The difference between power-to-lock and power-to-unlock has to do with whether energy is needed to lock or unlock the safety door. For safety reasons, the power-to-unlock principle is preferable. After a proper risk assessment, the power-to-lock principle may also be applied.
Power door locks use electric motors to engage and disengage the door locks on your car. Owners can control their door locks via door- or console-mounted switches or buttons or remotely by a key fob or smartphone app.
Fail safe locks automatically open during a power outage because they require electricity to stay locked. Commercial building owners usually install fail safe locks on entry and exit points—such as doors to enter and exit emergency stairwells.
Power door locks (also known as electric door locks or central locking) allow the driver or front passenger to simultaneously lock or unlock all the doors of an automobile or truck, by pressing a button or flipping a switch.
The Power Locks Don`t Work

A problem with one lock is probably due to the lock actuator or another malfunction inside the mechanism of the door itself. But if none of the power locks work, check the fuse box in your vehicle. A blown fuse can cause the power locks to stop working.

As you enter or exit the car, the vehicle sends a radio signal to the key fob. The fob responds by relaying its code to the vehicle. The vehicle recognizes this code and unlocks or locks the car doors.
Locking your computer keeps your files safe while you are away from your computer. A locked computer hides and protects programs and documents, and will allow only the person who locked the computer to unlock it again. You unlock your computer by logging in again (with your NetID and password).
Electrified locks come in various types from bored locks, mortise locks, exit devices, and magnetic locks.
The behind-the-scenes mechanism that locks and unlocks your vehicle`s doors with the push of a button is the power door-lock actuator. Mounted inside the door, it includes an electric motor, gears and linkage, or a cable that extends or retracts to operate the lock.

With the Lock mode engaged, an optimal torque split between front and rear axles is locked in, instantly increasing traction. Instead of waiting for wheelspin or some other trigger to engage maximum grip, using the Lock mode tells the AWD system that maximum grip is required, right away.
Benefits of keyless technology

With some keyless technology, you don`t have to worry about that as the car will automatically lock itself once the fob is out of reach. This handy feature eliminates the chance of ever accidentally leaving your car unlocked and unattended.

Yes, it is possible to lock your keys in the car even if it has a keyless entry. If you have ever accidentally left your key fob in the car and shut the door, you know this can happen. The best way to avoid locking your keys in the car is to always check that you have your key fob with you before leaving the car.
Yes, a wedge can be used to create a gap between the car door and the frame, which can allow you to insert a tool to unlock the door. However, it is crucial to use a wedge that won`t damage your car`s paint or door seal. You can use a plastic wedge or even a deflated blood pressure cuff.
Passive Locking — Automatically locks doors and trunk/liftgate after you turn off the vehicle, exit with the key fob and close all the doors. Passive Unlocking — Determine which doors unlock upon the first press of the button on the driver`s door.
One common cause is an actuator. Also, worn wiring or a ruined door sensor are common culprits. Another cause could be how old your vehicle is. Although you must take your car to the mechanic to identify the issue, it is always helpful to research and discover the cause yourself.
The door control module (DCM), also called a door control unit (DCU), is a type of automotive electronic that provides intelligent control for vehicle doors, and their peripheral electric parts and components, that enable features such as power windows, anti-pinch technology, central door locking, rearview mirror …
One common reason the car door lock is stuck in the locked position is due to broken connections within the door panel or lock assembly. These include a broken link from either the handle, lock cylinder, or interior locking post/switch to the car door latch.
The key fob battery is dead: This is one of the most common reasons why your car door lock is not working. If your locks aren`t working, replacing the battery in the key fob could solve the issue. The key fob is faulty: If the battery isn`t the problem, the issue may be with the fob itself.

all doors lock only by inserting key in passenger side door and locking
ANSWER : Your central locking system may have been designed with a control module in the circuit. This is a small computer that is responsible for controlling the different functions of a particular system. It is possible that the module for your central locking system may have shorted out internally preventing particular functions from working properly. I would recommend having a certified technician test your central locking module to determine if all of its functions are working properly.

