I just bought an 05 MCS, it had only one key, but the remote does not work...batteries are dead. Where do you get a new remote without going to BMW and getting screwed? Are there any aftermarket remotes?
My set came with two remote style keys, but most folks have one remote key and one basic mechanical key and then one made of plastic which fits into your wallet which operates door lock and ignition. So having just one remote style key is not uncommon.
CR2032 is everywhere but it needs a rechargeable? Anyone ever tried just a typical alkaline? If you have an old computer that you never threw away, just take the battery from the motherboard. That should be a CR2032 :P
The 05 has a rechargable battery....
It is recharged when in the ignation....inductive charging.
New keys for an 05 have been on ebay....but good luck getting them cut+coded to your car....but you could transplat the battry from an ebay key....
