I see these smartkeys for sale on ebay and I was wondering how do I program on to work with my 03 CLK500. My key is getting worn out so I would like to replace it. These are much less expensive than the dealers so any help would be appreciated.

 

yah, i saw those aswell...for roughly 35 bux a pop im kinda scared about using them...my key is also taking a beating and its my only one.

i would assume that you must go to MB to get the key programmed?

 

I googled it and it says put it in the ignition and press certain buttons and it takes up to two hours to program. But this was for a 1998. I am not certain if it will work on a newer version.

 

Sorry x2. STFF as this has been discussed numerous times.

 

I appreciate your prompt response to send us through the forums looking to see if there was an answer to my question. But unfortunately I must not have STFF very well because there is still not an answer to my question. I am asking how to program a smartkey for a w209(not w208) 2003 CLK500. Can I program it or must it be done by a dealer.

Searching (again) through the forums before I wrote this post did let me see something else that seemed like a nice addition. One of the posts shows someone with a W208 ordered the new chrome key. Has anyone tried this for a W209 and got it to work?

 

rparrish22,

To be honest with you IDK how to make it work but I was just got it from a dealer for $200 even

 

honestly, they are only good for parts, they can never be reprogrammed by conventional means, i have a factory mercedes diagnostic system and am still unable to, i am sure the department at mercedes that makes them could, but i am also sure they would rather sell you a new one, unless your key is phsically damaged externally dont waste your money, they can be opened and the internals changed to another good housing

 

think its possible to take a new key apart and put the old key inside of it?



maybe?




ALi

 

if i remember correctly, you cant do it yourself. you have two options. get a new key from the dealership or get it from oemparts. they somehow program it if you give them your VIN . (if you search chrome key, you should find some posts)

 

No the dimensions are different.

 

it is possible, the only variable is the donor has to be physically the same type key

 

all i can say is, i think u need to take it too a dealer to get programmed.
