Thanks a lot for all the details. Will check that tomorrow. Hopefully it is the issue.

Hey Gilbertd,
Thanks for the prompt response.
I think the issue might be closer to the first option from the ones you gave.
Im a new owner of the car from some 3 months and my first impression was that the remote is working only when it is very close to the car. Literally next to the doors.
Can you help please on what is this blue wire that can be disconnected and from where it is disconnected, expectedly?
I’ve both the workshop and owners manuals, so even a page to read is much appreciated.
Unfortunately, I’ve got a second key which is in a plastic bag condition. All things separated. I’ve seen above the ebay contact for repair services and will send a picture asking if it is repairable at all, as shipment to UK will be not cheap (I’m from Bulgaria). Hopefully it can be fixed, as it is either this or new from LandRover …..

The flashing red light on the fob when you put the key in the ignition, is caused by the coil around the ignition lock causing the fob to transmit an unlock code. However, the coil is very fragile and often breaks. In which case you need to manually sync the fobs.

With all doors and tailgate closed, put the key in the lock on the drivers door and turn it to lock, hold there and while holding it there, press and hold the lock button on the fob until the red LED flashes faster. Release the button on the fob and turn the key back to centre. Then turn to unlock, hold there, press and hold the unlock button on the fob, etc. Fob should then be synced and you can then do the same for the other one.

Hello all, sorry to steal the thread, but recently had similar case with disconnected battery and I'm, looking for help.
I've left the car unlocked for 2 weeks and after that the battery was dead. Charged it, was starting the engine and as I thought there was just a coincidence of uncharged batter had left the car unlocked for another week. Battery dead again. I've understood that the BeCM might not be going to sleep, thus consuming the battery quickly.
Charged the battery again, but as result I've my fob not remotely locking/unlocking.

The issue:
I've followed the above procedure from Gilbert and the fob was doing exactly what stated. Started blinking and then fast blinking.
However, after locking-pressing-fastblinking, center position, unlocking-pressing-fastblinking, the fob is again not able to lock/unlock remotely.
The engine starts without an issue and I'm using the key for lock/unlock, but would be good to have the fob working again.
Any help and ideas, what might be the case?

P.S.
When i put the key in the ignition there is no blinking and I suppose that the before-mentioned coil is dead.
