Alrighty - recently my 8 was broken into and I realize there is a high probability of my Valet key being in the briefcase which they stole. I called a few dealerships and explained and they said two options exist: 1) spend 1000 dollars and rekey/recode and change the igntion and tumblers in the door/trunk etc. or 2) reprogram the keys such that the valet key will no longer start the car.
for the time being the car is in a safe location (body shop far away), I have my two original switchblade style keys as well just no valet key. My main concern is that they wouldnt be able to come back use the valet key and DRIVE off like they owned the car. I do realize they would theoretically be able to get inside the car but my inside is clean and bare of anything that isnt stock and comes with the car. I'm going to have a hard enough time paying for the laptop so as much as I would love to get the car rekeyed with new tumblers I cant.
Now I was in a conversation with StealthTL and he's been very helpful in letting me know apparently I can recode my own key and not have to give the dealership 150 dollars as they quoted me on the phone. (one dealership actually said "dont worry the valet key doenst start the car) ummm WTF! i hung up on them.
Anyways - StealthTL not to doubt your knowledge I just wanted to confirm your idea with as many people as I could since (theoretically) if you were wrong they could drive my 30K RX8 away in 5 seconds with no smashing/cutting/flatbed.
He basically said that I can use http://www.rx8club.com/showthread.php?t=43873.html that method to re-code my two key FOBs. I was under the impression that an entire new code had to be programmed in at mazda to successsfully make it such that the valet key will not start the car. I hope I'm wrong because that would save me a bunch of money if i could successfully do it myself.
----------------------
PROCESS THAT I WAS TOLD WORKS to get the result I need of invalidating the valet key:
The computer sends a query to the chip, the chip replies with it's code #.
If the code is on "the list" the car is allowed to start.
When you start the reset process (door button etc.) you are re-writing that list.
If you successfully go thru the process, and your keys work, any key that was not in "that process" is no longer valid. If you buy a new key, you get it cut, then go thru the key registering process, and include the new key after the minimum two valid keys.
-------------------
if this is true - awesome that way I can do the recode myself and not have to worry about my car being driven away in the night if they ever came back. Any and all thoughts are appreciated.
