2016 Lexus LX
NASTF Certified Key Service in Ventura County

Q: Do I need to tow my car to the dealer if I have no keys?

No. That is the dealer route, not the only route. Lexus dealers require the car to be towed in for all-keys-lost programming because their process is tied to the service bay. One RX350 owner was told by the dealer that the car had to be towed in from two hours away. We bring professional Lexus-specific tools to your location and handle the smart key reset, cutting, and programming right at your vehicle. No tow truck, no flatbed bill, no leaving your car at the dealer overnight.

Q: How long does an all-keys-lost replacement take?

On newer Lexus models with push-button start, the factory security system forces a roughly 16 minute countdown before it will accept new keys. Total on-car time usually runs 20 to 30 minutes once we are connected. Compare that to the dealer route where you are looking at a tow, waiting for a fob to be ordered if it is not in stock, and a service appointment that could be days or weeks out. We handle Lexus all-keys-lost same-day in a single visit, typically under an hour from arrival to handing you a tested key.

Q: What battery does the 2016 Lexus LX key fob use?

The 2016 Lexus LX 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. Pro tip: once you have your new key, pick up a spare battery and keep it in your wallet or glove box. A dead battery is the most common reason Lexus owners think they have a key problem.

Q: Can you make a spare at the same time so I have two keys?

Yes, and we strongly recommend it. Once the security system is open and talking to our tools, adding a second key at the same visit is far cheaper than doing it later from scratch. If you come back for a second key later, we would need to run the full programming session again. Many Lexus owners who go through an all-keys-lost situation learn the hard way and choose to have us program two keys on the spot. The incremental cost for the second key is much lower than a separate visit.

2016 Lexus LX Smart key Replacement - Fast, Affordable & Professional

I got a call from a customer at a Lexus forum meetup near Pleasant Valley Fields. He'd already gotten burned once. He called one of those $39 Google ads for his 2016 Lexus LX, the locksmith showed up, charged $480, and the smart key only partially worked. It would unlock the car but push-to-start wouldn't respond. He found me through Google Guaranteed and the first thing he asked was how to spot a scam before it happens. Fair question.

I gave him my BSIS license number right on the phone, LCO#6792. He looked it up on the state website while we were still talking. I'm also NASTF certified, which means I have access to factory security data that unlicensed operators can't touch. I told him I'd fix what the other locksmith messed up.

I used my Smart Pro to reprogram his fob correctly with the full Lexus security handshake. His smart key, FCC ID HYQ14AAB, came back with all 4 buttons plus clean push-to-start. It came out to 343, exactly what I quoted. Dealer wanted 623 for the same job.

“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 LX Emergency Key Replacement FAQ

What to expect when we arrive

I lost all my Lexus keys. Can you still make a new one?▼

Yes. All-keys-lost is one of the most common calls we get on Lexus vehicles. We access and reset your Lexus smart key computer, then program brand new keys so the lost ones no longer start the car. This works on RX, ES, NX, IS, GX, UX, LS, LC, and RC models. Lexus dealers will tell you to tow the car in and can quote $500 to over $1,500 depending on the model. We come to you and handle the entire job on site.
