How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

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.
Most of the time this is due to a bad connection or a failing ignition switch. If this is occurring with the locks as well as a power loss then you may have a bad ignition switch.
The two most common causes for this issue are that the door`s unlock time is set too low or the DPI (Door Position Indicator) indicates the door is already open.
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.
Hit the Windows keys, type “sign in”, and choose Sign-in options. In the Require sign-in section, select Never from the dropdown menu. While you are in Sign-in options, make sure to disable Dynamic lock by unchecking the option in the Dynamic lock section.
The most common reason for a door opening on its own is a problem with the hinges; It`s not difficult to fix this problem by yourself. But if the cause lies in an improperly installed door, you would have to call a professional to do this for you.
Most of us have suddenly thought, “Wait — did I actually lock the door?” For some people, this might lead to locking up with more intention next time. But for others, it may be an anxiety disorder. Researchers say it`s all about being afraid of losing control.
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 …
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 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.
Tap the Settings Gear Icon in the top right-hand corner on the lock circle screen. Select the lock from the devices shown. Select Auto-Lock, which is listed in the automations menu.
On Android devices, the screen automatically turns off after a set idle period to save battery power. To unlock the screen, drag the lock icon to the proper position. If your Android device`s screen turns off faster than you like, you can increase the time it will take to timeout when idle.
A doorstop (also door stopper, door stop or door wedge) is an object or device used to hold a door open or closed, or to prevent a door from opening too widely. The same word is used to refer to a thin slat built inside a door frame to prevent a door from swinging through when closed.
From an OCD standpoint, to be triggered is to experience something in a situation or an environment that causes you to have an intrusive thought, image, or urge, or reminds you of a previous one. Essentially, a trigger is anything that leads to an OCD obsession.
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.
Misalignment. A door can become misaligned as a result of loose screws at the top and can mean that it will drop or not hang properly. A misaligned door will not fit into the frame correctly or open and close properly. This can cause draughts and provide an opportunity for intruders to gain access to your home.
Spring Bolt – A spring latch is a bolt held in place by a spring clip. The spring is compressed to unlock the bolt, and when released, it snaps into a locked position. This type of door generally locks automatically when closed.
In most vehicles, the body control module has the ability to control the lights, the horn, the alarm, the door locks, the windows, the climate control system and most of the other circuits.
The BCM communicates with other on-board computers via the car`s vehicle bus, and its main application is controlling load drivers – actuating relays that in turn perform actions in the vehicle such as locking the doors, flashing the turn signals (in older cars), or dimming the interior lighting.
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.
Yes. The locking runs off the battery power. If battery is dead it won`t have power to run the lock .
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.
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.

A door lock relay is an electromagnetic switch that uses very little electric power to turn on a bigger current on and off. The central part of a relay is a wire coil that turns into a magnet when current passes through it.

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.

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.

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.

Door unlocked alarm, no power window or door lock on driver door only, interior light comes on with L turn signa
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.

Key will lock doors and trunk, but not unlock doors on 2004 BMW 645Ci
ANSWER : Hi there. The first thing I would do is try another key to see if you get the same results from the key control. If the separate key works, then it is the key that is the problem.

If not, then I usually start by reprogramming the receiver module first. If that does not help, then the module may need to be replaced.
