Of all the electronics in the car, one part that is almost certainly in need replacement is the immobilizer box under the driver's seat. Even if it is good, the odds of finding a matching key stashed somewhere in the car are on par with finding a talking unicorn in my back yard. Tonight I was looking through the PET to see if any of the parts I have will work in the 04 SE. Not as a fix, but to at least power it up as I figure out what works and what doesn't. Of my 3 sets of key fob/ DME/immobilizer, none of them were the right part number. Curious what other cars I might source it from, I typed it into Google. "99661826203"
Unbelievable... one on eBay from an '04 S SE with 3 keys, for under $500 shipped. No worries of repairing my set or flashing a SE tune to another ECU. This should work. ...hopefully the rest of the car will eventually work too.
