I have all the equipment for keyless entry...the keyless receiver and the body control module. however i cant get the bcm to recognize the keyless receiver. therefore, i cant get into programming mode to program the keyless entry fob. Anyone have any suggestions how to fix this problem?

Remote Function Actuator. key fob operates this

Do they work with the key fob, do you have one of those? They lock when put into gear an unlock when put into park because the BCM - body control module does that .

Door Lock System Components
The power door lock system consists of the following components:
• Driver door lock switch
• Front Passenger door lock switch
• Body Control Module (BCM)
• Relays: Driver Door Unlock -- on vehicles with RFA, Door Unlock, and Door Lock
• Door Lock fuse 15A
Door Lock System Controls
The power door lock system can be controlled by any of the following:
• A power door lock switch activation
• A keyless entry command -- if equipped with keyless entry


Driver and Passenger Door Lock Operation
When any of the door lock switches is pressed to the lock position, the BCM door lock/unlock signal circuit changes from an idle voltage of ~3.4 volts to 0.0 volts generating a lock command. The BCM then applies battery positive voltage to the Door Lock Relay, which in turn applies battery positive voltage to the Door Lock Actuator lock circuit of all the Door Lock Actuators. Since the Door Lock Actuator unlock circuits are held to ground through the resting Door Unlock Relay(s), the actuators execute the lock command, locking the doors.
The lock function can also be accomplished by the BCM having received a keyless entry door lock command, if the vehicle is equipped with keyless entry.


Driver and Passenger Door Unlock Operation

When any of the door lock switches is pressed to the unlock position, the BCM door lock/unlock signal circuit changes from an idle voltage of ~3.4 volts to ~1.7 volts generating an unlock command. The BCM then applies battery positive voltage to the Door Unlock Relay and the Driver Door Unlock Relay when equipped with keyless entry, the relay(s) in turn apply battery positive voltage to the Door Lock Actuator unlock circuit of all the Door Lock Actuators. Since the Door Lock Actuator lock circuits are held to ground through the resting Door Lock Relay, the actuators execute the unlock command, unlocking the doors.
The unlock function can also be accomplished by the BCM having received a keyless entry door unlock command, if the vehicle is equipped with keyless entry. Keyless entry personalization allows the driver door to be unlocked individually before unlocking the passenger doors. When this feature is active, the BCM will require a repeated unlock command to unlock the passenger doors.


Automatic Door Lock/Unlock
The automatic door lock/unlock function is a Vehicle Personalization feature with the following four programmable modes of operation:
The automatic door lock feature is disabled.
All of the doors lock when the vehicle is shifted out of Park with the ignition ON.
All of the doors lock when the vehicle is shifted out of Park with the ignition ON, and all of the doors Unlock when the vehicle is shifted into Park.
All of the doors lock when the vehicle is shifted out of Park with the ignition ON, and only the driver door Unlocks when the vehicle is shifted into Park.
For information on programming the automatic door locks, refer to Vehicle Personalization in Personalization.

According to GM there are 3 components in the RCDLR or RKE remote keyless entry system. My key fobs with new batteries only work standing right next to the car. The range of the key fob dropped at that the same time my TPMS tire pressure monitoring system repair warning came on my dashboard. The problem is that there are 4 different components on the 2015 Malibu. I will provide the GM part numbers for these, if you please tell me where they are and also how to replace them: #13583559 Remote Control Door Lock Receiver #13502554 Antenna #13502551 Ignition Lock Key Transmitter Antenna #13502549 Low Frequency Console Antenna

Probably not a whole lot your going to be able to do ,Unless you have a factory or some other professional type scan tool to check for DTC'S - diagnostic trouble code's , an have service repair info for power locks for your car . Computer controlled (BCM) - body control module .
Door Lock System Components
The Power Door Lock System consists of the following components:
• Body control module (BCM)
• Driver door lock switch
• Front passenger door lock switch
• Reversible door lock actuator in each of the doors
• IBCM (PWR) 15-amp fuse
• Driver door cylinder switch, if equipped

