Broken or Worn Out Locks
If you are able to turn the key inside the lock of your car's central locking system, but it takes some time to unlock or lock the doors it could be a sign the lock is damaged or worn out. It usually happens because dirt or grime gets trapped in the lock mechanism. To resolve this issue, you need to clean it. To do this, put a cotton swab into the lock and wobble it to draw dirt. Then, you need to lubricate it. Use silicone spray or graphite. You should avoid using oil-based lubricants as they will cause the dirt to accumulate within the lock and may cause it to get worse.
Another issue with a broken lock is that it could be misaligned. The strike plate is where the bolt for the lock goes when you close the doors. It can be misaligned and stop the lock from functioning. The good news is that this problem is fixable by spraying a couple of times of a fluid that lubricates. This will help coax any part to function correctly.
The lock cylinder could be worn out or damaged. The lock cylinder is what secures the door when the key is turned.

The lock cylinder can be replaced to correct this issue. You can purchase the parts online or in a local auto shop. Regularly lubricating the cylinders and other components in your vehicle will decrease the frequency at which they must be replaced. This can also extend the life of your vehicle. If you have a central locking system that isn't working as it should, it could be an issue with the wiring. It could be just as simple as a faulty or loose wire.
Poor Wiring
Central locking is controlled by a series of electrical components and switches that wear out over time. The electrical connectors and switches are delicate, particularly when they are used regularly. It is not uncommon for these to start to fail. When your central locking system suddenly ceases to function, there could be a myriad of causes to the issue, and it's important to seek out an expert to examine the issue before deciding if you should replace the entire system.
One of the most frequent causes of this type of failure is defective wiring. Faulty electrical wiring can cause a number of problems that include frequent circuit breaker trips as well as blowing fuses. It is a good idea prior taking your car to a garage. A simple fuse can help save a considerable amount of time and money.
If you are aware of what to look for, it is easy to spot the signs of defective electrical wiring. A wire that is exposed could cause rust and corrosion. Another common sign is a buzzing sound which occurs when an electrical current is disrupted by loose prongs or some other problem.
The next most common reason for a central locking malfunction is a blown fuse, that could have tripped or simply stopped working. You can determine the cause by looking at the diagram that is usually found on the inside of your fuse lid. You can tell if a fuse is blowing by its middle gap.
If you are unable to locate the fuse you have to replace, it is best to contact Fixter and have a professional come out to your home and replace it for you. You'll save money by avoiding independent garages and dealer prices and be confident that the issue will be dealt with by a trained, certified mechanic.
Faulty Actuator
Modern central locking systems allow drivers to remotely lock or unlock all their vehicle doors with one switch or button on their key fob. This technology is not immune from malfunctions, despite the fact that it provides a lot of convenience. The most frequent issue occurs when the car's door lock actuator does not respond to remote controls or the in-car controls. A malfunctioning actuator could cause the power locks to operate erratically, producing unusual noises or fail to lock altogether.
Door lock actuators are solenoids or reversible motors equipped with gears that control the locking and unlocking of door locks. Like any mechanical component they are subject to wear and tear over time. Extreme temperatures, humidity and environmental contaminants can compromise the functionality of the actuator's internal parts. Over time, this may cause a loss in power, increased resistance and damage to internal components that could cause the failure of the door lock actuator system.
An easy way to determine whether the actuator is in need of repair is to look for clicking or clunking noises during operation. A malfunctioning door lock actuator might also not be able to respond to lock and unlock commands in a timely manner. A slow response could indicate that the internal motor or electrical components are degrading, requiring immediate attention to avoid failure of the central locking system.
While a damaged actuator can often be repaired on-site However, you may need to remove the door in certain cases to access it. It is best to seek out a professional technician for help with this process, as it requires advanced diagnostics and specialized tools.
If you are not able to find a solution for your central locking issues it is likely the problem stems from the key fob itself. Key fobs have tiny batteries that must be replaced regularly to remain operational. A dead or malfunctioning batteries could stop the fobs from transmitting a message to actuators, which can cause them to cease working. Changing the battery should restore the full functionality of your central locking system.
Faulty Switches
Modern central locking systems allow you to unlock and lock all the doors of your vehicle from a single source, whether it's the key fob or switch on the dashboard. This is a far more efficient method than the traditional 'key in lock' system and offers an ease of use that is hard to beat. However the switches and electrical components that control this advanced system are susceptible to wear and tear, and if they fail, it could cause the doors of your car refusing to open or close.
When you press the button on your key fob or the switch in your car, a signal sent to a relay within each door that activates the door's actuator that is responsible for the physical locking or unlocking. These switches are often exposed to extreme driving conditions and may be affected by a variety of problems. If you suspect that the switch is malfunctioning for instance, if it makes an eerie sound or is warm to the touch then it should be replaced as soon as it is possible.
A faulty wiring issue can cause various issues in your central locking system and they are usually more difficult to pinpoint than the issue that is caused by a particular actuator or switch. If your locks in your car aren't working to operate on themselves it could be due to a faulty wire that's being jolted by the door's operation, which causes intermittent electrical power from the relay to reach the actuator.
Keep in mind that a central lock repair service won't fix all of your car's problems however, it can save you time, money and stress in the long haul. If you're experiencing issues with a faulty central locking system, then it's worth booking an appointment with Fixter to ensure that one of our experienced mechanics take a review of the issue and give you a price-effective estimate for any repairs that are required.
