hi im new to this website, and looking for someone to help me with my car, i bought my swift not too long ago and it is all standard with no modifactions. the car was only supplied with one key, i understand there are 2 diffrent types of key mine is the lower spec key with the 2 buttons on it and it does not split apart as i understand that style is for keyless entry or stop/start functions. anyway the key was lost and i wasnt paying the fortune that suzuki dealers wanted as well as getting the car transported to them so i found and identical swift at a breakers yard and aquired a new ignition barrel, door lock, immobiliser ring, and the fuse box/immobiliser unit which is located on the far right underneath the dash board, after removing the door to gain entry to my car i proceeded to replace all my old usless locks with my near gear, now it is all fitted the immobilser warning light doesnt come on when i try to start it, i programmed the key to the car so the buttons on the fob work the central locking and i know the transponder in the key is being read by the ring as it does not activate the imobilser warning light. however the car turns over but does not fire. also i have noticed that when i turn the ignition on the battery warning light flashes as does the red airbag warning light (i assume the pattern of these flashing lights is an indication for an error code??) do i need to replace the engine ecu with the one from my donor car? (i am unsure if the immobiliser is also programmed into that ecu unit), i left the battery disconnected for a while (when i was fitting all the new parts which i assume would of reset the immobilser) apart from that i am really stuck do you know what i could try or anyone that i could speak to over the phone to help get my car going again. many thanks connor.