Door Lock System Controls
The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following:
• A door lock switch lock or unlock actuation
• A keyless entry transmitter actuation
• An automatic door lock or unlock actuation
• A last door closed locking (LDCL) actuation
If the driver door cylinder switch feature of the vehicle is functional, the locks may also be operated by a driver door cylinder switch lock or unlock activation


If the driver door cylinder switch feature of the vehicle is functional, the locks may also be operated by a driver door cylinder switch lock or unlock activation
Power Door Lock Switch Operation
Each door lock switch is wired to the body control module (BCM) through a separate door lock/unlock signal circuit. While these circuits are separated between the BCM and respective door lock switch, they are connected into a single circuit within the BCM. The BCM supplies voltage through the door lock/unlock signal circuits to each door lock switch. When either door lock switch is operated, this supply voltage is pulled to ground, providing the BCM with the required lock or unlock signal. In order for the BCM to distinguish between a lock and unlock signal, the lock switch contains two separate paths for this voltage to flow to the same body ground. When the switch is operated to the unlock position, the supply voltage flows to ground through a 1.5 K? resistor. When the switch is operated to the lock position, the supply voltage flows to ground through a different part of the switch circuit, which has no resistor. The BCM then interprets the flow of voltage as a lock or unlock request and powers the door lock actuators to the appropriate lock or unlock position.
Power Door Lock Actuators
The body control module (BCM) powers the reversible door lock actuators by providing battery positive voltage and ground to the appropriate lock and unlock control circuits of the actuators. The Lock control circuits of the driver and passenger door lock actuators are all connected together, however, the Unlock control circuits are connected in a slightly different way. While the unlock control circuits for the passenger door lock actuators are connected together, the driver door lock actuator has a separate unlock control circuit. The system is designed this way so that the keyless entry transmitter may be used to unlock only the driver door. Despite this difference, all of the lock actuators perform much the same way. When the door lock actuators are not active, all actuator Lock and Unlock control circuits are at ground potential within the BCM. Transitioning of the lock actuators to the lock or unlocked position depends upon which control circuits receive voltage and which control circuits receive ground.
• If the BCM is commanding the door lock actuators to Lock, it momentarily switches the lock control circuits to voltage. Since the unlock control circuits are at ground potential within the BCM, the actuators transition to the Lock position.
• If the BCM is commanding all door lock actuators to Unlock, it momentarily switches the unlock control circuits for both the driver and passenger door lock actuators to voltage. Since the lock control circuits are at ground potential within the BCM, all lock actuators transition to the Unlock position.
• If the BCM is commanding only the driver door lock actuator to Unlock, it momentarily switches only the driver door actuator unlock control circuit to voltage. Since the lock control circuit is at ground potential within the BCM, the actuator transitions to the Unlock position.
Power Door Lock and Unlock Operation w/Keyless Entry Transmitter
The keyless entry transmitter may be used to unlock only the driver door. When the unlock button of the keyless entry transmitter is pressed once, the body control module (BCM) receives the unlock request from the remote control door lock receiver (RCDLR). The BCM interprets this single press as an unlock driver door request and responds by switching only the driver door lock actuator unlock control circuit to voltage. With the lock actuator lock control circuit for the driver door at ground potential within the BCM, the driver door lock actuator transitions to Unlock.
If the unlock button of the keyless entry transmitter is pressed a second time within three seconds of the first press, the BCM interprets this second press as a request to unlock the passenger doors and responds by switching the passenger door unlock control circuits to voltage. With the lock actuator lock control circuits at ground potential within the BCM, the passenger door locks transition to Unlock.
To lock all doors with the keyless entry transmitter, a single press of the transmitter lock button is all that is ever needed. The BCM receives the lock doors request from the RCDLR and responds by switching all lock actuator lock control circuits to battery voltage. With the actuator unlock control circuits at ground within the BCM, all actuators transition to Lock.

Circuit Description
The remote control door lock receiver (RCDLR) communicates with the body control module (BCM) through the keyless entry serial data circuit.
When any button on the keyless entry transmitter is pressed, the transmitter sends a signal to the RCDLR.
The RCDLR sends either a lock or unlock request to the BCM, depending on which button is pressed on the transmitter.
The BCM receives the message and performs the appropriate function.

