Have a key that’s been twisted out of shape and don’t have a spare one handy? No worries, here’s a quick fix: Clamp the key in a vise with the twisted end pointing up. Then use pliers to carefully twist the key back to the way it should be. Go slowly and check frequently to see if the key has been straightened out.
Note: Replace the key as soon as possible—once bent, it is far more likely to shear off in use, leaving you out in the cold.
