Just two weeks ago I removed my twin-key Trimark entry door (latch with dead bolt) assembly to re-key one of the two locks to match the other for the convenience of using a common key. I selected which lock to reuse based on the spare keys available. I liked the square handle key to easily identify it uniquely from the round shaped key used for all the storage compartments. So in the end I have the van key, the square main entry door key and a round third key for everything else.
The backing plate on the backside of the Trimark lock assembly was held in-place with what looked like four rivets, but was actually hammered alloy from the main cast alloy piece. I had to drill off the four heads to remove the plate to gain access to the tumblers. After re-keying was complete, I drilled a deep hole at each of the four points, then tapped threads for screws hold the plate back on. Two of the four holes needed to be drilled through to the side that shows so the threads could be cut properly. The holes that show through are trivial to me. One is hidden by the handle. The other is in view. I was going to put a dab of black paint on the hole but can't find the motivation yet to pull out the black paint. It's a small silver dot that I can hardly notice.
