I have taken a small diagonal pliers and un-crimped the cover no more than necessary to get it off. WD-40 is what I use to lubricate the mechanism, put the cover back on and carefully re-crimp the cover. There are better lube-cleaners, but I can't think of any right now. 50 years ago I used TV Tuner cleaner.
