Can i change my key fob to the new Chrome version?

[s5aif]

Hi, I was wondering if anyone here knows if i would be able to change my key fob to the new version with the chrome trim. If i take out the circuit board from my current fob and insert it into the new version would everything still function? Thanks.

If it physically fits, no problems..

Where will you get the new version from?

I see a few of them on ebay every now and then. The shape of the two fobs is different so cant say if it would fit or not. The newer version is more oval in shape.

The new version has 2 batteries in as well.

Hi,
My old one has two batteries in it as well, mine is the same as the one in the link below;

£148 (inc VAT) from the main dealer. Had to take passport, log book and a utility bill before they'd let me order one.
Really stylish and rather cool. Worth £148? Maybe...

My secondhand 2004 W203 was supplied last year with one old style all black plastic key and one new style chrome key. No prizes for guessing which one is the spare sitting in the drawer at home.
Only downside is that the chrome key is quite a bit heavier.

The PCB cannot be changed over as the buttons are not in the correct place

Quite correct. Non-interchangeable.
For proof, see attached scan........

Thanks for the comments. So if i was to order a new spare key would i be given the new version or would i have to request this. Probably wont bother ordering one until/if i lose one of my keys.

I think MB only supply the new chromed key now. I didn't specify either, and I got a chrome one. That was about 6 months ago.

This would be correct as they had to get rid of all the old type first

Does anyone know how to open the keys to look at the gubbins inside?
I thought I would actually open my 2 up just to check and make sure 100%.

I've just dropped my car in for a service and the loan car is a C180 that has one of the new key fobs, I'll will admit it feels a much better quallity product than the all plastic type.

Take out the key, take out the battery and you will see the PCB that slides out

 

[verytalldave]

Pardon my obvious ignorance - but how do you take out the battery? I have removed the keyblade, but I cant see how to do this. Sorry to be a pain.

Use the end of the key and press the white thing in the side and the whole top comes off

Thanks very much for both your help and patience Malcolm. However, while your instruction above works for the old style fob, it doesnt for the new chrome one.
The new chrome one has a small black plastic lip which needs to be pulled over. You cant use the key blade as its too big to fit in the gap. You have to use something smaller, like a ball point pen tip for example.
However, I do have both keys in pieces and I can confirm 1000% that the PCB is non interchangeable between the old and the new. It is a completely different size and shape. Also, the old fob has only one battery, whereas the new one has two.
So there you have it.
One further difference is that the keyblades themselves are non-interchangeable.
The blades have different shaped retaining grooves.
