Key fob doesn't always work

[television]

I have had to replace my batteries twice already! considering I have only had the car for 5 weeks!
I thought there was something wrong with the unit and took the car to my local mercedes dealers, they replaced the batteries in the fob and it is running fine again now.
Is this a common thing with the units.

These batteries normally last up to 12 months or more

Another member jumping in here! I have a faulty key fob (fortunately my spare) that works in the ignition and therefor will start the car and allow you to drive, but the red light doesn't light up on pressing either button so the locks and alarm can not be operated. (Brand new batteries tried and makes no difference). Two working keys would be better for me as my partner sometimes comes for the car when i'm out, and I prefer to always have my keys with me... Mine is a W203 estate, so the 2 button key with slide out emergency key.
I was considering buying a similar fob on eBay and trying to make one good fob out of two, think i'm probably wasting my time though, any thoughts anyone? anything to avoid the £220 the stealer want's for a new one! Any suggestions as to the fault here? I know how to get the key to pieces...

You are welcome to to send the key to me and I can check it out for you

The first set was from the post office, the next set was from Woolworths (which is like Sainsburys) and the last set was from a digital printing photo store. They are all Energiser batteries. By the way I put in another set of batteries last night and resynchronised the remote and it is working normally again but am afraid that in a few days it will start flasling red and green again!

OK after putting in yet another set of new batteries in 2 nights ago, the flashing red and green has come on again (simultaneously)! They are energiser lithium batteries and when I press once on the key in the middle of the remote, a red light flashes in the sensor - that is supposed to say the batteries are fine right? So what's wrong and why does it keep flashing red and green at me - I'm going crazy!

You must have a faulty component in the key fob causing excessive drain

Malcolm can you please respond to this and let me know if you are in possession of my keys or not?

I am also resending the PM I sent last week.

I am sending this again because it looks like you have missed it as I can see you still posting online everyday...

Thanks.

Your own key has the broken transponder coil and new ones will be wound shortly.

The other old key is of no use to this nothing is the same on it
