I installed a bulldog remote starter with keyless entry and the doors won't unlock or lock with remote, why?

The yellow wire at the ignition switch is not connected to the remote start system. Once it is connected to the accessory output of the remote start, it should work properly.

Is this an issue with all 2008 HHR remotes??? Highly doubtful , probably the vehicles keyless entry system . Taking the vehicle to a qualified repair shop an having the keyless entry system checked for DTC'S - diagnostic trouble code's . Do you know what a DTC is ?
The keyless entry system is a vehicle entry device. The keyless entry system is used in conjunction with the body control module (BCM) to remotely activate certain vehicle features. Keyless entry will lock/unlock the doors, or release the rear compartment lid when a corresponding button on the keyless entry transmitter is pressed. This is accomplished by the transmitter sending a radio frequency to the remote control door lock receiver (RCDLR). The RCDLR interprets the signal and activates the requested function via a serial data message to the BCM. A low transmitter or vehicle battery or radio frequency (RF) interference from aftermarket devices, such as 2-way radios, power inverters, computers, etc., may cause a system malfunction. High RF traffic areas may also cause interference that could lead to a malfunction. Keyless entry allows you to operate the following components:
• Door locks
• Liftgate lock
• Remote rear doors (Panel only)
• Vehicle locator/panic alarm
• Illuminated entry lamps
• Remote vehicle start
The keyless entry system has the following components:
• Keyless entry transmitters
• Keyless entry antenna
• 2 Way Advanced Remote Start RCDLR
• BCM

Guessing will not fix this .

Keyless Entry
The keyless entry system consists of the following:

• smart entry control(SEC)/timer module
• keyless entry remote transmitters
• power door lock actuators
• body side door power door lock actuator
• liftgate actuator
• power door lock switches
• door ajar switches
• Principles of Operation
  All doors can be locked at once by turning the door key lock switch to the locked position. An individual door can be unlocked by moving the door key lock switch to the unlocked position and turning it again within five seconds; all the doors (including the liftgate) will unlock.
  The smart lock system is designed to keep the driver from locking his keys in the car. It will lock and then unlock all the doors if the smart entry control(SEC)/timer module detects the following conditions:
  
  • The ignition key still in the ignition.
  • A front door is open.
  • A door lock switch has been pushed to the lock position.
  The panic feature has a duration of 30 seconds from the last time the PANIC button is pressed. When locking the doors from the remote transmitter, the horn chirp/lamp flash feature can be disabled or enabled by holding the LOCK and UNLOCK buttons for two seconds. The hazards will flash three times to confirm that the feature has be enabled or disabled.

The control module probably see's an input that shouldn't be there . lock Switch , door ajar etc... Don't think it has anything to do with the remote . Some part stores have a tester to see if signal from the remote is working . Or the dealer ! Take it an see if your remote is sending a signal without you pressing any buttons .
If it is you need a new one .

i dont think that your 04 camry has a remote start unless it is an aftermarket installed keyless entry
and remote start. my 03 toyota remote has lock,unlock,trunk onfront of remote and panic button on
the back that is red.

if you have the manual at hand, put key in ignition and turn to the on and off position fast as you can and then push button. it should not rrespond because thats resets the alarm, follow manual on how to reprogram! hopes it helps out.
