Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi, glad to be of help. To do a 10 minute relearn you need a scan tool. Try a 30 minute relearn. This should fix your problem. Make sure battery is fully charged before beginning.
P1630: THEFT DETERRENT PASSWORDLEARN MODE
This code will set if the PCMremains in theft deterrent password XXXXX mode for more than 2 seconds. The PCMwill not light the Check Engine/Service Engine Soon light. It will store theconditions present when the code set. This code can be cleared by a scan tool.

GMVehicle Theft Deterrent (VTD) Relearn Procedures
Passlock III Relearn Procedure
30-Minute Relearn Procedure
Use this procedure after replacing any of the following components:
The PASS-Key III plus keys
The theft deterrent module (TDM)
The powertrain control module (PCM)
This procedure is not available on vehicles equipped with EXPORT configured TDMs.
When performing the 30-minute relearn procedure, all previously learned keys will be erased from the TDM memory. Additional keys may be learned after performing the relearn procedure.
When replacing a TDM with a GM SPO Replacement Part, ensure the procedure to setup a new TDM is performed prior to the 30-Minute Relearn Procedure.
1. With a master vehicle key, turn ON the ignition, with the engine OFF.
2. Observe the security indicator. After approximately 10 minutes, the telltale will turn OFF.
3. Turn OFF the ignition, and wait 5 seconds.
4. Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes.
5. ignition OFF before attempting to start the vehicle.
6. With a master vehicle key, start the vehicle. The vehicle has now learned the key transponder information and/or the ECM has now learned the fuel continue password.
7. If additional keys are required to be learned, continue to step 7.
8. With a previously learned master key, turn ON the ignition, with the engine OFF.
9. Turn OFF the ignition and remove the key.
10. Within 10 seconds insert the key to be learned. Turn ON the ignition with the engine OFF. The vehicle has now learned the new key.
Passlock III system uses a standard ignition key to rotate a specially coded ignition switch.
GM - three security systems currently in use: Pass-Key III (PK3) (transponder based)
system by Megamos, PASS-KEY II (VATS - key mounted resistor) and Passlock which uses a standard key.
PASSLOCK-how it works
The Passlock system is designed to prevent vehicle operation if the key is not used to start the vehicle. The key, which does not contain a resistor will turn the Passlock lock cylinder. The Passlock lock cylinder will relay a resistance code to the instrument panel cluster (IPC). It does this by rotating a magnet past a stationary hall effect sensor, creating a resistance code. At this point the IPC will determine if the resistance code is correct and within an acceptable time frame. If the code is correct, the IPC will send a coded password XXXXX the powertrain control module (PCM). If the PCM receives the correct password, it will allow the fuel injectors to operate normally and the vehicle will start and run normally. If the correct resistance code from the lock cylinder is not received within the acceptable time frame, the vehicle will gointo a short tamper mode during which the theft deterrent system will not allow the vehicle to operate for approximately 4 seconds. When this occurs, the security indicator will flash. After three consecutive failed tries, the system will enter into a long tamper mode. In this mode, the fuel injectors will be disabled for approximately 10 minutes, and the security indicator will be flashing. Please note that in any of the tamper modes, the vehicle may start, but it will quickly stall.
The Passlock system is designed to prevent vehicle theft even if any of the theft deterrent parts are replaced. Passlock eliminates the need for the key mounted resistor. Parts that can no longer be replaced without the possibility of the system going into a tamper mode and prevent starting are: the lock cylinder, the instrument panel cluster (IPC), and the powertrain control module (PCM).
In order to initiate the relearn:
1. Hook up your scan tool to erase any of the passlock/vehicle theft deterrent trouble codes. If there are any other codes, note them before you erase them, so you may address them after the relearn has been completed.
2. With the ignition key in the "On" position from the code-clearing step, attempt to start the vehicle. At this point, if the vehicle starts, and the security light has not illuminated, a relearn is not necessary, and you're done. If the vehicle starts and stalls, leave the key in the "Run" position and wait for the "Security" light to turn off. This will take approximately 11 minutes. At any time during this relearn, the light may flash or be on steady. If the ignition switch is turned off at any time during this relearn cycle that the security light is illuminated, the entire cycle must be restarted from the beginning. For most cars, one cycle will be sufficient for the relearn. If the vehicle will not start after the first cycle, then continue the process from step #3 to the end. Most trucks will require that you continue from step #3 to the end.
