Key Points Explained:

• "3 Buttons" / "Blade: No" / "Circuit Board: No" / "Battery: No": This confirms the product is just a plastic shell with three blank buttons. It does not include a metal key blade to cut for your car, the internal electronic circuit board, or a battery. You must transfer these from your old key.

• "Best replacement for a key with broken buttons or worn key case": This is the exact purpose of this product. If your current key's buttons are broken, the case is cracked, or the finish is worn off, but the electronics still work, this shell will fix it.

• "Not a remote... no interior unit inside": A very important warning. You cannot program this to your car because there is nothing inside to program. It's a physical case only.

• Compatibility: It will only fit the remote key fobs for the listed Toyota/Lexus models (IS200, GS300, RX300, LS400) if your current key looks identical to the one in the product pictures. There were often slight variations, so a visual comparison is critical.

Is This Compatible With Your Car/Key?

Yes, but ONLY if both of these conditions are met:

1. Your Car Model: Your car is one of the listed models (Lexus IS200, GS300, RX300, LS400).

2. Your Key's Appearance: Your current, broken key fob is physically identical in shape, size, and button layout to the one shown in the product pictures.

How to Check Compatibility:

1. Find your current key fob.

2. Carefully compare it to every picture of the product listing.

3. Check the button shape, the curvature of the case, the location of the key ring loop, and the Lexus logo placement. They must match exactly.
