Have been staying with my parents over Christmas, having packed the car up and about to leave to drive home I try to start the car, the engine turns over then dies as if not enough power in battery, (cold day, doors and boot open for about two hours which explains the low battery) Charge battery for an hour, engine just about turns over, but doesn’t start and then dies, after trying (unsuccessfully) to jump start I came to the conclusion that battery is dead. Remove old battery and then go get the new one which is fitted after twenty mins. Now the immobiliser has kicked in (constant flashing red light on clock) and engine won’t even turn over. Any ideas about how to get the car started again? Any help greatly appreciated, Ford dealer can’t see the car until after the bank holiday and I really need to getwife and two kids home (200 miles) before then.

Do you only have the one key? My remote fob sometimes worked and sometimes not. The spare standard key
started the car every time though.

I found putting the key in upside down worked better. Maybe coincidence though?

ECU is confused
Put key in the ingition and turn on. The pats light will flash fast (twice a second) for 1 min. When it goes solid (on), you can start the car.
Good luck.

Thanks for the advice guys. Unfortunately the first reply didnt work as my spare was at home 200 miles away and I didnt get a chance to try the second as I had the car towed to the dealers. Thanks for trying though, hopefully someone else may find the advice useful. Delaer told me the imobiliser needed reprogramming and that I needed an extra key to do so, £200 later and I was on my way. Expensive but at least I was home for NYE!

You should have called an auto locksmith, we charge about £140 to come out and supply 2 working keys.
