Keyless entry on car unlocks then locks back automatic

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.

Keyless Entry
The keyless entry system consists of the following:

• smart entry control(SEC)/timer module
• keyless entry remote transmitters
• power door lock actuators
• body side door power door lock actuator
• liftgate actuator
• power door lock switches
• door ajar switches
• Principles of Operation
  All doors can be locked at once by turning the door key lock switch to the locked position. An individual door can be unlocked by moving the door key lock switch to the unlocked position and turning it again within five seconds; all the doors (including the liftgate) will unlock.
  The smart lock system is designed to keep the driver from locking his keys in the car. It will lock and then unlock all the doors if the smart entry control(SEC)/timer module detects the following conditions:
  
  • The ignition key still in the ignition.
  • A front door is open.
  • A door lock switch has been pushed to the lock position.
  The panic feature has a duration of 30 seconds from the last time the PANIC button is pressed. When locking the doors from the remote transmitter, the horn chirp/lamp flash feature can be disabled or enabled by holding the LOCK and UNLOCK buttons for two seconds. The hazards will flash three times to confirm that the feature has be enabled or disabled.

The control module probably see's an input that shouldn't be there . lock Switch , door ajar etc... Don't think it has anything to do with the remote . Some part stores have a tester to see if signal from the remote is working . Or the dealer ! Take it an see if your remote is sending a signal without you pressing any buttons .
If it is you need a new one .

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 .

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!
