'97 E300 - Infrared Sensor Troubles
The infrared sensor on my driver-side door works intermitently. The green LED actually looks a lot less green. Is there anyway to clean, replace or seal this "assembly". Maybe the LED/sensor can be replaced?

i have to be about 2 feet away from the door for it to unlock, and yes the batteries are good.

We've had a lot of rain here yesterday. I have a feeling that moisture finally started getting the best of it. I've noticed that with strong batteries, the range improves.
How do you know you batteries are good?

NOW what the heck can I do in regards to my problem?

If you mean the plastic cover on the key, yes, but... not just that piece of plastic. I bought a used key on eBay and took the innerds out and replaced them with the one from my key.

same problem
I have the same problem with my driver side door sensor. It is complete cracked from stupid valet drivers shoving the key in there. Dealer quoted me in the 300's I said forget it. Since they are programed for the car- no used parts either.
I can live without it for another couple years until my C350 ;-)

I know the feeling, same thing occurred on my driver's door due to the clueless valets in SoCal. It works intermittently, usually fails after a car wash or rain. I am living with it but it is a pita at times not having key access to the driver's door especially when it is raining!
