Does anybody know if you can upgrade the 2003 card keyless go to the new 2004 keyless go integrated into the key itself?

I have been told no from several sources. I am still looking into this but it seems that MB will not replace Keyless Go Smart Keys for any vehicle that was not originally equipped/produced with such.

That seems to be the snafu.

i heard the same thing

Why in the world would you want to?

Leaving aside the metal key backup issue, you lose the ability to check the lock status of the car. Only yesterday, I suddenly worried in a restaurant whether I had locked the car. Press the button, green LED. Yikes! The car's unlocked. Out I went, and, sure enough, the car was unlocked. Very useful feature which you guys with only smart keys do not have.

awiner

True ! And one of the great features only available on the card version of Keyless Go. Now if only they would have had a place to insert the metal key on the card.....

blueSL

It's been done before. My SL600 has a card more or less the same size as a Keyless Go card which is both an infrared blipper and metal key. It's 9 years old, so you'd think with the advances of electronics that integrating all the functions into a card would be child's play.

How about the other way around. When I get my new 2005, can I replace one key with a card?

blueSL

Unlikely, they dumped the card to stop complaints from customers who couldn't get into their car with the card alone - a flat battery in the car, a flat battery in the key card or radio interference swamping the card/car communications. With the smart key, you have infra-red backup and, if all else fails, a good old-fashioned piece of metal to get you in.

jeffreyy

Yes, but I'd rather carry the metal key from the smart card in my key case and put the card in rather than have a big plastic key taking up all the space in my key case.

oh, what a cool feature with the card function, letting you know if you locked the car

does any one know why the present keyless go setup does not have that function - ?economics

i would like to bring this question back alive. has anyone updated the 2003 card keyless go style to a 2004-5 carry key with keyless go. is this possible? the cards will not get you into the car if you do not have a key with you and should carry the key anyway as a backup.

As of now, nobody seems to have a definitive answer to this question I also asked it in the AMG owners forum that had a previous thread on the subject as well.

Until someone tells me otherwise I'm assuming that it's not possible.

I had my first 'experience' with Keyless-Go on the second day I had my car and went to show it to a friend. When I turned off the car that was it, the car was completely not responding to the card. We had to drive in his car to my house to get the regular key. I asked MB and they said that especially around the local airport Keyless-Go failed a lot. Why it was refusing to work at my friends house is not clear to me. Maybe a wireless lan?

I'd like the reverse, to have one of the flat key cards to carry around. It fits into my key holder better than a big SmartKey. I found this document a while ago on the net. It's too big to upload.

BTW, I don't think that it answers your question about the SmartKey vs card key. It simply details procedures for coding a fresh key in the event you lost yours etc. It might be helpful to alert the dealer to the presence of this publication.

This file and a lot of other interesting documents are available here: http://www.mercedestechstore.com/pdfs/

Thanks for the heads up - lots of interesting stuff. It's clear there's much more to Keyless Go than meets the eye.

Also interesting to see from other documents that if you have the "Electrical Consumers Offline" message which switches off non-essential items, you can close the roof but not open it. If it's pouring with rain, closing the roof moves up the list of priorities...

jeffreyy

Yes, that is a great archive! Thanks for telling us about it! I particularly liked the part about the MOST bus. It would seem that perhaps the audio gateway could be changed to give yourself Logic 7 or other alternative audio system although given that it is the bus master, it would take some guts to make the move!

Also, it would seem that with MOST, the door may be open for some nicer accessories such as DVD Players or the much anticipated Bluetooth!

For grins, look at the MOST bus diagrams for the Maybach. Whoa!

it seems that if the card fails, then you must have a key to get into the car and to start the car. carrying the card only will not always be the safest way to travel. i was just carrying the metal key insert, from the key, as a back up but realized this only helps with access into the car. you cannot start or drive the car with just the metal key insert. so, if your card fails you have to carry the entire key. therefore it makes more sense to have the keyless go in the key. that is why i was asking about upgrading to the new key system form the card.

jeffreyy

No way! Well, that is great info. I will not pursue the flat card after hearing that info.

Correction: But our cars locks the doors automaticly, so no need worry about to check oh did I forget to lock the car, if the key is outside car it will be locked after 2 or 3 min.. so yes we do have that feature called: We do not have to worry it will be locked

way to bump a 10 year old thread

KAROZZA

Well, in the spirit of the revival of an old thread, I bought a new key/remote for my 2002 SL55 about 18 months ago. At the time, I requested the Keyless go incorporated in the key but MB told me that they can only order what originally came with the car when new. In my case, I have a Key Card with no key or remote incorporated which I find very convenient, especially in summer with light clothing. But, I live on a tiny Island & when I do travel to mainland Europe with the SL, it feels safer to take a Key/remote for peace of mind.

Thanks bro very useful I also found the same on mine actually the key-card was tugged away in the folder that came with the car I just didn't see it lol so problem solved, oh and got new key with transmitter so now I have both options just had to re-program and voila...

?
was that a qualified guess or a clueless answer?
