I was disappointed with that no instructions and no tool came with my order of a new remote and receiver. I had to go to two different hardware stores to find a tool that would fit in the receiver to get the screw out and it still would not budge. I had to grind down the receiver to get at the screw. I decided to try and figure out how to install the receiver on my own. The new receiver has 3 clips but my existing receiver has just two and the 3rd doesn't appear to be a clip but rather something wrapped in a sealent and electrical tape. Anyway I think that I may have ruined it and won't be able to use it at all.
