Understanding Your Lexus Key Fob

Your Lexus key fob is more than just a remote; it’s a sophisticated piece of technology. Inside, it houses a transponder chip that communicates with your car’s immobilizer system. This system prevents theft by ensuring only a recognized key can start the engine. But what happens when the battery dies? That’s where the hidden mechanical key comes in handy, allowing you to access your vehicle even without power to the fob.

Locating the Hidden Key Release

Most Lexus key fobs have a small release button or switch. Pressing this will allow you to slide out a hidden mechanical key blade. This key is your backup for situations where the key fob battery fails.

Using the Coin to Access Your Lexus

Once you have the mechanical key, locate the small, often covered, keyhole on the driver’s side door handle. On many Lexus models, this keyhole is concealed behind a small plastic cover that can be pried open using a coin – hence the “lexus key fob use coin to open” search term. Insert the mechanical key and turn to unlock the door manually.

Why a Coin?

The coin acts as a lever to gently pry open the cover without damaging the surrounding paintwork. A flathead screwdriver could work, but a coin is often more readily available and less likely to cause scratches. This clever design keeps the keyhole discreet while ensuring you always have a way to access your vehicle. key fob battery size lexus gx460
