Hello. My name is XXXXX XXXXX I will be assisting you today.

Do you have a scan tool?

.

What have you tried so far?

Replaced cylinder and need to reprogram . Can you recommend a affordable scantily if it will work

Actually William there is likely a way to do it without (an expensive) scan tool. It takes about 30 minutes and you will want to keep a charger, (or jumper cables) on it to keep the battery from dying.
.

30-Minute Relearn Procedure
Use this procedure after replacing the following components:

  • The passkey III (PK3) keys
  • The theft deterrent control module
  • The PCM, see important above
  1. With a master passkey III key (Black), turn ON the ignition, with the engine OFF.

IMPORTANT: This procedure is not available on vehicles equipped with option code (Z49 or BAE).
If replacing a theft deterrent control module with an GM SPO Replacement Part, perform the procedure to setup a new theft deterrent control module prior to the 30-minute relearn procedure.

  1. Observe the Security telltale, after approximately 10 minutes the telltale will turn off.
  2. Turn OFF the ignition, and wait 5 seconds .
  3. Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes .
  4. With a master passkey III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password.
IMPORTANT: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

.



Let me know how that does, thanks

Hi Jerry, after 20mins telltale has not gone out. What is meant by master key. I am using key that came with new aftermarket cylinder.





The master key is black, (not gray like the valet key) and 20 minutes is too long, the light should have gone out. What was the original problem?

.
Did you have to drill it out?

Key not going into cylinder

Just removed old cylinder like any GM and replaced with new cylinder and key.
Not sure what might be going on in there, (the lock cylinder or passkey sensor)

I will opt out and open it back up. Please DON’T REPLY to this post as that will lock the question back to me, also DON’T RATE THE ANSWER yet, someone should be along shortly, I’m sure, thanks and sorry I wasn’t able to help with it.

Hi,

I’m a moderator for this topic. It seems the professional has left this conversation. This happens occasionally, and it's usually because the professional thinks that someone else might be a better match for your question. I've been working hard to find a new professional to assist you right away, but sometimes finding the right professional can take a little longer than expected.

I wonder whether you're OK with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.

Thank you!
