So, you say you need a "keyhole"...well we understand. Keyholes are like donut holes; they do exist and they are sold separately. Technically, I guess these are keyhole "covers", except they do not cover the hole, they just surround it. Terminology is always so confusing. "Escutcheon plate" is the two-dollar description. And that's my "hole" story (thought about it and couldn't resist).
We have had many of these locks perfected (very compact and durable) over our 30 years in the cabinet making and supply business. We have sold and supplied parts for literally MILLIONS of cabinets, these are high quality parts.
