I just bought a 2013 GS 350. When I lock or unlock with the key fob or touch the handle, I hear both the usual electronic beep AND the horn beeps once or twice (depending on if I'm locking or unlocking). Why both? How can I turn off the horn? It is too loud in my parking garage.
Does everyone's GS do this? I didn't notice this on my test drive.

I have never heard a GS honk after the beeps...it should only beep when looking or unlocking. You might have an aftermarket alarm system or something.

To be clear, the honk and the beep happen simultaneously. I can adjust the beep volume level in personalized settings but don't see how to adjust the honk.
It is certified so I don't think there is any aftermarket items on it.

When i unlock or lock my car there is absolutely no horn beep (just the usual sound from unlocking and locking). Mine is a 2015 and its a Canadian vehicle not sure if something changed or perhaps the dealer disabled it prior to me purchasing but I've never heard a horn beep in the 2+ years I've owned the car.

I don't think the horn sounding is normal. I'm wondering if the previous owner had it done...

Just to follow up...
There was an aftermarket alarm on my Lcertified Lexus that was causing the horn to sound when locking, unlocking, and just walking near the car. Lexus dealer initially said they wouldn't touch it but after talking with service manager about how this was a certified car that shouldn't have aftermarket stuff, they did remove it for me at no cost. I am happy that I just hear the usual Lexus beep now...ahhh.
Now that I've driven the car about 10 days, I am falling in love with how it drives. I traded in a 2007 LS 460 for this. The GS 350 is smooth as glass at highway speeds and a thrill to drive on a twisty road.

Smother than your 2007 LS 460? Is it quieter than your 2007 LS 460?

I figured an aftermarket alarm had been installed by the previous owner. Glad you got it taken care of to your satisfaction...

You may be asking the wrong question, I would want to know what was installed. I doubt it was an alarm, sounds like you had an aftermarket remote start. Those systems are integrated into the factory alarm so that you can use the key fob to start the car. Did you ever hit the lock button three times? Something tells me if you did the car would have started.

I did try many combinations of key fob button pushing to see if it would remote start because I considered that possibility. All I got was lots of horn honking. I would only want a lexus system on my certified car. I'd expect the dealer to tell me if I was misusing a Lexus option. Instead they told me it was aftermarket and they didn't want to touch it.
