Lexus key fobs are known for their sleek design and advanced technology. However, their compact build can make accessing the internal components seem tricky. But don’t worry! With a little guidance, you can easily open your Lexus key fob using a simple coin.

Understanding Your Lexus Key Fob

Before attempting to open your Lexus key fob, it’s essential to understand its basic components and how they function.

A typical Lexus key fob consists of two main parts:

• The main body: Houses the electronic components, battery, and in some cases, a valet key.
• The physical key: A traditional metal key blade that can be detached and used for manual door unlocking or ignition in emergencies.

Keep in mind that Lexus has released various key fob designs over the years. While the general principles remain similar, the exact location of the release button or mechanism might differ slightly depending on your Lexus model and year.

How to Open a Lexus Key Fob with a Coin: Step-by-Step

Follow these simple steps to open your Lexus key fob safely and effectively:

1. Locate the release button or slot: Carefully examine the back or side of your Lexus key fob. Look for a small button or a narrow slot marked with a key symbol. This is the release mechanism for the physical key or battery compartment.
2. Select a suitable coin: A US quarter or a similar-sized coin works best for this task. Make sure the coin is clean and free from debris that could scratch your key fob.
3. Insert and twist the coin: Gently insert the edge of the coin into the release slot or apply firm but gentle pressure on the release button.
4. Separate the fob halves: While applying pressure with the coin, carefully separate the two halves of the key fob. Depending on your Lexus model, the fob might split completely, or a small compartment cover may pop open, revealing the battery or the physical key.

5. Remove the battery or key: If you’re replacing the battery, carefully remove the old one and note its orientation. Insert the new battery, ensuring it matches the + and – markings. If you’re accessing the physical key, gently pull it out from its slot.

Tips and Precautions:

• Apply gentle pressure: Avoid using excessive force when opening the key fob to prevent damage to the casing or internal components.
• Work over a clean surface: This will prevent small parts like the battery or physical key from rolling away and getting lost.
• Note the battery orientation: Before replacing the battery, take note of its positive (+) and negative (–) terminals’ position to install the new battery correctly.
• Consult your owner’s manual: If you have difficulty opening your specific Lexus key fob model, refer to the owner’s manual for model-specific instructions.
