Question 1

My key broke in the ignition. Can you get it out?

Accepted Answer

Yes. On Lexus models with a traditional ignition cylinder, we can extract the broken piece without damaging the lock. Once it is out, we pull the original key code from your door lock or vehicle records and cut a factory spec blade so you are not reusing a worn key. On push-button Lexus models, the emergency blade can snap in the door lock if forced. We remove the broken piece, decode the lock, and cut a new blade that matches exactly.

Question 2

What is a remote head key?

Accepted Answer

A remote head key is the type of key your 2005 Lexus IS uses. It contains a programmed chip that communicates with your vehicle's immobilizer system to verify it is an authorized key before the engine will start. It also has 3 buttons for remote lock, unlock, and other functions. When a key breaks, the chip inside may still be functional, but the physical damage usually means a full replacement is the safest option to avoid getting stranded again.

Question 3

My Lexus says key not detected. What do I do?

Accepted Answer

First, try holding the fob directly against the start button and pressing. Your Lexus can power the transponder chip like an RFID tag even when the fob battery is completely dead, so this works indefinitely as long as the chip is healthy. If that gets the car started, replace the battery with a fresh name brand CR1616. If holding the fob to the button does not work, the issue may be the key itself or the vehicle's reception module. Some GX460 owners found that a software configuration setting had disabled smart key reception, and simply turning it back on fixed the problem without replacing anything.

Question 4

What is the FCC ID for the 2005 Lexus IS key?

Accepted Answer

The FCC ID is HYQ1512V. This is the identifier printed on the back of your key fob that tells us exactly which key your vehicle requires. It ensures we match the correct blank, chip frequency, and remote protocol so the key programs correctly on the first attempt. If your existing key is damaged and you cannot read the FCC ID on the back, give us your VIN and we can look it up to confirm the right replacement.

Question 5

Is all-keys-lost more expensive than a regular replacement?

Accepted Answer

Yes. When you have at least one working key, adding a spare is a quick programming job. When every key is lost, the Lexus smart key computer needs to be fully reset and new keys programmed from scratch. An LS430 owner reported the dealer quoting $1,500 for all-keys-lost versus a few hundred for a spare key when a working key was present. Locksmiths in the same area quoted $350 to $600 for the same AKL job. The gap between add-a-key and all-keys-lost is real, which is why we always recommend getting a spare made while you still have a working key.
