Testing would need to be done , scan tool hooked up checking DTC'S - diagnostic trouble codes . View data etc...
Keyless Entry System Description and Operation - Active
The keyless entry system is a vehicle entry device. The keyless entry system is used in conjunction with the door locks to unlock the vehicle. Keyless entry will lock/unlock a door or open 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. A low transmitter 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, such as gas stations that use pay-at-the-pump RF transponders, may also cause interference that could lead to a malfunction. Keyless entry allows you to operate the following features:
• Door lock/unlock
• Rear compartment lid release
• Illuminated entry lamps
• Panic alarm/Vehicle locator
• Remote vehicle start

Your best bet , take it to a qualified repair shop . Dealer

2008 HHR Remote Starter not working


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 .

2008 Volkswagen Jetta keyless entry & lock problems


If the system is not working even when you press the buttons on the door, then the problem is not with the remote control. I would first check if all the fuses are ok, if they are, I would check the wiring on the door to make sure there are no wires broken of chaffed. Focus first on getting the system working with the door buttons and after that is ok, the move on to the keyless system in case it still does not work. Hope this helps.

Battery went dead on car, car security system is in safe mode and want let car start, when you unlock the car alarm sounds and want do anything else, Battery has been replaced, can i reset the alarm if so...


Hello,

The new battery should have reactivated the alarm? If this is a keyless entry, than your original code should work?

If it doesn't than you need to call the dealer, or seervice provider for your alarm system there has to be a reset code, or a new one has to be provided?

I would try your normal code first! If it works, your good, if not, your going to be on the phone! No body but the place you purchased your vehicle from or the Alarm system provider can give you that answer!

Kind Regards!

My keyless entry system does not work. I replaced the battery,but it did'nt help. flbob72@aol.com


It may not be the battery, however, if the battery went bad, you must reset the system after replacing battery. Read the owner's manual for instructions on resetting or go to your local GM dealer.
