Power door locks keep unlocking, and then when unlocked they keep clicking to unlock repeatedly, the car will not stay locked and had to disconnect the battery to keep it locked and so not to need a jump the next day or after work, 2007 Nissan Altima 3.5 SE. Thank you

After Market alarms are always full of issues especially when the batteries are disconnected of the car batteries are disconnected.

Find a Viper Alarms installer and take it in for reprogramming with their pro grade scan tool computer.

The BCM - body control module is what controls the power lock's , disconnecting power can cause some functions to need resetting .
Have the BCM checked for DTC'S - diagnostic trouble code's , that would be my first step . Do you know what wiring diagrams are an how to read them ? Free wiring diagrams here

Battery Disconnect or Replacement Problems


Driver Door Unlock Operation
When any of the door lock switches are placed in the unlock position, a ground signal is applied to the BCM through the door unlock signal circuit. Upon receiveing this signal, the BCM grounds the control side of the driver door unlock relay through the driver door unlock relay control circuit. Since the other side of the driver door unlock relay winding is connected to battery voltage, the relay is energized. This causes the contacts to close and complete the path from the DRV LKS fuse through the battery voltage circuit. Voltage is then applied to the unlock side of the driver door lock actuator through the driver door lock actuator unlock control circuit. Since the other side of the the driver door lock actuator is connected to the normally closed contacts of the door lock relay to ground, the driver door unlocks.
The driver door unlock function can also be accomplished by the BCM supplying ground to the driver door unlock relay control circuit by either of the following:
• A keyless entry unlock transmission
• A lock out prevention function

DTC B3130 00: All Door Unlock Circuit
DTC B3135 00: All Door Lock Circuit

Circuit/System Description
When any of the door lock switches are placed in the lock position, a ground signal is applied to the BCM through the door lock signal circuit. Upon receiving this signal, the BCM grounds the control side of the door lock relay through the door lock relay control circuit. Since the other side of the door lock relay coil is connected to battery voltage, the relay is energized. This causes the contacts to close and complete the path from the battery voltage circuit. Voltage is then applied to the lock side of the door lock actuators through the door lock actuator lock circuits. Since the other side of the all the door lock actuators are connected to the normally closed contacts of their respective unlock relays to ground, the doors lock.

no you needs a new lock actuator on that door its about $90 installed,
all the locks are on same circuit . sorry about the bad news :(

Your Focus may be equipped with the autolock feature. Try this:

To deactivate/reactivate the autolock feature using the power door unlock control

You must complete steps 1-7 within 30 seconds or the procedure will have to be repeated. If the procedure needs to be repeated, you must wait 30 seconds.

1. Turn the ignition key to ON.
2. Press the power door unlock control three times.
3. Turn the ignition key from ON to OFF.
4. Press the power door unlock control three times.
5. Turn the ignition back to ON. The horn will chirp.
6. Press the unlock control, then press the lock control.
The horn will chirp once if autolock was deactivated or twice (one short and one long chirp) if autolock was activated.
7. Turn the ignition to OFF. The horn will chirp once to confirm the procedure is complete.

You will probably need to take your Cutless into an auto electrician. Until you can take it in, I suggest disconnecting the battery when you aren't driving. This way the battery won't be drained. It is usually simply a matter of unscrewing the cord connecting to the battery. It can be found in the driver's manual or online if you need to know which cord to disconnect.

Unlock vehicle. Enter vehicle. Close driver's door. Switch ignition ON and OFF. Remove ignition key. Press and hold unlock button. Press lock button briefly 3 times within 10 seconds keeping unlock button depressed. Release unlock button. Some models: LED flashes slowly for 10 seconds. Some models: Central locking system locks and unlocks rapidly to indicate correct programming. Repeat above procedure if central locking system does not work and LED does not flash or LED flashes continuously.

Synchronization
When
Key buttons operated repeatedly while vehicle out of range and system becomes inoperative.
How
Press key lock or unlock button for approximately 1 second. Manually lock or unlock vehicle. System should now lock or unlock vehicle. If not, carry out programming procedure.
Programming
When
Key added or replaced. System malfunction.

Keys can only be programmed using diagnostic equipment.
NOTE: A maximum of 4 keys can be programmed.
How - 99MY

Switch ignition ON. Insert key to be programmed into driver's door lock. Lock vehicle manually. Press lock or unlock button. Wait at least 1 second. Press lock or unlock button again. Vehicle horn sounds to indicate correct programming. Keys can also be programmed using diagnostic equipment.
NOTE: A maximum of 4 keys can be programmed.

your remote may have dying batteries.

Replace fuse 57 (15 amp) then disconnect battery and wait 30 to 45 minutes before reconnecting the battery.

My 2006 BMW 325I had the same problem with the door locks not responding. I checked all related fuses and found #57 (15 amp) was the only related fuse blown. I put in a new fuse and it still would not work. I then disconnected the battery for a while then once I reconnected the battery everything worked fine.

I believe I blew the fuse while repeatedly pushing the unlock button rapidly while walking across the parking lock to the car. I suggest only pushing the unlock button only once or twice.

Im no professional but i did recently buy a 93 maxima and i have the same security alarm problem and my powered locks dont work at all. im taking off the door panel today to take a look and see if the alarm sensor is loose or damaged, if it is, ill probably just disconnect it. one thing i have noticed though is that when i hit the lock or unlock button, i hear a faint click from the dashboard area which im assuming is the solenoid on a transistor which would mean that the buttons work but the transistor isnt delivering power. Semi-Solution for Locks: Listen for very quiet click when you lock/unlock doors, if you hear it, uve got major work to do, if you dont, then take apart the door and check the switch connections. Semi-Solution for Alarm: take off the door panel and disconnect the sensor.
