Away Locking” (WAL) in Europe. The system is offered as standard equipment on the top six grades of the Laguna model and is called “Hands-Free” by Renault.

Renault' s first generation smart key system was released in 2001 and was only available in LHD European markets. This second generation is available in both RHD & LHD Europe from 2005 onwards.
