Question about liftmaster Chamberlain Garage Door Opener Transmitter 300MC

1 Answer

Cannot get any remote to operate the door opener. I've checked this w/ another remote which does work when used to operate another door. It appears I'm not able to reprogam the remote that came w/ the door opener (1/2 HP Chamberlain 1996 mfg'd date) per the directions on the power unit. This was initially noticed when the factory remote in the car rear view mirror was not working. Any thoughts

Typically the remote codes are stored on the controller board (called logic board). if the wall switch for your opener still works, but you are unable to reprogram the existing remotes that came with the unit (assuming of course you checked batteries in the remotes) then it is likely that the logic board has died. Given that the opener is 13 years old, this is not unexpected. New openers have a host of new features including advanced security, so it might be a good time to invest in a new one.

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 .

Intermittent remote trouble


Your wall control is hard wired and doesn't use the receiver portion of the logic board. The remotes do. Your receiver is going bad.
