so you're now trying to bend something because that might be the right thing to do but you're not sure? seriously, just take another one off, they're designed to come off so you can get out the biscuit crumbs you drop under them. once everything's in the right place the keys just pop back on.
Don't worry no bending was required. Its back on but a bit loose.
They may be designed to come off but it takes forever to get them back on.
