This video involves replacing the lock actuator on a 2006 Toyota Sequoia. The steps should be the same for a 2000-2006 Toyota Tundra. The automatic lock was longer working on the passenger side, which is a clear sign that the actuator needs to be replaced. The part can be purchased online for around 25-30 dollars. Make sure to choose your vehicle make and model, and get either the right or left side. Hope this helps!
