how to open and change the battery of ford focus 56 reg
Get the key
Unhook your negative battery cable for about an hour. When you hook it back up, the computer should reset itself. Make sure your key is in the ignition. If not, there is a resetting sequence in your owner's manual that tells you how to mate the key to the ignition. Follow the instructions PRECISELY! You'll need an analog watch for timing the procedure, as it deals with seconds.
