This video shows step by step how you can open the trunk of an E88 BMW after you accidentally close your trunk after disconnecting the battery. Since an E88 trunk latch works requires a power supply and there is no key slot it's a little tricky to open the trunk with no power. But this video will allow you to open the trunk within about 15 minutes. So, don't despair [like I did] if you find yourself in this situation.
