Thanks all in advance for any replies, first, do you only get about six warnings to change
remote battery?...

My MY24 Jazz (bought 08/2023) has just thrown the key fob low battery warning as well.

From my experience: You get these warnings every bl**dy time you turn the car on again!
(I only wish they would cease appearing after six times)

The repeated warnings are so obnoxious that I chose to replace the key fob battery the very same day!
Which, by the way, is quite easily done - just use a good lever - I used the emergency key)

Yes I only had about six warnings, sometimes when car was started and sometimes every
2 or 3 hours, I changed the battery 3 or 4 days after the warnings had stopped following
the advice and instructions of Mr Lord Voltermore, I liked the post from dfconnolly about
holding the two buttons down on remote till light flashes which disables the signal brought
a faraday bag for no reason now as I see it, I suppose I could still use it as a new battery
every two half years is nothing.

My strategy was to use 1 key for a year, then change its battery and use the other key for the next year and so on

Never had any key battery warning and just changing one key battery just a safety for me that if something goes wrong I still have the other key

You can still get into the car using the physical key (which can be released from the fob) with a dead battery. Then the car can be started by holding the fob right next to the Start button.

Mrs LV and I dont have 'his and hers ' keys .Whoever uses the car uses the same 'master' key.  The 'spare' is left at home  if the  journey is only local.    I do switch the spare off by the double button method but on at least one occasion  it was found to be on and active when brought near the car.Probably due to an inadvertent button press when handling  ,maybe months ago, or only the  last  few minutes.   It  once caused some consternation  not long before I had a non refundable channel crossing booking. .The  car bleeped at me and refused to lock. Eventually traced to the spare key being active and packed in luggage in the car      A daft place . When on it uses battery and vulnerable to relay attack. Even if its off  being locked in the car is not an  ideal place if you lose the master key.  At least the bleeping was a salutary lesson we would not have had if it it had been off or shielded by a faraday bag.
  I also keep a CR2035 battery in the  car but have never needed to use it. And I now keep both keys hidden away in farday boxes  at home , even if I know/think  its off.

Good thinking that is, I can't do it that way because when we are out together [wife]
we always get spilt up and never know who will get back to car first.

Its amazing how slight differences in lifestyle  can change our perception and enthusiasm or dissatisfaction with various aspects of the same car.
  We live within walking distance of the  town centre and several supermarkets and rarely use the car for this purpose.  Mrs LV walks twice a week to the supermarket  for complicated stuff needing culinary skills and planning. On other days I will walk to buy milk and other heavy basics. She has said she would hate to have me hanging around as a 'trolley minder'  getting in every ones way.  For other shops ,interests, appointments  etc that would bore the other we usually go alone.  As we seldom do short journeys  the car rarely gets problems with flat battery, splitting seats etc .    On the other hand we clock up a lot of miles together on long trips, so I have more appreciation of various driver aids such as ACC.

Don't you take the Honda 50 and the trailer?

Nah . Thats at Angkor Wat, Cambodia.  Not very convenient for going to Waitrose. But if (or should that be when) we have to give up the car   some of these new electric cargo bikes/trikes  might be worth consideration.
