BMW012 1 Report post Posted November 26, 2010 My E30 has an alarm with keyless entry. Alarm is working fine but it no longer unlocks or locks the door with the button push now. I hear a little grinding noise, like something is trying to unlock them but fails. Any ideas? Cheers, Rick Quote Share this post Link to post Share on other sites
BMW012 1 Report post Posted November 26, 2010 Update, found what was making the noise. A small black box located below the front right speaker. Do i need to replace this or is it something simpler? Rick Quote Share this post Link to post Share on other sites
