SL55/63/65/R230 AMG: Starting an SL55 with a flat consumer battery and keyless go?
I am new here. My brother has lent me his SL55 for a few months while he is away. It took a few weeks for the insurance to come through, and in that time the battery in the boot went flat. He only left me with the keyless go card, and I can't start the car even though the starter battery is fine. Worse, I can't open the boot to charge the battery. I assume the lock is electronic.
I have done a bit of research, and it seems that with the "proper" key I could start it, but that the keyless go system runs off the consumer battery in the boot. My bro' is somewhere up a mountain in foreign parts so I can't get the key very easily. Does anyone have any suggestions of how I could either start the car or open the boot? Otherwise I have a very expensive high performance sculpture, which isn't really what I had planned.
Any help much appreciated!
Cheers
Rob
