Electrical issues

I needed a jump start on my car recently, and now the 2 rear doors wont open or lock with the key (only manually) and the 2 front electric windows wont work, do you know why?

You must have damaged the locking ECU. Maybe moisture in it caused a shot while the battery was being jumped.
