WELCOME. You are spot on with CH751 for the finger latches, the key for the paddle latch is CH745. The cylinder lock for the coolant door (on my 567) is C415A, if you want a copy let me know and I'll make one. I'm pretty sure the alarm key switch is made by Cole Hersee. My key has IC047 stamped on it. You can find Cole Hersee products on line if you desire changing, it is a simple on-off contact arrangement.
