Extract from LR workshop manual:
Handset Battery
NOTE: Do not remove a battery until you are ready to install the replacement. Always fit a Land Rover STC4080 or a Panasonic CR2032 replacement battery.
1. Unlock the vehicle and disarm the alarm system.
2. Turn the ignition switch to position 'II', then turn to position '0' and remove the key.
CAUTION: Do not allow moisture to get inside the handset.
3. Carefully prise the handset apart, starting from the keying end. Avoid damaging the seal between the two halves of the case.
4. Slide the battery out of its clip, taking care to avoid touching the circuit board or the contact surfaces of the clip. 5. Press and hold one of the buttons for at least 5 seconds to drain any residual power from the handset.
6. Fit the new battery, making sure that correct polarity is maintained (+ve side facing up). Finger marks will adversely affect battery life. Avoid touching the flat surfaces of the battery, and wipe clean before fitment.
7. Reassemble the two halves of the handset. Operate the Padlock symbol button at least 4 times within range of the vehicle to resynchronise the handset.

It may be me but I'm not sure - are you wanting to just change the battery or the actual key fob? Defender 90XS SW

Works for me, change mine every 2 years. Sometimes forget and just changed the battery without following instructions. Still worked ok.
Just do one key fob at a time, and make certain it is working ok before doing the second.

Oops - both times I've done it, I've just ripped out the batteries and put in new ones.

When mine went into the Land Rover dealer for its two year service the mechanic came out just before I drove away and said sorry but he'd left the fob batteries on his bench but no problem if I hung on for two minutes he's go and get the batteries and swap them over. He did this in the car park and both fobs worked perfectly ok so ever since I've just opened up the fob and swapped them over with no problems. Defender 90XS SW

Just noticed that when I unlock mine, the indicators do not flash - I seem to recall this indicates the battery in the fob needs changing, but can anyone confirm please? Euro-Leafing to infinity and beyond.....

thanks for this, worked a charm just now after 'oh s***' moment of removing before checking if there was a procedure, fortunately had a second set so could do the steps.

do you have to seat in the drivers seat while changing the battery fob? Or I got this totally wrong?
