I just bought a new keyless entry key for my Scion Tc. I programmed it so it does lock and unlock and the panic works but the car wont start. The ignition works and it sounds like its going to start but it doesn't. Can anyone help me out?

 

sounds crappy man

 

what do u mean u programmed it? that how it comes stock.

 

I programmed the key to the car so it would lock and unlock it. but it doesnt start the car all that happens is the ignition keeps winding over and over

 

oooh u have to have a dealer set up the immobilizer for u

 

^^^ yep x2

 

I'm guessing I can't do that by myself in any way? Thats prob a really stupid question

 

^^ x2. The dealer has to program the key so it has the code for your ECU. Without the correct code in the key the ECU will not let the engine start.

 

teh dealer will charge u $$$$ for doing it too.

 

Nah, you could do this yourself if you have 2 keys that work... my gf had this problem with her Focus. First, you put in a key that works, turn the car to ON, turn it off, take out the key and put in the second key that works... valet key or whatever. then turn the car to ON, then take the key out. Third, put in the new key that won't start the car and turn the key to start, and it should work. That's how it worked in the Focus, anyway... it's worth a shot.

 

No, the ECU learns the key's code.

 

Thats how Ford does it, I know Some Chrysler's use that style with more stringent timing. I don't know Toyota has a way to customer program the immobilizer though.

If it works though let us know.
