ignition switch issue
I replaced the ignition cylinder and had it re keyed. Also replaced the housing. Hooked everything back up. Put the switch to acc. Everything works. Turn the key to turn on motor.
Nothing. Car just power downs. I hooked it up to a battery charger/power jumper. Still just powers down. Could the hypertech have anything to do with it? Any suggestions?

Hi Bblackstone,
I hope that one of our expert Tech Member can assist.
Did you re-flash your computer ?
Check out all your connections ?
Keep checking back on your thread & I hope that
a member can help you!

re flash
To re flash the computer. Would I have to erase the hypertech ?
Then to re flash the computer. Is that through the stereo?

Sorry 
, I don't have a answer for you, but keep checking back to see `if a member has the right procedure for you to do with a hypertech (?)

To re flash the computer. Would I have to erase the hypertech ?YES, restore your original tune with your programmer.
Then to re flash the computer.This has to be done at a GM dealer... it is the new keys that have to be learned/ programed to the car/ security system. Is that through the stereo?

Here is some info you can try first before having to go to the dealer.

I had to replace a lock cylinder in my grand am (previous owner changed it out and the keys did not match and the dealer had a problem re-keying the non-oem replacement). It's the same ignition switch and cylinder as our montes.
Because the lock cylinder has a passlock chip on it, you need to follow the security relearn process you would use for a PCM swap.
Unfortunately I do not have those steps with me right now (but I know those are somewhere here on mcf).

Also when I had the cylinder re keyed. It was the original key that was used. So is there still a learning program needed?

Your car key has a code in it for the security/ anti-theft system: So if that is what is giving you grief then I posted a link to, How to reset/ re-learn it/ the code... to get you past that without going to the dealer.

I don't mean to frustrate you. My key does not have the chip in it.plus. I can't find the link you posted.

In this system, the vehicle theft
deterrent functions are provided by
the theft deterrent control module.
There is a transponder embedded in
the head of the key that becomes
energized by the exciter coils in the
ignition lock cylinder when the
ignition switch is turned on. The
energized transponder now transmits
a signal containing a unique value to
the theft deterrent control module. If
the module accepts this value, then
there is an additional communication
that takes place between the module
and the key. If the module and the
key agree, then the module sends the
fuel enable password to the PCM. If
the PCM recognizes the password,
then the vehicle starts and runs
normally.

The ignition key is a normal
looking key with no visible contacts
as in the Passkey or VATS systems.
The transponder is located in the key
head. The transponder value is fixed
and cannot be changed. These keys
are usually identified by the letters
PK3, or PK3+ stamped into the steel
body. A relearn will be necessary if
any of the following have been
replaced: any key, the theft deterrent
control module or the powertrain
control module (PCM).

However, the PCM must learn the
new fuel enable password from the
new module. If you are replacing a
PCM with a PCM that has been used
in another vehicle or has been
remanufactured, then a relearn must
be performed in order for the PCM to
learn the fuel enable password. Keep
in mind that when you perform a
relearn on this system, all previously
learned keys will be erased from the
theft deterrent control module’s
memory. Any additional keys may be
relearned immediately after the first
relearn has been performed by
inserting the additional key and
turning the ignition switch to the
“On” position within ten seconds of
removing the previously learned key.
