Help please,
I am away from home at my son’s wedding and just got key low battery warning.
I had a new battery available so decided to change it, but ever since I am getting key not recognising message.

I luckily have the spare key with me, but , it has not been used for quite a while and , you can guess... key low battery warning.
I can’t risk changing the battery in the second key at least until I get home.
How long do they last with low battery warning .? Just keeping fingers crossed.

Any ideas for me to try and fix No1 key?
I will get a new battery as soon as possible but the one I fitted was new and still sealed.

bad news Mike...

i can only suggest that you leave the FF for half hour or so and see if that message still comes up..

Hi Mike, if you have your IID tool with you , you could try re coding the key, it only takes 2 mins. Congrats to your son  2015 4.4 AB

My apologies if this is slightly off-topic but when you change the battery in one of the remote key fobs, do you have to re-sync the keys so that you maintain the driver personalization settings that are designated to that key number?

I don’t know what key you have but I’ve read about people changing keys and dropping the little black but that links to the car, sounds like it looks like a small piece of plastic but it’s inportant. Someone with more knowledge than me will explain more I’m sure.

Thanks all.
Stan, I have just retried key No 1, but it appears dead.
I will have to hope No2 lasts , but I am away until Saturday PM.

I presume they don’t need re coding after a battery change, but if it still doesn’t work after a second new battery, it will be the next step.

There are a few posts on here that suggest that the remotes can be sensitive to the brand of battery. Might be worth trying to get hold of a different brand. Duracell seem to get mostly positive comments and worked for me. 2011 5.0 S/C

+1 with Jomo, and check that you have put battery right side up (it has happened)
pic. of mine - I've just removed and put back battery and no problems.

Friday morning update.
Key No 1.
I have removed the new battery and re-fitted the original battery.
It works again, but obviously still giving Low battery. message.
New battery is obviously faulty.
Both are Maxcell.

I will buy 2 new Duracell on way home or ASAP.
Thanks for help.

I have just opened a brand new strip of 5 Maxwells CR2032 batteries, dated Expiry date 12-2024 and out of 4 of them in Fob No.2 not one works. That fob had a Panasonic. battery in which I have refitted, and it works perfectly, but is giving low battery warning.
I have just ordered a pack of 6 Panasonic CR 2032 off eBay and will retest when they arrive

Updated Monday 14th Jan.
I did in fact buy new Duracell type batteries, and as soon as I fitted them to both fobs, all was well .
Both keys worked perfectly with no re- coding.
