Hello, you are the expert! You tell me can or cannot copy. I only know "Copy and paste" in Winword only.

Please explain what is the difference between EML and PCF transponder? What are the working principles of each device.
You also mentioned about Megamos, Temic and T5. What do they do?

OK, this chip is a micropower step-up DC to DC converter.

EML is attach to remote and PCF is not attach to remote. MEGAMOS and TEMIC are build for program 1 time and can be copied (cloned) into T5

. MEGAMOS can be emulated on PCF7935. The info that i get dosent stated EML can copy to PCF. That is why i am asking you to confirm with locksmith. Or else wait my key programmer reached my hand then only can know what is going on.

Why is the EML attached on the PCB? I thought the transponder are suppose to be activated via wireless or radio frequency.

I dont know any locksmith other than the one recommend by alex.

 

[Alex5522]

I saw the Diamond shape key got a very big inductor for convert the signal to electric which able for you to charge the battery but my key is not the Diamond shape key. The inductor is inside the transponder so dont have inductor at the remote circuit.

Finally my key programmer has reached my hand already but still waiting my another 433 MHz uncut key in order to do the clone.

Now both key programmer and uncut key already on my hand i can start clone the key. Will update the result later.
