Thank you for allowing me to help you with this concern today and am sorry to hear that this is happening. I will have to ask you a few questions so that I can get a better understanding as to what may be going on with your Lexus.

Do you know how old the battery is?

When you press the horn, does it sound loud like it normally would?

Customer: replied 3 months ago.
No horn
Customer: replied 3 months ago.
I bought car used from dealer a year ago.
Expert:  Genchi Genbutsu replied 3 months ago.

Ok, it really does sound like the battery is bad (possibly a bad cell). Have you tried to jump start it?

Customer: replied 3 months ago.
Not yet.
Expert:  Genchi Genbutsu replied 3 months ago.

Ok, you can try and jump start it. It not work 100% to get the car started if the battery is that bad but of you do and then the horn makes a sound or the headlights can come on, then you know for sure that the battery is bad. I personally would just install a new battery as this is what we see most often.
