I have Keyless GO and the battery was drained. I had to open the door with
the little metal key that goes into the Smartkey. I then opened the trunk
with the key and jumped the battery. After a few minutes of charging from
the jumper I was able to use the Smartkey to crank the car. The Keyless GO
would not function however.
I have run the battery down twice because the Xenon lights were left on. I
would think that MB could put a chip on the battery to shut them down when
reserve goes below a prescribed level. I guess that would be to much to ask
however. I just put a jumper box in my trunk to prevent this from happening
I always believe MB should make a car smarter than MB's engineers. A smart
battery would definitely a good point for an expensive car's standard
Recently I found some Japs car's design has nearly overtaken German's. Look
at a Lexus GS 300, I would ask myself why my C-class doesn't have this
doesn't have that.
Yes. The ignition switch socket will induce the necessary power for either
the standard Smartkey or the flat (no-battery) wallet key (spare) to work.
The only thing the battery is really needed for is to remotely open/close
the doors, trunk, etc.
IIRC, while the code changes with each use (and each key), the car's program
is allocated a block of 8 key identifier codes. If a Smartkey is lost or
damaged, the replacement is based on the remaining identifiers available (as
you want to remove the "lost" key's ID code from the car's program, so as to
prevent a rogue "finder" from using it to access the vehicle). When all 8
identifiers have been used, another block of 8 must be allocated.
