Does anyone know how to change the settings for the factory alarm? Like the volume of the beep and unlocking all the doors or just one door?

 

Your dealer can do that for you. I've never seen any posts on this site that gave instructions for the owner to make the changes -- all the posts said that the dealer has to do it.

 

Thanks for the reply Larry. I called Lexus of Sacramento and they do not know how to do it?!?!?!?

 

You need a better dealer!!! The settings are called the C-Best settings, and any dealer should be able to change them for you. There was a list of the available C-Best options posted on this site about a year ago - perhaps you can search for them. I printed them, decided what changes I wanted, and took them to my dealer who made all the changes. Apparently the dealer has do make the changes through a computer interface, since the first time I had the car in for service their computer was not working and they couldn't make the changes.

As far as I can remember, all of the things you listed can be changed.
