It's just frustrating tbh and at the moment just going to have to spend £14 a fortnight on new key fob batteries because they're inept and wont/don't listen to what the problems are. 

I recently replaced my key battery with a Duracell and it didn't work initially. I refitted the battery and decided to check all the battery connections in the fob, one was twisted out of place so straightened that out and checked all other connections, reassembled and everything was fine. Clumsy battery swaps caused a problem but it is an easy fix.

Just another quick update on this tedious, long running saga. Trudtford had the car for a week. They said they've found the issue, it was the car battery. I had my reservation but agreed to changing that for a new one. It's lasted a week window won't close again and now it comes up with the key fob battery warning again. Guess where I'm going at 8AM...for the 4th time.

It's a BCM or RKE fault I think is the cause. The key fobs are fine. The batteries are fine. This pile of sh*t as been in the garage more than it been on my driveway and they still won't fix it. It was in for a week last time, supposedly to check all that. After replacing the car battery I asked if everything else was checked and they said yeh. It wasn't. On the invoice. Work carried out - new battery fitted. Nothing else.

I take it it's still in warranty?

Contact Ford CRC and tell them about the issues, they will, at first, tell you to take the car to a different dealer. Ask them for a Ford engineer to come and diagnose the fault, if that doesn't fix it, reject the car

Yeah, they don't do anything unless they are being paid. They just guess.

Contacting Ford CRC should help getting it thoroughly investigated

Would you believe it...it's just out of warranty. By 3 days. Might just take it to a ***** backstreet garage and them have a look at it. Can't be any worse than who I'm dealing with now...

If the fault occurred and was known about by the garage before the warranty expired it is still covered.

Absolutely 

With another thread on MHEV issues running at present:

I wonder if there's some common factor with MHEVs? Certainly doesn't sound like the "routine" Fiesta Mk 8 low charge issues we've become familiar with in the last few years.
