Replacing the Smart Key Battery

I have got a note on my dash saying the the smart key battery needs replacing.

Is it just a matter of taking the old battery out and replacing it?

Does anything need to be done BEFORE i remove the battery?

Do i go to LR to buy a battery or get one from elsewhere?

Coin battery from eBay about £1 each for Duracell.
Pretty sure it explains how to change them in the manual

Will the Duracell DL 2032 do the same job? Use them in the garage remote.

With the numbers being the same I would think they would fit but not 100% sure

A little be confused. I have 2008 D3 model and until today I don´t have any problems with the key batteries, only 2 years??

I see in the photo that key in D4 is a little different from D3, there is not release bottom.

I thought the D3 charged itself up in the ignition slot - hence the need to toggle the usage

Could be wrong
 D4 HSE - Aintree Green
D4 Orkney my13 - gone
Stornaway D4. Gone, Didn't like it at all
D3 silver manual. Loved my first LR

Yes, the D3 key fob is a sealed unit with a rechargeable battery soldered in place; induction charging when the key is close to the ignition barrel. As GlosBoy says, one needs to alternate key usage to keep them both charged. I have one original key (7 & 1/2 years use), and one replacement (other lasted about 5 years). I did perform a battery swap on the failed one, but it was the charging circuit that had failed, as the new battery lasted only a few weeks.

interesting.

What I do is change keys every two years, and until now almost 5 years without problems.

I know a friend who change battery and and you have to be very carefully to open

D4 uses a totally different system to D3.
CR2032 battery for D4 is a replacement and not a rechargeable as with D3.
A better system in my view.

Yup, my warning came on yesterday after 29 months and 24k miles. I use the same fob all the time.

I just got the "low battery" warning and I'm trying to change the battery. The key looks loke the one from the handbook but it does not open fully. What do I do wrong?
