Did you erase the code and then it came back? Check with auto parts store to see if they say 1 or 2.

those are all codes for the shift solenoids in the transmission. very easy to get at.

my 99SW did not have coded keys, and it had remote door locks which seem to go along with coded keys. i assume a call into a GM dealer which services Saturns could answer this question if you gave them the VIN. do a google search for saturn service in your area. there will be some hapless GM dealer stuck with doing the maintenance on Saturns and they should have access to a data base which will provide that info.

go to autozone they will give you a print out wile the thing to check. bobg22

well the only way to unlock the radio is this,,,there is a 4 digit code stored in the radio you need to get it from the radio,you must press and hold radio preset buttons 1 and 2 for 5 seconds and then a 4 digit code will appear,write down that code and respond to me so i can get you the unlock code,,only dealers can get the unlock code,i need to call saturn with that code thats in the radio to get you the unlock code,and then you enter the unlock code and you good to go,,,or you can take it to saturn and they may or may not do it for you for free,,but if you want just get back to me with the unlock code

What Year is the saturn?? I think if my memory serves me well that code 84 is an internal ECM communication error.Hope this helps
