Key loss of a Trillium?
...When a door key is lost, someone might add another latch with lock which alters the original exterior of the trailer(such as my case). Solution is simple, unlike what I'd been through, trying to relocate new latch or even align the door to go with it. Here it is: Unscrew the old latch(with 2 screws) from inside. Carefull pry it off from outside with a flat head screw driver. Finally bring it to local locksmith to make up the key. He/she would be able to make...TEN keys if you want. In my case, in the end, I gotto take out the extra latch, fill up total 8x2 holes for what I just found out. Here is some photos and hopefully it helps...
