2003 Chev Silverado, remote entry problem.

2003 Chev Silverado, remote entry will not work. Dealer tested fobs (ok) but says the BCM will not communicate with the receiver. Wants $500 for new BCM. However doors all receive lock signal at ~20 mph, which indicates BCM is communicating with door modules. Could it be the receiver, and if so where is it?

Buy a used BCM from a auto salvage yard . $20 buck's , Or buy a reman one .then have the dealer program it . Rather then guessing an replacing part's ( receiver ) They have a factory scan tool , do you ? They can view data inputs to the BCM ,can you ? They can tell if the module is communicating ,can you . They have factory service repair information ,do you ? Just because you don't like their price . These people have reman auto control module's

SOURCE: driver door won't lock with key fob

Check the locking solenoid / actuator in the door behind the panel, could be burned out or loose wire. It should take about 20-30 minutes to open, fix it and close the door panel if there's no major problem. Autozone might be able to help out with a solenoid.

SOURCE: hazard lights flash by themselves, doors won't stay locked (unlock by themselves) key fob won't work.

I has a similar problem and I just took the battery out of my remote. I think there is a problem/ short in the remote. It's as if the button is being pressed when it is not. I will use my spare one in the mean time. It was driving me crazy becuase I was driving long distance at the time and when I removed the battery it stopped. I hope this works for you!

Hello and thank you for using FixYa!

Most likely the remote has failed. If you have another remote for the car, try it. All features should work on the spare remote. You will need to get another remote and program it to correct this. Here is a link on how to program it.

Thanks Jay!

I have a 2004 yukon xl 1500 2WD and the keyless entry has stopped working. Replaced the fobs a year ago and that fixed the problem for awhile. Where is the module located and which fuse protects it?

Your best bet , take it to a qualified repair shop that has a diagnostic scanner that can check for DTC'S - diagnostic trouble code's an input's from the fob's an messaging from the passenger door module to the BCM. Does the power window & power locks work for the passenger door ? If so , it's not a fuse .
The keyless entry system has the following main components:
• The transmitters
• The passenger door module (PDM)
The PDM communicates with the body control module (BCM) through the keyless entry serial data circuit. When you press a button on a transmitter, the transmitter sends a signal to the PDM. The PDM sends a request to the BCM and the BCM performs the appropriate function.

Diagnostic System Check - Remote Keyless Entry
The numbers below refer to the step numbers on the diagnostic table.
Lack of communication may be due to a partial malfunction of the class 2 serial data circuit or due to a total malfunction of the class 2 serial data circuit. The specified procedure will determine the particular condition.
The presence of DTCs which begin with "U" indicate some other module is not communicating. The specified procedure will compile all the available information before tests are performed. Any other body control module DTCs displayed by the scan tool do not apply to Remote Keyless Entry and should be diagnosed in the applicable section.

Install a scan tool.
Does the scan tool power up?
YES - Go to Step 2
NO - Go to Scan Tool Does Not Power Up in Data Link Communications
Turn ON the ignition, with the engine OFF.
Attempt to establish communication with the following control modules.
• body control module
• passenger door module
Does the scan tool communicate with all of the listed control modules?

2012 ford f350 door locks only work manually key fob has been dead for years now door lock button does not work cant seem to find fuse location in my book ?

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.

Which fuse powers the power door locks on a 2012 equinox? None of the doors lock or unlock with the fob, battery ok

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

Your best bet , take it to a GM dealer .

The driver's side door will not lock or unlock via remote control. What is the solution for this? All other doors lock/unlock when remote is used.

is it freezing there? (ice happens)
car drives perfectly day and night? (tells me battery not dead or weak)

does outside metal key work, does inside lock lever work?
if not its frozen inside.

ill assume the 2 mech, ways work and solenoid is dead.
get car serviced?
do you have tools, and skills?

