if you "disabled the immobiliser" with EKA you are a genius... though after reading your statement i'm affraid you're not(sorry)... the EKA will remobilise the car once if the fob fails just untill the ignition is switched off that's all(that's why EKA = Emergency Key Access code)... it doesnt "disable" anything, you have to use it again and again untill you disable the immobiliser(alarm) completely with tester or fix the fob-receiver communication... unless the passive immobiliser wasn't disabled previously with tester
