Hi,

My 2012 C220 was working fine earlier, just got into it this evening (didn't need to unlock it as I hadn't locked it earlier) and when I put the key in the ignition absolutely nothing happens, turn it through the various positions but still nothing.

Took the key out and noticed the remote lock/unlock not working, changed the battery and the red light flashes on the key and I can see the purple infra red flashes so the key seems ok. But still nothing works, neither the central lock/unlock nor the ignition.

I don't have a spare key, lost it a few weeks ago and not replaced it yet.

Anyone any ideas - car battery, fuse - I'm a bit stuck since I can't start the car?

Thanks for the reply, it was less than an hour earlier. The remote central locking has been a little temperamental over the last couple of months but I've never had the problem of nothing happening when I put the key in the ignition.

Are the wheels locked/unlocked? I say that because when you insert the key and turn it one of the 1st things to happen if the wheels are locked is that they will unlock. Anything like that happening?

Nothing at all, not even getting the noise you normally get when you insert the key. It does feel like the lock is on but it's not unlocking (or doing anything else).

Does ignition turn on at least? I had similar last week where ignition turned on but wouldn't turn over engine, ended up battery was a bit low with all the short journeys to work and no runs out at weekend. stick battery on charger overnight, can do no harm

In that case i'd lift the bonnet and tighten up the battery leads and suchlike, then see will that make a difference. Can't hurt and tomorrow bring it to someone who'll check it over. Kev555 has given good advice too and neither will do any damage
