Re: Keyless Entry Key Doesn't Work
Regarding the remote transmitter issue: Take the remote transmitter to your Toyota dealer. Ask them to test your transmitter with their hand-held RF detector. All Toyota dealers are required to have one of these devices. The RF detector will test the remote to see if it is indeed transmitting the proper RF out of the transmitter, and the strength of the RF signal. If there is no signal, the remote has failed (unfortunatly common), and the remote will need to be replaced and reprogrammed to the vehicle. I do this quite regularly, and rarely do I tell customers taht they need to spend 800 dollars for such a simple diagnosis/fix. The keyless system is very reliable. I rarely change the ECU for the keyless, unless somebody somehow gets the ECU wet, then it def needs replaced. Hope this helps.

Disconnecting the battery erases stored memory,after you connect the battery put the key in the ignition cylinder and turn the driver door switch on(open) and off (closed), on (open),the entry,exist function then becomes complete, and the return operation can be operated,
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
Hello: To resynchronize the keyless entry close all doors, key out of ignition. Hold lock and unlock buttons till the doors (all) lock then unlock. If the transmitter still doesn't work you have other problems. Go to auto zone they can check your transmitter to see if it is working.
The radio may have a theft lock activated....unlocking it may be a pain. As for the keyless entry (assuming it's factory), make sure you start with a new battery in the remote(s) and try the steps on this page: http://www.automotivehelper.com/topic146039.htm
The keyless entry is designed to work with the doors closed (closed - not locked). If the door ajar sensor thinks the door is open the keyless entry is disabled. When you manually lock the door it might tighten the door just enough to activate the keyless entry. I would try slamming all the doors closed and then see if the keyless entry works. If it still wont work have the wiring checked on the front door lock.
