Mercedes ignition switch EIS module easy repair. Fixes no start, intermittent key switch condition.
Simple and to the point video showing how to do an easy repair of a Mercedes ignition switch. The Mercedes EIS (electronic ignition switch) module is well known to fail, causing no start, no crank, and even no accessory or no power conditions when turning the key.
This video shows how simple it is to repair yourself, in a matter of minutes, what would cost hundreds of dollars to repair at a dealer.
The Mercedes ignition switches fail because of broken solder joints on a small 3-pin connector inside of the switch module. It's very easy to remove from the dash, and very easy to disassemble the switch to get to the connector and resolder it.
In this video, I quickly and succinctly show you how to do everything you need to do to make your Mercedes key switch start like it's brand new again.

It worked! Mine had been intermittently failing for a few months, but never actually left me stranded. Figured it was just a matter of time, and would be an expensive dealer item for the fix, so was getting ready to bite the bullet when I stumbled across your vid. Verified it with a couple of other vids, followed your instructions ... and peace of mind has returned. Many thanks for posting this!
Didt u just saved me trip to dealer and possibly saved me thousands of dollars, my car been sitting like that for more than a year, till i ran in to your video, followed your video and fired up :)))) Thanks for your time and your video. Nice to have my car back after a year :)))
I think you just solved my problem, ty.
Thank you so much
Thanks!
My R350 push button start stopped working and the mechanic said a module needs to be replaced. Is this the module they’re likely talking about? Thanks for the video
Curious how you determined where to start to remove the panels? I would have started pulling and broke something. Thanks
would this work on a c300..?
What if the key turns and starts it but then car shutoffs 2secs later , it’s Giving me DAS & eis codes on scanner
Thanks for the video well done. Would this piece have anything to do with intermittent AC loss of cooling? Sometimes it blows cold sometimes its warm. Just curious. Thanks

I wouldn't think it would affect the AC. Perhaps a faulty clutch on the compressor, or low freon so the compressor kicks out on a low pressure condition.

@PrairieCordgrass thank you. I attempted to solder the pins today unfortunately I couldn't get it to work. I assume the solder must not touch the other pins on that board? After trying a few times I pretty much ruined the little pin plug in. 😕 rookie!
When I insert the key, it does not turn, and the fan turns on automatically. Mercedes w220 s500
Hey Is There A Video On How You Removed The Stereo/Climate Control Unit In Order To Access The Eis?

There probably is, but I didn't make one because as I recall it was surprisingly straightforward and easy to take those out.
So this is only if the key turns and nothing happens, not for a key that won't turn right?

Yes, This fixes the problem where the key turns but no electrical connection (no engine cranking) is made.

If you just got the key programmed, and it never started the car, I would think it's probably bad programming of the key.

I'm worn out with it all..Learning alot this evening .. ESL and DAS look like I need to pull out and get re programmed? Gonna try and hit the ESL unit with a hammer to see if it frees it up in the morning.. Great video by the way ..
When i put my key it always turns but when i put it 2 position 1 sometimes its like the car is dead and the lights wont come on and when i try and start the engine nothing happens. Is this the same symptoms your car was having?

I am having issues with my Mercedes going from drive to park from 0 to 3mph slow speed, and based on my research at the Mercedes forums the culprit is the EIS module. Are you aware of this symptoms as well? They are saying it can also be a defective Diode. Any ways I would like to hear from you before I remove mine. Thanks in advance

No, I'm not aware of that symptom, but then I was only working on mine for the intermittent/no start problem. If the problem you're having is caused by a diode on the EIS, it should be pretty easy to remove, test, and replace if needed.
My steering wheel won’t lock when car is off is this also a symptom?

Also, the lights come on but no start.
Apologies if this question is already in the comments Will I need to do any reprogramming once I remove the switch My understanding is you do when you replace it I’m hoping you don’t
