Types of Car Fobs

Before we dive into the process of opening a car fob, it’s essential to understand the different types of car fobs. There are two main types: remote keyless entry (RKE) fobs and proximity key fobs.

RKE fobs are the most common type of car fob. They use radio frequencies to communicate with the car’s computer and allow you to lock and unlock the doors, as well as start the engine. RKE fobs typically have a battery life of around 2-5 years, depending on usage.

Proximity key fobs, on the other hand, use Bluetooth technology to communicate with the car’s computer. They’re often used in newer cars and provide additional features such as remote start and keyless entry. Proximity key fobs typically have a longer battery life than RKE fobs, often lasting around 5-10 years.
