key fob problem

[03tahoejoe]

So yesterday I bought my 03 tahoe that came with a new fob that just needed to be programmed. I followed the correct procedure on programing it to the truck but after finishing the process the fob does nothing. Could it be the fob or is the issue with the truck? Thanks in advance!

Did you buy it from a dealer or a private owner because if you bought it from a dealer have them program it for you otherwise it may be bad...

Used car dealer. Supposedly the fob was just bought before I bought the truck. I shut all the doors, held the unlock button and cycled the key twice, let go of the button before the locks finished cycling, held the lock and unlock button on the fob for about 3-4 minutes before the locks responded, turned the key back on to end the programming procedure, hit the lock button on the fob and got nothing.

I know you said you followed the instructions, but just in case:

or:

1. Close all vehicle doors.
2. Insert the key into the ignition.
3. Hold down the power UNLOCK button on the driver’s door panel continue to hold down until instructed to release in step 9.
4. Perform steps 5 through 8 in fairly rapid succession.
5. Turn the ignition switch to the ON position (as far as you can go without starting the engine).
6. Turn the ignition switch to the OFF position.
7. Turn the ignition switch to the ON position.
8. Turn the ignition switch to the OFF position.
9. Release the power unlock button on the door panel. The vehicle will lock and unlock the doors automatically.
10. Hold down the LOCK and UNLOCK buttons on the transmitter simultaneously until the door locks and unlocks. This step may take up to 30 seconds.
11. Repeat step 10 NOW for each additional transmitter (including any existing transmitters).
12. Turn the ignition switch to the ON position in order to exit the transmitter programming mode.
