Used Electronic Ignition Switches

Used Genuine Mercedes-Benz Electronic Ignition Switch (EIS). We have many EISs in stock and ready to ship. We can ship them unprogrammed, locked, virginized, or cloned. With cloning, you’ll need to send in your original EIS and key fob. If it is not available, you’ll have to send in another module that is part of the DAS system. For example, you can send in your ECM instead of your EIS.

Wife’s C300 stranded her in the Costco gas station, the car suddenly failed to start! After much testing & trouble shooting I fortunately  found this place!!! The ESL failed and Michael absolutely has the fix. Not only with the video’s but when you call, you get a call back! I took out the Ignition and sent it and the key and just as promised, I got them and the Emulator back, put it all in and it’s never going to happen to her again! I only gave it 5 Stars because I couldn’t do 6!

There has only been a few times I received service as excellent as this. I was able to identify the issue I was having with my Mercedes from his YouTube step by step instructions. Once I contacted him the response was immediate and informative. I mailed the part from P.A. to C.A. on Sunday and received back on Wednesday morning. As soon as I plugged it in and turned the key my car started. Through Micheals instructions he was able to help me from making a simple mistake of my steering column locking up and that would have cost thousands. Its a fantastic and great service and I am so appreciative. This was a E S L reprogram on a 2008 Mercedes C3000

This is a great shop. Run by actual people. Many sites do not list a physical address or give you any confidence that you are going to get a solution to your aging Mercedes. All problems fixed and helped through the process. Thanks MBS!

If you are looking for the best service on repairing your ECU, these are the people for you !!! Call them from Florida on Friday morning. Mailed off my ECU Wednesday night to California. And received it back on Friday morning, fully reprogrammed and repaired.

I have a 2010 ML350 that was having an intermittent starting issue. I took out the EIS (Electronic Ignition Switch) and sent it to them. I know that these issues can be expensive but they did it for a much better reasonable price. They tried a basic fix but the unit was too broken. Once I received the cloned replacement, the engine started right up but I got an anti theft lockout on the radio. I messaged them and they told me it was an issue that happens on some ML's. They paid for shipping and I quickly sent it back out. The same day they received it, a new replacement was shipped out. Within the week, I received the replacement. Just installed it and now the car is starting with no more anti theft warnings and the electronic trunk hatch is working once again! (It was not operating when the EIS was out). Was so satisfying to get it working for such a reasonable price. These guys are blessed with talent and were able to do wonders for my 2010 ML!

The service that Michael provides is so valuable. I was quoted 3500 to fix my EI/ESL and was able to fix it myself with Michaels instructions and parts for around 900 including shipping. It only took a few days to get the parts back!  My Mercedes would still be sitting if this service want available. Thank you Michael!
