Greeting. The EIS on my vehicle will no longer turn at all for whatever reason. Anyone out there who may be able to guide me as to how to repair it or if it may be possible to bypass/disable the Drive Authorization System altogether and if so, how would one go about doing that? Its a 2005 S500 (Base). I understand that doing this comes with risks, which I would be willing to live with. Thank you all in advance.

Have you checked the fuse that's in the dashboard? It's where the passengers side door meets the dash Its a 7.5 amp fuse. I didnt have a 7.5 so i replaced it with either the 15 or a 10, i cant remember. I forgot ehich fuse it is but there are only 9 fuses. Wont take long to check them all
I had the same thing happen to me. I almost sent my eis out for repairs. Took me weeks to find out it was just a fuse in a hidden fuse box. Hope this helps
I had an issue on my 2004 S500 where the key would not turn in the EIS when it was below a certain temp and the start button did not respond.
I ended up taking it to some idiot who was Mercedes accredited to repair it. They diagnosed a faulty EIS and said they would get a second hand one, clone it and code it to my car. They stuffed this up so badly that they added 250 000 miles extra onto my odometer, damaged the SRS coding and cracked the outer case of my instrument cluster when they tried to remove it in an attempt to re-code it.
No one was able to resolve this for me and I have been to about 8 different garages...all claiming to be Mercedes experts. Mercedes are happy to help, offering to charge me $4200 for a new EIS, new key, new instrument cluster and their labour.
If you love your car and it is a faulty EIS module, just go to the dealer and pay the $1000 for a brand new one that will last another 20 years...I deeply, DEEPLY regret not doing this on my car
PS: You cannot bypass the EIS/Drive Authorization System. It is composed of 4 different things that talk to each other (EIS, Key, Engine ECU and Gearbox ECU)
You can also buy a matched set of those 4 parts on eBay for about $350 and swap them over
100% correct but you just have to be careful of the mileage on the EIS that you buy.
The facelift W220 stores the mileage in the instrument cluster and the EIS. If the OPs car has 100 000 miles on the instrument cluster and the EIS he buys online has 200 000 miles on it, this will overwrite the cluster and the car will now have a permanent 200 000 miles on it .
There are apparently "gurus" out there that are able to hack the EIS by breaking the security on it, then copy across all the programming etc...but this requires de soldering the chip off the EIS which is very risky (I have yet to find one of these people...in South Africa anyway)...
Who cares about what mileage is displayed ? These cars are worthless
Maybe in your part of the world...where I live, an average example can go for $4500 and a excellent, low mileage one can go for $7000 to $8000!
Bear in mind just because one sees something as worthless, does not mean everyone else does
You still don’t get it , if you just need your car fixed to run , then you buy the 4 parts , you don’t care about what it says on the screen as long as it’s running again
the resale value doesn’t matter on a car you are driving .i haven’t seen anyone talk about resale value on a w220 in years because they are all worthless besides the s65 amg and the w220 is one of the cheapest used Mercedes you can buy.
even the v12 s600 are under $8000. Plus the difference between $4000 and $7500 is nothing those are both cheap used cars , and If that means something to you then you are broke and should be finding the cheapest way to get the car running.
Plus even if you are concerned about resale value on a w220 (what a joke ) any buyer would see from the service records that you car jumped from 100,000 miles to 300,000 miles and would see from the receipts it’s due to a parts swap
. These cars cost less than a used Hyundai .The fact is nobody is taking their w220 for dealer service any more and most dealerships will not even work on these cars, specifically because they are worthless and the owners of a cheap w220 car cannot handle the 4 figure repair bills typical of Mercedes dealers, so they either decline the repairs or abandon the car at the dealership , never paying the bill

Thanks man, guess you really put me in my place
OP, to sum up...you cannot bypass the EIS or Drive Authorization System...its an integral system.
If you don't care about your car, get the 4 components that were listed above, have someone code it to your car and take your chances.
If you care about your car and value it, which clearly seems rare these days, then take it to Mercedes and have a new EIS fitted.
Your summary is even wrong - if you swap the 4 parts taken from a Single donor car , no coding or programming is needed . You just swap the parts and your car is fixed

Are you sure it's not a fuse? Are you 100% certain the 7.5amp fuse isn't blown? I had the exact same problem. I even pulled the fuses on the passenger side floor board. Eventually I stumbled upon a video from taiwan and it showed this hidden fuse box. I was like wtf, why did mercedes hide fuses behind the passenger side door. I would have never found it if not for that video.
You know, a funny thing about my eis. When I tried to learn how to reprogram keys for my s600, I accidentally deleted the vin inside my eis. Car still operates just fine. The missing vin triggered the srs light and that's it. I have no clue how I deleted it. I bought a cgdi mercedes key programmer and the English in the thing was terrible. It took me two weeks to figure out you had to pull a password off of the eis in order to program anything. In the end I was only able to program a key that could start the car and nothing else. What use is a key that can start the car but can't get in the car? I've thought about buying the autel key programmer but that thing is like 4k-4.5k. A little too expensive if your only working on one car. I have the autel ms906ts. I wish I had bought the $4000 unit instead. The main difference between a 2k unit and a 4k unit is the ability to write the vin to control modules. I wish I had know that when I made my purchase, but yeah, check the fuse behind the passenger side door again.

Actually not...I know you don't care about your car but you will actually need to code it to for the SRS system otherwise your airbags + Pre-Safe wont work and you get a nasty red SRS alert in the centre of the dashboard. This is because the components need to be VIN coded. I have been through this so I know its the case.
Before you feel the need to correct me again, understand that there are people that care about things working perfectly on their car, that don't want weird lights and non functioning systems. If you don't, good for you, if the OP does not, good for him...but I am just providing the information to do the job correctly!

You're absolutely right about the srs. I've gone to mercedes to see if they could put the vin back into my eis with no luck. I need that autel unit to rewrite my vin into my eis. For now I just gotta deal with the eis light on my dash

Unfortunately, as tusabes pointed out above, Mercedes have very little interest in helping people or going "above and beyond" for their customers (and this is not just an issue with people running older models). Have you tried looking for a local garage that has a Mercedes STAR\DAS or an Autel system who can code the VIN for you on the EIS (must be a lot cheaper than buying the whole Autel unit )
Well I drive a 05 s500 w220.175 7 speed trans which am currently trying to figure out right now
