Ha,Ha...

Sorry bout all the posts, but only just bought this car & have so many questions..

I have been given 2 Electronic keys with car, but even though both lock/unlock it...only one will start it/turn?

Both led's seem to light up on keys but, is there some sort of knack to get the other working?

Thanks...

Alan.

Hi..

I tried that this morning, but it doesn't even turn or click when put in the ignition switch?

Tried hitting the buttons whilst in the ignition aswel..just does the doors..

Any other ideas?

Thanks...

Leave it in the ignition overnight if safe to do so (locked garage). Quite a few posts on the forum whereby the transponder has to be recharged in the ignition if it is not used for a long while (~6 months). If then it is still not working then a trip to the MB dealer maybe in order.
