Corsa D It won't start - Wadoud - 03-05-2026
Hello, I have a 2007 Opel Corsa D. The immobilizer is triggering, and the engine codes P1632 (Wrong transponder key) and P1679 (Wrong environment identifier received BCM) are appearing. The ECM and BCM have been replaced, and a new key has been programmed, but the problem persists. Any ideas what it could be?

I performed the programming using орсом, in the programming function, I only saw the option to program the ECM and the BCM.

No, I didn't do that. Can it be done with ор-сом on that car?

орсом works well for it but all must be reset ecu,immo,bcm and ipc program ECU and immo together and then bcm last ipc and match keys job done

I've already done the programming several times and nothing, can the immobilizer be canceled?

On this car, sdm is also рдят of immo set.
But why all unnecesary рдят5 change, when this needed only bcm reset and program? It was due to low voltage. Known for at least 15 years.

They brought me the vehicle with the modules replaced, and I programmed the new key since I was unaware of this faul, I should have asked before doing anything.

try to get the original рдят5/modules from the customer if possible
