Can't program new transponder to PCM
Lost my keys and transponder fob for my 1997 ZG Jeep Grand Cherokee Limited 4.0L..... have bought new transponder and keys, keys fit and work all locks manually but using the correct DRBIII Scantool the local Jeep dealer can't program my PCM to accept new signal. He says that power at OBD2 connector under dash cuts off power before he can go through the programming steps.
So, no de-immobilisation or locking/unlocking......
I'm stuck in Broome, W.A. .....any help appreciated
