PCM flash is required or not

I am having a jeep 97 5.2L and the PC got fried

managed to get another PCM with slight different Partnumber. Now the jeep starts and off immediately.

I suspect that the PCM need to flash with correct VIN and model.

The PCM you got has a key code in it and its not detecting the correct key, so it starts then shuts off.
Around $200 at Dealer to get a new key cut, or go where you got the PCM and ask them for the key and the ignition switch out of the ZJ the PCM came from.

Thanks foe the replay,
actually my jeep (export) is not equipped with immobilizer. also the Dealer is not supporting old vehicles.
IS it possible to disable the immobilizer on the PCM or can i re-flash the PCM to the correct P/N
original P/N is 56041418 and the replaced PCM P/N is 56041410 (California models).

In this art getting skilled technicians are difficult. Thanks in advance
