How do I troubleshoot my Toyota key fob?

My mom is flying in to visit me. Before I have to pick her up at the airport, I wanted to go buy some flowers to give her. I headed out the door and pressed the unlock button on my car key fob, but it didn’t work. I tried changing the battery, but that didn’t fix the issue either. How can I fix a Toyota key fob?

That’s very sweet of you to buy flowers for your mom! Generally, when a key fob is not working, the battery is the problem. Since replacing it didn’t work, the issue is likely more complicated.

To repair a Toyota key fob, start by disassembling the remote and looking for potential internal damage. Here’s how:

  • Step 1: Take apart the fob. To do so, locate the small metal button above the physical key on your fob. Press the button to take out the physical key. Insert a flathead screwdriver into the slot where the physical key used to be. Then, gently pry open the fob.

  • Step 2: Look for a green circuit board. Take it out of the fob case very carefully and set it aside.

  • Step 3: Make sure the battery is the right type and was installed correctly. Note that there is a chance the new battery is faulty.

  • Step 4: Look for any misaligned buttons and make adjustments if necessary. Also, look for broken internal pieces of the fob.

  • Step 4: Try using the remote again after reassembling it.

Keep in mind if your fob isn’t working—or you spotted broken pieces inside the remote—this could be an electrical issue with the circuit board or another issue you can’t repair yourself.

Conversely, your vehicle could have forgotten your fob. If so, you need to reprogram the remote. If you don’t know how, take it to a Toyota service technician for help.

In some cases, replacing the car remote is cheaper than repairing it. So weigh the cost of repair versus replacement before making a decision.

Why Isn’t My Toyota Key Fob Working Properly?

Your Toyota key fob is designed to make using your favorite vehicle easier, which is why we want to provide service and support for when it stops working correctly. Here are a few of the common issues that might be affecting your key fob, and how they can be fixed.

  • The Battery is Low: If your key fob is unresponsive or taking a long time to function, the most common culprit is the battery. It’s important to pay attention to low battery warnings, so you can get replacements before they’re needed.
  • The Range is Too Far: One reason your vehicle may not be responding to the key’s commands is that you’re out of range. Range may also be shortened by obstacles disrupting the signal between your key and car. Move closer to the vehicle and try the command again before considering other causes.   
  • The Car Battery is Dead: The battery on the fob is one of the most common issues for lack of response, but your fob needs something to communicate with inside the vehicle. If the car battery is low or dead, it won’t be able to follow the fob’s command.
  • The Fob is Damaged: Our Toyota parts and keys are designed for regular use, but accidents happen. Inspect the fob for damage, especially around the receiver, before bringing it in for service.
