Driver side door lock button not working, and passenger side sliding door makes a buzzing noise
The driver side door lock buttons are not working on my van. I bought the van used, and after a couple weeks I noticed that when I used the driver side button to lock, the passenger side sliding door would not lock, but all the other doors would. I realized that the door lock switch on that door was stuck. I fixed it and was able to lock all the doors with the driver side lock button, but then the passenger side sliding door started making a buzzing sound when it was locking. I pushed the lock/unlock buttons a few times on the driver side door and the buzzing sound got higher pitched (almost a

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.

Lack of lubrication. Moving parts always experience friction, so a possible cause of the driver-side door locks not working is a poorly lubricated door latch. For this issue, check if the latch mechanism on the door has any corrosion that could be hindering the lock.
In some cars, a door lock actuator becomes noisy and produces a squeaking or buzzing noise when the power door locks are locked or unlocked. If the electric motor or the mechanism inside the door lock actuator wears out, the door lock may lock or unlock slowly or work sometimes but not all the time.
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.
In most cases, when a single door will not open, it`s due to a broken latch – which will require replacement. As long as you can get into the vehicle, you should be able to climb into the driver`s seat and drive home safely until you have time to contact a mechanic to find the issue and make the right repairs.
Mechanical Issues That Cause Squeaking Door Hinges
Over time, some parts on the car door can wear out and need replaced. One common issue is rusted car door hinges. While you may be able to clean off a small amount of corrosion, hinges that have an excessive amount of rust will need to be replaced to stop the noise.
On average, a door lock actuator will cost between $125 and $250 for the part alone. Some models can be significantly higher or lower, though. If you need a mechanic to do the job for you, expect them to charge between one and two hours of labor, which could be a couple hundred dollars or so.
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.
Open Settings and tap Accessibility -> Touch -> AssistiveTouch. Turn on the switch next to AssistiveTouch at the top of the screen. You`ll know it`s on when a circular button appears on the screen. You can use a finger to drag the AssistiveTouch button wherever you`d like on the screen.

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.
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.

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.
Inside driver side and passenger side door locks do not work and that is the only way that I can lock my car.
ANSWER : You may have two bad latch door lock actuators. The only way to tell is to take the door panel off and test the actuator to see if they are getting power and move freely. This is a very common problem and a mechanic can remove the door panels and test the locks out for you.
My window on my passenger side won’t roll down and the lock button doesn’t lock the doors.
ANSWER : Hello, thank you for writing in. Your issue is most likely a switch. The window motor would not effect the door lock functions. The only true way to know is to test the power available to the switch and see if it is passing through, or making it to the motor. Where the power stops and is not utilized, is the component that has failed. If the power supply is not making it to the switch, then you have another wiring or fuse issue. Without doing some electrical testing, you may want to start with replacing the switch.

ANSWER : The solenoid is on the door latch and is most likely the cause of the problem for your 2005 Toyota Tacoma. If you want to have this inspected and repaired, a certified technician from YourMechanic can come to your home or office to diagnose your door lock and perform the correct replacement.
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.
