Without a key with anti-theft transponder inside your not starting anything . Your best bet call mobile lock smith . Anti-theft system ,software programmed into all module's involved in starting the vehicle .
The vehicle theft deterrent (VTD) system functions are provided by the theft deterrent control module. The VTD system prevents vehicle operation if a learned Passkey III (PK3) ignition key is not used to start the vehicle. Vehicles with steering column mounted ignition switches have the exciter integral with the theft deterrent control module which is located within the steering column. Vehicles with instrument panel mounted ignition switches have exciter modules separate from the theft deterrent control module with the vehicle wiring harness connecting the two. The PK3 key has a transponder embedded in the plastic head of the key. The exciter is an antenna which is made up of wire coils which surround the ignition lock cylinder. The PCM enables engine starting when it receives a learned fuel enable signal from the theft deterrent control module. The components of the VTD system are as follows:

Where is the starter relay on a 1998 Monte Carlo located


It's not called a starter relay , it's theft deterrent relay and it's controlled by the theft deterrent module.
When the ignition switch is moved to the START position (and the theft deterrent module recognizes the key code), battery voltage is applied to starter solenoid (through the theft deterrent relay). Both solenoid windings are energized. The circuit through the pull-in winding is completed to ground through the starter motor. The windings work together magnetically to pull in and hold the plunger, which moves the shift lever. This action causes the starter drive assembly to rotate as it engages with the flywheel ring gear on the engine. At the same time, the plunger closes the solenoid switch contacts in the starter solenoid. Full battery voltage is applied directly to the starter motor, which cranks the engine.

How to reset Theft Deterrent fuel enable signal


have you put obd11 scanner on it to find error code.
DTC P1626 Theft Deterrent Fuel Enable Signal Lost
Circuit Description
The Vehicle Theft Deterrent (VTD) system is incorporated within the body control module (BCM). The powertrain control module(PCM) monitors the state of health serial data message from the Theft Deterrent system to ensure that the PCM to BCM communications is established. If the PCM detects a loss of the state of health message while the engine is running, DTC P1626 will set. DTC P1626 can cause a no-start condition or normal operation depending on when the loss of Theft Deterrent system communication was detected. The engine will continue to start and run if the condition that set DTC P1626 occurred after the PCM received a valid theft deterrent password from the BCM and already allowed fuel during the ignition cycle. The engine will start and immediately stall if the condition that set DTC P1626 occurred before the PCM received a valid theft deterrent password. With this condition present, the PCM will inhibit fuel delivery and disable the starter until a valid theft deterrent password is detected. Refer to Content Theft Deterrent (CTD) Circuit Description .

Conditions for Running the DTC
The Theft Deterrent system has allowed fuel delivery.
Conditions for Setting the DTC
The PCM has detected a loss of the state of health serial data message from the Theft Deterrent system.

Action Taken When the DTC Sets
The PCM stores conditions which were present when the DTC set as Failure Records only. This information will not be stored as Freeze Frame Records.

Conditions for Clearing the MIL/DTC
The DTC becomes history when the conditions for setting the DTC are no longer present.
The history DTC clears after 40 malfunction free warm-up cycles.
The PCM receives a clear code command from the scan tool.
Diagnostic Aids,
An intermittent may be caused by:

• A poor connection

• Rubbed through wire insulation

• A wire broken inside the insulation

Check for the following conditions:, • Intermittent short circuit on the serial data circuit -- Refer to Data Link Communications Operation in Data Link Communications. Be sure to check all related wiring for an intermittent short to ground or short to voltage.

• Poor connection -- Inspect the wiring harness for damage. Check for an intermittent short or open circuit in the wiring harness related to the BCM, including the ignition, battery feed, ground, and Serial Data circuits.

How am i supposed to get ride off the Service theft system?


It's hard to fix something if you don't know how it works ! Fixed ignition ? What did you fix or change ?
SERVICE THEFT SYSTEM
Security: Refer to Theft Systems Description and Operation in Theft Deterrent
You need to have it checked for trouble codes .
The theft deterrent system on this vehicle is comprised of two separate systems, the vehicle theft deterrent (VTD) system and the content theft deterrent (CTD) system. The VTD system prevents drive away theft by keeping the vehicle from starting. The CTD system is the vehicle alarm system which discourages unauthorized entry into the vehicle. These systems are described and diagnosed separately within this section.
Theft System Indicators
SECURITY The instrument panel cluster (IPC) illuminates the SECURITY indicator as determined by the vehicle theft deterrent (VTD) system and the content theft deterrent (CTD) system. The IPC receives a message from the theft deterrent control module or the rear integration module (RIM) via the serial data circuit requesting illumination.
?€¢
The VTD system requests the IPC to illuminate the indicator only when the ignition switch is ON. The VTD system uses the indicator as a malfunction indicator. For specific VTD condition that will illuminate the security indicator, refer to
Vehicle Theft Deterrent (VTD) Description and Operation .


