Your pics are not of the keyless control box - that's the window lift relay box matey -- as far as I know no JDM ever came with remote locking as standard - as its not required under Jap regs - some of the later versions 2002 onwards came with an Iszuz aftermarket add on - but you'll find that info in the trooper hand book I think

Steve - PS - there isn't much I don't know about the VX - Crotchrocket cam eot mine to have his work done lol
