I just bought a RX300 Silversport yesterday. The remote wasn't working when I got it so I went to Radio Shack to replace battery. Remote was working fine. While I was tinkering with it in the garage, the panic alarm started to go off everytime after releasing key. It stopped after I finally removed the remote's battery. I thought the panic button was stuck but it seems to click ok. After looking at some post, I'm noticing that some programing may be involved. Any suggestions?
