I agree. It is probably best to replace it all in case you nicked some other part with the drilling. I suspect it was TriMark and your new key number (located right under the black top is the same on both). They really rely on the deadbolt for security.
Glad to see you got it fixed. When we locked the keys in our coach we called a locksmith to open the TriMark lock on the handle. It took him all of about 3 minutes to do the job. We only use the deadbolt now the key to which is always on the key ring.
