ok so i have my new motor in the car, but i need to reprogram my keys, i have a 2003 s2 but i sold my original ecu a while back when i bought my aem, i now sold the aem with the turbo kit i had and now have an 01 ecu, now the problem is that everyone is saying that i need my original ecu to do this but, i have no way in getting my old ecu back nor the aem, how do i program my keys so that i can start my car?????

 

You should be able to go in to the dealer, have them punch in the VIN from the current ECU that you have installed and program your existing keys that are already cut to your doors and ignition cylinder.

 

When you go to progam the keys there is a option for all keys lost. The dealer should be able to reprogram all your keys to the new ecu. There is also a replace ecu option for reprograming keys.

 

Flatbed to the dealer with all your keys, so they can write them to the new ECU (they need the car to do this as the machine plugs into your OBDII connector)

 

You cannot make a coded key for an S2000 by the VIN. Only the cut, not the chip.

 

Flatbed, trip to dealer. Open wallet and shake.

 

ok, i used to work at honda and i forgot how to program keys so i needed some info on this, im having a buddy of mine come and program them for me. hes bringing the hds home with him so it should all work out. im so excited to bring my baby back out!!

 

ok still havent been able to get the hds home, but if all goes well my car should start right??? so no matter what the keys and the ecu will all work out right

 

another thing, whats the difference between the 04/06+motors besides the DBW and the crank sensor???

 

Question, can I just bring in my key with new ECU's VIN, w/o having my car there?
