Hi everyone -
My girlfriend recently purchased a 2010 Mazda 3. The power door lock beep doesn't sound when hitting the lock button on the advanced keyless transmitter. I've looked through the manual, but cannot find out how to turn this feature back on. Anyone know how? Does it have to be taken to the dealership?

Thanks in advance

 

press it twice & the horn will beep, think that's the only audible option.
