Seat. Latching it back down.
 

Have recently got this honey. :D

Am on my way to removing the tank. Finally got the key to work/remove seat
But when I want to replace the seat, either the back goes down properly(2 latch) or the front thingy goes into its slot. :shrug: But never both.

Any advice much appreciated. Thanks in advance <VBS:>

Pretty late reply, but in my experience you need to first make sure that the front thingy goes in its slot, and then jigle around to get it to go all the way in. You also may need to turn the key once the read goes onto its lockhole. Try a few times and you'll get a hang of it... kinda...