None of the door power lock's work ? Not from any switch ? F32 - 15 amp fuse location - body control module (BCM) . Probably not a fuse issue , door locks are controlled by the BCM controlling relay's located inside the BCM . This relay's are PCB - printed circuit board relay's , non serviceable . Your best bet , take it to a qualified repair shop .

Power Locks
The Body Control Module (BCM) monitors the door lock control switches. When the BCM receives an unlock/lock command from either door lock control switch, the BCM energizes a relay (internal to the BCM ) to supply the correct power and grounds for the door lock actuators.

Remote Keyless Entry (RKE)
The Remote Keyless Entry (RKE) feature is controlled by BCM . The BCM receives the RKE inputs from the Tire Pressure Monitor (TPM) module over the Medium Speed Controller Area Network (MS-CAN) . When any RKE transmitter button is pressed, the signal is received by the TPM module internal antenna. The TPM module then filters the RKE signal received to make sure it is a programmed transmitter. If the signal received is from a programmed transmitter, the TPM module sends the RKE command to the BCMover the MS-CAN . The BCM then interprets the RKE command and activates the corresponding output.
The BCM requests the illuminated entry feature to turn the interior lamps on when an unlock command is received. If a lock command is received, the illuminated entry feature turns off. The BCM then supplies voltage to the appropriate door lock actuator(s) to lock or unlock the doors. The RKE transmitter can also be used to activate the panic alarm. On vehicles with memory, the RKE transmitter also causes the BCM to send a MS-CAN message to the Driver Seat Module (DSM) to activate all memory features to the positions associated with the RKE transmitter being used.

Remote control door lock receiver (RCDLR)

The remote control door lock receiver (RCDLR) is a multifunction module that operates both the keyless entry system as well as the TPM system. When an RF message is received from a keyless entry transmitter, the RCDLR interprets this signal and will request via serial data that the body control module (BCM) perform the specific function, i.e. door lock, door unlock, or vehicle locate.

Door Lock System Components
The power door lock system consists of the following components:
• Driver door lock switch--Uses a single signal wire for both lock and unlock switch activations
• Front passenger door lock switch--Uses a single signal wire for both lock and unlock switch activations
• Body control module (BCM)--Class 2 module which requires programming when replaced
• Reversible door lock actuators in each of the doors
• Body control module PWR 15A fuse--Located in the body control module fuse panel, supplies power for the door lock system

Door Lock and Unlock Operation
The BCM PWR fuse supplies battery positive voltage to the BCM for the door lock system.
The BCM supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position, the reference voltage is taken directly to ground and the BCM senses 0.0 volts on the signal circuit. If a door lock switch is placed in the unlock position, the reference voltage is taken to ground through a 1.5K ohm resistor that is internal to the door lock switches and senses approximately 2.9 volts on the signal circuit. This is how the BCM determines what portion of the door lock switch was activated.
The BCM, upon receipt of a door lock switch lock or unlock signal, will switch the appropriate door lock actuator control circuits to battery positive voltage. The opposing side of the door lock actuators are connected to ground internally within the BCM through the other door lock actuator control circuit and the doors will lock or unlock appropriately.
Vehicles without keyless entry have two internal drivers in the BCM to control the door lock actuators. All door lock and all door unlock. Vehicles equipped with keyless entry have three internal drivers in the BCM. Driver door unlock, passenger door unlock and all door lock. This is done to isolate the driver door lock actuator so it can be unlocked by itself using the keyless entry transmitter.

Remote Control Door Lock Receiver (RCDLR)
The remote control door lock receiver (RCDLR) is a multifunction module that operates both the keyless entry system as well as the tire pressure monitoring (TPM) system. When an RF message is received from a keyless entry transmitter, the RCDLR interprets this signal and will request via serial data that the body control module (BCM) perform the specific function, i.e. door lock, door unlock, or vehicle locate. The RCDLR also sends messages out to the 2 Way Advanced Remote Start transmitter.
