The 2002 lock is different. It works by a cable and not rods as per the '98 model.
Otherwise will fit as i have just converted mine. The downside is that it renders the door pop-up button disabled and instead unlocks when you pull the handle.
Oh - and you need the handle from the donor vehicle as the cable wont connect to the older version.
I could have scouted around for the '98 version, but they are hard to locate, as this as you can tell is a common fault.
But at £15 i wasn't gonna argue. Its 94 quid plus vat from Renault
