[rebelu]

i have a car alarm, magicar fai-300n, with a broken 16f84, can anyone pls help me to program a new pic? if u could send me the hex file it would be great, thank you

Sure, I'll send you one when I get one.

PIC's supplied in manufactured products will most certainly always be code protected. I seriously doubt that they would have used the "F" series. They would rather use the "C" series. Cheaper, once off programming etc.

I think your best bet would be to contact the supplier, and try and negotiate for a replacement, (if the IC got damaged due to some unforeseen incident, and not by someone trying to hack the code )

You better contact with the supplier as SPDCHK tells. But the problem is how only the PIC is damaged, unless you tried to remove the PIC for hacking or cloning a similar circuit.
By looking all the features it needs a big program to do so.

Tell the truth for your supplier I have tried to hack this chip but I couldn’t. Pls give me the hex file for cheaper amount….
In my opinion you can buy security devices for cheaper amount today.

I didn`t want to hack it, i wanted to connect my cars central locking straight to it, because my car had central locking with a remote, and afterwords i added the car alarm with a second remote and u can immagine ... one key two remotes. The thing is when i tried to connect my central locking trough a rellay instead of the radio receiver from the car alarm, the pic died . I have a friend with the same car alarm, he gave me the pic to duplicate it but it was protected... , i haven't tried to hack it because i don't want to damege another pic... so please if u know how to assamble a program for the pic in a car alarm pls give me a msg.

If its code protected the only way your going to get another copy is to buy another pic from the supplier. There's no way anyone will have a assembly file which you can use to reprogram the pic.
