changing the key battery

[basssman]

Hi all, this probably has been answred before but I can't see the relevent post.
Can someone tell me how to remove the battery in a all plastic key from a W210 320cdi 2000. Do you have to reset anything? etc.

No reset will be required.

Remove the metal blade section, there you will see a little white tab where the blade goes at the top. push that in with a very small screw driver and lift the very top off the key and all the gubbings will lift out and you can change the batteries.
