Front driver-side door will not unlock - infiniti m37

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.

Theft Deterrent Arm/Disarm Modes
Important: Although mode 2 provides increased security, the content theft deterrent system disarms only by pressing unlock on the keyless entry transmitter. This can pose a problem if the keyless entry transmitter is damaged, lost, or inoperative for any reason while you attempt to disarm the content theft deterrent system.
Mode 1: The system arms when you lock the doors with the keyless entry transmitter. The system disarms when you unlock the left front, right front, or liftgate door with the key or the keyless entry transmitter. The system does not arm when you lock the doors with a power door lock switch.

Mode 2: The system arms when you lock the doors with the keyless entry transmitter. The system disarms when you unlock the doors with the keyless entry transmitter. The system does not disarm when you unlock the doors with the key.

Mode 3: The system arms when you lock the doors using a power door lock switch or the keyless entry transmitter. The system disarms when you unlock the left front, right front, or liftgate door with the key or the keyless entry transmitter.
Changing the Feature Customization Modes

1. Turn off the IP dimmer switch.
2. Turn the ignition switch to the LOCK position.
3. Remove the BCM PRGRM fuse.
4. Turn the ignition switch to the ACC position. The BCM flashes the fasten belts indicator and sounds the chime 4 times, which indicates that BCM type 4 is installed on the vehicle. At this point, the BCM has entered the feature customization mode.
5. In order to change the theft deterrent/shock sensor mode, turn the headlamp switch from OFF to PARK and back to OFF.
The BCM flashes the fasten belts indicator and sounds the chime a number of times equivalent to the theft deterrent/shock sensor mode. A transition past mode 4 repeats the sequence starting with mode 1.

6. Complete the following steps in order to change the theft deterrent arm/disarm mode:

6.1.
Insert the key in the left front, right front, or liftgate door lock cylinder.

6.2.
Rotate the key from the center to the unlock position.

6.3.
Press the horn button on the remote keyless entry transmitter.

6.4.
Count the number of chimes that you hear. The number of chimes tells you which mode you have set.

6.5.
Press the horn button again in order to change the mode. Continue to press the button until you hear the number of chimes that indicates the mode that you want.

6.6.
Turn the key back to the center position and remove the key from the door key cylinder.

In order to exit and save the current feature customization modes use the following procedure:

1. Turn the ignition switch to the LOCK position.
2. Reinstall the BCM PRGRM fuse.

If you are unable to change locking modes Theft Deterrent System Feature Customization Inoperative

Hi E,with key OFF, try spraying a little ELECTRIC CONTACT CLEANER from CRC or Radio Shack into space between switch & panel on driver's side,cycle switch back & forth 10 or 12 times.driver's side switch 'overrides' others ,if cleaner dosen't work,replace it first. Good Luck

hi
Chance are the driver side control module is not working.
Open the driver side, inner door panel and check

can be the rod going to key lock keyless entry work on a different one

Hi.

To program ( or reprogram ) a keyless entry remote transmitter into the remote keyless entry module, perform the following steps:

1. Turn the key to ON or ACC and short the two terminals of the program connector, a two-pin connector located below the driver's side of the instrument panel at the base of the steering column. All doors should lock and then unlock.
2. Press any button on each keyless entry remote transmitter in turn. All doors should lock and then unlock. If the door locks do not respond, press the button again (up to three times maximum with the same keyless entry remote transmitter). If the door locks still fail to respond, go to Pinpoint Test A.
3. Repeat Step 2 to program additional keyless entry remote transmitters into the remote keyless entry module (up to four keyless entry remote transmitters maximum).
4. Turn key off.
5. Remove the short from the program connector. All doors should lock and then unlock.
6. Verify that the keyless entry remote transmitters have been successfully programmed by pressing the LOCK or UNLOCK button on each one, and observing that the system responds by locking and/or unlocking the doors.


I hope this helps you.

Thanks!

sounds like the main acculator in the drivers door has gone bad have it replaced it should solve your problem.

Factory keyless?

The keyless entry is designed to work with the doors closed (closed - not locked). If the door ajar sensor thinks the door is open the keyless entry is disabled. When you manually lock the door it might tighten the door just enough to activate the keyless entry. I would try slamming all the doors closed and then see if the keyless entry works. If it still wont work have the wiring checked on the front door lock.

inspect and or replace the drivers door lock actuator...
