Toyota Venza Door Lock Failure Diagnosis Guide

Having problems with your Toyota Venza’s power door locks? Don’t deal with this hassle any longer. Here is a handy guide to diagnosing the problem. 

Toyota Venza Door Lock Failure Diagnosis Guide

Before you begin to work on your power door locks, it is important to properly troubleshoot the problem. Diving in and tearing apart every door panel when it is just a simple dead battery in the remote is not a good outcome.

All Doors/Many Doors

If all your doors aren’t working or if you have many doors that won’t work, you might have a big problem on your hands. First, check the power door lock button on the door. If that works, then check the key fob. If that doesn’t work and the key fob doesn’t either, bring your Venza to a Toyota certified mechanic. Odds are you have a blown fuse or a much larger electrical issue.

Single Door Won’t Work

If one door won’t lock or unlock, it is probably the door actuator motor or something is off track. Often times, you will hear a buzzing sound for a while until the actuator fails. Here is a typical fix:

  1. Order an OEM replacement part from a Toyota dealership like
  2. Remove the door panel by locating the screws in the armrest and on the door itself.
  3. While you carefully pull the door panel off, look for and unhook an electrical connection that connects the door locks to the locking mechanism.
  4. Peel back the plastic shroud to expose the locking mechanism.
  5. Locate the actuator by comparing the pieces to your replacement part and then swap them out.
  6. Carefully put the door back together.

Key Fob/Remote Lock Fails

If your key fob doesn’t unlock the doors any longer, check the battery inside of it. This is easily done by finding where the pieces adjoin each other. Pop off the back and you will find the battery.

Lastly, if none of these steps fixed your problem, then it is time to take your Venza to a Toyota certified mechanic. While power door locks aren’t necessary to driving your vehicle, they are a nuisance.
