Cluster lights

Don't have an answer for that. I can tell you how to get the cylinder out but I've never had one that wouldn't give you the key back. I can only suggest you try rotating the key slightly either way toward "on" and "acc".

You might try wiggling the key up and down too while you pull on it. The tumblers aren't the little round two-piece pins of the past. They use rectangular pieces of metal with rectangular slots in the middle offset varying amounts. Perhaps one of those pieces is corroded or bent.
