Hi

I'm a happy owner of a 2015 Discovery Sport HS that for 5 years has been surprisingly reliable. Over the weekend though, just when I needed it, I found neither key fob would open the car - and my curry was getting cold! I discovered the physical key, and got the car started and off the drive, but I'm now told by my local Landrover garage that they cant diagnose the problem until March. Before you ask, I checked the batteries in both fobs and they are fine. In fact the car had behaved perfectly only that morning. I have tried putting the fobs under the steering column, and that allows me to start the car OK, but my wife, who needs the car for grand kids, doesn't have the strength in her hand to use the physical key in the door. So, in my long winded way I'm hoping someone has had this problem before and can point me in the right direction to cure the issue. Is it a fuse? a wiring issue? I've read it might require a reset of the car's electronics. Any help would be gratefully received.

You could try to find a local LR specialist rather than a dealership, the 2015 has fairly standard diagnostics so should be easier than the newer cars to work on.
The standard "turn it off and on again" for modern cars is to disconnect the battery and short the disconnected leads together for 30-60 seconds. Does mean that you have to reprogram the windows, but that just involves sending them down to the bottom, release the up/down button and then select down again (while they are down). Then repeat at the top.

When you said you checked the fob batteries, what voltage did they read?

With that age of car and if the fob batteries have never been changed then it is likely the batteries.
They take CR2032 (2x Panasonic for £1 on eBay). How to is here:

For reference, a brand new 3 volt battery has about 3.3V. When the battery drops down to 2.8-2.7V it is considered dead. At this point you’ll get a replace battery warning on the dash. So if you experience key fob problems then you are probably close to the point of replacing them but not quite to get a warning.
