In 1996 Mercedes began locking the ECUs to the car that they came in. As some of these cars get older, it's becoming difficult to justify spending the money for a new or re-manufactured ECU. We are able to unlock the ECU and put it into a "ready-to-program" state, just as if it were a new unit. Once the unit is unlocked, you can install it into your vehicle and use a factory tool or equivalent coding solution. At this time we are able to unlock the following units:

  • HFM (104/111) - $250
  • ME 1.0 (119/120) - $250
  • ME 2.0/2.1 (104/111/112/113/119) - $250
  • ME 2.7/2.8 (112/113/137) - $250
  • ME 9.7 (272/273) - $300
  • SIMM4 (271) - $300
  • CDI (642/647/648) - $300
     

NOTE: Siemens manufactured ECU's with part numbers beginning with 111 cannot be unlocked at this time


Is it safe to go with an unlocked unit?
Generally speaking, yes. Most used units are coming out of wrecked vehicles and if they were stored properly will be perfectly functional. We would advise avoiding flood damaged vehicles as a source for parts as water corrosion may not be visible from the outside of the unit. Please keep in mind that while the cost is cheaper, the risk is higher with used parts. There is no way to guarantee the longevity of a used part. 

Do you provide the used unit?
No, you will need to source the used unit. We are happy to provide the contact information of some reputable salvage yards that we know. 

Will you test the unit for me?
We will only do a basic check for water or electrical damage as well as check for communication with the module to verify that it has been unlocked. 

What's the warranty on an unlocked ECU?
Other than verify that the unit has been unlocked, we do not offer any warranty or guarantee on used units that have been unlocked. 

How long does this service take?
We can typically perform this service within 1-2 business days of arrival. Including a note with your contact information and what service you need done will help expedite this process.
