I've got one key prone to failure, too, plus work-arounds

Mind sharing your backup entry method?

Since I only have one original diamond key (with a new battery, and a bad soldering job...so it's questionable how long until it fails), and two new e-bay diamond keys (as spare remotes, after I did the initializing procedure; they came sealed, with Cr2032 batteries, but not cut for the physical operation of door or ignition...I don't think they'd work without BMW programming), I now carry the original plus a backup remote (in a belt pouch) just in case the original's solder job comes loose.

I also have a small jumper clip in that pouch, to be able to connect it to the jumper posts under the hood (via a 5-foot ring terminal harness), so I can supply power to a "dead" battery, in the case where I also can't use the physical door key. I also carry an extension for that harness in my belt pouch, for external power supplies.