Having problems with door locks on 08 Cadillac CTS. Driver side door especially and will not lock or unlock with key. Others loc
ANSWER : This is often related to a malfunctioning door lock actuator, a blown fuse or a faulty power door lock switch. When you use the door lock switch in the car it sends a signal to a relay which then activates an actuator inside the door. The actuator is the final step in the process in that it is a small motor with a set of gears that actually locks and unlocks the latch mechanism inside the door allowing the door to open. When this motor is bad, the latch mechanism will fail to operate and cause the door not to unlock as it is designed to. In the case of a bad door lock relay, the power, normally needed to send the signal from the switch when you activate it to the actuator motor is not there. This means the relay is not allowing the circuit to be completed and the actuator motor is not activated. Any of the above may cause your power door lock switches not to work properly and should be diagnosed by a qualified mechanic. I would suggest having a professional from YourMechanic come to your location to take a look at the door locks in your vehicle.

Doors wont lock or unlock with fob or switch?
ANSWER : Hello. Further testing should be done to help solve your problem. Being that the door unlock reprogramming procedure has already been done and the fuses have been checked there’s not much left it could be. When you hit the unlock button you should hear a little noise in each of the doors. If you hear the noise that means that the motor inside of the door actuator is working therefore it is likely the actuator itself as the problem. Though if you do not hear any noise that means it is likely the motor inside of the actuator. The actuator motors are very common failure on Lexus. The Lexus Community is almost an uproar because the a L in Lexus should also stand for luxury but there have been widespread simple problems reported such as this. A technician such as those we have here at yourmechanic will be able to diagnose your door lock issue for you firsthand. But if you consider following the test I suggested that should help you narrow down to a solution as well.

It may also be a beneficial to take a door panel off and probe a multi meter to the door actuator connectors to ensure they are receiving the proper power and ground when the buttons are pressed. If they are that only leaves two things that can be at fault. The door actuator or the motor inside of the door actuator.

Driver and Passenger doors won’t lock, but I hear them click and see the locks twitch.
ANSWER : If the same problem is happening even when you use the inside door lock switch then the most likely cause of the locks not moving is going to be weak actuators. You should replace the drivers lock actuator first since it is used the most and you will see it fixes the problem. Then you can replace the other doors as needed.

Driver side door lock button not working, and passenger side sliding door makes a buzzing noise
ANSWER : Hi there. These door issues are common on this vehicle. Most of the time the main issue is the master door lock switch on the driver door. It sounds like you already replaced that. As for the sliding door problem, most of the time, this is a failure within the door module or it can be a connection issue.

I typically take the door apart and check the connections on the module and inside of the door just to make sure that there is nothing apparent in there. If the connections and the wiring are fine, then I use a scan tool to check the module to see what the inputs and outputs are doing. If you need to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your door problem and recommend a repair.

ANSWER : Hi there. In general, wiring harnesses are sold by the manufacturer as a whole harness; not individual wires. It is much easier, cost-efficient and safer to replace the entire harness if it’s determined that it is faulty and the source of your alarm / door issue. It would be best to have one of our mobile mechanics come to your location and complete an electrical problems inspection though, as it’s possible that this issue is related to an error code trapped in the ECU. If this is the case, simply clearing the code will resolve the problem. If the issue is determined to be the wiring harness or an exposed wire, they can recommend and most likely complete the repairs as well.

Doors lock and Unlock when vehicle is off and parked!
ANSWER : Hello, thank you for writing in. The vehicle may be having an issue with its body control module. Due to the locks doing this on their own, and the issue with the key-less entry (which works on its own circuitry), the issue is likely the components they have in common. This will include the body control module, fuse systems, or a short somewhere. Testing will need to be done when the system is experiencing the symptoms, and you may need to replicate them at the needed time. Due to the timing in which this happens, you will want to locate where the extra supply of power to the locks are coming from. Find this, and you likely will find your issue. For more help resolving the issue, contact our service department to schedule an appointment.

Door lock problems
ANSWER : Hi there. There is a resistor for the door locks that keep a voltage on the driver door lock cylinder to activate the secondary door locks electronically. If the resistor is leaking (losing power) it tends to cause the door locks to not work. You can try unlocking the driver door, then open the driver door and use the key to unlock the other doors. This will supply power directly to the driver door lock cylinder and bypass the resistor. If the other doors unlock, then the resistor needs replaced. If the doors do not unlock with the key and the driver door open, then the door lock cylinder on the driver door will need replaced. If you need further assistance with your doors not unlocking when turning the key twice, then seek out a professional, such as one from Your Mechanic, to help you.
