Are you saying the car won't lock with the key in the driver's door?
Does the Central locking pump work ok?
The test is to sit in the car with the doors closed and the ignition on and press the door central locking switch (located just in front of the driver's interior door handle).
If this fails, there's a problem with the pump - repair or replace (replacement will need coding/adapting).

If the door locks with the switch, but does not with the key (assuming key turns in the lock), it'll be a lock micro switch. I don't think these are replaceable on their own. You may attempt cleaning it, or replace the lock assembly.
Is there a key lock on the passenger side? Does that work? Odds are both failing are pretty remote...

Otherwise do as George says and try to get the remote working.
Does it only have one? They came with two and they're quite expensive to replace...

It needs to be adapted using dealer scan tool or if you know someone with VAGCOM.  Make sure you have all your remotes.  When performing this.

Keyless Entry System Description and Operation (with Accessory 2 Way Remote)
Keyless Entry System Description and Operation (without Accessory 2 Way remote)

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/liftgate 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
• 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

Your best bet , take it to a GM dealer .

in short your only options are a locksmith but the back window out and replace it later or let it run out of gas still in the morning call the dealership getting the VIN number of the vehicle and they can tell you the keyless entry cocode however I don't think that I help you because Fabian your battery will be dead because if I would have ran outta gas in the ignition switch would have been on all night and the battery will be dead in the morning

2005 Nissan Sentra, the keyless entry locks the doors but does not unlock them.


does your unlock button work in car? If it does, do you have another keyless entry key fob? If so does it work? If you just replaced the battery you can try removing battery and cleaning contacts within remote. I know some of the nissan altimas had the same issue and the only solution was a new key fob. Good Luck

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 .

Keyless remotes not working


Try reprogramming the remotes. Here are the instructions for the procedure. Hope it helps. Cobra!
Programming NOTE: All keyless entry remote transmitters (15K601) must be programmed at the same time.
NOTE: To program (or reprogram) the keyless entry remote transmitters into the RAP module, perform the following steps:
  1. Make sure that the anti-theft system is not armed or triggered.
  1. Turn the ignition switch (11572) from OFF to RUN eight times within ten seconds, ending in RUN. If the RAP module has successfully entered program mode, it will lock and then unlock all doors.
  1. Within 20 seconds, press any button on a keyless entry remote transmitter, and the doors will lock and then unlock to confirm that each keyless entry remote transmitter has been programmed. Repeat this step for each transmitter.
  1. If the door locks do not respond for any keyless entry remote transmitter, wait several seconds and press the button again. If the door locks still fail to respond, refer to Inspection and Verification.
  1. Turn the ignition switch to the OFF position, or wait up to 20 seconds after step 2, to exit program mode. If a keyless entry remote transmitter has been programmed (or reprogrammed), the RAP module will lock and unlock all doors one last time to confirm.

security module in the trunk ???? There is no security module in the trunk . What light's come on by them self ? Park lamps , headlamps , brake lamps ,turn signals etc.... The module for anti-theft is under the right hand side of the dash . The remote keyless entry module is located in the trunk. Is this the part you hear clicking in ?
Door Lock Control Processor, Electronic NOTE: The electronic door lock control system will not function when the ignition switch is in the RUN or ACC position.
The electronic door lock control processor:
  • is located on the LH side of the luggage compartment.
  • contains a radio receiver that receives a signal from the keyless entry remote transmitter (15K601) through electronic door lock control processor antenna, and sends the appropriate command to the power door locks, the horn relay, the indicator flasher, or the anti-theft warning system.
  • is equipped with a battery backup which holds the programmed code in memory in the event the vehicle battery is disconnected.

Intall Remote Keyless Entry System in an 02 Honda Accord


You got the Wrong Information! Go to Wal Mart and Purchase a "Bulldog Security Keyless Entry" System for your Car. It will cost you a Quarter of the Price and is Just asw Reliable as the Factory Unit! Got one on My Truck with Remote Start also and it works GREAT! Should cost about $50.00 Bucks or so.
