Used / New ECU Programming:
Engine computers and other control units are locked once programmed and the dealer cannot program them to another car. We have solutions for most models, saving you hundreds over buying a new module.
Have you bought new parts and the dealer still cannot make the car run? We can help
Did you buy a lock kit 05101014AA (5101014AA) with SKREEM, Keys, and locks or a 05099541AA / A1708201826 (1708201826) SKREEM but dealer tools cannot make it work? Contact us.
Lock Repair:
Mercedes locks (as used in the Crossfire), especially the ignition lock, are prone to wear and damage. We stock replacement parts and keys and can often repair the original lock. Does your key turn just a little and then not turn on? Is the key stuck in the lock?
Used parts available
We have a large inventory of good used ECU's for
most makes.
FAQ's and tips
Wiring checks:
A1 = B+
A2 = B+
A5 = ground
B1 = ground
B2 = B+
F1 = ground
At crank:
A1 = B+
A2 = ground
A5 = ground
B1 = B+
B2 = B+
F1 = B+
If A2 goes to ground at crank and F1 does not go to B+, then there is a problem in the RCM. It can often be repaired.
If A2 goes to ground at crank and F1 goes to B+ then the problem is after the relay module. Either wiring or starter motor.
I cannot license my car because of a VIN mismatch. Why?
If you live in a metro area with environmental quality or DEQ inspections to license your vehicle, the VIN number in the engine computer must match your actual VIN. In some areas this may only apply to 2004 and newer vehicles. If you have failed to pass a VIN inspection, contact us.
Why did the dealer tell me I cannot install a used part?
Often this is true for the dealership and the equipment they are provided. The manufacturers want to sell new parts. So, they often "lock" an ECU once it is programmed to one vehicle. When the dealer tries to program it to another vehicle, their equipment will not allow it. Our specialty is "unlocking" these modules so they can be programmed again. Or, better yet, we can often program them in-house so they are ready to go when you install them. No trip to the dealer for programming will be necessary.
