Freel2,

My daughter just called me to let me know that the LR2 wouldn't respond to the key fob.

I walked her thru how to gain emergency access.

Video calls are a wonderful thing.

I loaded up the PowerfulUK video on youtube.


Some interesting things to note

1. For US LR2s the emergency key location is on the drivers side not the passenger side (or said another way it on the same side as it is in the UK, I had no idea I never used the emergency key.)

2. Opening the door immediately set off the alarm

3. Docking the key and starting the engine silenced the alarm

4. Note: none of the buttons on the key fob worked

5. The Engine sprang to life so the main battery seems to be fine (it is new)

6. Because my daughter came home for a holiday the LR2 hadn't been accessed for 30 days Nov. 4th to Dec 4th


Questions

A. What got disabled? (I suspect that it is on purpose to limit battery drain)

B. Would Locking and Unlocking the doors reset the clock or does the engine need to run? (this has never happen in my 14 years of ownership but I've never gone 30 days without accessing or running the LR2)

C. In the US we don't have the double lock that is standard in the UK so I can't answer the question about double vs. single lock. (I suspect that my LR2 is essentially in single lock mode, but I could be completely wrong about this)


Any help is greatly appreciated

Here is the video for anyone curious



Take care

Paul

PS in case you are interested it exam time at my Daughters University and Noise discipline is being strictly enforced. I guess we should have told the Land Rover.

At least she didn't have to lie on the roof of the car & reach down to manually unlock it & reach back across to the other side with a stick to open the driver's door. Could have been embarrassing! Procrastination, mankind's greatest labour saving device!

Lightwater,

Where I come from we call what you described "Talents of a misspent youth"

I did make me laugh.

Thanks for sharing.



Update

I asked my daughter to keep the engine running for about an hour to recharge the battery. She drove to the store and her friend went inside and then to the drive thru for some food.

The key fob works again.

Everything is back to normal.

And best of all my daughter has learned her first " Talent of a misspent youth"

Take care

Yes car goes into deep sleep after 28 days with no use regardless of the state of the battery charge, and has to be opened manually. If the car is left for long periods and the lock is on the passenger side don't park with that side flush to a brick wall !

Periodically unlocking and locking the car doesn't reset the timer, possibly putting the fob in and getting the dashboard lit up without starting it might but I haven't tried that. 
Hung like Einstein, smart as a horse.

Had a similar issue with a Ford CMax, possibly same ford software coding.

Then found door locks and boot lock had seized from lack of use (well you don't with remote do you).

Had to break quarter light to get access to use key in ignition to reset things.

As well as not pariking up to a wall, you should periodically check the manual lock is working, and especially if you are leaving vehicle for a while. Andy

Do you not remember Axle and his sorry tale?

Here's how he solved it. I warn you it involved the use of washing up liquid - and his wife!

From previous experience, I have found that once the door is unlocked, and the car can recognise the key fob, the car will start when you press the button as normal. The alarm will stop also with a normal start procedure

The Battery Management System conserves the battery by shutting off all systems except the Perimeter Alarm, normally after a maximum of 28 days idle. FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)

I have not had this issue but it's good to know that a long drive after getting the vehicle open appears to rectify the keyfob problem. It's also good to know that you have no parasitic drain issues as 'she' started up immediately after 30 days of inactivity.

Ian,

That is a great read.

However I am trying to get my Daughter to learn the talents of a misspent youth.

Where I come from we would say that you swung the bat a bit too hard (Baseball)

A better analogy for the UK might be "The was a hell of a kick, past the pitch, over the stands and into the car park"


We need to keep this at the beginner level not the master class.

Thanks for sharing

I am still laughing about the "Dish Soap Solution"

Thanks

Paul

If the remote handset rolling code loses synchronization with the CJB, the remote handset functions will not operate.
Synchronization between the remote handset and CJB is restored by starting the engine with the affected remote handset,
and allowing the engine to run for a minimum of 6 minutes.

It's all very well not parking up against a wall, but a lot of garages are too narrow. We have a guide so the car can get as close to the wall as possible without scratching it, so I can actually get out of the car.

We measured our garage before we bought the car factoring in opening the driver's door.


The manual lock should be on the driver's door. Procrastination, mankind's greatest labour saving device!

Good to know about this, my daughter also might take the LR2 to college. But also LH drive here so the manual lock should be accessible. Axle's RH drive dilemma was an entertaining read, although it didn't seem funny at the time I'm sure.

I used to park a car at the airport for weeks due to my job, I'd install a quick-connect fitting on the battery pos terminal so the battery would still work on my return. Interesting that LR thought to address that.

Freel2,

I have found the solution to the problem

Apparently the root cause is

A lack of Synchronicity


The solution is almost obvious


I can't believe that I missed this at first

Hey, I actually owned that album when it first came out!!
