Key fob battery low warning light came on , replaced battery and still same, checked new battery with voltmeter (old one in depths of bin) and showing as 3v so good to go . Put it back in fob and now all fine and no warning light. Is this likely to be a fob issue if it crops up again in near future or vehicle issue ?

With your model because you do not insert the fob it is not charged up so you will have to replace the battery every so often, I find with mine about every 18 months but it depends on your usage. If you do have two keys remember to switch between the them. MY13 HSE Lux Santorini Black

I have a suspicion that the FL2 sometimes 'remembers' faults.
Normally clears with a cycle or two of - fully double lock, leave a few minutes, then open and start -

Don't know why, most likely needs to reset electronics. FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)

I did have a fob that was flattening batteries within 2 weeks. Went through about half dozen batteries. LR replaced the electronics (was still within warranty).


It seems to be 2.97 to 3.0 volts & you get the battery replacement warning. Procrastination, mankind's greatest labour saving device!
