Did a search but found nothing similar so.. as usual after my 04 FJR had stood for a long time (since September), the fuel filler was jammed. The key is normally free to turn but the catch on the bottom jams. 3 in 1 and brute force eventually opened it but the key always suffers. I was thinking of stripping the mechanism down and want to know what to expect when I remove the 2 screws from the bottom of the catch? Will it explode in many springs and lock bits or merely come off to be cleaned up and lubricated.
