New Key
I have just purchased a new 2nd key from a Chevy dealer in the USA, the code was matched and cut, I can get the key to make everything light up on the dashboard but it will not start the engine, I then have to wait for the 3 minutes before I can use the other key successfully. Can anybody advise me as to what the problem is?

Sure sounds like the wrong VATS code to me....
The key has a resistor pellet on it. Measure the resistance on both sides of the key with a DVOM - and compare them. Are they the same?
. VATS key codes
You need to read the resistance of the key. If you have a digital volt meter, set it on ohms mode and measure the resistance of the pellet on your key. The BCM is programmed for a specific resistance value. The BCM measures the voltage drop across the key pellet. If it is within +-10%, then the car will start.
The 15 resistor codes are:
Key# Value (Ohms)
1 392
2 523
3 681
4 887
5 1130
6 1470
7 1870
8 2370
9 3010
10 3740
11 4750
12 6040
13 7500
14 9530
15 11800
Good luck....

Thanks for your help with the key problem, I have jest tested both keys with OHM meter, the readings are as follows
original key - 05.9
new key - 00.5
These readings are with the meter set at 200k, am I testing it correctly, have I got the correct setting on the OHM meter?
The dealer informed me that the key read No.12.
Thanks

Unfortunately I live in the UK and had the key cut last week whilst on holiday in Florida!!
