Vats Pass bypass 1989 Chevrolet Corvette

my friend recently bought this corvette, he didnt get the key with it. i ended up making all 15 key values for the vats pass security system, i 1st verified that the system was working, we did have to pull the cylinder lock for the ignition out of the steering column, once i had the 2 white wires off of the cylinder lock, i began hooking up resistors one right after another 1st i waited the 4mins exactly with that didn't work went thru all 15. i tested the voltage coming from the vats module it was fine. so i waited 6 minutes this time, to my frustration and amazement it was the 8th value i tired. the car hasnt been running in over 2 yrs. we put fresh gas n a new battery checked all the fluids before we even started it. we did find that it has a cold start issue also. it does need a full tune up n service on the transmission n engine oil n coolant. towards the end of the day we decided to drive the car home after making sure the brakes worked and it didnt overheat n the transmission was shifting correctly. here is a video i took of it running on the 1st fire up.n i used 1/2 watt resistors also from radio shack. here are the key values. the key value was 2370 ohms which i had the resistor value at 2330 ohms.
