My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hello – the first level of diagnosis is to isolate which component does not lock the doors as expected: master door lock switch on the driver door, the lock button on the key fob, etc. If only one of these does not work, that component can be replaced, restoring the locking function. Try an alternate key fob for example to help isolate the failure. If door locking does not work at all, the problem is larger – perhaps a door lock relay, body control or security module issue. I recommend an electrical inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
How to Identify and Fix Common car Problems ?

Fortunately, this is often an easy fix. Simply grab a can of WD-40, silicon-based lubricant, graphite spray, or a dry lubricant and spray it into the keyway. Once it has been sprayed, insert the key so the lubricant will work into the locking mechanism.
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.
Five of the most common reasons for a car door lock not working properly are a dead battery in the key fob, bad programming in the fob, a blown fuse, a bad solenoid or a broken wire.
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.
Factors like the weather, damage to the key, and even a buildup of dirt and grime inside the locking mechanism can all stop a door from locking. If you`re having trouble locking your front door on a regular basis, you should consult a locksmith as soon as possible.
The car`s central locking is not working with the key: This problem may arise if the key fob has an issue or the fob`s battery is dead. You can try replacing the batteries or getting the key remote diagnosed at the service centre.
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.
If only one door isn`t working, there`s likely a problem with a door switch or sensor. If this is the case, you`ll need to have a mechanic take a look at your car. If all of your doors don`t open, you could have a blown fuse.
The simple answer is you should not use WD40 to lubricate locks. WD-40 is one of the solvent-based lubricants and does not contain any lubricant and over time can make your lock even stickier by gumming the lock up.
A blown fuse prevents power transfer to the actuator, thus disabling the lock system.
The majority of cars now have remote central locking, however, with a flat or dead battery this won`t work and you will be forced to use the key to open the car doors.
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.
Electric Locks – Internal
It has a low voltage solenoid in the mechanism which is driven by a DC power source. Shear locks allow the door to swing in both directions and lock in place via two pins that lock the armature onto the magnet. We offer an extensive range of electrc locks by Abloy UK.
The solenoid lock denotes a latch for electrical locking and unlocking. It is available in unlocking in the power-on mode type, and locking and keeping in the power-on mode type, which can be used selectively for situations. The power-on unlocking type enables unlocking only while the solenoid is powered on.
There are several places where the blend door actuator can be found. The majority are, however, located close to the blower fan, behind the dashboard. Remove the controls, or perhaps look underneath the dashboard, in order to locate it.
The average cost for a Door Lock Actuator Replacement is between $297 and $346. Labor costs are estimated between $95 and $120 while parts are priced between $202 and $226.
Car door locks may stop working because of a weak battery or faulty alarm.
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.
If your vehicle is equipped with Passive Locking, the doors and liftgate will automatically lock within several seconds after the vehicle is turned off, the key fob is out of the vehicle and all doors are closed.
If the switch fails completely, it will not be able to conduct power to the door lock actuators, and as a result, the door locks will not function. While most power door lock switches are built to withstand extended use, they are still susceptible to failure, and can be an inconvenience for the driver when they do.
The only tool required to check a relay is a multimeter. With the relay removed from the fuse box, the multimeter set to measure DC voltage and the switch in the cab activated, first check to see if there are 12 volts at the 85 position in the fuse box where the relay plugs in (or wherever the relay is located).

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.
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.
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.
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.
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.

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.
