Front Passenger Lock sometimes does not lock with a remote control or by locking button located on either doors.
Greetings: When locking the car using either with the remote or with the lock button located on either doors, the front passenger door sometimes won't lock. All other three (3) doors lock every time. Is solenoid part of internal door lock? So if I purchase the door lock to replace the faulty one would fix this issue? Thanks
My car has 140000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
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.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
If the locks begin to work intermittently, you may have a broken wire. Extremely cold weather has caused the mechanism to freeze. Because the doors on your car are not fully moisture-proof, extreme cold may cause the linkage controlling your power locks to freeze. The solenoid needs to be replaced.
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.
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 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.
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.
In a central locking system, the solenoid in each door will activate the lock or unlock function. If you are finding the locks are working intermittently and of their own accord then it could be due to broken wires or a faulty connection. This will cause intermittent power from the key fob to operate the locks.
For safety/security reasons, the single button push opens only the drivers door. This is to avoid the chance that someone hiding on the opposite side of the car could hop in simultaneous with you. The 2nd push of the same button is to unlock the other doors, and the external trunk/hatch lock as well.
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.
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.
Door lock actuators are an electronic component found on vehicles equipped with power door locks. They are the electronically controlled actuators in every single door that are responsible for locking and unlocking the power door locks when the switches are pressed.
On many modern vehicles, the lock actuators are monitored by electronic controls (such as the body control module) that have to receive the correct antitheft code from a key fob transmitter before they`ll send electrical current to unlock the doors.
The Differences
Keyless entry systems almost always have a conventional key backup, while remote keyless entry systems may not. Keyless entry systems are only limited to locking and unlocking the door.
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. There are also a number of reasons that your car door won`t lock.
Press and hold the “lock” button on your car remote for one second, then put the key into the ignition, and turn it on.
A door lock relay can be located in four different places on a vehicle, including: Under the dash on the wall by the brake pedal. Under the dash in the middle of the cab behind the stereo. Under the dash behind the passenger air bag.
If the locks on all doors suddenly stop working or responding, the key fob may be to blame. A dead battery or a malfunction may prevent the fob from sending a signal; in this case, the key fob may need to be reprogrammed or replaced.
When your car key fob doesn`t unlock the doors, try every other entry mode to determine whether all connections are still intact. This could require the replacement of the entire lock system in certain circumstances, but it might also be as simple as replacing a simple screw.
When the alternator fails, other systems that are connected to it may also start to malfunction. These include things like power windows, locks, lights, air conditioning, and even your radio.
When your alternator is malfunctioning all the systems in your car that require electrical power may start to go haywire. Issues with the power windows, central locking, dashboard lights and even your air con and stereo could start to occur.
Car key sensor is not working: If the key is not working at all, it may be due to the drained battery, faulty fob, low car battery, or faulty keyless entry system (if applicable). You can try replacing the fob batteries, diagnosing the fob or towing the vehicle to a service centre to fix the issue.
To test a linear actuator`s current draw, simply connect a multimeter in series with one of the leads of a powered linear actuator, and watch the amperage reading as you extend/retract the rod. Based on the reading, you can determine a power supply that will be able to handle that current draw.
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 …
Applied Voltage: Solenoids require alternating current (AC) voltage for activation and motion because they use a magnetic field for operation, and only the AC voltage can create the magnetic field. Linear actuators tend to use DC motors, which cannot operate with AC voltage.

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.
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.
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.
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.
Front doors not locking with fob.
ANSWER : The front door lock actuators are controlled by the their respective door switch units. The rear lock actuators are controlled by the Body Control Module. When the key fob is pressed to lock or unlock. The Body Control Module receives the request and then locks/unlocks rear doors and sends a signal to both the drivers door and passenger front door switch assemblies over a computer data line to lock/unlock front doors. Since the rear door locks are operating, one of two things is happening, either the door lock/unlock request is being interrupted on the computer data line or the Body Control Module is not sending the request to lock/unlock doors to the data line. One way to see if the problem lies with the data line or the Body Control Module is to try to lock or unlock all doors from the driver’s door switch. If the rear doors do not lock/unlock then the data line to the Body Control Module is open and will need to be traced to locate the open circuit and repaired. You may want to enlist the help of a mechanic, like one from YourMechanic who can scope out the data line to see if the signal is being interrupted and to locate and repair the open circuit.
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.
Car won’t stay locked when I use the remote to lock
ANSWER : The doors locking right after you unlock them or unlocking after you lock them are a safety and security issue concern. After checking into this issue I have learned that other owners have had the same issue and usually end up replacing the door lock actuators in each door. As this can be costly, I would suggest you contact YourMechanic to get a thorough diagnostic to verify the cause of your issue. YourMechanic can verify if any recalls or Technical Service Bulletins (TSB) pertain to the repair of your vehicle. They can verify if it is a bad door lock actuator and/or latch. There are no recalls as of the writing of this article, there are, however, owners that have had complaints with door locks. In May of 2015 there was a lawsuit for the door locks malfunction, that was a class action lawsuit, that may help you at the dealer to get repairs done.
