2007 Lexus LX
Certified Locksmith 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 2007 Lexus LX key fob use?

The 2007 Lexus LX uses a CR1616 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.

2007 Lexus LX Remote head key Replacement - Fast, Affordable & Professional

Here's exactly what happens when I replace a 2007 Lexus LX key. I verify your identity and ownership. Then I decode the lock and cut the emergency blade. From there I connect my IM608 to OBD, access the Lexus smart ECU, read the security seed, calculate the encryption key, and register the new fob. After that, I test. Not just "does it start." I test every button, remote range from 30 feet, lock and unlock, trunk, and three consecutive push-to-starts.

A parent at the tennis club in Ventura watched me work on her LX and said the testing phase was what stood out. She expected me to hand over the key and leave. Instead I walked across the parking lot pressing buttons, testing range from different angles, and started the car three times.

Her remote head key, FCC ID HYQ1512V, was a 3-button smart key. I verified every button, checked the range, and did three clean starts. I told her that testing is the part most locksmiths skip.

That testing process is included in the 185 I charge. Dealers charge 395 and not all of them test as thoroughly.

Lost Your Lexus LX Key? Here's What to Know

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.
