Why cant i remote start my car after the ignition switch repair?

SOURCE: Spare Key will not start the car.

no you don't have to have it done at dealership. i bought mine on ebay got it cut at walmart and it works. you need the two originals, turn the ignition to on and then off 4 times (i think it was) with the first two then put your spare key in and do the same. and it will work.

The timing is critical to this procedure, please read through the entire procedure before attempting.
Procedure:
1. Insert one of the pre-programmed transponder keys and turn the ignition to "on", leave on for at least one second (I wait until the red key symbol in the instrument cluster extiinguishes), remove the key from the ignition.
2. Within 5 seconds insert the second pre-programmed key and urn the ignition to "on" for at least one second but no more than 5 seconds (use the key symbol for this as well) then remove the second key.
3. within 10 seconds insert the new key in the ignition and turn the ignition to "on", if you are successful the red key symbol will illuminate then extinguish after about a second.

If you are not successful the red key symbol will flash repeatedly to indicate that you have inserted an invalid key. Remove the key, wait a minute and try it again, it took me a few times to get it perfect and I had done it before.

If that doesn't work, it sounds like a trip to the dealer.

Well, you can sometime catch the code again. Pt the key in the ignition and turn till the dash light come on (dont Start) then press and the Lock button while keeping the Lock button Pressed and turn the dash light off and put the key with the lock button Press for 10 second afterwards. If not successful first time try again. This should do it.
