If you are talking about the large black wire that connects to the EIS (ignition switch) that wire goes to the gear stick. As soon as you turn the ignition ON, it releases the gear stick so you can change gears.
@Proud Papa - Hi Greg. Yes it should work as long as the EIS is an FBS3 generation. After 2014 Mercedes changed their 3rd generation (FBS3) to fourth generation (FBS4) system. FBS4 systems, at the moment can be programmed by Mercedes only. I hope this helps.
@Proud Papa - Sorry Greg I just noticed your vehicle is a 2003 so it should be just fine. Tomorrow I will be cloning a w639 VITO VAN EIS and I will film that as well, so keep an eye.
So u just made him a new key fob. How did u know the ignition switch was bad.? I have the same issue my e500 I went to the gas station and remote was working fine . Mind you I dropped it 2x and the remote stopped working left me stranded and had my car towed back home. I've had same issue in the past where my remote got soaked in water and stopped working . Called a key reprogram and he made me a new key and it started right up.
*@Charlie Vega - I did not made him a new key fob. He's EIS (Electronic Ignition Switch) was faulty, so what I did was clone a new (used) EIS. I did not do the diagnosis on the EIS, a garage did that and they called me to clone a new one. As far as your key is concern, if you drop it in water what you should do is clean it with alcohol like ISOPROPANOL or similar. This is to get your remote back and working again. As far as the car not starting, while you dropped the key, the transponder must of been damaged or came lose from the board. In this case you need to open the key fob and inspect it. Be careful while opening not to lose anything that came lose because you might be able to solder it back to the board.*
@Charlie Vega Sorry for the late reply. I did not make a new key fob. The original key was working fine since we cloned the Ignition switch. In your case, your key was broken since you dropped it but that doesn't mean, you needed a new key. Maybe the coil was disconnected from the PCB board from the drop and all you had to do is solder it back. As far as soaking the key all you had to do is dry it as quickly as possible, then clean the PCB board with alcohol (Isopropanol alcohol or similar).
hellooooo, i got a question, the doors where unlocking/locking with the eis faulty? i have the same issue and i want to know if is the key or the eis :P
Please give me a clearer picture. The doors were locking/unlocking or ARE locking/unlocking????? Are the doors locking/unlocking by themselves or what??? I don't follow you!!!
@@yiannakosautomotivekeys2380 they dont lock/unlock with the key, i replaced the key battery (is my only key) and the battery og the car was disconected and now i want to know if is the key or the eis
@@ChillRighty Hi. Just seen your comment. If the ignition does not turn while on the car, there are two possible problems. 1. The key has lost it's data or gone wrong and 2. the ignition switch (EIS) has gone wrong.
I had problem with EIS, but once I took it out, took it apart, clean those electrical contacts and connectors, and put it back together, the problem went away. I do believe much of these problems arise from corrosion of electric contacts.
@David Jacob - Never thought of that actually. I always thought they go wrong mechanically (internally). I have a few EISs that I kept from customers. I will do the same and see of they come back to life. Thanks
Excellent job and video. Where can I purchase the Computor hardware you used to read the EPROM and Flash files from the original and donor? Did the donor switch come with a key or were you able to use original key. Thank you for any response! I’m Kevin
@Kevin Pinson When you clone the EIS the original keys will work. No need to program new key(s). The programmer is called "Xhorse VVDI Prog". You can search google. With regards to the adapters you can do all this without them, but you'll have to solder cables that come with the programmer to the EIS. The programmer has wiring diagrams as to where to solder and what colour cable. I hope this makes sense & helps.
If I sent you the original and a donor would swap the EPROM and the Flash files for me. I’ll be glad to pay you for what you need for the job. Thank you very much for any response and also the original response!
I have a 2008 211 E350 w the exact problem as yours. Would it be possible to send my original and donor and you program the donor w info from original. Let me know if you can do this for me. Thank you for any response!

@@yiannakosautomotivekeys2380 I had the same question they stole my brother eis out of the car ( very odd) and only the eis how can I get the eis information so I can put it into a donor eis
@@juanrendon3639 Hi. You need to get the information from the Engine ECU. From there you can generate EIS file. You will also need the SSID which you can get from any of the keys assuming that you do have a key.
