We at Keymax Locksmith technicians are able to offer an immobilizer and ECU reprogramming service. If you have a customer who has lost keys for a Toyota, Lexus, Honda,(red key system) BMW, system 1 Volkswagen, Audi, certain Mitsubishi, and certain Hyundai vehicles, we are able to either Reprogram it back to factory original condition, (automatic registration mode) add a key directly to the ECU or extract the security code needed to program the keys with the use of a diagnostic scan tool. In certain vehicles we are also able re-link an immobilizer ECU back with it’s main engine ECU to save the cost of having to purchase a new immobilizer and engine ECU set from the dealer.
