The key was stuffed so there was little risk in cracking it open to see if the battery or something simple was at fault.

I checked the battery on the multi-meter and it was still at ~3.2V after nearly two (2) years which was a positive surprise.

What I did notice was a lack of resistance from the lug attached to the circuit board as I lifted the battery up to make contact with the multi-meter so I held a patch lead in place and it started working again.

It is now soldered it in place and it works a treat. Just have to buy some superglue to put the fob back together.

Some pictures are included for your reference.

This has only just been done on the weekend so there could be other references you can investigate further to help you out.

Over to you and hope this helps.

Cheers PK

Thanks PK,

Already been through the Key and Fob process, and have a brand new one from the Uk matched to my VIN and coded.
Both the new and my original are now working. - Working to manually open the car and start it. Both wont work to unlock or lock the central locking. but are sending the signal.

Cheers,
Ben

Would a step be missing? I would assume the car would not start without the keys being programmed to the car?

Alarm was disabled by the mechanic so he could get in the car via the key manually and do the reprogramming process with the brand new key and original key. Also so I could manually enter the car and drive it.

I have already taken the original key apart and re soldered a new battery in, and it works perfectly fine to enter the car manually and start the car, and is charging and holding charge.

You can program the keys to the vehicle & all will work except locking & unlocking.
I still think the "Synchronising" of the keys to the alarm step is missing.

The car now knows there are 2 keys & has dropped out the replaced 3rd key.
But if it is not sync'd to the alarm it will not lock/unlock the vehicle.

I think that may be the issue with mine.

The day before I bought it the previous owner took it in to get two new tyres on at my request. However he didn't make it as the starter battery was flat. That was replaced, the tyres went on the on morning that I arrive and I took possession of the vehicle. Went to the shops to buy provisions for the trip home (Broome to Darwin) and it wouldn't lock with the fobs. Rang previous owner and he said they were fine when last used. Hhhmmmmm.

Took off for Fitzroy Crossing. Got there after dark and as the car park is under the motel rooms I didn't want to investigate too much in case I set off the alarm. The fob would not lock the vehicle but occasionally would unlock it. Intermittent response to the fob commands. Left it at that and continued on home.

Thinking it was flat batteries in the remotes I ordered a new fob and the previous owner also forwarded the one he ordered as one original was completely cactus. Eventually un-soldered and re-soldered and had new fob with new battery. Went to try with the vehicle and all I got was an intermittent response although after a few tries it would unlock every time. Went inside for two minutes came back out and the fob would no longer work. :censored:

Took vehicle in for service at dealer and got it back with an apology that TOPIX was offline and they could look at the remote fobs - rebooked 10 days later. :mad:

Dealer had it for a full day and the outcome was that they reprogrammed the remotes to the vehicle but they didn't work. Did the recommendations from the TOPIX advice and still didn't work.Tested remotes and both failed the test. Recommended two new fobs and coding at a price of $963.40 :eek2:

Much internet searching ensued...

Fuseable links? Negative

Fuse 43? Negative

Crook joint for the three wires? Negative

Started pulling the roof lining off but ended up giving up in frustration and disgust before I found the alarm receiver to check if it is getting power or has an earth issue.

The red alarm light on the dash flashes every 2 seconds to say that all is well with the system - it just won't talk regularly to the remotes and in particular lock the vehicle.

I will earnestly endeavour to obtain approval from the other half-owner of the vehicle tomorrow to expedite the purchase of a Nanocom to help in diagnosis of the issue.

One question I have is - How does one synchronize the fobs?

Any other thoughts or suggestions gratefully accepted...

I was curious as to whether you can program the key with a Nanocom - I bought one in the last group buy. I logged into the Nanocom forum and found mention of a Beta version for the D3 so I have asked whether it is available for the D4. They're offline at the moment. I'll report back with their answer.

Check back on the Nanocom forum. I haven't played with this function but it appears to be in the latest release (1.30).

My reading of their information leads me to believe it will.

i can't help you but only sympathise. When I purchased my D3 the key was held together with sticky tape. I got two new keys as part of the deal. It was a LR dealer. One day I got keys synched by LR dealer in Townsville. Cost $80. Made Cairns dealer pay. The third key still works by the way.One day I was setting the lights on function on the key and it locked itself completely overnight. My manual key doesn't work. I went out in the morning and it opened first time. I was very scared to lock the car for some time after this. I now have a Nanocom and it does have a key function. I am very hesitant to play with it after my last experience. Other than breaking the window they are impossible to break into. I now consider my D3 to be alive. It has a mind of its own. Can be very frustrating.

Thanks Carl.

I waiver between thinking the fobs need syncing and an electrical issue in the vehicle (including even a faulty receiver). Being uncertain is worrying as you have said.

I asked Black Box the same question the other day as I have a key fob with power that doesn't operate central locking. This is his response:

"The instructions for the D3 Key Learning are displayed on the Nanocom screen. You must proceed as the Nanocom instructs you.
The D3 Key Learning function is available in the Beta versions only.
Used keys might cannot be learned to the vehicle as the function supports only new keys, but maybe you can proceed with a re-synch of the already received keys.
Please note that the key learning function is not officially released so it may not perform as expected.

Kind regards,
Adrian"

I'm hoping to give it a try today. I note that the latest firmware for Nonocom (1.3) has D4 key learning feature (I have a D3).

Will let you know how I go.
