Scion Key Fobs – Everything You Need to Know

Many owners of Scion vehicles like using keyless entry to get into their cars. These systems are fast, convenient, secure, and save you time, all at an affordable price.

The Scion range of vehicles has been discontinued. However, it’s still possible to buy a new or replacement Scion entry remote in 2021 at a good price if you know where to search for them.

This page will tell you more information about the Scion keyless entry systems available. Read to learn about the pros/cons, get answers to many frequently asked customer questions, and more.

Types of Scion Key Fobs

The types of Scion key fob available in 2021 depends on the particular model of Scion car that you own:

FR-S Remotes

This remote has four buttons: unlock, lock, open trunk, and panic alarm. It consists of a hidden metal blade that you can use to start the car’s ignition in an emergency. You must program the fob before using it.

iA Remotes

Like the FR-S remotes, this remote has four buttons: unlock, lock, open trunk, and panic alarm. It has a separate emergency blade that slots inside the remote. You can use it for keyless push-to-start ignition vehicles. It also requires professional electronics programming before use.

iM Remotes

The iM remote has three buttons: lock, unlock, and panic alarm. The key flips up from the side of the remote by pushing a button on the front. You can use it for vehicles with a key slot on the door and a standard ignition system. As with the other remotes, it requires professional programming before it will work with your vehicle.

tC Remotes

The tC remote has three buttons: lock, unlock, and panic alarm. It has an emergency blade you can insert in the door and slotted back inside after use. Drivers use this style with push-to-start ignition systems. It will require professional electronics programming before use.

xB Remotes

For earlier xB models, the remote does not contain a key and only has a locking and an unlocking button. However, self-programming is possible for this type.

For later xB models, the remote has three buttons (locking, unlocking, and panic alarm) as well as a metal blade for use in the ignition, but it does require professional programming in advance of use.

Features of Scion Keyless Entry Remotes

Panic Alarm

Most remotes have a panic alarm that allows you to address nearby pedestrians and drivers if you are in distress.

Open Trunk

Most remotes have a button to open the trunk, so you can access your car’s trunk without unlocking the whole vehicle.

Emergency Key

If your fob runs out of battery, don’t worry. Most versions come with an emergency key so you can still access your vehicle without any difficulty.

Pros

Convenient

Using keyless entry systems is much more convenient than standard car keys, as you can open your car door without having to search your bag. You also don’t have to be right up close to the door before you can open it, saving you time.

Secure

The keyless system only works if you are relatively close to the vehicle, so there’s relatively little threat of a thief accessing your car. You won’t have to think twice about security with a keyless entry system.

Cons

Price

While the cost of a remote isn’t that high, you also have to account for the price of programming the remote and have a locksmith cut the blade.

Frequently Asked Questions

How Much Is a Replacement Scion Key?

The price of a replacement Scion key depends on the particular model you own, its year, and the particular functionality you want from the remote.

Don’t forget that before you can use the entry remote, you will have to program it through a professional programming service, which could incur additional fees.

To use the emergency key in the car door, you’ll have to go to an auto locksmith service, which is also likely to incur an additional fee.

Therefore, to work out the price of your replacement key, you’ll need to account for the price of the fob itself as well as the service fees for preparing it for your vehicle. The overall cost can be as much as twice the initial cost of the fob.

How Do You Program a Scion Key Fob?

Most Scion fobs require professional programming before you can use them on your vehicle. You can visit an auto locksmith shop or contact your local Toyota dealership.

You will likely have to pay an extra fee for the cost of programming the key fob in addition to the cost of buying it from the shop.

If you buy the fob from an after-market shopping site, you may be unable to get programming services from a Toyota dealership, as they could refuse to program a key fob that is not certified by Toyota Inc copyright.

Can You Get Replacement Key Fobs?

It might be hard to search for the right Scion products when shopping for them, as Toyota no longer makes the Scion models of car. However, there are still several new and used remotes you can purchase.

Toyota manufactures Scion keys, but they are often close to twice the price as those from others. However, beware that a dealer could be unwilling to program third-party remotes due to copyright issues with others.

Can a Locksmith Replace a Key Fob?

Since Toyota discontinued the Scion make of cars, some locksmiths no longer supply Scion remotes. As such, you should contact or email your locksmith in advance to check that they are able to help you as a Scion customer.

Follow up with an email to your nearest Toyota dealership if your local locksmith cannot assist in time. They’ll let you view the products they have available to a Scion customer and give you information on the costs involved.

Verdict: Should You Buy a Scion Key Fob?

A Scion key fob is a great, convenient way to access your vehicle door without using a key, saving you time and effort.

However, the discontinuation of Scion cars means that there are fewer Scion remotes available. If you’re unable to find the right model online, follow up with an email to your local Toyota dealership to see if they can help you as a Scion customer.
