"Any new PASS-Key® III key must be programmed
before it will start your vehicle. See PASS-Key® III
on page 2-29for more information on programming
your new key
PAGE 2-30
When the PASS-Key® III system senses that someone
is using the wrong key, it shuts down the vehicle's
starter and fuel systems. The starter will not work and
fuel will stop being delivered to the engine. Anyone
using a trial-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
If the engine does not start and the security message
comes on, there may be a problem with your
theft-deterrent system. Turn the ignition off and try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. If the engine
still does not start with the other key, your vehicle needs
service. If your vehicle does start, the first key may be
faulty. See your dealer/retailer or a locksmith who
can service the PASS-Key® III to have a new key made.
It is possible for the PASS-Key® III decoder to learn the
transponder value of a new or replacement key. Up to
10 keys may be programmed for the vehicle. This
procedure is for learning additional keys only. If all the
currently programmed keys are lost or do not operate,
you must see your dealer/retailer or a locksmith who
can service PASS-Key® III to have keys made and
programmed to the system.
See your dealer/retailer or a locksmith who can service
PASS-Key® III to get a new key blank that is cut
exactly as the ignition key that operates the system.
To program the new key:
1. Verify the new key has PK3 stamped on it.
2. Insert the original, already programmed key into
the ignition lock cylinder and start the engine.
If the engine will not start, see your dealer/retailer
for service.
3. After the engine has started, turn the key to
LOCK/OFF and remove the key.
For vehicles first sold in Canada, repeat Step 2
with a different, already programmed, key before
proceeding to Step 4
4. Insert the key to be programmed and turn it to
ON/RUN within 10 seconds of removing the
previous key.
The security message will turn off once the key has
been programmed. It may not be apparent that
the security message went on due to how quickly
the key is programmed.
5. Repeat Steps 1 through 4 if additional keys are to
be programmed"

When a PCM (JTEC) and the SKIM are replaced
at the same time, perform the following steps in
order:
(1) Program the new PCM (JTEC).
(2) Program the new SKIM.
(3) Replace all ignition keys and program them to
the new SKIM.
PROGRAMMING THE PCM (JTEC)
The SKIS Secret Key is an ID code that is unique
to each SKIM. This code is programmed and stored
in the SKIM, the PCM, and the ignition key transponder
chip(s). When replacing the PCM, it is necessary
to program the secret key into the new PCM
using the DRBIIIt scan tool. Perform the following
steps to program the secret key into the PCM.
(1) Turn the ignition switch to the On position
(transmission in Park/Neutral).
(2) Use the DRBIIIt and select THEFT ALARM,
SKIM, then MISCELLANEOUS.
(3) Select PCM REPLACED (GAS ENGINE).
(4) Enter secured access mode by entering the
vehicle four-digit PIN.
(5) Select ENTER to update PCM VIN.
NOTE: If three attempts are made to enter secured
access mode using an incorrect PIN, secured
access mode will be locked out for one hour. To
exit this lockout mode, turn the ignition switch to
the ON position for one hour, then enter the correct
PIN. (Ensure all accessories are turned off. Also
monitor the battery state and connect a battery
charger if necessary).
(6) Press ENTER to transfer the secret key (the
SKIM will send the secret key to the PCM).

(7) Press PAGE BACK to get to the Select System
menu and select ENGINE, MISCELLANEOUS, and
SRI MEMORY CHECK.
(8) The DRBIIIt will ask, “Is odometer reading
between XX and XX?” Select the YES or NO button
on the DRBIIIt. If NO is selected, the DRBIIIt will
read, “Enter Odometer Reading (From I.P. odometer)”.
Enter the odometer reading from the instrument
cluster and press ENTER.
PROGRAMMING THE SKIM
(1) Turn the ignition switch to the On position
(transmission in Park/Neutral).
(2) Use the DRBIIIt and select THEFT ALARM,
SKIM, then MISCELLANEOUS.
(3) Select PCM REPLACED (GAS ENGINE).
(4) Program the vehicle four-digit PIN into SKIM.
(5) Select COUNTRY CODE and enter the correct
country.
NOTE: Be sure to enter the correct country code. If
the incorrect country code is programmed into
SKIM, it cannot be changed and the SKIM must be
replaced.
(6) Select YES to update VIN (the SKIM will learn
the VIN from the PCM).
(7) Press ENTER to transfer the secret key (the
PCM will send the secret key to the SKIM).
(8) Program ignition keys to the SKIM.
NOTE: If the PCM and the SKIM are replaced at the
same time, all vehicle ignition keys will need to be
replaced and programmed to the new SKIM.
PROGRAMMING IGNITION KEYS TO THE SKIM
(1) Turn the ignition switch to the On position
(transmission in Park/Neutral).
(2) Use the DRBIIIt and select THEFT ALARM,
SKIM, then MISCELLANEOUS.
(3) Select PROGRAM IGNITION KEY’S.
(4) Enter secured access mode by entering the
vehicle four-digit PIN.
NOTE: A maximum of eight keys can be learned to
each SKIM. Once a key is learned to a SKIM it (the
key) cannot be transferred to another vehicle.
(5) Obtain ignition keys to be programmed from
the customer (8 keys maximum).
(6) Using the DRBIIIt, erase all ignition keys by
selecting MISCELLANEOUS, and ERASE ALL CURRENT
IGN. KEYS.
(7) Program all of the ignition keys.
If ignition key programming is unsuccessful, the
DRBIIIt will display one of the following messages:
² Programming Not Attempted - The DRBIIIt
attempts to read the programmed key status and
there are no keys programmed into SKIM memory.
² Programming Key Failed (Possible Used
Key From Wrong Vehicle) - SKIM is unable to program
an ignition key transponder due to one of the
following:
² The ignition key transponder is faulty.
² The ignition key transponder is or has been
already programmed to another vehicle.
² 8 Keys Already Learned, Programming Not
Done - The SKIM transponder ID memory is full.
² Learned Key In Ignition - The ID for the ignition
key transponder currently in the ignition lock
cylinder is already programmed in SKIM memory.

You have either put the batteries in wrong or you have lost programming, see the dealer if you are 100% sure the new batteries where not installed incorrectly. What about the spare key???

He's trying to scam you to get out of having to replace a key they programmed incorrectly. The only other possibility is that the ignition switch itself is faulty since that is what sends the signal to the ECM that a proper key is installed. Since it works with the original key that is unlikely.

you have to get the key programed you need two original keys 1.) place original key in ignition turn to on position for 5 seconds 2. tack 1st key out and put secound key in the ignition turn key to on position for 10 seconds take key out place the new key in turn to on position for 10 secounds take out the key now try to start the car it should run if the the is programable

u must put a key to ignition and open a drive door 3 times and press and hold lock button

groan.....gunna need a bit more info. but i'll try. What portion of the ignition was ripped out? The tumbler + switch? If so, you might need to get the car's system resent to recognize that it has a new ignition put in. Sime vehicles have a theft prevention system in place to prevent the vehicle from running if its been hot wired. Your best bet would be to replace the damaged ignition components (You did not mention if you did or not). If it still doesn't work after you have replced all of the ignition components. You can try to reset the vehicle (doesn't work on all) disconnect negative battery terminal and go back into vehicle and press down the brake pedal for about 30 seconds then reconnect battery and try it....good luck, hope this helps
