Hey folks, I did a quick search and didn't find the exact answer I need:

I have a 2007 E93, no alarm system. It is completely stock, and does not beep at all when I lock or unlock it. The dealer just gave me a 2012 loaner car and it does beep on lock/unlock. I had this on my old 1997 528i, and really miss it. Can a 2007 be coded to beep on lock/unlock, even though it does not have an alarm? Is an alarm required to get the beep or does the car have beep capability that can be accessed through coding?

Thanks in advance for your help!
