I've never had a problem using the remote to open the windows but what sometimes works and doesn't work is when I use the door handle to open the windows. With the Keyless Go I have been able to open all the windows using the handle (just kept holding the open door pad on the back) then close them using the lock button. Sometimes it works....sometimes it doesn't. I'm wondering if anyone knows if there is a process to doing it?

FOB open windows
this has always been unreliable for me. On my '99 C230, it malfunctioned and I ended up with the sunroof open when the windows were closed, and vice versa. Not sure how I fixed it in the end (I think I started the car while holding the sun roof controls or something). My '06 C280 doesn't respond to it at all no matter what I do.
It is a nice luxury feature--clears the hot air out immediately, but nice features are nice only if they work.

How was it with your other key? Did you get two new keys?

thanks everyone for all the input. I'm sure it is that the handles are old and wheathered. this make sense that it would work so infrequently. i didn't quite understand about holding the lock on the handle thing though. i didnt even know that was a feature. thanks again everyone

well now that that has been mostly answered, what about this sunroof problem? once in awhile, when i go to open the sunroof, it will only open a third of the way or so. it takes a few tries. i know about the holding the button each way for 10 seconds to reset it. but i want to know what is making this stuff happen

Also, FYI - the door handle button trick is for Keyless-Go equipped cars only.

I have same problem. I haven't tried with second remote (have never used it), but I think it is the remote and not the car.

As I mentioned before, windows are control with the IR part of the key. If the IR part does not work, you cannot start the car. The key switches sometimes break (soldering) but then one could not open/close the door. What is it in the key that disables remote control of the windows but keeps the keys working otherwise?

You must have some thoughts why it would be the key and not the car? Even if one car was fixed by a dealer ordering two new keys, I would not be convinced. It can be the standard case, the keys were faulty and then there was something else too, the door handle IR receiver. Except that in this referred case the dealer had to consider which one to make the owner pay for.

Diesel, O/T question but, do you know if the frequency on the Benz remotes in Europe are 433MHz.? In the US, they give us 310MHz (it's like this on pretty much all factory OEM key systems). The reason I'm asking is because in the old days, the aftermarket alarms in the US were 310MHz. but I remember my father having to carry one unit which didn't match the rest in regards to the chip processing because it was 433MHz. (the box says European High-Frequency) and it was being sold specifically in Europe. Now, pretty much all the aftermarket ones are 433MHz here in the US too (but OEMs are still 310MHz). I just wanted to see if it is some kind of law there in Europe for that, because I think that was the reason for the 433 freq. If it is 433MHz., you guys are lucky since it gets better range.

The reason I think it is the key also is because once in a while the lock/unlock will not work. Probably batteries are old, but have to check with voltmeter. The remote is a little beat up from the previous owner (luckily they never touched the second key).

Shouldn't the US keys operate at 315 MHz? Euro keys operate at 433 MHz (approximately).

OK if you have observed problems with remote key locking/unlocking doors, then it could well be an issue with the key (both the RF connection and the IR connection failing, although the latter could be from not pointing to the IR receiver).

I've pointed at the IR receiver directly and sometimes it still doesn't. I'll try with the spare and see what happens.