this, its a solenoid. seen below. inside the door.
5003 378AA - 97 keyless entry (electronics,only for 1997)
ZJ jeep
The FOB battery weak can cause this, try both fobs yet.
one door RKE receiver (hidden below) can be weaker or stronger.
and may fail if the RKE (fob) is weak. Rem.key entry=RKE
so a new battery in the fob is a now thing.
22year old FBO battery? hopeless if ever.
ok if the manual doors work ok and only a good fob fails (both)
(car came with 2 so...)
then the problems is below.
here is an example of how complex it can be. and real solutions.
93-97 location. reciever.
Just pry up the defroster grille panel and it will be on the passenger side, held in by 2 screws.
scan the PCM first. looking for RKE errors, BCM errors>?
if 12vdc does not reach the solenoid,
then the Door controller failed or the BCm fail to sen the command or the remote receiver (entry) module never sent it.
my guess is the RER is ok, as it opened other doors.
so that leaves, BCM mess up. or soldenoid bad.

here is the receiver. that is failing, if 2 fresh fobs fail.
fresh batteries.
some green PCB below are in overhead lamp module
others are in door, (sun roof?)

i think this is 1999.

this found on some 97s. RER
remote entry receiver. module.

Rocker switches,nor remote will lock or unlock doors fuse good

So , the power door locks won't lock or unlock with switches inside the vehicle or with the keyless entry remote fob.??? Is this correct ????
Do you know what a BCM - body control module is ? Do you know what diagnostic trouble codes are ? If not your best bet would be to take your vehicle to a GM dealer or someother qualified repair shop.
DTC B3142 or B3143
The body control module (BCM) provides an output to the driver switch assembly through the door unlock control circuit for controlling automatic door unlock, anti-lockout, and keyless entry unlock functions.
DTC B3152 or B3153
It could be the driver door master switch , could have broken wires inside the rubber boot from the body to the door . Do the power windows work ?
The keyless entry system has the following main components:
• The transmitters
• The body control module (BCM)
When you press a button on a transmitter, the transmitter sends a signal to the BCM. The BCM interprets the signal and activates the requested function.

How did you do this ,,checked and made sure locks and remote programmed,they were,but still do not work ?????

Need a scan tool to program
Important: All key fobs must be programmed each time any one fob is programmed. The scan tool must stay connected until all of the transmitters are programmed.
Install a scan tool and navigate to the BCM Module Setup menu.
Select Program Key Fobs.
Follow the scan tool on-screen directions.
When the programming operations have completed, operate the transmitter functions to verify correct system operation.

Keyless entry does not unlock doors, open trunk, or start vehicle (remote start built onto keyless entry). Battery is new in BOTH remotes and neither one works. Could a fuse in vehicle be bad? Secondly,...

RFA / MOD fuse 10amp . location - insturment panel fuse box. Fuse Block - I/P
Right side of the I/P, behind the access panel
If the fuse is good your best bet would be to take it to a qualified repair shop , that doesn't mean the dealer . Lot of good independant repair shops around , just have to check the yellow pages.
Do you know what DTC'S are ? diagnostic trouble codes ! Not only the ones for the engine management system OBD 2 . There are also DTC'S for the remote keyless entry system , BCM - body control module. You need a factory or professional scan tool to view this codes
DTC B3101

DTC B3103
DTC B3106

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 a lock, unlock, or panic alarm request to the BCM, depending on which button is pressed on the transmitter. The BCM receives the message and performs the appropriate function. The BCM also uses the keyless entry serial data circuit in order to communicate with the RCDLR when programming transmitters. Do you know what serial data circuits are ?

DTC B3101 Keyless Entry Data Link Circuit Range/Performance
DTC B3102 Keyless Entry Data Link Circuit Low
DTC B3103 Keyless Entry Data Link Circuit High
DTC B3106 Keyless Entry Data Link Parity Error

This is what the factory manual said as to the location of power steering fluid reservoir ! Not much help , you would do better googling it.
The power steering fluid reservoir holds the power steering fluid and may be integral with the power steering pump or remotely located. The following locations are typical locations for the remote reservoir:
• Mounted to the front of the dash panel
• Mounted to the inner fender
• Mounted to a bracket on the engine

Seriously don't use the factory alarm system / keyless entry.

While my car was under warranty, the alarm malfunctioned and it wouldn't disarm. The solution was to have the car towed to a dealership and install a new BCM. This would have cost me over $1,000 - and it's not an isolated case.

Don't get a Hyundai key fob. Have an after market alarm / keyless entry installed. It will be cheaper & easier.