3. When the light turns off, turn the ignition switch to the "Off" position for approximately ten seconds.
4. Next, repeat steps 2 and 3 two more times for a total of three cycles. After the third time, the new code will be relearned on the next start attempt when the ignition switch is rotated from the "Off" position.
5. From the "Off" position, start the vehicle, observing the security light. If the vehiclestarts and runs normally, and the security light is off, the relearn is complete. If the vehicle does not start, check for trouble codes before proceeding further.
charged battery before and doing relearn. also performed the 30 min relearn procedure several times. theft light flashes about 4 times and stays on steady after the start and stall.
Did you load test the battery and clean connections on both sides of the bolts that screw into the battery? Does your scanner have bi-directional function such as a Tech2 and can access the BCM? Are there any other codes? What scanner are you using? Check all fuses and try swapping out or replacing the IGN relay next to cooling fan relays. What is your battery voltage? Was any other parts replaced such as BCM, instrument panel or others? What work has been done recently before and after the problem occured?
You may have the wrong key. They made two types for 2005. When you got the key from the dealer did you give them the complete vin number and option codes in glove box? Do you have a circle+ on your key? Is the first digit of your vin a 1 or 4 or 2 or 3? Is there an option code an AP3 listed in glove box or trunk? If your vin begins with 2 or 3 you may need a second key to program.

TSB Number & Issue Date TSB Title10-00-89-010C JUL 13 Locks - Key Code Security Rules, Applications (Canada)
will ck on vin in the am. customer pickedup key at dealer. thanks for the insight. what procedure is necessary if the vin reads 2 or 3?
no key fobs.how would the dealer program masterkey w/tech 2 -passthru or by some other method?
I never worked in the parts department to see how they do it but if you lost all keys, you need a master key cut & programmed to your vehicle before doing a key relearn. See this link: http://www.gminsidenews.com/forums/f53/if-you-need-get-keys-cut-code-15497/ .
You will need proof of ownership as well as Vin to get a master key. By master key they mean an original. You can program other keys after you have this master key.
http://www.gminsidenews.com/forums/f53/programming-new-master-pk3-key-canadian-vehicle-87131/This is the GM procedure... 1. Cut the new key using the mechanical key code for the vehicle. 2. Prepare the Techline terminal (and scan tool if needed) and connect to the vehicle. 3. Insert the new key in the ignition. 4. Turn the ignition switch to the ON position. 5. Download the security code from the T50/T60 scan tool. 6. The security indicator will flash once per second. Leave the key ON in this state for 10 minutes. 7. Turn the ignition switch to the OFF position. 8. Turn the ignition switch to the ON position. 9. The security indicator will illuminate for 2 seconds and the new key is learned. Disconnect the T50/T60 scan tool.You need a GM scanner to program a new master. Sorry, this is a dealer only project.
