l have a 94 el falcon and are having heaps of trouble with the smart lock. When i drive for 5 to 10 klms, the smartlock dash light flashes and the hazards come on. The only way l can stop it id to turn car off and press the door button on the remote. Have tried new remote, have relearnt the bem and pcu, repaired all trouble codes, although still have a 844 which is 'car immobilised by smartlock' . Have cleaned and replaced interior light and relearned bem again. This has really got me stumped. PLEASE HELP!!!
