My wife has gone and lost her keys walking the kids to school. Because the keys were lost near the house I am worried that someone can now just walk around pressing the unlock, find a flashing car and drive off in the Jazz. I have temporarily disabled it but I now need to replace the locks. What parts do I need to do a replacement? Obviously doors, boot, glovebox(?) locks and ignition barrel. Do I need a new ECU or can a new barrel be coded to the existing ECU? Any ideas? Other than divorce - - - Updated - - - No worries, keys have been found!