?€¢
The CTD system requests the IPC to illuminate the indicator only when the ignition switch is OFF. The CTD system uses the indicator in order to identify system status. For specific CTD condition that will illuminate the security indicator, refer to Content Theft Deterrent (CTD) Description and Operation .


?€¢
The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
SERVICE THEFT SYSTEM The radio illuminates the SERVICE THEFT SYSTEM message when the VTD system detects a failure. The radio receives a message from the theft deterrent control module via the serial data circuit requesting illumination.
This is one you need to take to the dealer , unless you have a GM factory scan tool !

One is under the hood in the engine compartment an Rear Fuse Block
Left rear of the passenger compartment, under the rear seat ! There are a couple of fuse's , but they power up the ignition an the PCM ,so you can't pull those ! Beside that if the PCM does not get a fuel enable signal from the anti-theft module the vehicle won't start . You can't just disable thing's on this vehicle ! If you have security light on steady or flashing you need to take it to someone who has a diagnostic scan tool that can check DTC'S - diagnostic trouble codes ! A code reader can not access these type codes !
Vehicle Theft Deterrent (VTD)Circuit Description
(VTD) Theft Deterrent System Components
Ignition Key (Transponder) The ignition key for the (VTD) theft deterrent system is a typical ignition key with a transponder pellet located in the plastic end of the key. The ignition key transponder value is used to determine if a valid ignition key is being used to start the vehicle, there are approximately three trillion different transponder values available. This vehicle has two types of ignition keys.
?€¢
Master key (black plastic end) which can start the vehicle and lock/unlock all door locks, all storage compartments and the rear compartment lid lock.


?€¢
Valet key (gray plastic end) which can start the vehicle and unlock/lock all doors, but can not unlock/lock the storage compartments, or rear compartment lid lock.

Important: The transponder values are not readable and can not be serviced separately.
Theft Deterrent Module The theft deterrent module contains the software for controlling the VTD System. The theft deterrent module uses the following inputs and outputs to control the VTD system.
Inputs ?€¢
Battery voltage from the underhood fuse block PCM/BATT fuse, circuit 240 (ORN).


?€¢
Ignition start voltage from the ignition switch, circuit 1390 (WHT).


?€¢
Ground, circuit 450 (BLK).
Outputs Password exchange with the PCM (fuel enable), class 2 message circuit 1807 (PPL).
Powertrain Control Module (PCM) The PCM verifies that the passwords received from the theft deterrent module via the class 2 serial data line are valid. If a password is invalid the PCM disables the fuel delivery system. If the password is valid the PCM enables the fuel delivery system.
Starter Relay The starter relay is controlled by the PCM module via class 2 serial data (CKT 1807 PPL). If the theft deterrent module measures the correct transponder value, the PCM module switches the starter enable control (CKT 447 YEL) to ground. The relay is energized if the ignition switch is in the START position and the gear selector is in the PARK or NEUTRAL positions.

Security button to resetm pass key is located where?


your vehicle is equipped with Personal Automotive Security System (PASS-Key II(R)).
This security system is designed to prevent vehicle theft by disabling fuel system and starter unless an ignition key with a specific electrical resistance is used in the ignition key lock cylinder. PASS-Key II(R) system operates using sensing contacts, which are located in the ignition key lock cylinder. These contact a resistor pellet located in the ignition key. When lock is rotated, battery voltage is applied through appropriate fuse and resistor pellet to theft deterrent module (except Century), or body control module (Century). Pellet resistance is then compared with programmed value in the theft deterrent module or Body Control Module (BCM).
System components include ignition key, ignition key lock cylinder, theft deterrent module (except Century) or BCM (Century), theft deterrent relay and Powertrain Control Module (PCM). The PASS-Key II(R) system can also be supplied as a special equipment option on some vehicles

It will reset itself after about 10 minutes. You just have to wait until you hear a click and the pass key light goes off.
Be sure to clean the little metal strip on your key while you're waiting...

The theft deterrent module or the insturment cluster or the ECM is not seeing correct info.
The vehicle theft deterrent (VTD) system functions are provided by the theft deterrent control module. When an ignition key is inserted into the ignition lock cylinder and the ignition is switched ON, the transponder embedded in the head of the key is energized by the exciter coils surrounding the ignition lock cylinder. The energized transponder transmits a signal that contains its unique value, which is received by the theft deterrent control module. The theft deterrent control module then compares this value to a value stored in memory, learned key code. If the value is correct the theft deterrent control module sends a random generated number to the transponder, this is called a challenge. Both the transponder and the theft deterrent control module perform a calculation on the challenge, if the calculations match the theft deterrent control module sends the fuel continue password via the serial data circuit to the Engine control module (ECM). If either the transponders unique value or the calculation to the challenge is incorrect the theft deterrent control module will send the fuel disable password to the ECM via the serial data circuit. The components of the VTD system are as follows:
• Theft deterrent control module
• Engine control module (ECM)
• Ignition key (Transponder)
• Ignition lock cylinder
• Security indicator
