I think this is the only way to get one. It’s a strange and kinda scary process with a bit of trust involved and it will come via DHL. I’ve done it twice now and the tool is well known to be ubiquitous, so you should be OK.

Absofrigginlutely. If you get a D2 and are planning on keeping it a while, it is probably the best tool you can spend good money on. And you know where I live, so that heated windshield was a critical add to my former SoCal soccer mom kid transporter. My transformation of the HSE to being my winter driver is pretty much complete with the addition of the heated seat switches and the windshield when I did the A Pilar’s and cowl.

OK, you got me. I’ve programmed multiple keys in more than one D2, but I can’t remember how you do it without an existing key? Is the code there in the BCU and it shows up and you tell the key? It’s been a couple years and I can’t recall the procedure. I need to program a second key for the HSE and will need to do a couple for the Trail.

Oh yeah, for the OP: don’t forget to pay attention to the frequency of the key. My HSE came with an unprogrammed key the PO got from eBay and it was wrong and I couldn’t program it- even did a thread here on it- so do some quick research before you buy a key. I think there might be a workaround that has been discovered, but the coffee hasn’t fully kicked in yet this morning, so just order a Nanocom and do some research before ordering a key.

To the OP,

Some important details...

1) Your profile shows you are from the US. The US key fobs uses the 315Mhz frequency. Make sure to get the 315mHz frerquency instead of the 433Mhz for the Rest of the World vehicles.

2) The Nanocom needs the 6-character code for programming (see circled). This 6-character code is the specific code that the Nanocom uses to pair the specific key fob to the vehicle's BCU. This key code is on the label pasted on the factory transponder chip within the key fob casing. Best bet is to contact some of the popular LR wreckers (eg, Will Tillery) to see if he has any used original factory ones to sell. You can transfer the transponder chip into a new fob casing replacement and get new key blade cut (you can find them on Ebay or Amazon).




3) This is the video will help to explain why the 6-character code is needed by the Nanocom:


4) There are Ebay offshore versions that sell new fobs with new transponders which come with a long bar code string. This is a little bit of lottery to get the Nanocom to program correctly. If you want to try your luck with new chip versions from Ebay, make sure the seller is supplying the 315 Mhz for a US truck. Here is a video for reference:



Last note:
Nancoms have been known to fail the key programming without having updated Nanocom firmware. I read this somewhere when folks are attempting to do so after buying used Nanocoms. There are instructions in the Black Box Solutions (supplier's) website on how to update the firmware.

As acg says, I did not have a single fob for my D2 when I got it. I programmed 2 used fobs for a D2 from an Auto Wrecker into the BCU using my Nanocom. As stated, I used the 6 digit code stamped on the PCB inside the fob.

If you’re going to keep your Disco for any length of time, you’ll never regret buying the Nano.
