You'll have to remove the old cord and attach a new one.
Not difficult, but you need a 15 - 20' cord.
Don't try butting the ends of two cords and taping them
together. Not a good idea.
Or -schlep it to your local hardware and have them do it.
If you're not a true-blue DIY type, this might be the way to go
