Hi. I lost chip from this disco 3. Does anybody knows where is key, and what tools can generate it? I took body computer (with fuse box from passenger side) out. inside is MC9s12DG256. am i digging at the right spot? What transponder should be used on this car? Thnks.

tmpro2, is the only one that can do it, you are looking in the right place.

I am putting this topic up. Got body unit out of the car, did not find any pic mcu, but found motorola. 9s12dg256. Maybe because this Discovery 3 is build in 2005. I read motorola. Can anybody see any keys, or know what tool can make key from this dump? Thanks in advance.

as u dint have a working key i think u need tmpro2 or u should order a dealer key

[mafia666]

well, Going to dealer tomorrow. 5 days waiting for key + around 300 eur for programming and key. :(

Sounds cheap in the UK going rate from locksmith would be about ?450

The only thing I could help you with is PIC unlock,but unfortunately I don't know the algo for the key adding,never even seen this car in person,it is rare in my country.

thanks. I ordered key from dealer. One more question for locksmith guys. where is the chip (transponder) in this key? Is it separete one, or soldered on the circuit board, where buttons for central lock are? I just have stupid idea, maybe i did not lost this chip and something else happened.

PCF7941,remote onboard.
If key doesn't work maybe it dropped,you should check coil resistance,and resolder PCB.

thanks. I will recheck it tomorrow. My key readers did not see chip, As far as i remember from last time. Somehow i believed, that i lost chip out of it, because key was half opened- not glued well after battery replace. Does key reader needs to recognize this key or its not transmitting while not in lock?

[simaservis1108]

It should recognize it right away.

its on the board for sure but if u want to add a chip for the car to get another key u can easily add a pcf7936 when u have one working key

i read it today - working. no idea what was wrong the other time. maybe it is sometimes working and sometimes not. i will try to start car tomorrow, as we are changing whole interior to disco 4 and many things are out. but, lads, thank you anyway.

p.s. how is with cloning working key on this car? what tool does it?

[PCF]

there is many tools in the chinese tools the skp-100 can do it in 10 seconds and it dont cost

Cloning Discovery3 key is not possible.Only way is to program spare key by OBD2.
