Bought the Reflection 303RLS home, dealer gave us the main door key and the CH751 key. I found a key in the storage bay, Southco LS001. Problem is none of the keys will go in the lock for the main compartment doors. The CH751 fits the front compartment where the battery is. I have tried to insert all keys right side up/up side down, won't go in at all. What do you guys with this trailer have for a key that locks this compartment, street side and curb side. Called the dealer, they are checking as to what key will work, but I know you guys have the answer.

Thanks,
