Many control units must be completely replaced, due to the type of failure they have experienced.and yet other ECMs, ECUs are almost always in repairable condition. We charge $35. for inspection & return of your part (but only if there is no sale or repair,)   - Factory security - Anti Theft Systems -  Most all vehicles after 1998 have an anti theft immobilizer security system in place that communicates with the ECM, ECU and with your key. Reprogramming the immobilizer, ECM & key together is normally required after installation when an ECM, ECU is being replaced.  However we can usually help you by transfering the anti theft data from your original ECU over to a rebuilt replacement ECM, at that point, there is no reprogramming needed. ========================================== We charge $35. for inspection plus return shipping cost (but only if there is no sale or repair,)
