The door switches are bad, the two door switches are connected to a single control module. If one of the switches is bad, or if there is a contact in wiring harness to switch, this will affect the central lock module, hence the problem on both doors.
To replace door switches you will need first to test them and to test wiring by reading volts. on switches you read ohms to check if they open and close the circuit. To access door switches there is need to remove the door panels, the control module instead is buried behind the dash. If you have not taken apart your 944 before , then better going to a mechanic. there is risk to damage door trims, or to mess up wiring.
If you want to DIY, then get first the repair manual:Product: Porsche 944 (83 - 89).

Keyless remote 1996 jeep grand cherokee laredo programing


Instructions
  1. Programming the First Transmitter
    • 1

      Unlock all of the Jeepicon1.png Grand Cherokee's doors and open the driver's side door. Keeping the door open, lock it using the manual lock on the door itself.

    • 2

      Put the manual key into the ignition and switch it to the "On" or "Run" position, whichever applicable, without starting the engine.

    • 3

      Point the remote at the receiver (located by the little bulb on the caricon1.png ceiling) and hold down the "Lock" button for up to 5 seconds.

    • 4

      When the driver's side door unlocks, you know the remote has been programmed correctly. If you are only programming one remote, jump to the next step. If not, manually re-lock the driver's side door and repeat steps 5 and 6 using each remote you would like to program and then continue.

    • 5

      Turn the key to the "Off" position and turn the ignition on immediately. This must be done within 20 seconds of programming the last remote. You're finished!

2001 Mercury Villager keyless remote is malfunctioning


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 .

Power locks don't work with remote or control from


The door lock/unlock input from the driver's key switch goes to the Door Multiplex control unit (main switch), the Door multiplex control unit then sends a signal on the BUS (CAN) circuit to the passenger's multiplex control unit; the passenger's multiplex control unit then controls all the door locks. The passenger's door lock key switch inputs to the passenger's multiplex control unit, if the locks work from the passenger's side key switch but not the driver's side key switch, the most likely cause is the driver's multiplex control unit (main switch) not sending the signal to the passenger's side multiplex control unit. This could also be the drivers side door lock actuator. Hope this helps!

How to program the key for my bmw 750i model 1997 to lock/unlock the door


BMW 7-Series - Key Remote Programming
Three methods to try:
Method 1:
1. Working from within the vehicle and with the doors shut
2. Turn ignition to position 1 and back to off within 5 seconds.
3. Remove the key from ignition and press and hold the unlock button for 15 seconds during this time press the key lock button 3 times within 5 seconds.
4. Release both buttons.
5. Doors will lock and unlock to show correct programming has occurred.

Method 2:
To do this procedure you need to have one working key and one key that needs to be programmed.
1) Get in and close all doors.
2) Turn on the ignition and turn off quickly. (No more than 5 seconds) to start the process. Next action must take place within 30 seconds.
3) Remove the 1st key.
4) Hold the key up near your left shoulder (this is so it is closer to the remote receiver antenna.
5) Hold down the unlock button and press the lock button 3 times. Release the unlock button and the doors lock which confirms the operation.
6) Quickly repeat steps 4 & 5 for key #2 etc.
If it does not work, try doing the keys in opposite order. Key 2 then key 1, vs 1 then 2.

Method 3:
Alternate if you do not have a working remote
1. Turn key to position 1 five times very quickly 2. Remove key 3. Hold unlock button then press lock button 3 times, release unlock button.
4. If you have another key do the same button pressing within 30 seconds 5. Turn on ignition to finalise.
PLEASE NOTE: This programming procedure programs the remote control part of the key. Any transponder chip for the immobiliser (starting of car) will not be programmed and must be done by a specialist.

Step 1: Open drivers door and leave open.

Step 2: Lock and unlock the drivers door using the power door lock switch on the door.

Step 3: Insert key into the ignition.

Step 4: Turn key to on position and return to off position. (IMPORTANT - use ON position NOT ACC position). Do this 3 times within 10 seconds. Leave key in the ignition.

Step 5: Open and close the drivers door 3 times. (Door should be left open after this step).

Step 6: ECU should respond by locking and unlocking the doors.

Step 7: Press any button on remote #1. ECU responds by locking and unlocking the car doors.

Step 8: Press any button on remote #2 (etc.) Each time the ECU will respond by locking & unlocking the doors.

Step 9: Remove the key from the ignition and the ECU will respond a final time with a series of door locks and unlocks. You're done

Power locks not working right


Hey, this might work.....get in truck, close doors, put key in ignition in lock position.....hold down the door lock button on driver side door control and wait for the lock control to be displayed on the information screen(odometer read-out).....it should say like lock 1, lock 2, lock 3, lock 4.....or something, I always reset mine to LOCK 1, to do this hold the odometer reset button on dash for a sec or two til it changes settings, then release, repeat till you get to LOCK 1, then quickly press and release odometer reset button to exit program, this is the function to lock doors over 15 mph and when out of park and to unlock doors when returned to park......yours' might be set to another function number....try it out, let me know if this helps.........good luck!
