Are you in need of a replacement key fob for your 2012 Toyota Corolla? Losing or damaging your car key can be a frustrating experience, but finding a replacement shouldn’t be. This guide will walk you through everything you need to know about replacing your 2012 Toyota Corolla key fob, ensuring you get the right remote for your vehicle and understand the programming process.
When it comes to a 2012 Toyota Corolla keyless entry remote, you have options. While dealerships are an option, aftermarket key fobs offer a cost-effective alternative. This article focuses on aftermarket solutions, providing you with the essential information to make an informed decision.
One crucial point to note for 2012 Toyota Corolla models is the existence of two different key fob types. These remotes look almost identical, but they are not interchangeable. The key difference lies in a small marking on your original key or remote. To ensure compatibility, you need to identify whether your Corolla uses a key fob with a “dot” or a “G” on the back of the key blade or current remote.
Identifying the Correct Key Fob: “Dot” or “G” Chip
For 2012 Toyota Corollas, Toyota issued two types of remote keys. It’s critical to determine which type is compatible with your vehicle.
-
OPTION 1: “Dot” Key Fob
- Look for a small dot on the back of your existing remote or the plastic head of your mechanical key.
- Toyota Part Numbers associated with the “dot” key fob are: 89070-02270, 8907002270.
-
OPTION 2: “G” Key Fob
- Look for the letter “G” on the back of your existing remote or the plastic head of your mechanical key.
- Toyota Part Numbers associated with the “G” key fob are: 89070-02620, 8907002620 (for vehicles with VIN starting with 1 or 2, made in North America) or 89070-12820, 8907012820 (for vehicles with VIN starting with J, made in Japan).
It is essential to verify this detail before purchasing a replacement 2012 Corolla Key Fob to guarantee it will work with your car’s system. Selecting the wrong type will result in incompatibility.
Programming Your 2012 Corolla Key Fob
Once you have the correct replacement key fob, programming is the next step. Aftermarket key fobs for the 2012 Toyota Corolla, like the one described here (Part SKU: RK-TOY-402), require professional programming. This means you will need to visit a local automotive locksmith.
While some online resources or videos might suggest DIY programming methods, these typically only cover programming the button functions (lock, unlock, trunk, panic). These procedures will NOT program the transponder chip that allows you to start your 2012 Corolla’s engine. For full functionality, including starting your car, professional programming is necessary.
Automotive locksmiths specialize in car key and remote programming and are generally more affordable and willing to program aftermarket remotes compared to dealerships. Dealers may sometimes decline to program aftermarket key fobs.
