Keyless entry has stopped working. Battery is replaced but still no remote operation of the doors or trunk.

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

The Lock's lock from the door switches ? If they do it's not a fuse problem . Which of these does your vehicle have ?
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 .

Use your key to unlock the door / trunk. If your car starts up; it might just be a connector and / or your battery in your remote. Try the simple / cheaper fix check by checking the connectors leading to the trunk release solenoid.

Probably the battery in the remote. Would check that first. Let me know if that works before getting deeper into it.

It sure sounds like a fuse. You can check for proper voltage at the hot wire of the actuator while you try to pop it. I think you are overlooking the fuse. Make sure the actuator has a good ground as well.

Your keyless entry system is going bad and you need a battery for your keyless entry system once you replace your battery with the new one thing should work properly

The keyless entry system is controlled by the (GEM) - generic electronic module .
Keyless Entry The electronic door lock system has two main components:

• generic electronic module (GEM)(14B204)
• keyless entry remote transmitter (15K601)
• NOTE: Battery power and ground must be remove before disconnecting the GEM connectors to avoid setting false codes.
  Power Locks Operation The power locks feature allows the customer to lock and unlock the doors via momentary switches located on the driver and passenger door. When the GEM detects a momentary press of the driver or passenger lock button, the GEM will supply power to the driver or passenger lock actuators for approximately 250 ms from relays internal to the GEM. When the GEM detects a momentary press of the driver or passenger unlock button, the GEM will supply power to the driver or passenger unlock actuators for approximately 250 ms from relays internal to the GEM.
  Remote Keyless Entry Door Locks Operation The remote entry feature allows the customer to unlock the driver door, unlock all doors, and lock all doors using a valid remote transmitter as long as the ignition switch is not in RUN or START. The driver door is unlocked whenever the GEM detects a valid remote transmitter unlock transmission. All the doors are unlocked when the GEM detects a second valid remote transmitter unlock transmission within three seconds of the first transmission. All the doors are locked when the GEM detects a valid remote transmitter lock transmission. If the GEM detects a second valid remote transmitter lock transmission within three seconds of the first transmission, the doors will lock again, the horn will sound for 20 ms and the parking lamps will flash for 200 ms to indicate the doors are locked. If the GEM detects the driver or passenger door is ajar during the second lock transmission, the doors are locked again and the horn is sounded twice. If the GEM detects a valid remote transmitter lock transmission within three seconds of detecting a valid remote transmitter unlock transmission, the GEM will lock all the doors
• • The doors do not lock/unlock using the remote transmitter
  • Ignition switch.
  • GEM.
  • Remote transmitter.
  • Remote transmitter batteries.
  • GO to Pinpoint Test C .
  You followed the program instructions to the letter ? Programming -Keyless Entry Remote Transmitter NOTE: All keyless entry remote transmitters (15K601) must be programmed at the same time.
  NOTE: All previous transmitter identification codes (TIC's) will be erased when programming mode is entered.
  NOTE: To program (or reprogram) the keyless entry remote transmitters into the generic electronic module (GEM)(14B204), perform the following steps.
  
  1. Turn the ignition from OFF to RUN eight times within 10 seconds, ending in RUN. If the GEM has successfully entered program mode, it will lock and unlock all the doors.
  1. NOTE: The first TIC must be entered within 7.5 seconds of entering the program mode and additional TICs must be entered within 7.5 seconds of the first TIC. The programming mode is exited whenever the timing constraints are not met.
     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.
  1. If the door locks do not respond for any keyless entry remote transmitter, wait for several seconds and press the button again.
  1. Turn the ignition switch to the OFF position, or wait up to five minutes after step 1, to exit program mode. If a keyless entry remote transmitter has been programmed (or reprogrammed), the GEM will lock and unlock all the doors one last time.
  1. Take an have the vehicle checked for DTC'S

the battery in your remote entry may be dead. suggest you replace the battery in your remote before you take it to a shop.hope this helps and thank you for choosing fixya.com

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.
• • Doors Do Not Lock or Unlock Using Keyless Entry Remote Transmitter
  • Circuit.
  • Electronic door lock control processor.
  • Keyless entry remote transmitter.
  • GO to Pinpoint Test B .

does trunk button work? panic button?
here's 2003 info:

• The doors do not lock/unlock using the remote transmitter

• Remote transmitter.
• Driver door module (DDM).

• Go To Pinpoint Test G .

SECTION 501-14: Handles, Locks, Latches and Entry Systems 2003 Town Car Workshop Manual
GENERAL PROCEDURES Remote Transmitter Programming

1. Cycle the ignition from OFF to RUN four times within three seconds. The locks will then lock and unlock, confirming that the program mode has been entered.

1. NOTE: When the first keyless entry remote transmitter is programmed, all other keyless entry remote transmitters are erased.
   Press any button on the transmitter to be programmed.

1. If additional keyless entry remote transmitters are to be programmed, repeat Step 2 within 7.5 seconds.

1. To exit program mode, turn the ignition to START or wait 7.5 seconds.
