Tesla model 3 key fob

Types of Tesla Model 3 Key Fob

The Tesla Model 3 key fob is a handheld device used to access and control Tesla vehicles. Though it is a small device, it is powerful and very important to the vehicle. Without it, one cannot access the vehicle, and even if one accesses it, one cannot start the car. The key fob is designed to make access to the vehicle very convenient and, most importantly, secure. It comes in different types, which are:

• Key fob with card access: This key fob allows access to the vehicle by tapping the fob on the driver's door. To enable key fob access, go to Controls > Locks in the car and configure the fob. Key fob with card access doesn't allow Trunk Open Without PIN. To open the trunk, always use the key fob or key card to unlock it first.
• Key fob with phone access: This key fob allows access to the vehicle without physically touching the car. To access the car, have the key fob in the pocket, and the car will sense the fob and unlock it. To enable key fob with phone access, go to Controls > Locks in the car and configure the fob.

Both key fob with card access and key fob with phone access are great access keys, but they have their advantages and disadvantages. While key fob with phone access allows access without physically touching the car, key fob with card access requires tapping the fob on the driver's door to access the vehicle.

To keep the key fob working perfectly, always replace the battery when it runs down. The key fob uses a CR2032 battery.

Specifications and Maintenance of Tesla Model 3 Key Fob

• Battery

  The key fob has a CR2032 battery. It is a 3-volt lithium battery with 20 mm diameter and 32 mm height. The "key" 3 part indicates it is a lithium key, and the 32 means it is 32 mm wide. These batteries are often used in hearing aids, watches, medical devices, and other important devices that require a reliable power source. Since the battery is not rechargeable, regular replacement is required. Typically, a replacement is needed every 2-10 years, depending on usage and storage conditions. When the battery needs replacement, users will notice reduced range or slower response time. Replacing is simple and affordable. Users can do it themselves in minutes. First, remove the two small screws on the back of the fob. Carefully separate the two halves and remove the old battery. Insert the new battery with the correct orientation (+ side up), close the case, and reattach the screws. The whole process takes less than 10 minutes. Be sure to use a battery of the same type and size (CR2032) for proper function and safety.

• Material

  The key fob is made of high-quality materials for durability and style. The exact materials are not publicly disclosed, but it likely contains metals, plastics, and coatings commonly used in electronic devices. The fob's casing is probably made of ABS plastic. This Strong thermoplastic is often used in automotive interiors and key fobs. It offers good impact resistance to protect the internal components from drops or bumps. The buttons may use TPE or TPU. These soft rubbers have excellent elasticity, wear resistance, and chemical resistance. They are often used in automotive parts like key fobs, buttons, and grips that require a soft touch. For the antenna, it is usually a copper or nickel-plated brass wire. This antenna is responsible for sending and receiving signals. The fob also has electronic circuits and components inside. These include signal processors, memory chips, and other important parts needed for high-tech operation. Of course, the exact materials and manufacturing processes used to make the key fob are proprietary to Tesla.

• Size and Weight

  The Tesla Model 3 key fob is a compact and lightweight remote control that allows users to control various vehicle functions. Its small size and low weight make it easy to carry in a wallet, pocket, or purse. While the exact dimensions are not publicly disclosed, the key fob is roughly the same size as other key fobs. Typically, it measures about 4 inches long, 1.5 inches wide, and 0.5 inches thick. The key fob is also very light, weighing approximately 1 ounce. With its small size and light weight, the key fob is very convenient for daily carrying and use.

• Connectivity

  The Tesla Model 3 key fob is a sophisticated device that uses advanced technology to ensure a secure connection between the fob and the vehicle. The key fob uses a low-frequency (LF) signal for short distance operations like locking and unlocking doors. This LF signal is strong and secure, making it difficult for unauthorized users to intercept or duplicate. It is perfect for key fob functions that require a reliable and secure connection between the fob and the vehicle. The key fob also has a high-frequency (HF) signal for long-distance operations like starting the car. This HF signal allows for communication between the fob and the vehicle over longer distances. It's especially useful for functions that need a more extended range, such as remote starting or warming up the car before getting in. By using both LF and HF signals, the Tesla Model 3 key fob ensures smooth and secure communication between the key fob and the car. This dual-signal system improves security, reduces the risk of hacking, and makes it easy for users to control their vehicles from a distance.
