Custom Key RF transmitter
I have a peugeot 406 coupe 1998 and the key fob is well worn. It still works but id like to replace it with a new one.
I have a PIC, oscilliscope, rf, and RF kit.
Just now i have the key fob opened. Attached are the pics...
I thought it would be just a matter of finding the RF oscillator and scoping the data input to it.
I thought that this would be a serial stream of bits of some kind, that i can store and then replicate in a PIC.
But after i scoped the CAN shown in the second picture, all i saw was a SINE wave of about 10mV that trailed off to 0 after about 6 periods.
Surely this isnt the output stream is it?
Has anoyone got any idea's on how to intercept the data send by my key?
Note that the ICs shown are just what i think they might be from reading the packaging.
My stupid paint program wont type out the letter A or 8 so i had to replace a with @ and 8 with the string 8. I hope you understand what i mean
