I just notice that this happen to me.. I have 2 remotes, 1 remote makes sound when I lock/unlock my car and the other doesn't and I want the sound in order for me to know that the door was lock/unlock.. Any clue guys????

Thank you guys

 

Hold down the trunk and lock buttons at the same time and that will change it back and forth.

 

hey it works!!! Thank youuuu so muchhh

 

 

Jamz, you da man! I was always too lazy to look up how to switch between chirp and no chirp. I tried lock and unlock, but that didn't work so I said f it. I think my neighbors will be much happier when they don't hear me in the middle of the night now
