Thanks to Corfire who did all of the hard work and research, I performed his "chirp" mod for the keyless entry. It works great! I used a 90db, 2.8k hz buzzer and it works well. If anyone is interested and likes my setup, I would be more than happy to fix these up for you when we get together. If you're interested, no obligation, just let me know and I'll get enough materials in case you like it. I can always return unopened buzzers at radio shack. I will attempt to load the sound files so you can get an idea of the volume.
