Lately, I noticed the horn will beep twice on my 05 XJ8VP when I turn the ignition to start the car. The FOB works perfectly as does the car. Just wondering what causes the 2 beeps? I don't recall the car doing this until recently!

First thing to check is that you're not inadvertently pressing the lock button on the fob as you start it as that will give the two chirps.
