Question 1

Are you licensed and insured to work on Lexus vehicles like the 2019 LS?

Accepted Answer

Yes. EZ Car Keyz holds a California BSIS locksmith company license (LCO#6792) and is fully insured. We work on Lexus vehicles regularly, including later-generation models like the 2019 LS that require advanced programming equipment and proper credentials. You can verify the license directly through the California Bureau of Security and Investigative Services. We show up in a marked vehicle, carry verifiable identification, and the price we give you on the phone is the price you pay.

Question 2

How do I know EZ Car Keyz is not one of those scam locksmith operations?

Accepted Answer

That is a fair thing to ask, and the scam pattern is real. A fake listing, a low quote on the phone, and then a number that doubles when the tech shows up. They usually arrive in an unmarked car and cannot name the company they work for.

EZ Car Keyz has over 100,000 followers across YouTube and TikTok. You can watch us perform this exact type of work before you ever call. We give you a firm price upfront, show up in a marked vehicle, and that number does not move. The license number is public record. Look it up.

Question 3

Will the replacement smart key work exactly like my original 2019 Lexus LS fob?

Accepted Answer

Yes. Once the new fob is registered to your vehicle, it functions the same as the original. We test every function on site before we close the job.

One thing worth knowing: Lexus LS owners have reported cases where a vehicle security or keyless entry setting was toggled off in the vehicle's settings menu, making it look like a fob failure when nothing was actually wrong with the key hardware or its registration. We diagnose the actual problem first. We are not going to sell you a new fob if the issue is a settings conflict or a cracked shell that needs a board transfer.

Question 4

I have a working key but the 2019 LS shows a key-not-detected warning intermittently. Do I need a new fob?

Accepted Answer

Not necessarily. Intermittent key-not-detected warnings on this generation are one of the more common complaints you will find from LS owners, and the cause is not always the fob itself.

A few things to check first: the CR2032 voltage can read acceptable on a basic tester but still drop under the load the vehicle demands during communication. Swap the battery with a name-brand cell and see if the behavior changes. Beyond the battery, the internal board inside the fob can shift if the case has taken any impact, even a minor drop. That shifts the antenna position just enough to cause intermittent reads. The vehicle side also matters. The antennas inside the cabin that receive the fob signal have known sensitivity to interference from certain aftermarket accessories. If someone installed a dashcam, phone mount, or other electronics near the steering column area, that can create exactly this symptom.

If the warning only appears at the start button and not at the door handles, that helps narrow down whether it is a fob issue or a cabin antenna issue. Bring both those observations when you call.

Question 5

I lost both smart keys for my 2019 Lexus LS. Can new keys be made without going to the dealer?

Accepted Answer

Yes. All-keys-lost on the 2019 LS is a job we handle. It requires professional diagnostic equipment and the correct procedure for this generation's immobilizer, which involves a security data access step and a timed registration sequence. The old registered fobs get cleared out so they cannot be used to start the car. Plan for roughly 45 to 60 minutes on site. The dealer will tell you the same thing takes multiple days and requires the car to be towed in. We come to you in Del Mar Village.
