Ok I bought a 2003 rodeo I test drove the day before .......so the owner lost the key the day I go to picked it up replaced the ignition won't start with the super chip. Lock smith comes out and his programmer won't communicate with the ECU to get code for immobilizer finally the question I have do you think this will work to program the immobilizer to learn the new key
 
There is a megamos ID48 security chip in the ignition key with a code stored in it. There is a code stored in the Immobilizer module (93LC46 EEPROM) security chip. There is also a security chip in the Engine Control Module (ECM).

To start the engine, the code stored in the Immobilizer module security chip (93LC46 EEPROM) and the ECU must match the ignition key code. The locksmith needs to read the code from the Immobilizer module (93LC46 EEPROM) and load that code in the megamos ID48 security chip in the ignition key.

If you can't retrieve the security code you have a 4000 pound boat anchor.
 
Hope this is the right thread to post in!

I got a 2005 Rodeo earlier this year and the car's been great for what I want it to do. Been thinking I need to get a spare key + fob and of course there's no way of getting one these days. So, I've been looking at the specs and see that my original Rodeo key fits profile TOY43R and the fob chip is on ID48.

Could someone kindly advise me, is there an alternative that would work (to ADD) as a second key + fob combo? Perhaps something from the dmax range or some other generic thing? Not urgent, just like to have a backup in the event I lose my car keys...
 
You can buy a TOY43R ID 48 blank and have an automotive locksmith cut the key to fit the ignition. Once you verify the key will unlock the ignition and doors the locksmith can retrieve the Immobilizer security code from the original key and copy it to the new key.
The Megamos security chip is a ID48
