2012 Lexus GX
Fast Key Replacement in Ventura County

Q: How do I know you are not a scam locksmith?

Scam locksmiths are a real problem in the auto key industry. The common pattern is a fake Google listing with a rock bottom price that triples once the tech arrives. They often show up in unmarked vehicles, cannot name the company they work for, and refuse to show identification. EZ Car Keyz has over 100,000 followers across YouTube and TikTok where you can watch us do exactly this work on Lexus and other vehicles. We give you a firm price on the phone, show up in a marked vehicle, and the price does not change.

Q: Will the replacement key work exactly like the original?

Yes. We program the transponder, remote lock and unlock, and all other functions specific to your 2012 Lexus GX smart key. The key is tested on every function before we leave. Lexus owners on forums have reported dealers selling $600 worth of new fobs when the real issue was a software configuration bug that could be fixed in the menu. One GX460 owner was told they needed all new fobs when simply turning the smart key setting back on restored everything. We diagnose before we sell.

Q: What battery does the 2012 Lexus GX key fob use?

The 2012 Lexus GX uses a CR1632 battery. You can pick one up at most auto parts stores or pharmacies for a few dollars. When we make a replacement key, we always install a fresh battery so you are starting with a full charge. If your Lexus is showing key not detected or key battery low, try a fresh name brand battery before assuming the key needs to be replaced. Cheap coin cells are a common cause of intermittent fob issues.

Q: What happens if something goes wrong after you leave?

Every key we make comes with a warranty covering both the hardware and the programming. If the key stops working, you call us and we take care of it. Properly programmed Lexus keys stay registered to the vehicle reliably over years. Most issues owners report after programming turn out to be vehicle software glitches or configuration changes in the car, not the key losing its programming. We stand behind our work and will come back out if there is ever a problem.

2012 Lexus GX Smart key Replacement - Fast, Affordable & Professional

I can usually get to you in Port Hueneme within 30 to 45 minutes. The 2012 Lexus GX key replacement takes 25 to 50 minutes depending on whether you have a working key or it's all-keys-lost. From phone call to engine running, most Lexus jobs wrap up in about an hour to an hour and a half.

A real estate agent called at 8am. She had a showing at 9 and her GX fob had died in the office parking lot in Port Hueneme. Push-to-start wouldn't respond and she had clients arriving in an hour. She couldn't reschedule.

I was at her office lot in 25 minutes. I decoded the lock with my TOY43 Lishi and got inside, then connected through OBD. Her smart key, FCC ID HYQ14ACX, needed a fresh CR1632 battery and a reprogram to clear the communication fault. Total hands-on time was about 20 minutes.

She made her 9am showing and paid 369 total. Dealer would have been 663 plus a tow plus a missed showing worth more than both bills combined.

“Super fast service. About 20 minutes from the call he was already there. He had an authentic replacement on hand and made a spare key for my 2017 Nissan Rogue in about 15 minutes. Great prices, friendly, and very professional.”

“Tim went above and beyond. I struggled all day trying to program a new FOB and nothing worked. Tim helped me patiently, even recommending cheaper options since I was on a tight budget. He eventually came all the way to Ojai late at night and fixed everything.”

“We had one broken key for our Honda Civic and one working key for our Lexus. Tim came out and cut three remote car keys at a great price. All keys worked perfectly. Professional, courteous, and highly recommended.”
