How to remove the key locking insert?

Key locking insert is a type of fastener used to connect two parts, usually made of metal. In some cases, it is necessary to remove the key locking insert for replacement parts or repairs. But removing key locking insert can be difficult, especially if it’s stuck or rusted. This article is intended to explain how to remove a key locking insert and also explore some useful tips for removing key locking insert.

1. Use pliers

Some key locking insert are very easy to remove, requiring only a pair of pliers. At this point, hold the latch sleeve tightly with pliers and turn it counterclockwise to remove it. Be careful to make sure the pliers are tight enough to avoid damaging the latch nut or the tool.

2. Use a wrench

This method works on stuck or rusted latch nuts. Select the correct size wrench, then place it on top of the latch nut and turn the wrench counterclockwise until the latch nut starts to move. If the key locking insert is not loose, do not force it to turn as this may cause more damage.

3. Use lubricant

If the latch bushing is rusted or stuck, you can try using lubricant. The lubricant can penetrate into the latch bushing and reduce friction, making the disassembly process easier. It is usually recommended to use petroleum or silicone lubricants. After applying the lubricant, wait a few minutes for it to lubricate, then use a wrench or pliers to remove the latch bushing.

4. Heating

When the latch nut is locked and cannot be removed, you can try heating it. Heating expands the latch sleeve and reduces the area exposed to the outside environment. Water, sand or a torch can be used for heating, but please be careful not to use an open flame or high-temperature appliance to avoid damaging the latch nut or tool. Wait for the latch bushing to cool before turning counterclockwise.

5. Use disassembly tools

If none of the above tips work, you can try using a removal tool. Depending on the size and shape of the latch bushing, different types of removal tools may be required. These tools are usually specifically designed for removing latch thread inserts. Please use according to the instructions for use and follow safe operating procedures.

All in all, removing the latch nut can be a challenge. But with the right tools and techniques, the process can be made easy. If the removal process is too difficult or you never succeed, consider asking an appliance repairman for help.
