Help with Key Sync with Alarm

[ely]

Right, a couple of months ago my 172 cup decided not to start. I had my mechanic look at it and he said it was a problem with the key sync with the alarm/immobilser. He put a new battery in the key fob and has been fine till this weekend and it has done the same thing. I turns over but will not start, it sounds like the immobilser kicks in. He said its an intermitant fault and he doesnt know the cause and said take it to a main dealer, but i dont wont them to rip me off so i thought i'd see if you lot (basically the experts) knew what it was and how to fix it?

Regards

I had this problem recently when I unlocked the car, opened the door but didn't put the key in the ignition and left the door half open.

Are you unlocking it, getting in and starting straight away?

mine seemed to be okay since i solved the back light problem becuase it was all mixed lol when i brake the indicators were coming on very lightly but i think that caused the problem?

i have no idea but mines been ok for 5 days now! Tick Tock Tick Tock just waitng for it to happen again. I read on here that someone got and autoelectrician out and they took out his immobiliser and that fixed it so i might have that done.

Fingers crossed for both our cars then!
