2023 Lexus RZ
Licensed and Bonded Key Replacement 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 2023 Lexus RZ key fob use?

The 2023 Lexus RZ uses a CR2032 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.

2023 Lexus RZ Smart key Replacement - Fast, Affordable & Professional

A customer at the country club in Thousand Oaks told me he'd already paid another locksmith full price for a 2023 Lexus RZ key that never worked. The engine cranked but the smart system killed fuel after two seconds. The other locksmith said the smart ECU was bad and walked away.

The ECU was fine. The locksmith hadn't completed the full Lexus key registration. The smart system requires a specific security sequence including seed calculation and a timed registration. Rushing it means the key writes temporarily but doesn't commit to permanent memory.

I used my TOY43 Lishi to verify the blade cut, then connected through OBD. I cleared the failed registration, ran a clean smart key learn with the full security timer, and confirmed the new key was permanently written. His key with remote, FCC ID HYQ14FLC, started the engine clean on three consecutive tests. I showed him the IM608 confirmation screen.

He paid me 329. Dealer charges 602 for the same work. He'd already paid the first locksmith too. But I could make sure the job was actually done right this time.

“My car keys were stolen on a cold evening and Nick drove all the way out to Santa Barbara. He got into my car, made a new key, and charged $100 less than another company. Friendly, skilled, trustworthy, and genuinely caring. Nick is a hero.”

What to Do When You Lose Every Lexus Key

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.
