there should be two bolts behind the passenger seat, take those out. pull the strap on the passenger seat forward and pull the seat back. after you take the passenger seat off you can see the bolts for the front seat, take them off and back the seat out of the lip.
Bit of a hassle, but I think I would take out the back seat, you could then slip something between the door and the frame and flip the child lock. Look at the other door to locate where the lock is in relation to the door. If this doesn't work, with the seat out, you should be able to remove the door panel and gain access to the lock from the inside and open it .
Take the key to motorcycle, insert it in the seat lock on the left side of the motorcycle, under the seat cowl, unlock lock, lift seat up and pull seat out.
Insert the ignition key into the lock cylinder below the tail/stop light. Turn the key while gently lifting up on the rear of the passenger seat and lift it up and forward nose down The riders seat can then be lifted off from the rear, up and forwards. To lock it back on, the rides seat needs to align on the two ribbed rubber barrels and pushed forward a bit. Insertte passenger seat nose down then lower the rear until you hear it latch down.
Could be one or more of the load cells under the passenger seat have gone bad. Just a guess. Take a look and see if you can see wire damage under the passenger seat.
Take te child lock off of the door
Take the seat off by unbolting it from the floorboard. Take the seat and the broken piece to a welder and have them weld or braze it back in place.
i dont care but i think you can
their are 2 clips that hold the seat in so what you do is to get behind the driver seat and push the back seat far back as you can and then pull up and repet on the passenger side
Replace it or take it to service
