I can just imagine how tiresome this would be for you, admittedly, it's an awful hassle twisting that bit of metal to fire the engine into life rather than pressing a button 🤣

It's not the physical issue of twisting or pushing a knob, but the problem with remembering which pocket or  bag my keys are in 🤣

This thread is taking a serious wrong turn {euphamisms] pushing things into holes, pockets ....... didnt know about the twisting bit, is that where ive been going wrong all these years ??????

And having to switch the lights and wipers on manually 😱

I asked the wife, she doesn’t know either.

Message just came up in my dash, so will be changing the battery when I get around to getting one.  How long do I have after the message first comes up?  

I think my message was on for several weeks before I changed mine. Don't panic.

BUT don't forget to change spare fob too, as that will have been transmitting for the same amount of time as the one you've been using, even though it's been put away in your bedside drawer since new!

Good point. I got the message on the way back from my first MOT - I was using my spare as I always do when leaving my car for service etc, as my main fob has my house keys on it. Changed the battery in the spare and the other one went a few days later.

Well I never knew that they had made the Mk2 Focus with a starting handle 🤣

The handle is fine, it's the kickback that's the killer! LOL

You need to get one of these, put you car keys on it, and you can separate them out instantly for car servicing and take house keys with you...

Only if the car is pre-2020.  Any newer cars with sleepy fobs only transmit when they're being moved which should make the batteries last longer...

Lol I'm surprised at you Stephen. That costs £1.99 whereas I can slip the spare keys in my pocket for free!😀

I assumed that, but mine is 2019 build.  I am using the spare until I get around to getting batteries and no low battery message yet, then I'll do the two together.

My point exactly LOL I have no issue at all having to put my key in the ignition, and twisting. I rented a car last year with 'keyless', I absolutely hated it...

I can just imagine you warming your hands at the camp fire in your cave - "that central heating idea is idiotic, what's wrong with chopping down your own trees to create heat, it'll never catch on?  as for electricity, forget it⚡"
