Issue with player position on 3-lane track

Hello everybody,

While making a simple, 3-lane endless runner game (like Temple Run and Subway Surfer), I've encountered an issue I can't seem to fix.

When moving the player between the 3 lanes the position seems to mess up randomly. Obviously it's not random, but I can't seem to find the problem.

Here is my code:

 void Update()
     {
         GetComponent<Rigidbody>().velocity = new Vector3(horizVel, 0, 8);
 
         if ((Input.GetKeyDown(moveL)) && (playerPosition != 1) && (controlLocked == false)) //move left, if possible
         {
             controlLocked = true;
             horizVel = -4;
             StartCoroutine(NoMovement());
             playerPosition--;
         }
         else if ((Input.GetKeyDown(moveR)) && (playerPosition != 3) && (controlLocked == false)) //move right, if possible
         {
             controlLocked = true;
             horizVel = 4;
             StartCoroutine(NoMovement());
             playerPosition++;
         }
     }
 
     IEnumerator NoMovement()
     {
         yield return new WaitForSeconds(0.25f);
         horizVel = 0;
         controlLocked = false;
     }

Here are two screenshot to clearly show what I mean:
