Ok, I have the same problem. The door wont open cause the battery is dead. There is no key entry on the passager side and you can not open the hood because you have to pop it from the inside. So.... What are my options at this point??? Any answers?

Hi TOM, Thank you for your infinite wisdom, however, your logic is severely flawed. You assume all door have a mechanical lock, when in fact many newer models only have electronic locks, hence my FREAKIN DOOR WONT UNLOCK!!!!!! Don't you think I would have tried the key you JACKASS!!] If you didnt already guess, I am having the exact same problem with my nissan 350z, the dealership told me to have it towed there and they can remove the engine pan to expose the trunk latch where they can open the trunk and charge the battery.

I didn't see what year model in description, just 7 series. I know with the E32 chassis, which the hood is hinged from the front, you can use a metal coat hangar and bend a sharp hook at one end and straighten out the rest. Used it to grab the cable that releases the hood latch. Get the hooked end around the cable housing and give it a little pull and it should release.

We had this problem here at the used car dealership I work at. We had a locksmith trying everything to get it open then I had the idea of getting a long lock-out rod to open the hood latch inside the car. He brought a longer lock-out rod- kit and opened the hood, connected a battery booster and used the unlock button on the key and vualla, the doors all unlocked. We put a new battery and I had the idea to put a secret hood latch sting in the bumper to open it from the outside if it happens again

So yeah, the same thing happened to me on my BMW 328i just three days ago. It took me that long until I figured it out. Some vehicles, in order to lock it you have to lock the door then lift the handle as you shut it close in order for it to lock. Thinking of this I used different variations of that theory on my BMW. What you need to do is go to the driver door, lift the handle first then insert the manual key into the lock and turn clockwise. It may feel a little tight as you begin to turn the key but you'll feel it turning. Remember to follow the exact sequence that I gave you or else it wont unlock. 1. Lift the door handle. 2. Insert the manual key. 3. Then turn it clockwise. And for those of you who don't know you can find the manual key inside your key FOB. There should be a square button on your key FOB. Press it and pull and there's your manual key.
