Apply power to tow electrics or get someone to crawl underneath and apply power to the starter - then use the key fob as normal.
wouldn't there be a current limit issue for the fuses ?
Can the bonnet be opened possibly ?

If the aux battery was installed correctly putting power through the rear plug will only charge the aux battery as the switching mechanism between starter and aux battery is normally controlled by the starter battery to protect it being run down via the aux items being run off the aux.
If you cannot unlock and open the passenger door then you are in a pickle - skull drag the car away from the wall. However if you can unlock the door and get it open just a bit you might be able to rig up something to pull the bonnet lever and then open the bonnet and recharge.
This highlights how the computer nerds who design these things need to get a reality check - also without pulling half the console apart you cannot get the gearbox out of Park, the handbrake remains on and you cannot open the tailgate
Other wise a skull drag away from the wall.

charging the battery via the tow electrics is an interesting idea.
Yes I had thought about what it would take to move the car to the other side of the driveway (say 1 meter or 3 ft) and its actually a monster job.
The landrover tow stuff was in before I put the secondary battery so there is no connection between them.
Considering that there are 2 (1 white & 1 black) sockets which are we looking at ?
I can plug into the black, but cant remember a continuous power ? so which pins are we looking at ?
i have never considered the white and don't even know if we can get a plug here in Australia.
-----
ok I have now looked at the "standard wiring" for the 12s socket, now to try an located a suitable plug locally.
Seeing the battery is flat, I suspect testing of the socket before applying power will probably be useless.... any suggestions considering this is a land rover we are talking about ??

With a car locked, keys out of the ignition and no lights on I do not see how using the standard LR wiring either black or white socket would allow you to charge the starter battery.
I do not have an aux battery in my car but I do have an anderson plug at the rear connected direct to the starter so in my case I could charge the starter battery from the rear plug.

Garry,
Charging via the tow electrics is very common over here. The forum shop even sells readymade leads with the popular Ctek plug at the end for both 13 pin and 12S type sockets. Even without a proper plug I have opened many a car by applying power to the pins for long enough to operate the locks. There is a wiki article on the subject too. It takes seconds to unlock the vehicle this way but the starter cable remains a good alternative option.

Good, then use that. I use my towing electrics every few weeks to charge my battery. As Robbie says its very popular here

Excellent Information.
Many thanks.
Only problem I have is try to locate a 12S plug. Ebay and elsewhere, I can forget the car till at least Feb 2015.
I did some measurements in the socket, max voltage seen was 2.79 so looks like a serious battery failure.

That is a very low voltage so thoughts start to turn towards the alternator as the root cause.
As said, you don't need a plug if you can find a way of briefly applying power to the pin just to get the doors open. The ground can connect to almost anywhere on the chassis.
Lets see how it goes - good luck!

Opened my old D3 through towing electrics with a power tool battery (fully charged ) with a couple of wires to the connections gives just enough power for the locks to pop , sure someone can explain better as it been a while

I applied charger thru a bare (foldedback) wires to pin 3 & 4.
you beauty !! immediately able to unlock.
So pop'd bonnet release and relocked.
will leave charger connected overnight.
I just had a look @ my last registration service/inspection notes, and they did mention that the battery "is low" and needs replacing.
Aug 08 build, so 7 years is not too bad. Which means 6.75 years on the secondary which is the best I have ever achieved yet on any vehicle for me.
Many thanks to all of you for the assistance.
Yes I will make up an appropriate lead and fix it somewhere "under" but external to the vehicle

Glad it worked and hope the knees were ok.
As you have seen, it really does take seconds to do so I hope this aids the confidence of others who may find themselves in this pickle.
