G28 Car Keys can get stuck for a variety of reasons. Most often, the issue lies in the latch mechanism itself.
The good news is that the majority of these problems can be resolved with a few simple tactics. Find out how!
Check the Key
Over time, the tumblers within the lock for your car door could become clogged with dirt and rust. This can prevent the lock from opening or closing when you insert your key fob or switch the key in the ignition. It can also cause the mechanism to become blocked. If this happens, you may need to remove the door handle and then access the lock mechanism to free it. This is a DIY project that can be completed at home.
There are a variety of reasons your door latch may be stuck. It could be due to a physical obstruction in the mechanism of the latch or an electrical issue with your key fob or door lock solenoid. Another possibility is that someone knocked the latch into a locked position while the door was opened.
If the issue is with your key, try putting it out and back into the lock several times to see whether the tumblers move freely. This will usually reset the lock.
You could also try using a lock de-icer to melt the ice and help you open the door. If you're struggling, you can spray some multi-purpose lubricant in the door lock mechanism. Make sure you turn off the lock before you begin. In case you don't, you could cause damage to the latch mechanism.
If the lock is properly lubricated, you should be able to open it with the door handle. If you cannot, there could be a problem with the latch mechanism, and you'll have to replace it.
If a latch is locked and you cannot open it, you can make use of a screwdriver to manually push it up to the final unlocked position. To do this first, pull the interior and then the exterior handle of the car. Use a screwdriver and apply pressure to the left leg of the latch to allow it to be pushed upwards to the final unlocked location. Repeat this process on the right side of the latch to complete the reset. Once the latch has been unlocked, you can close the door to test it.
Check the Battery
The car door lock works by sending electronic signals to the solenoid in each door. This solenoid then translates these signals into mechanical action. In this instance, turning a steel bar that locks the doors. It can be quite frustrating when the doors of your car won't lock or unlock via the key fob, or from inside or outside. Fortunately, it's possible to get the problem fixed without taking your vehicle to mechanic.
The mechanism for locking your door could be jammed. To test this, open up your door and look at the latch mechanism. You'll notice that it has "open" jaws on the other side designed to grab the anchor in the jamb of the door and then turn into a closed position to connect the latch to the anchor. If the latch is shut and it's not able to rotate into the proper position, the latch won't engage the anchor and shut your door.
You can fix the issue by applying WD-40 or a different oil-lubricant to the interior of the door. Utilizing a screwdriver, you can push the latch to the open position. Then, turn it to its normal position. It's a good idea to have a friend or family member help in this process as it can be very difficult to do alone without damaging anything.
Once you've lubricated the latch mechanism, it's important that you don't attempt to force the key in. It is possible to break the key in the lock if you attempt this.
Alternatively, if you're having difficulty locking or unlocking your vehicle using the key fob and have tried all of the steps above, it's best to contact a professional technician for some more advanced diagnostics and repair. They'll pinpoint the root of the issue and provide the best solution for your vehicle and you.
Check the Wiring
A malfunctioning control module could be the reason behind an inoperative door lock inside the car. These modules are responsible for the electric locking and unlocking mechanisms. They connect to the latch and handle through a series of rods that allow them to move upwards and downwards. The system will stop functioning correctly when they are worn out. This is a problem that occurs in older cars.
Other problems can cause the door lock and then become stuck in a locked state, such as dirt or grime that has accumulated on the lock mechanism or a handle that is jammed. Sometimes, a simple lubrication will solve the problem. Penetrating catalysts or WD-40 can be purchased at most home improvement centers, auto supply stores, or online and used to lubricate car door locks via the keyhole.
Examine the wiring and fuses for any problems that may occur if you cannot unlock the door with the button or key inside the car. If the wiring is fine the issue is likely to be with the solenoids of the power lock and actuators.
A professional locksmith can diagnose and repair any problems with the door locks of your car. They can also assist you to install any new features, such as smart keys that will make your car more convenient in the future.
The process for taking off the handle and interior panel varies from car to vehicle however the principle is the same. It is generally necessary to locate and take off all the fasteners holding the handle plate or the panel in place, then gently remove the panels without damaging them. You'll then be able to access the lock actuator and door latch to check what's happening. After removing the panel you can access the latch that is locked using the screwdriver. Position it between the legs of the door latch and then push it upwards until it is locked. After that, you can close the door to test whether the latch has been reset.
Check the Actuator
The door lock actuator like any electrical device can malfunction over time. This can happen for various reasons like corrosion resulting from exposure to water or other contaminants. In addition, the actuator may also become misaligned or damaged due to mechanical stress or over force.
When you can't unlock the doors using the key fob, or even manually activating the switch in the car, this is a common indication that the actuator is malfunctioning. This could be a serious issue, since it indicates that someone is able to lock the car without having the proper keys.
The first step to evaluate the condition of the door lock actuator is to determine whether it is receiving power from the vehicle's central locking system or the power windows control module. Then, you can test the function of the actuator with a multimeter, looking for any unusual or irregular behavior. Finally you can inspect the actuator for indications of wear or damage, and ensure that the linkage isn't blocked or tied up.
It's important to note that the actuator isn't repairable and should be replaced in the event it becomes damaged. You can do this with the help of a professional, but it is important to know that you'll probably need to remove the door panel for accessing the actuator.
Before performing any tests on the door lock actuator, it's always a good idea to put on your safety glasses and read the manual for the vehicle owner's guideline for recommended safety precautions. Also, make sure you're working on a flat surface and have a socket readily available.
To test the actuator, locate the latch in the door, and then locate the hole or gap that it is supposed to be caught in. After that then, place the key or pen into the gap. Then flick/push the object towards the door in an upwards motion. If the door latch is moving then the actuator is likely to be working correctly and the problem is with the remote or key fob.
