How to change the larva in the castle

The larva is part of the cylinder lock mechanism in which the key is inserted while unlocking the door. When you break down the castle, buy a whole new mechanism is not necessary. It is enough to replace it with a larva, which can be bought together with keys in a specialized store or on the market. The lock at the same time to shoot with the door is not needed, but for all manipulations with him 15-20 minutes. How to do this work, you will learn from today's material.

To replace the mechanism, the roulette and screwdriver will be required. Initially, you need to remove the old larch and measure its length, width and diameter, to later buy a new mechanism suitable in size. To dismantle the larva, it is necessary to unscrew the locking bolt, which is on the edge of the door. After that, the key should be transferred to the open position. Now, by clicking on the larva from the outside, you can easily remove it from the castle.

With a broken core mechanism or stuck in it, it will not be able to remove the key to remove the larch. Then you need to use a drill with a 10 mm drill and drill a castle core. After such an operation, the larva will easily be removed.

Choosing a new larva in the store, except for sizes, it is worth paying attention to its color and design. Not bad if the visible part of the new core will coincide with the shade with the door fittings. As for the design of the larvae, it can have two key holes, or one when locking the door from the inside to the "turntable". Decide which core device will be optimal for you.

There is no cheap larvae to buy. They are easily wedged, since the material of their manufacture is too soft, like brass, and the lining is quite weak.

Installation of a new larvae is made in reverse order. It is inserted into the lock hole, the fist of the mechanism turns the new key into the closed position, and the fastening bolt turns into its place.
