How to Execute a Kimura (Keylock) Submission from Side Control

Kimura submission, also known as the keylock, is a highly effective submission that can be executed from a variety of positions. One such position is side control, which provides ample opportunity to trap an opponent’s arm and apply the submission. In this article, we will explore the key steps involved in executing a kimura submission from side control.

Establishing Side Control

The first step to executing a kimura from side control is to establish side control position. This can be done from a variety of positions, such as mount, guard pass, or takedown. Once in side control, it is important to maintain good control over your opponent’s hips and shoulder, preventing them from escaping or regaining guard.

Trapping the Arm

Once you have established side control, your next step is to trap your opponent’s arm. This can be done by using your near-side arm to control your opponent’s wrist or elbow, while using your far-side arm to slide under their arm and grab their wrist or elbow. This will create a “figure-four” grip on your opponent’s arm, effectively trapping it and setting up the kimura submission.

Applying Pressure

With your opponent’s arm trapped, you can now begin to apply pressure by driving your weight into their shoulder and twisting their arm. To do this, you can use your chest or shoulder to apply pressure to your opponent’s shoulder, while using your trapped arm to pull their wrist or elbow towards their head. This will create a strong, twisting pressure on your opponent’s shoulder and elbow, making it difficult for them to escape or resist the submission.

Finishing the Submission

To finish the kimura submission, you need to continue applying pressure and twisting your opponent’s arm until they either tap out or you hear a loud popping sound. It is important to maintain control over your opponent’s body throughout the submission, as they may attempt to roll or escape.

Common Mistakes

One common mistake when attempting a kimura from side control is to lose control over your opponent’s body. This can happen if you focus too much on the submission and not enough on maintaining control. Another mistake is to apply too much pressure too quickly, which can cause your opponent to resist or escape the submission. It is important to apply pressure gradually and maintain control throughout the submission.

Drilling and Practice

Like any submission, the key to mastering the kimura from side control is to drill and practice it regularly. This can be done with a partner, using light resistance and gradually increasing the intensity as you become more comfortable with the technique. You can also practice the kimura from different positions, such as mount or guard, to further improve your overall grappling skills.


In conclusion, executing a kimura submission from side control is a highly effective technique that can help you control and finish your opponent in a variety of grappling situations. By following the steps outlined in this article, and practicing regularly, you can add this powerful submission to your arsenal and become a more effective grappler.
