Question 1

I'm locked out with no spare fob. Can you come to me in San Ysidro?

Accepted Answer

Yes, that's exactly what we do. Call us and we come to you on Beyer Blvd Corridor or anywhere else in San Ysidro - parking lot, apartment complex, street parking, wherever the NX is sitting.

One thing to know about the 2023 NX specifically: there's no traditional ignition cylinder, so the emergency entry point when you're locked out is a mechanical door lock cylinder hidden under the driver's door handle cover. We know where it is and how to work it. You don't need to figure that out on your own.

We carry the equipment to handle everything on site. No tow, no dealer appointment, no waiting on a callback to schedule. One call gets the process started.

Question 2

The Lexus dealer told me I have to tow my NX in for a key replacement. Is that true?

Accepted Answer

It's true that dealers require the vehicle on their lot. It is not true that a tow is your only option.

A mobile locksmith with the right equipment can handle 2023 NX key replacement at the vehicle's location. Programming goes through the OBD port, so the car doesn't need to move. Dealers tell you to tow it in because that's their process - their tools are at their shop. Our tools come to you.

Towing adds cost and wait time before the dealer even looks at the job. Skipping that step alone saves you a meaningful chunk of the total bill, before you even compare the key replacement cost itself.

Question 3

What do I need to show to prove I own the 2023 NX before you'll make a key?

Accepted Answer

Valid photo ID and proof of ownership - your registration or title works. We verify the VIN from the dash plate or the door jamb sticker to confirm everything matches before we touch anything.

That's the same baseline a dealer uses. The difference is we do it on site in a few minutes rather than running you through a service desk process. We're also confirming key specs directly from the VIN at the same time, so it's not a separate step - it's all part of the intake before the job starts.

Question 4

My 2023 NX shows a key-not-detected warning but the fob is right there. What's going on?

Accepted Answer

Few things can cause that. Start with the CR2032 in the fob - a low battery is the most common trigger for that warning even when the fob is physically present. If the cell is weak, the fob's signal doesn't always register reliably with the antennas in the vehicle.

If a fresh CR2032 doesn't fix it, the next step is to hold the fob directly against the start button when you press it. That's a built-in backup on the NX - the button can read the fob's signal by direct contact when the wireless range is compromised. If the car starts that way, the fob is still alive but the battery is the weak point.

If neither of those works, or if the warning is appearing even while driving after a normal start, that points toward a communication issue between the fob and the vehicle's security system that needs to be diagnosed with equipment. That's when you call us rather than guessing at it.

Question 5

I bought a replacement fob online for my 2023 NX. Can I program it myself?

Accepted Answer

No. The 2023 NX has no owner-accessible self-programming sequence for smart fobs. There is no button combination, no ignition cycle trick, nothing like that. Fob registration on this vehicle requires professional diagnostic equipment connected to the OBD port.

If you already bought one online, it's not a wasted purchase - the fob itself can still be used once it's properly programmed by someone with the right tools. Just know that the part and the programming are two separate steps, and the second step is not DIY on this system.
