Hi all,

I have a 2003 ES 300. When I lock and unlock the car via the key fob, the beep (twice for unlock, once for lock) is rather quiet. It's audible if I lock/unlock my car in a quiet setting, such as my driveway; however, anywhere else the buzzer sound is simply inaudible, which is a bit of an annoyance if I cannot find the exact location I parked. My mom had a 2005 ES 330 - same car only this was the ES after the "mid cycle refresh." The alarm buzzer was much louder and is the exact same sound Lexus uses today on their new vehicles. The buzzer sound on my 2003 is a very high pitched beep sound. Anyway, my question is, is there a way to buy a different and louder buzzer - such as a used buzzer from the 2005-2006 ES 330 which has the newer buzzer sound? I'm not looking for an aftermarket buzzer. I have no problem going on eBay and buying a used buzzer from a Lexus or Toyota, I just need to make sure it will be a simple plug and play. If it is not that easy, then no big deal - I can live with the quiet beep. If anyone knows which buzzers are compatible with my 2003 ES 300, any info would be greatly appreciated. Also, I am aware of the little **** underneath the steering wheel that adjusts the volume of the beep - it is on all the way! Thank you in advance.
