key recognition

[martyz]

Hi, could someone please confirm for me the following;
I have a w202 facelift with the electronic key, when I put it in the ignition slot it makes a "shuck" noise once, turn key to position one and dash lights come up.

question is, I seem to recall getting the noise twice when it recognised the key,as I am getting starting problems (start then dies),want to eliminate key.

cheers.

only once.

Does it do the same with the other key (assuming you have two keys)?

I've had similar issues with my W203 and have since had my EIS replaced. No longer have the issue. Only seemed to play up in the mornings and when it was colder.
