Why Did My Key Fob Fall Apart?

Before we dive into solutions, it’s helpful to understand why your key fob might have come apart in the first place. Here are a few common culprits:

Wear and tear: Over time, the plastic casing of your key fob can become brittle, especially with repeated drops and daily use.
Battery corrosion: Leaking battery acid can damage the internal components and weaken the casing.
Impact damage: Dropping your key fob on a hard surface can crack the casing or dislodge internal components.

Fixing a Broken Key Fob: Step-by-Step Guide

Now, let’s get down to fixing your key fob. Here’s a step-by-step guide:

Assess the damage: Carefully examine your key fob for cracks, broken parts, or loose components.
Replace the battery: If you suspect battery corrosion, carefully remove the old battery and clean any residue with a cotton swab and rubbing alcohol. Insert a new battery, ensuring it’s correctly positioned.
Reassemble the key fob: Align the two halves of the casing and gently press them together until you hear a click. Make sure all buttons and the key blade are properly aligned.
Test the key fob: Try locking and unlocking your car doors using the key fob. If it doesn’t work, try reprogramming it.

Reprogramming Your Lexus GS300 Key Fob

Sometimes, reassembling your key fob isn’t enough. You might need to reprogram it to your car. Here’s how:

Get in your car and close all doors.
Insert the key into the ignition and turn it to the “ON” position (do not start the engine).
Within 5 seconds, press and release the lock button on your key fob five times.
Remove the key from the ignition.
Simultaneously press and hold the lock and unlock buttons on the key fob for at least one second.
Release both buttons when the car’s lights flash twice, indicating successful programming.

Preventing Future Key Fob Issues

Nobody wants to deal with a broken key fob. Here are a few preventative measures:

Use a protective case: A silicone or leather key fob cover can protect it from drops and impacts.
Avoid exposing your key fob to extreme temperatures: Extreme heat or cold can damage the battery and internal components.
Inspect your key fob regularly: Check for signs of wear and tear, battery corrosion, or loose parts.
