I have a 2006 BMW X3. When I lock the doors, from my remote lock, the lights light up, but there's no sound. Is there a way to change the preference where there will be a sound when I lock the doors?

The X3's remote is not a real alarm. It's only keyless entry, hence there's no siren or beeping when locking the doors.

u gotta do those changes from the settings option. now it depends if u went fro the default bmw remote lock or u bought it externally.

It's default. There is no way that you can make it beep. Even my X3 has no sound, only lights. The only way to make it beep it's with an aftermarket remote/alarm.

There must be a way. I have the X3 2006 BMW and when I bought it it made the sound. Then one day, no more bleap sound.
