door - locks .

I have a 2007 Z4 coupe that the door - trunk lock will not respond unless I am close enough to use the key . Has anyone have had any experience with remote battery replacement , range extenders or other fixes ?

For a no-cost range extender, hold the key with the blade pointing upwards and bring it up until it touches your chin. It looks goofy but you will be amazed as to how much further away your key buttons work.

I replaced the original rechargeable battery with a new rechargeable battery . Do it yourself brain surgery would have been easier . Door lock distance has improved , but trunk unlock is still vague . Alarm does not work at all .
