Project Big Six-y: 1991 BMW 535i/5

[Jake]

just a heads up - i've heard of GM ignition switch barrels failing, due to some soft metal inside, but to some degree it's made worse as a result of having alot of weight hanging off the key. it contributes to odd wear patterns inside where the tumblers are. i noticed you've got some flair on your key (and we encourage that :lol, and that may be something to think about if it has some heft to it. then again my wife has a keychain that looks like it belongs to a janitor and could double as a swinging mace, and her car has never shown issue.

I've heard that excessive weight can be an issue. I think here it's just a 20-year-old part... my keys are pretty light compared to many peoples' (BMW key, Miata key, apartment, mailbox, bottle opener). I'd split the two car keys apart, but they're both just steel - no remotes, chips, etc.
