Replaced Battery / Check engine Light / Remote Key Problem
yesterday I replaced the battery after it died....jumped it once and couldn't be jumped again, so i replaced it.
the new battery works fine, so no problem there.
now I have a check engine light thats on and the remote key will not unlock/lock my doors. I have to manually open the door with the key.
additionally, i have played with the gas cap without any results.
any reason why the battery replacement caused the remote key to not function as well as the check engine light to come on?
