Hi folks,

All of the sudden, the beep sound becomes very very low when I press the remote control's door lock button. It is not totally gone, it just very low. Is there a way to adjust the volume?

Thanks in advance!

What year is your car?
Their is a volume button on 94-96 models beside the mirror control.
As you are from the states try the usa forums.

Check below the dash on the drivers side next to the hood release lever.
There is a knob which will enable you to adjust the variable volume from on to off.
It is easily shifted by mistake when releasing the hood, especially when feeling around under there without looking where your going.
Trust this info helps.

Hogie.

Thank you, I found it!

No probs Bro, if you need any more info or you would like a set of genuine Lexus ES 300 Gold badges, give me a hoot on, (bfh@slingshot.co.nz)
I have owned three of these vehicles and can supply programing details for registration and setting up of the remote central lock/unlock features on most Toyota autos if there is a problem.
Cheers, Hogie.
