Content Theft Deterrent (CTD) Description and Operation When armed, the content theft deterrent (CTD) system is designed to deter vehicle content theft by pulsing the horns and exterior lamps for approximately 30 seconds when an unauthorized vehicle entry is detected. However, the CTD system does not affect engine starting.
An unauthorized entry can be any of the following with the CTD system armed:
• When any door is opened without first being unlocked using the UNLOCK command from the keyless entry transmitter
• Unauthorized entry into the underhood area (if equipped)
• Unauthorized entry into the rear compartment
• After a battery reconnect, if the battery was disconnected with the CTD system armed
The components of the CTD system are:
• Body Control Module (BCM)
• Remote Control Door Lock Receiver (RCDLR)
• Security indicator
• Door ajar switches
• Rear compartment lid ajar switch
• Hood ajar switch (if equipped)

Arming the CTD System
Use the following procedure in order to arm the system:
Place the shift lever in P (park).
Turn OFF the ignition.
Open any door.
Important: The system is not armed if the doors are locked manually; the remote keyless entry transmitter must be used to arm the content theft deterrent (CTD) system.
Lock the doors using the LOCK button on the transmitter. The system is in standby mode and will not start the arming timer until all doors are closed.
The system will begin the arm sequence immediately after the last door is closed. If the keyless entry transmitter is used to arm the system after the vehicle doors are closed, the arm sequence will begin as soon as the LOCK command is received by the transmitter.
Locking the Vehicle Without Arming the CTD System
Locking the vehicle may be accomplished without arming the content theft deterrent (CTD) system. Use of the manual door locks or using the key to lock the doors will lock the vehicle, but will not arm the CTD system.
Disarming an Armed System/Silencing an Alarm
If system arming has been requested by the keyless entry transmitter, it must be disarmed.
Important: Using the power door unlock switch or manually unlocking the doors does not disable the content theft deterrent (CTD) arm mode. Also, disconnecting the battery or pulling fuses does not disable the arm mode, since the BCM stores the CTD mode status in memory.
• To disarm the CTD system in standby mode, perform one of the following:
- Press the UNLOCK button on the keyless entry transmitter.
- Insert a valid key into the ignition and switch to the ON position.
• To disarm the CTD system in the armed mode (non-event) or when activated (during an alarm event):
Press the UNLOCK button on the keyless entry transmitter.

Is this the alarm your talking about ?

Who replaced the headlamp bulb ? Take it back . Everything your having problems with are all controlled by the BCM - body control module . May have crossed wire's ,shorted etc....

As far as the sliding doors , pull the fuse's

STARTING DISABLED REMOVE KEY
Refer to Theft Systems Description and Operation in Theft Deterrent

STARTING DISABLED REMOVE KEY
The radio illuminates the STARTING DISABLED REMOVE KEY message when the VTD system has disabled the starting system. The radio receives a message from the theft deterrent control module via the serial data circuit requesting illumination.

Your best bet have it towed to a qualified repair shop .
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

The vehicle horns are activated under the following conditions:
?€¢
The horn switch is depressed.

?€¢
The body control module (BCM) commands the horns on. The BCM commands the horns on under either of the following conditions:

-
When the content theft deterrent system detects a vehicle intrusion. For further information, refer to Content Theft Deterrent (CTD) Description and Operation in Theft Deterrent.

-
When the panic button is depressed on the remote control door lock transmitter. For further information, refer to Keyless Entry System Description and Operation in Keyless Entry.

-
When the OnStar?® system is used to sound the horns, if equipped. For further information, refer to OnStar Description and Operation in Cellular Communications.

-
When the keyless entry system is used to lock the vehicle, a horn chirp may sound to notify the driver that the vehicle has been locked. The notification feature may be enabled or disabled through personalization. For further information, refer to Keyless Entry System Description and Operation in Keyless Entry

The anti theft is in the computer program. You may have to have it reflashed at the dealership.

You must take it to the dealer and explain your situation. You will need your VIN number and possibly other info. These radios match the vehicle they were installed in and they lock when they are removed from the original vehicle as a theft deterrent.

{: ) When armed, the content theft deterrent (CTD) system is designed to deter vehicle content theft by pulsing the horns and exterior lamps for approximately 30 seconds when an unauthorized vehicle entry is detected.

An unauthorized entry can be any of the following with the CTD system armed:
• When any door is opened without first being unlocked using the keyless entry transmitter • After a battery reconnect, if the battery was disconnected with the CTD system armed Disarming an Armed System/Silencing an Alarm
If system arming has been requested by the power door lock switch or the keyless entry transmitter, it must be disarmed.
Important: Using the power door unlock switch or manually unlocking the doors does not disable the content theft deterrent (CTD) arm mode. Also, disconnecting the battery or pulling fuses does not disable the arm mode, since the BCM stores the CTD mode status in memory.
• To disarm the CTD system in standby mode, perform one of the following: - Press the UNLOCK button on the keyless entry transmitter. - Insert a valid key into the ignition and switch to the ON position. • To disarm the CTD system in the armed mode (non-event) or when activated (during an alarm event): - Press the UNLOCK button on the keyless entry transmitter. - Insert a valid key into the ignition and switch to the ON position Locking the Vehicle Without Arming the CTD System Locking the vehicle may be accomplished without arming the content theft deterrent (CTD) system. Use of the manual door locks or using the key to lock the doors will lock the vehicle, but will not arm the CTD system.
