Lost keys dead battery how do I get in my car ?
Give the dealership the VIN number and ask them to get you two keys and fobs.
Get under the engine and connect a battery charger positive to the starter motor Red power wire, and the negative of the charger to the body.
Then call the locksmith - auto electrician - alarm installer back and ask him to register the key to the anti-theft system.
Then with the battery charger still connected, put a new fully charge battery into the vehicle.
Job done.

Where is the alternator fuse located on a 2006 BMW 330I?
If the alternator is charging the battery it will not be the fuse. The alternator would simply stop working if the fuse has blown.
If the battery isn't holding charge you might have a power drain somewhere in the vehicle. Something in the electrics may not be turning off correctly and draining the battery. Do you have any warning lights on the dash? Have you access to an OBD2 scanner to check for any Trouble Codes?
If it is a power drain the simplest fix is to get a good Auto Electrician to check the vehicle. Finding a power drain or an electrical short can be a real pain in the tail bone job because there is so much electronics on a car. Paying an expert to do it is a lot quicker and easier as they have the right tools to do it.

If it does it again, you swap the coil pack from Number 4 to Number 1. If the misfire them moves to number 1 you know the coil pack is the issue. Sometimes just moving it will fix the issue as the connections get remade.
