The car is not reading the key and thinks someone is trying to steal it. Try another key or see a dealer.

It seems that you have a loose wire, bad connector or perhaps the main computer itself that is causing a problem If the shop is not seeing any codes, or codes come and go, likely I'm right...but someone is going to have to actually do some intensive testing to find the real cause. You can likely get another computer from a local scrapyard far cheaper than what the dealer will charge you...as far as wiring, you need a good accurate schematic a good volt/ohmeter and lots of time to trace wiring. When checking connectors test the pin, then probe the wire going into the pin...often the problem is where a wire meets the backside of the pin, either corroding or breaking..This also applies to any modules such as the security system...what you see on the dash does not always tell you that connection to components is good. This is not a "fix, but rather, a direction to go in. (exactly what I"d need to do if I was there)
Right now, everything is suspect including fuel system, till you rule it out!!!

had the eact same thing happen on my diesel and it turned out to be the alternator which had fried oine of the batteries.... you could put a charge on them and it would run for a week or ten days and then nothing.. clean the cables charge it up and it would go again... finally it just stop taking the charge and I look deeper and replaced the batteries ran fine for two weeks then dead again... alternator finally finished itself off... problem had been a little intermittent till then.. good luck