PASS-Key® III OperationYour vehicle is equipped with the PASS-Key® III (Personalized AutomotiveSecurity System) theft-deterrent system. PASS-Key® III is a passive theftdeterrent system. The system is automatically armed when the key is removed from the ignition. You do not have to manually arm or disarm the system. The security light will come on if there is a problem with arming or disarmingthe theft-deterrent system.When the PASS-Key® III system senses that someone is using the wrong key, itshuts down the vehicle's starter and fuel systems. The starter will not workand fuel will stop being delivered to the engine. Anyone using atrial-and-error method to start the vehicle will be discouraged because of thehigh number of electrical key codes.If the engine does not start and the security message comes on, there may be aproblem 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, tryanother 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 befaulty. 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 ofa new or replacement key. Up to 10 keys may be programmed for the vehicle. Thisprocedure is for learning additional keys only. If all the currently programmedkeys are lost or do not operate, you must see your dealer/retailer or alocksmith who can service PASS-Key® III to have keys made and programmed to thesystem.See your dealer/retailer or a locksmith who can service PASS-Key® III to get anew key blank that is cut exactly as the ignition key that operates the system.To program the new key:Verify the new key has PK3 stamped on it. Insert the original, already programmed key into the ignition lock cylinder andstart the engine. If the engine will not start, see your dealer/retailer forservice. 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.Insert the key to be programmed and turn it to ON/RUN within 10 seconds ofremoving the previous key. The security message will turn off once the key has been programmed. It may notbe apparent that the security message went on due to how quickly the key isprogrammed.Repeat Steps 1 through 4 if additional keys are to be programmed. If you are ever driving and the security message comes on and stays on, youwill be able to restart your engine if you turn it off. Your PASS-Key® III system,however, is not working properly and must be serviced by your dealer/retailer.Your vehicle is not protected by the PASS-Key® III system at this time.If you lose or damage a PASS-Key® III key, see your dealer/retailer or alocksmith who can service PASS-Key® III to have a new key made.Do not leave the key or device that disarms or deactivates the theft deterrentsystem in the vehicle.
vin begins with 1. key has a plus with a circle around.
unit does have ap3 option according to vin.
ck unit w/tech 2 , after attempting to program several times. codes are B3031-B3055-p1626.
The problem is, it is not detecting a key which leeds me to believe you may have the wrong key for your vehicle or it is not a master key. A Vin that begins with 1 means it was made in USA. A Vin that begins with 2 means it was made in Canada and two master keys are required. Since your Vin begins in 1, you only need one master key, but you need the correct one. The solution would be to take vehicle to dealer and have them program a new master key or have a locksmith who is capable to program your vehicle come out to you.
B3031: BCM IS IN LEARN MODE BUT DOES NOT SEE A VALID PASSLOCKTM SENSOR CODEA new BCM is programmed to accept the first voltage value it sees from the sensor, providing that the value is within limits. The BCM will set this code if it is in learn mode but does not see a valid sensor voltage (yellow wire).The BCM will light the SECURITY light steady.
Once the BCM detects a valid voltage value from the sensor, the B3031 changes to history code.
GM OBD Error Code Details for B3055
Key Not Present
P1626: LOSS OF THE STATE OF HEALTH
The PCM will set this code if the engine is running and the PCM detects aloss of the "state of health" serial data message from the IPC/BCM theftdeterrent system.
The PCM will NOT light the Check Engine/Service Engine Soon light. It willstore the conditions present when the code was set to inform the technician.The code will self clear if the PCM sees 40 consecutive starts without anothermalfunction.
AP3 is what the RPO code became after the dealer installed the accessory remote start. AP3 is what AP8 becomes with the upgrade kit. AP3 does not mean advanced remote start, just normal remote start.See:
AP3 CODE: = You need this remote GM/L: Part#: 22733524
w/ remote start option.
took unit to dealer. they attempted to program w/ gm equip. unit failed to program and the codes I sent back are the codes set after the attempt. I ask the dealer about the master key and they have never heard of this. I was a dealer tech for 10yrs. have been out of dealership for 4yrs. my key has the plus sign w/circle around in. how can we get or make a master key for this unit or what key blank should be used? sorry for this problem. this is the first one, that caused such a rukus.
If you took it to the dealer and they couldn't do it, I don't know what to tell you.
Did they look up your key according to Vin and options codes?

What I do know is it is not recognizing your key. Perhaps the key they gave you is defective. It sounds like you have the right key.
Here is the 2005 Malibu owners manual:
2005 Chevrolet Malibu Owner Manual - GMPP
Here are all the service bulletins on your car:
Your key should look like this:
When a new vehicle is delivered, the key has a bar-coded key tag. This tag may be removed by your dealer before it is delivered.
Each tag has a key code on it that tells your dealer or a qualified locksmith how to make extra keys. Keep the tag in a safe place. If you lose your keys, you’ll be able
to have one made easily using this tag. If you need a new key, go to your dealer for the correct key code.
I will opt out and see if any other expert can help you.
