Dbcrd 92 Report post Posted December 23, 2020 (edited) Someone opened one in the attached post. They look like batteries with spot welded connectors on. By the way, mine does not chirp. Trouble with reading posts on this forum is it makes one find problems they didn't know they had and were blissfully ignorant of. https://www.bimmerfest.com/threads/no-chirp-alarm-not-working-sorta.529609/ Edited December 23, 2020 by Dbcrd Share this post Link to post Share on other sites
