I have a similar problem now as well. I put the key in and all seems normal but won't crank engine. Tow truck driver came to tow the and putt on panic, unlock and lock buttons and somehow it enabled him to get the engine to start. He said he Thornton he "reset" the electronics by doing what he did. We have now taken the car out and are having the same problem but can't repeat what the tow truck guy was able to do. Nothing works. I hate to say it but its one problem after another with this car. Too many high tech features to break and, unfortuantley, too few competent mechanic's to fix them when they break. Even at the MB dealership. I won't be buying another one...worst car I've ever owned.

You do not seem to be a DIY type of guy, therefore if I were you find a local indy with good MB diagnostic equipment. If he has the appropriate diagnostic equipment he will find your problem quickly. If not then my guess is just as good as-----

Additionally you have lost me----key won't move positions, however tow hack pushed the key panic button and then key would move and able to start.

You take the car out same issue occurs can't turn key or move shifter, however when you try tow hach panic button trick----nada----I am now left to believe the car is somewhere on the side of the road or did the car get towed. My guesses are as follows:

Does the battery have at least 11 volts?

When was the last time you looked at shifter bushing?

Did someone know if and where those coils could be bought?

BachelorDays

I broke into an old key I had from an earlier car and got the coil that way. I suppose one could buy a used key off ebay.

Not aware of these being sold on their own (but an electrics repair shop might advise with more certainty)..

Jacek123

Yeah i have done this allready one time, but i just wanted to know if its possible to buy this part separately.. i found websites like this:
https://www.distrelec.de/rfid-transp...4408af-112j-04
or
http://www.grupopremo.com/in/technol...inductors.html

But i dont know which coil i would have to buy, becuase i dont know how many Ohm, KhZ and so one the right own should have. its about 11mm long and i have found allready some of them..

BachelorDays

I don't have a spec for it.

My 2008 C300 Just left on a wrecker being towed to the dealership. My key unlocks the car, I stick the key in the ignition (hear the beeps) go to turn the key and a message displays saying "take the key out of the ignition". The car wont start. Key turns over but nothing happens except message. Radio works, windows work, car alarm works, door locks work but car won't start. My steering wheel was not locked. I read all the messages below page after page trying to see what might be the problem. Even my spare key does the same thing. When I get the "diagnosis" from the dealership and what was done to repair this I will post. Anxiously awaiting that call.

The same thing happened to me 2 weeks ago. I took my car to the dealership and they said it was fine, ran the diagnostics and everything was fine. Now it literally just happened again I dont understand what the problem is. same exact thing car wont start. everything works but car wont start and i keep getting that annoying msg. Anyone else have any ideas? should i take it to the dealership again?

I just thought I would let you know that I now have another intermittent fault on the ignition not the wipers etc this time.
When I turn the ignition on some times I get nothing at all turn it off on then on again every thing fires up you drive around for a couple of days fine then it rears its ugly head again switch off and on again sometime nothing then all of a sudden it fires up had the switch out took me 10 minutes to remove the ignition and switch now that I know how to remove it. Gave it a clean still the same, anyone out there got any suggestions on what it could be.

It’s a 1996 E320 WDB2100055 2A 195110,http://www.benzworld.org/forums/w210...gnition-6.html


part on the switch is 2105450604 and has only 8 pins will the
W0133-1608536 switch be suitable which has 16 pins!

Plutoe

Wow did they give you the runaround at kiddybenz----I have no idea what you want. All I can say is that with the VIN you provided the applicable ignition switch is 129 545 02 04. The number you gave of 210 545 06 04 does not exist in EPC.

The WO part number you referenced must be a non OEM for which I can't cross reference and once again totally different that 129 545 02 04.

Instead of all the previous gross misinformation and HS -----just what is the problem!!

skyrocket2

that is the part No writen on the switch it has a green back plate so it must have existed at some time there a couple on ebay, not convinced its the switch looks more likly to be ths Daz

Ok so I know this is an old thread, but there's no other help anywhere on this subject. My 2011 C350 just started this phenomenon.

Car unlocks/locks; panic works; start button doesn't work; insert key, tilt moves, dash lights up, radio works; turn to position 2 and no crank. Battery is fully charged.

I tried everything in this post that I could while I was at the YMCA with my kids, nothing. I even went across the street and bought a brand new battery, same issue. I even tried the re-sync procedure, no joy. My wife shows up with her key and same issue. So this is not a key issue, this has to do with the ignition switch.

Seeing that this thread is so old, hasn't anyone figured out what the root cause problem is? Dealer is closed, so I'll have the car towed in the morning...

raymond g-

well, since your car isn't a w210, there is a likelihood that your problem isn't
related to anything as old as our cars

MajikTom

Well since this issue was very similar to that described in most of the posts herein, I thought it would be related... I'll start a new thread in the C section.

the ignition interlock, the starting system has undergone some degree of
evolution the past 10 yrs so though the symptoms may sound similar, the
fix may be quite different. but yeah, having your post in the same forum
as you car's siblings will probably garner more apropos replies.

I had the problem of an intermittent "key not recognized" problem. My car would start by placing the key in the ignition switch. The fix: I took the key apart and placed a small piece of scotch tap on the back side of the battery. This allowed the batter to make a better connection. This seems to have fixed the problem for me. I hope the fix is permanent and your solution is just as easy.

This would not help with a w210 since the batteries are not used to start the car, only to lock/unlock.

Well I finally fixed my ignition problem I fitted a new ignition switch after prating around with the old one for 6 months or more ,£80 for the switch.

Hey MagicTom - I have just started to experience the same problem on my 2012 SLK AMG. It is still under warranty, but because it is an intermittent fault, the dealer says there is nothing he can do unless the onbaord computer registers a fault. It even happened while I was at the dealership, but by the time he hooked up the diagnostic m/c the car started okay. He says Mercedes are aware of the problem but aren't doing anything about it, because it is happening to too few cars.
He thinks it is a fault with the anti-theft module, but neither he nor I want to go to the expense of trial and error. What a bummer!!!! The car is going straight onto the 2nd hand market. And Mercedes can stick all the rest of their cars up their proverbial.

I have a c300, 2010. The car would start only if I do not remove the key from the ignition. I took the car to the mechanic because they car was completely dead and had unlock the wheels, and everything else.... they told me it was they key, they order the key and it wasn't the key...Then I was told it was the ignition, I decided to pick up my car. When the tow truck is getting ready to pull the car, I put they key on the ignition and the car started with no problem, so I drove the car home...I notice that as long I do not remove the key from the ignition the car will start but if I remove the key and then try to start it again, the car won't start.....Have any idea what is going on with my car? Thanks...

Wrong forum.

I had to replace batteries in my fob (W211) because the remote lock/unlock stopped working. I opened it up to get the battery part numbers. The next morning I started the car and made a stop. The ignition would not turn. I waited a while (few minutes) and tried it again. It did work.

Now it will only turn if I press insert the fob and then press the lock button.

Couple of notes:
I did replace the case a few months ago with a non-MB shell.... not an issue... tried the original shell.
The circuit board did fall out of the shell when I checked for the part numbers... So, it could have been damaged.

I likely damaged the coil (described in earlier posts). I am fortunate that I didn't do worse damage.

For now, I will insert the fob and press the lock button before turning.
