How to install a Sierra tools keyless entry system?

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

Keyless Entry System Description and Operation - Passive
Passive keyless entry allows entry to a locked vehicle without pressing any buttons on the keyless entry transmitter. You must only have the transmitter with you. This passive system is also part of the vehicle starting system. It allows you to start and run the vehicle having only the transmitter as your key. The passive entry and starting system use low frequency antennas in 4 different areas on the vehicle to determine the location of the transmitter. When passively opening a locked door or the rear compartment lid, you must have a programmed transmitter with you in your pocket, purse, or briefcase. As a customer opens the door handle or presses rear compartment touch pad, the low frequency antenna sends out a challenge to the keyless entry transmitter. The transmitter must be in a one meter range of the door or rear compartment lid in order to receive the challenge. If the challenge is met, the transmitter will respond, allowing the door to be unlocked and opened. Passive entry allows you to operate the following features:
• Passive door unlock/unlatch
• Passive rear compartment lid release
• Illuminated entry lamps
• Vehicle starting
The keyless entry system has the following components:
• Keyless entry transmitters
• LH and RH door antennas (part of the door handle assembly)
• Rear compartment antenna
• Console passive antenna
• Console active antenna
• Instrument Panel Module (IPM)
• Rear Integration Module (RIM)
• Remote Control Door Lock Receiver (RCDLR)
• External RF Antenna (includes coax from RCDLR to back glass)

Remote Control Door Lock Receiver (RCDLR)
The RCDLR is a multi-function module which controls all the vehicles antennas for passive keyless entry functions. The RCDLR also acts as the receiver for active keyless entry and tire pressure monitoring (TPM) functions, as well as controlling all immobilizer functions.
The RCDLR's RF antenna is located in the back glass, and there is a coax cable connecting the glass antenna to the module located in the trunk.

Your best bet , take it to a qualified repair shop that has the factory Tech 2 scan tool or someother professional type scanner that can read • Rear Integration Module (RIM) DTC'S - diagnostic trouble codes .

Time for a new key fob ? Does it work good for locking the doors ?
Module Controlled Functions The multifunction modules consist of the following:

• generic electronic module (GEM)/central timer module (CTM)
• remote anti-theft personality (RAP) module (15K602)

The remote anti-theft personality (RAP) module controls the keyless entry, and computer operated locks systems.
The GEM/CTM controls the following features:

• wiper/washer (front/rear)
• warning chime
• battery saver
• illuminated entry and courtesy lamps
• driver one touch down power window (GEM only)
• accessory delay

• Keyless Entry The keyless entry system components consist of the following:
  
  • keyless entry remote transmitter (15K601)
  • remote anti-theft personality (RAP) module (15K602)
  • driver unlock relay (if equipped with two step unlocking)
  • all unlock relay
  • all lock relay
  • keyless entry keypad (14A626)
  The electronic door lock system has three main components: the remote anti-theft personality (RAP) module, attached to the rear left hand quarter panel, the three-button (hand held) keyless entry remote transmitter (15K601), and the keyless entry keypad (14A626) on the driver side door.
  The door locks are controlled by the RAP module through three external relays: the driver unlock relay (if equipped with two step unlocking), the all unlock relay, and the all lock relay. These relays are located in the relay box on the LH rear quarter panel.
  The keyless entry remote transmitter initiates the following electronic door lock system functions:
  
  • Unlocks the driver door (if equipped with two step unlocking).
  • Unlocks all doors.
  • Locks all doors.
  • Enables the panic alarm.
  • Issues the interior lamps on (when unlocking) and off (when locking) commands to the generic electronic module (GEM).
  • Sounds the horn (13832) once when LOCK on keyless entry remote transmitter is pressed twice, and doors are closed.
  • Sounds the horn twice when LOCK on the keyless entry remote transmitter is pressed twice, and any door or the liftgate window is ajar.
  • Allows up to four keyless entry remote transmitters to be programmed.
  • The order that the transmitters are programmed into the module will set the memory seat to the corresponding position when the driver door is unlocked with the transmitter.
  NOTE: The remote entry features will not function when the ignition switch (11572) is in the RUN or ACC position.
  The keyless entry remote transmitters are reprogrammable and must be set at the same time.
  To confirm that the doors have been locked and that the anti-theft system has armed, press the LOCK button again, within five seconds of the first press. The horn will sound once if the doors have locked and all doors are closed.

Keyless Entry System Description and Operation - Active
The keyless entry system is a vehicle entry device. The keyless entry system is used in conjunction with the door locks to unlock the vehicle. Keyless entry will lock/unlock a door or open 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. A low transmitter 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, such as gas stations that use pay-at-the-pump RF transponders, may also cause interference that could lead to a malfunction. Keyless entry allows you to operate the following features:
• Door lock/unlock
• Rear compartment lid release
• Illuminated entry lamps
• Panic alarm/Vehicle locator
• Remote vehicle start

Your best bet , take it to a qualified repair shop . Dealer

All pre 1995 GMC vehicles had to have an alarm system to have keyless entry... So, lift the hood and look for a red LED near the right front of the vehicle. If none - you don't have keyless... if yes, the you do.... and an alarm system too.

The driver door module (DDM) is connected on the standard corporate protocol (SCP) communication network. The DDM controls many functions including power windows, power door locks and remote keyless entry. The DDM also communicates with the driver seat module (DSM) to control the power mirror and seat memory functions.
Do you know anything about automotive electronic control modules ?
The driver door module (DDM) receives inputs from the digital transmission range (DTR) sensor, ignition switch, seat switch, window/door lock switches, lighting control module (LCM), keyless entry keypad switch and remote transmitter. The DDM outputs consists of keyless entry keypad switch illumination, power door lock actuators, luggage compartment release solenoid, horn relay, and lighting control module (LCM).
Best thing to do would be to have a factory scan tool hooked up to check for DTC'S diagnostic trouble codes . That should be the first step if it's not programming the code.
