Well I'm computerless so this is via my Palm so I'll make it short and sweet. I'm having trouble with my Ford alarm (the upgrade one that actually chirps and has motion sensors) and can't seem to get the dang thing to arm. I've taken my dash apart, checked fuses, messsed with everything, no dice. Most I've gotten it to do is chirp and unchirp but still no arm. It did arm one time and go off but then stopped after that. My mechanic said he's not to familiar with them but could look to fix it (since it stopped working after he took the dash out to replace the heater core) if I had a manual for it. No manual. So I'm just trying on my down time.

So to my question, if I go to a junk yard and find a new alarm module, could I just try it or are they vin locked?

If anyone has any suggestions on how to fix or reset the one I have now I'm more than open to any ans all suggestions. I'm just stumped right now and so was my certified Ford mechanic.

P.S.- if I take the fuse out, it chirps, then goes off when I put it back in, then I have to turn the truck on to make it stop. it then does a series of about 15 chirps and stops. Still doesn't work after that.

Thanks
