Question 1

Are you licensed and insured to work on Lexus vehicles?

Accepted Answer

Yes. EZ Car Keyz holds a California BSIS locksmith company license (LCO#6792) and is fully insured. You can verify the license directly through the California Bureau of Security and Investigative Services. We work on Lexus regularly, including the Smart Key system on the RX, and we carry the diagnostic equipment required to register new fobs and handle immobilizer enrollment on site. Eight-plus years in business, real reviews, marked vehicle, and a price that doesn't change when we arrive.

Question 2

How do I know you are not a scam locksmith?

Accepted Answer

Scam locksmiths are a legitimate problem, especially for Lexus owners because the job sounds expensive and the fake operators know it. The pattern is consistent: a suspiciously low quote on the phone, an unmarked car, a tech who can't name the company, and a final bill that doubled or tripled once they showed up.

EZ Car Keyz has over 100,000 followers on YouTube and TikTok where you can watch us do this exact work on real vehicles. We give a firm price on the phone. We show up in a marked van. The price you hear is the price you pay. Our license number is posted publicly and checkable. That's the short version of why we're not that.

Question 3

Will the replacement key work exactly like my original?

Accepted Answer

Yes. Lock, unlock, the trunk release button, all of it. We test every function on the fob before we leave your vehicle.

One thing worth knowing: Lexus owners on forums have run into situations where the vehicle security system had a configuration issue that made a perfectly good fob appear dead. Dealers occasionally quoted full fob replacements when the actual fix was a settings correction. We diagnose the system before we recommend replacing anything. If your existing fob can be saved, we'll tell you that first.

Question 4

I bought a replacement fob online for my 2013 RX. Can I program it myself or do I need a technician?

Accepted Answer

You'll need a technician. The 2013 RX Smart Key system does not have an onboard self-programming sequence the way older bladed transponder setups did. There's no ignition-turn trick, no button combination, no DIY relearn. Registering a new fob requires diagnostic equipment connected to the OBD port to communicate with the vehicle's immobilizer and security system.

The fob you bought online is likely a valid uncut shell, but it won't do anything until it's enrolled. Bring it to us and we can program it, plus cut the emergency insert blade inside to your vehicle. That's a common combo job and it costs less than a dealership would charge for the fob alone.

Question 5

The touch sensor on my door handle stopped unlocking the car. Is that a fob problem or something else?

Accepted Answer

If the start button still recognizes the key and other fob functions work, the fob is almost certainly fine.

Door handle touch unlock on the RX is a known friction point for owners. The sensor lives in the handle itself, and issues tend to be localized: one door stops responding while the others still work. Dirt and moisture around the handle can interfere with the sensor, so cleaning the area and retesting is always the first step. If it stays isolated to one door after that, you're looking at the handle sensor or the wiring on that door, not the key or the vehicle security system. That's a separate diagnosis from a key replacement job.
