- Check how far the key turns:
- The key should turn ¾ of a turn to unlock.
- If it only turns ¼ of a turn, check if the key is damaged or incorrect.
- If the key turns between ¼ and ¾ of a turn, lubricate the lock with a non-silicone-based lubricant and use compressed air to remove debris.
- If the key turns more than ¾ of a turn or rotates fully, contact AMP LOCK or a locksmith, as the internal mechanism may be damaged.
