Hi, new to this and in need of help. I can see there's been quite a few posts on the key fob, immobiliser issue and it's all a bit confusing. I'll try and explain my issue quickly and as simple as I can.

I have a 54 plate cmax 1.6 diesel.

I have 1 fob key and 1 original key(with no fob or immobiliser)

Two weeks ago I thought the battery went. I replaced this and for only about 2 days it was working. Surely the battery should last longer than two days???

I didn't do the re programming thing cuz it just worked without doing it. Should I do it?

I don't want to go to ford cuz they'll just want my wallet empty, and I don't want to buy a new fob off eBay if it'll just do the same. Also I wondered if I could swap it for the flip key fob? Could this be possible?

Any ideas on what to do?

Thanks

Hi and welcome have you checked the connection on the battery

Yes, taken it apart and back together a few times. Someone's told me it could of been a crappy battery. It's not a decent one, some Japanese make. Do u think it could be that?

If it worked ok to start then just stoped it could be a faulty batt. Best thing is to try another batt if you buy a cheap 1 just to check its not the key fob.

I'll give that a try and keep u informed

Ok no probs cannot se the point on paying for a exspensive batt if the key fob is knackered
