TJECU CN900mini / test results & FAQ
Post on TJECU CN900mini & test results, FAQ, guide and more.
  1. TJECU CN900mini test results:
– Its confirmed cn900mini and toyokey can add 71 smart key
I tried it today adding a smart key to a 2007 Toyota fitz with 71 chip and it worked like a charm
– CN900 Mini is confirmed to read diamond keys with EML 10030A chip.
– Tested it on a Chevrolet Aveo 2012 – worked in seconds, no decoding. But that was to be expected. They use the easiest transponders.
–I bought the cn900 mini and appropriate ID46 chips. (5.5 € /piece)
Cloning worked for Astra H and Peugeot 307
-I still using version 1.13 and cloned few Opel 46 without hassle.
-Can clone ALL ID46 chips, i.e clone ID46 for OPEL(Vauxhall)/Peugeot/Citroen. Never failed on id46 to someone.
– I have copied about fifty ID46 keys with the CN900 mini successfully. Two times it failed (1x Renault Clio, 1x Opel Movano), because I can’t sniff data from ignition.
T5, 4C was never a problem. Sometimes it was not able to decode 4D. It starts decoding till 99 and then it stops.
I use 4C/4D carbon and different CN chips from Ali. I don’t know if original or not. They works all for me fine.
Firmware is 1.13 I don’t see a reason to upgrade.
For this money it is a small good tool.
– Here are the results of the TJECU CN900mini latest version (1.32) new “Partial 48 Decoding and Copy” function tested on VW Golf MK 4 , year 2002. Was Magic 2:
You have to update to version 1.32
Decode button is now working. After pressing the decode button, you have to sniff data from ignition lock of the car.
After that, decoding starts, and lasts for AT LEAST 20 minutes. You can see at the picture, that decoding is already 20 minutes in progress.
After that I left it for another 40 minutes. When I came back, the decoding was finished.
As you can see, the Secret Key is visible, but it shows “xxxx xxxx”
I don’t know what the meaning of those “x”-es is.
After the decoding, the function “Unlock” is working.
Also “copy” button is shown for coping to CN6 chip. I had CN6 chip to test, I ordered cn6 transponder for id 48 for mini cn 900 from here (Tested and it’s working (for version above 1.20).
The problem here is that decoding time is very long. Almost 1 hour.
  1. FAQ for reference
Q: I heard after this update, ID48 cloning stopped working.
Anyone can confirm
A: I can confirm it’s working fine

Qwhat new is in the 1.34 update comparing to 1.32.
And if it possible to copy key with CS protection (like in VW keys)
A: I can confirm it’s working fine

Q: So you guys say ID48 transponder cloning works, but what cars exactly does it support
It just reads the chip and asks for a CN6 – it doesn’t say anything about decoding and so on… So i guess it clones only the ID if the ID48 chip which is only the non-crypto info. Like TS888 supports cloning of older Chevrolet/Daewoo and KIA cars So it’s still nowhere near the functions of the Keyline tool and can’t even clone ID48 for old VAG cars around year 2000
Another thing I noticed – it can’t read “Megamos I” transponders.
– The ID48 was added just few months ago.
I did a Golf MK4, year 2002. Was Magic 2.
I plan to test also a newer car with CS protection.

I think, device isn’t cloning ONLY the chip ID, because it has decoded my chip for 1 hour.
So it has to be password or security bytes.
Then, where do you get cn6 transponder for id 48 for mini cn 900
Answer: I always order from here. It’s the guy who also sells CN900 mini devices. Tested and it’s working (for version above 1.20)
Q: I have a problem with my cn900 mini…touchscreen not working anymore when i select something it select another option
It’s someone that knows from where i can purchase touchscreen part
A:Open and check the connector of touch screen. CLean the pins with alcohol before plug in.
Q: So has 4C cloning fixed yet
A:yes, you have to use original cn1 chips, then where from do you get those original chips And how can you be sure they are original if you can’t test them on CN900mini before ordering
A: fake cn1 chips are very old
most sellers on ali have new chips cn1 original
i ordered 2 last times and have original
tested on nd900 (to a friend) and on cn900,cn900mini
