Only, not the least bothered by the car owner's devices. Agus Fauzi, an owner of Innova Kijang car, is one of them. "The door can be locked, but it's hard to reopen," he said, Wednesday, June 8, 2011.
In fact, said Agus, he has brought his car to the garage door specialist. However, the results were nil. "The first key to open the lid, but the lapse of two days the same problems over and over," he said.
Then what is the true cause of problems in central lock in car belonging to Agus is? "If you look at the symptoms, and improved recurring still, there are three possible causes," said Ujang Sugiarto, central lock and door specialist Two Son, Cempaka White, Central Jakarta, Thursday, June 9, 2011.
What causes it? How do I fix this? Ujang following explanation:
A. Drive motor wear
Although the lifetime of these devices are relatively long or relatively durable, the lack of good care can cause rapid wear. Some cases show, the driving force that has worn out due to age or treatment errors made the door difficult to open.
"It's easier when the lock. Because the locking process takes less energy, "said Ujang.
When the motor is not functioning normally, like it or not you have to replace them with new ones. However, previous condition of the device make sure it is really worn out or because of other factors.
The trick, use a pen test to see whether or not the flow of electricity in the motor. If still unsure, disconnect the wires from the motor while it and other sambunglah with a longer cable directly to the battery.
Then, by remote control, open-close the lock. "If the movement is fast and loud voice means that there are normal and vice versa," said Ujang.
2. Drive gear and the shaft broken arm
When the motor was still normal central lock, turn your attention to the drive gear and shaft drive arm lock system. Observe whether the tooth is still strong enough to move the locking system consisting of a wire rod.
If the tooth was still in good condition, suspicion should you switch to the arm or shaft drive. Move or drag a weak stem that could cause the process to unlock the drag.
"In other terms, the central lock is opened after the door is locked it is difficult," said Ujang.
About the two devices that cause damage, Ujang called because of their age but also because of treatment errors. Often uncapped central lock when unnecessary can lead to damage.
3. Concussion on the door
Other causes of central lock is difficult to open because the door at which the motor experienced the crunch well placed because of a collision or other factors. Conflicts that makes changing gear position and the arm bent rod.
Although the rate of change was just a little, quite a large influence on the movement of central lock system.
4. Accumulate dirt and wear wires
However, most often, gear and shaft arm drag because it's never been lubricated. "Especially when a lot of dust or dirt that enter into interposed between the door and door trim," said Ujang.
Therefore, he recommends that car owners often clean the central lock system and interposed between the door and trim at least six months. In addition to cleaning, as well melumasinya.
In addition, check that there are a variety of cable in the central lock system. Because, along with the accumulated dirt and damp conditions in between the door and trim wiring, electrical systems quickly worn or brittle.
Improper connection or there is some broken cable strands enough to affect the central lock system work.
