OnTriggerEnter notworking plz help!

This is what i got.
Its for a key that goes into a collider then plays a animation.

using UnityEngine;
using System.Collections;
public class Keyandlock : MonoBehaviour
{

void OnTriggErenter(Collider other) 
{
	if (other.gameObject.tag == "Key") 
	{
		Debug.Log("Detected");
	}
}

}

Spelling mistake.

void OnTriggerEnter(Collider other) 
{
   if (other.gameObject.tag == "Key") 
   {
      Debug.Log("Detected");
   }
}
