Changing from beep to horn when locking
We have a 2008 Lexus RX350. We prefer the horn over beep to notify us the doors are locked. Can we change this or does the dealer have to do it?

You could change it but it would require some wiring. There is a white wire in the drivers kick panel that you could tap into. It shows + when the beep activates so that wire would need it to run a relay to switch to a - input for the horn. The beep would in turn make the horn honk for both lock and unlock. But it would also make the horn honk when you open the power liftgate which would be two somewhat long honks. It would also honk the horn if you lock the car with a door open which would be a looooonnng honk!

There is also a third security horn. It doesn't honk when you press the horn from the steering wheel. It only honks if the security alarm is going off. It is buried in the engine compartment and difficult for thieves to disable without actually opening the hood thus setting off the alarm.
