You may simply need to synchronise the key to the car. Lots of posts how to do that here. IF YOU NEED TO REPAIR IT hen instructions here. repairing broken W202 Key fob. - Mercedes-Benz Owners' Forums

The instructions for resyncing the key are here http://www.mbclub.co.uk/forums/electronics/26218-96-w-s-124-e200-remote-central-locking.html

BUT if the red light LED is not working with new batteries [ right way round?] then the key is probably broken and will need repaired. Replacements aren't cheap and can only be ordered from MB.

Repairing it yourself isn't easy if a contact is gone. I ended up soldering mine (and had never soldered before.

Make sure the contact really does press down on the battery with the cover closed. You might want to wedge something between the top of the contact and the plastic cover (like a fodled bit of paper) just to make sure it presses down. Be careful if you think you can bend the contact - it may be work-hardened like mine was (and it ended up snapping off).

there is another access point on the boot on the estate, i used to open the estate from back, i realise the actual unit is not working, but sometimes the one in the door handle go busted, and that is also is expensive to replace

NOPE the remote is only to do with the remote locking. Just see if it locks unlocks the doors remotely.
