I have just bought our 06 Patrol and can anybody tell me what to do when the rubber wears through on the key actuator. Keys work in ignition etc, so dont need to replace either half, just the rubber press piece. Actually I think one "open" pad has worn right through and wrecked the curcuit board click part on one key. Do you just buy the head and get them recoded from Nissan? (surely thats the expensive way) Any help appreciated.
