A smart key is the type of key your 2005 Lexus GS uses. It contains a programmed transponder chip that communicates with your vehicle's immobilizer system to authorize the engine to start. It also has 4 buttons for remote lock, unlock, and other functions. Without proper programming, even a perfectly cut key will be rejected by your Lexus security system. We program everything on site so your new key works exactly like the original.

Q: How long does the dealer process take for Lexus key replacement?

Longer than most Lexus owners expect. Once the fob arrives and you get an appointment, the actual programming takes about an hour in the bay. But getting to that point is the problem. One 2024 RX350 owner waited five months for a notification through the Lexus app that their second key was ready, then had to wait two more weeks for a programming appointment. Some dealers can only order one smart key per VIN per day for RX and NX models, stretching wait times further. With EZ Car Keyz, the job is done in one visit, usually under an hour, right at your location.

Q: What is the FCC ID for the 2005 Lexus GS key?

The FCC ID is HYQ14AAB, 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. Lexus dealers verify every key by FCC ID before they will touch it, and they will refuse to program a fob that does not match. Having this number ready when you call speeds up the process.

Q: What areas do you cover?

We cover all of Simi Valley, close to Simi Valley Cultural Arts Center and surrounding communities. Our mobile service comes directly to your location whether you are at home, at work, in a parking lot, or on the side of the road. Lexus owners in our area do not need to arrange a tow or sit in a dealer waiting room. Lexus dealers will not program fobs you bought elsewhere and insist on supplying their own parts at dealer pricing. We bring the shop to you with all the tools and key blanks needed for your Lexus on board.

2005 Lexus GS Smart key Replacement - Fast, Affordable & Professional

Here's what you're actually paying for when you get a 2005 Lexus GS key. Three things. The physical fob or key blank with the correct blade and button configuration. The precision cut on the emergency blade. And the transponder programming so the car's smart ECU accepts the new key. The dealer charges 581 for those three things. I charge around 315.

A customer staying at a resort in Simi Valley had her only Lexus fob die during a trip. Push-to-start wouldn't respond and the emergency blade wouldn't trigger the backup start on her model. The dealer said to tow it in and they could fit her in the next afternoon. 581 plus the tow. She was supposed to check out in the morning. She found me online and called.

I met her at the resort that evening. Her smart key uses Lexus's proximity system. I connected my VVDI Key Tool to OBD and generated a new fob matched to her smart ECU. Her fob, FCC ID HYQ14AAB, has 4 buttons including lock, unlock, and hatch.

The fob and chip cost me about $50. The blade is cut in the van. The programming takes about 30 minutes through OBD. Her total was 315. She checked out on time the next morning.

“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”

Lexus GS Mobile Service Questions

Your key replacement cost breakdown

Do I have to go to the Lexus dealer to get a replacement key?▼

No. A qualified mobile locksmith can cut and program a smart key for your 2005 Lexus GS right where the vehicle sits. Lexus owners often assume the dealer is the only option, but that is not the case for the vast majority of models. The dealer route means scheduling an appointment, towing if you have no working key, and sometimes waiting weeks for the fob to arrive. During 2022 to 2024, NX and RX owners reported getting only one key at delivery and waiting three to six months for the second.
