Maintenance of cam locks
First of all, experienced carpenters and locksmiths are supposed to be hired to install Cam locks
. At the same time, according to the product manual, drilling holes as preparation for installing the latch plate, the strike plate, etc.
It is necessary to ensure accuracy of all the positions of holes, and the whole installation process needs to be taken under instructions of the product manual. After installation, if the cam lock

is even stuck, any of the locksmith, the local retailer, the lock manufacturer's technical department and after-sales department is supposed to be consulted to offer professional advice and solutions to solve the problem.
It is not recommended to add oil to the lock cylinder. If the key can not open the lock
smoothly, a little powder of pencil lead can be added to the keyhole. In daily life, lubricant are often added to the keyhole when the lock
is jammed. However, by doing so, the lock
can be opened smoothly in a short time, whereas the lock
will be jammed again due to a thick layer of dust accumulating caused by lubricant. As a result, the lock

more durable and attractive.
Moreover, the quality of the lock
can be measured by the quality of the coating. The high-quality lock usually goes through electroplating process and has the smooth and bright surface. Meanwhile, its coating has great uniformity of thickness without blisters, signs of rust or oxidation.
The surface treatment of the lock
is not only for the great appearance but also is related to the quality and the operation life of the lock
. Therefore, high-quality locks are always with qualified coatings.
The quality of the lock
can almost be measured by the quality and performance of the lock cylinder. After installing the lock, the lock cylinder becomes the only part of the lock
which can be seen. The cylinder can be defined as the first fence guard against incursion. Thus, measuring the quality and property of the lock cylinder should be the first indicator for people selecting locks.
