Key fob not working

[Khal123]

Hi all,
Sorry if this is in the wrong section.
I am not able to unlock my car (c180 2004) using the key fob. It worked fine up until a few days ago. I have changed the batteries in the key fob, the number 8 fuse is fine and sometimes it will unlock if I hold it under the IR in the driver handle.
Any help would be most appreciated!

Well the key may be shot but take the new battery out and make certain that the contacts that are on the side of the battery are touching and have not moved down away from it.

I've checked the connections when I replaced the batteries and tried the spare as well (as it was dead). The radio works fine also. Do you think it might be the main battery in the car on its way out?

Probably the receiver unit has failed.

Wheres that and how would I replace it?

First, check fuse Number 8 in the rear SAM.

First, check the fuse.

Checked the fuse already and it is fine. It will unlock/lock occasionally when I hold the key under the IR receiver on the driver door handle.

Then it sounds like the remote antenna unit has a fault.

Usually fitted to the upper part of the left rear pillar area in the boot.

Touché. Was hoping somewhere like eurocarparts or someone might do them as well although I couldn't find it when I searched

No problem,

Just search on Google, some MB Parts Depts sell on eBay, or ask Steve Jenkins at MB Edinburgh for a quote, he can often discount stock parts. I saved over £80 on brake pads and discs compared to my local dealer.
