Toyota Key Fobs — Everything You Need To Know

Toyotas are one of the most reliable makes on the market. However, that doesn’t mean your Toyota key fob will last forever. Need to get a replacement but aren’t sure how? Check out this Toyota key fob guide for everything you need to know. After teaching you about your keyless entry system, we’ll reveal where to get new Toyota keys, how to program them, their price, and more.

What Is Toyota Keyless Entry?

Older key fobs required you to press a button on the remote to trigger the door locks. With Toyota keyless entry, however, your key fob can stay right in your pocket. All you have to do is walk up to your car and press a button on the door. The transponder locks/unlocks the doors to give you instant access! Check Price on Amazon

What Is the Toyota Smart Key?

The newer Toyota Smart Key is even more innovative. In addition to letting you open your doors at the touch of a button, it lets you start your engine without having to pull out your remote. Simply push the brake and press the “Start/Stop” button to activate the ignition. Check Price on Amazon These types of devices are available for Toyota models such as:
  • 4Runner
  • Yaris
  • Yaris iA
  • 86
  • Avalon
  • Echo
  • FJ Cruiser
  • Highlander

  • MR2
  • Sequoia
  • Sienna
  • C-HR
  • Camry
  • Celica
  • Corolla
  • Tundra
  • Venza
  • Prius
  • RAV4

Can I Lock My Toyota Key Fob in the Car?

Some people worry about locking their remotes in their vehicles. Fortunately, Toyota has a safety system in place that makes this mistake impossible. As long as your remote is inside of the vehicle, it will remain in “unlock” mode. You won’t ever have to purchase and program a new remote because you locked yourself out of your Toyota car. Check Price on Amazon

How Do I Change the Battery in My Toyota Key Fob?

If your Toyota key fob doesn’t open your doors, it may need a new battery. The good news is that battery replacement is easy enough. To start, open the key case, lift the circuit board, and account for what kind of battery the fob is currently using. In most cases, the standard key fob battery model is a CR2032. Working with something different? Go to a website like Amazon and use its keyword search to find batteries compatible with your model. Once you have the right key fob battery, swap it out with the old battery. Insert the circuit board back on top and close the case. Then, test the battery by seeing if the fob will open your door, start your ignition, etc. Check Price on Amazon

How Do I Get a New Toyota Key Fob?

If a replacement battery doesn’t work for your ignition, you might be wondering how to get an entirely new Toyota fob. This information will also be useful for drivers who want to get spare keys for their family/friends. One option you have is going to your dealer. These providers are reputable and sell OEM fobs that are compatible with your Toyota vehicle. Call ahead to check the price and verify that they have the device you want in stock. However, dealerships try to make as much money off key fob sales as possible. We recommend you shop online to score a better price. Now, that doesn’t necessarily mean you should go to advanced automotive dealer websites. These sites make the shopping process easy through quick links and close search/search by keyword. But they tend to be just as expensive as in-person dealerships. Your best bet is to go through a reputable third-party reseller. Shopping is just as easy thanks to a wide range of products and the ability to search by filters. The best part is that you’ll save on price and enjoy shipping right to your home address.

Should I Go OEM or Aftermarket?

One important tip to keep in mind is to look for Toyota OEM products rather than aftermarket products. Aftermarket products tend to come at a lower price, but because they don’t come from the original manufacturer, there’s no guarantee they’ll be compatible with your vehicle. Plus, dealers won’t service parts that weren’t purchased from the original manufacturer. So if you run into trouble programming an aftermarket device, you’ll be on your own.

How Much Does It Cost to Replace a Toyota Key Fob?

Dealers tend to charge a couple of hundred dollars for new Toyota keys. The price might be higher depending on what vehicle models you have, whether you need a programming service, etc. If you order from a quality site, you’ll get much better sales. We’ve seen Toyota keyless remote sales as low as $100 or less. You may have to pay an extra cost to ship it, but the price will still be much more affordable than dealership sales.

Can You Program a Toyota Key Fob Yourself?

Yes! To perform the programming yourself, you will need to follow instructions that will vary depending on which Toyota remote and vehicle you have. The reseller’s customer service team will provide you with these instructions via your account page. If you get stuck, don’t hesitate to contact a rep as they’re usually more than willing to help. Don’t want to do the programming yourself? You can go to your Toyota dealership and use their reprogramming service. They might do it for free if you buy from them or are a regular customer. However, they might charge up to $100 for the service. Contact your dealer for exact pricing. Requesting service from your dealer can be annoying as you have to wait for regular business hours for them to open. However, getting your replacement programmed by a pro can take away a lot of stress. Plus, you might have to go to a Toyota dealer anyway to have them cut the emergency blade for your replacement key.

Toyota Key Fob — The Bottom Line

Whether you have a Corolla, Prius, or something in between, getting a replacement Toyota key fob is easy. Feel free to keep this guide open this guide as you replace your Toyota key. We recommend that you shop online to find the best sales and save. We recommend doing the programming yourself to connect your devices with your vehicles. If you run into problems, call the reseller’s service team or visit your dealer!
