Query: Multiple Transmitter Programming

I had two transmitters for my vehicle and one stopped working. This was a replacement for the broken one. The problem can in programming. The instructions that come with this transmitter are generic. I followed them and it did program the new transmitter-But my second transmitter stopped working. I had to get the specific manual for my alarm system to program both transmitters. They are easy to download of the internet. There was nothing wrong with this transmitter. And it would be virtually impossible for the vendor to provide instructions for every alarm system this transmitter can be used on. It is a great deal on a good transmitter.
