I really need help - Central locking/Alarm/Key fobs etc etc

Hi Narangga

I've just looked up the IID Tool from Gap Diagnostics & Key programming is listed.
https://www.gap-diagnostic.com/products/iidtool/

Although it's still unclear exactly where the issue lies, you would get a great diagnostic tool at the same time. .....

Unless you've already got the Nanocom

Let us know how you get on.

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.

Thanks. I wasn't sure from reading their info but thought it might.

Would be good to hear how you get on.

Thanks Richard. I lent toward the Nanocom due to the experience many on the forum have had with them.

I'll let you know what transpires with my fob issue though.

Rufusking replied to my query on the Nanocom forum and pointed me to the relevant instructions for the D4. From what I read, there are two actions available as shown below.

Key Learning Application Functions:

Function no.1: Read Key(s) Status
This function shows the number of keys that are currently learned to the Keyless Vehicle Module (KVM) and the
number of those keys currently present, for which you will need to place all available keys inside the vehicle. The
number of non present keys can be deduced by deducting the number of "present keys" from the "number of
programmed keys".

Function no.2: Add a new key
This function exclusively learns a brand new key to the Keyless Vehicle Module (KVM) adding it to those already
learned. It cannot learn previously learned or used keys.

I gave the key learn function a go tonight on my D3 using a Nanocom. I have one fully working key and remote and a second key that the remote does not work but once I'm in the car will start the ignition. After contacting the guys at Black Box to get some pointers I tried re-learning the key with the inoperable remote. This is where it got interesting.

The key learning feature is in the Tools menu on the Nanocom. You are given several options: Learn New Key, Learn 1 Key, Learn 2 Keys ... up to 4 keys I think. As I only wanted to try and fix one of my keys I selected the Learn 1 Key option. I followed the prompts and all was well. On completion I removed the key to test, tried the remote but no joy with the central locking. I put the key in the ignition and it started :D so I figured I must have an issue on the PCB with the remote. No problem, I'll pull it apart some time to investigate. :confused::confused:

I did however encounter a problem when I went to use the original fully working key. No remote anymore and it wouldn't start the car!!! :eek::eek::eek:. Mild panic set in but then I thought - the Nanocom must have disabled it when I made the selection to learn only 1 key so I started again, this time selecting Learn 2 Keys. I needed to use the key with the broken remote to start the process off as this was the only one still coded to the car. Again, following the prompts, I put the second key in and everything programmed fine :D:D:D. I'm back to where I first started but at least I know the learning feature works. :)

Now to either fix the PCB or find a new replacement remote.

Thanks for the info Oztourer. Have you replaced the battery in the second remote?

Our issues vary in that both my remotes only operate intermittently and when they do will only unlock the vehicle - never lock it.

You were obviously able to program the key with the Nanocom, but my question still is - How does one synchronize the keys??? :confused:

One thing I did not mention previously is that when I push the button on the dash to lock the doors, all locks activate. Once I have then closed either of the front doors that I had opened to do that and then go to the drivers door, it opens by pulling on the handle. :censored: I gather this is due to the lock sequence the door found itself in when the starter battery was replaced and the remotes stopped functioning.

Either I find out how to sync the remotes or accessing the alarm receiver is the next step :(

I've found my problem!!:):)
After not being able to get any response with my Nanocom trying to re-learn my non-functional fob remote, I took the plunge and cut it open (the button covers were ruined anyway so I had nothing to lose). There are several posts around describing how to open these fobs but I just took to it with a sharp Stanley knife, cutting through the join seam around the perimeter, taking care not to to cut too deep and also not to slip and cut myself!! Looking at the PCB under a magy-lamp I found a cracked solder joint on one of the battery terminals. A quick dab with the soldering iron and voi la - one resurrected fob remote!! This simple exercise has saved me several hundred dollars on a new replacement. :D:D

Attachment 100638

Opening the case destroyed it so I'll have to find a replacement on-line. Can anyone recommend a decent replacement case supplier?

Hope this helps someone in a similar predicament.

Cheers

I have seen plenty of key cases on eBay.

Good to hear Oztourer. Indicates why only one was not working. I did buy a new case off eBay but that seller does not have any at the moment.

I also inherited another case with the vehicle which is obviously a genuine one (it has a Land Rover button) but the generic one I bought is of similar quality in all aspects - e.g. plastic, key, spring for the key etc.

Well despite numerous internet searches I was not able to find any instructions on how to sync fobs for a D3. Various other Land Rovers but not mine :mad:. Nothing on TOPIX either.

This morning the headlining came down and I was able to determine that the receiver is getting 12.0V from the plain green wire and 12.53V from the green & yellow wire. Voltage at the starter battery at the time was 12.77V.

I sat there for a couple of minutes and the voltage for either wire did not fluctuate but remained constant.

I cleaned the earth on the receiver and also the bolt head and put it back in place and still no remote locking - only the occasional unlock from the fob.

Monday I order a new receiver and if that does not fix the issue I'll go back to the dealer to order ONE fob, have them program it and then see what happens :(
