Question 1

Are you licensed and insured to work on Nissan vehicles?

Accepted Answer

Yes. EZ Car Keyz holds a California Bureau of Security and Investigative Services locksmith license and carries full liability insurance. For the 2022 Maxima specifically, programming a replacement smart key requires professional diagnostic equipment that communicates with the vehicle's immobilizer and security system. We have the tools and the credentials to do that legally and correctly. Not every locksmith advertising online can say the same. A lot of guys have a generic OBD programmer and hope for the best. If a locksmith can't tell you over the phone what equipment they use on a late-model Nissan, that's your answer about whether to hire them.

Question 2

How do I know you are not a scam locksmith?

Accepted Answer

The pattern is always the same. Low number quoted on the phone, price doubles once you're stuck and they've got your attention. Then they can't answer basic questions about your specific vehicle.

Here's what a real locksmith does: they tell you over the phone what the job involves on a 2022 Maxima, what equipment is needed, and give you a real estimate before anyone drives anywhere. We do all of that. We also carry documentation of our license on every call and we show our work, literally, we've documented hundreds of jobs on video so you can see exactly how we operate before you decide to call.

Ask any locksmith you're considering: what tool do you use to program a 2022 Maxima smart key, and what happens if the programming fails? If they fumble that, walk away.

Question 3

Will the replacement key work exactly like my original?

Accepted Answer

Yes. A properly programmed replacement fob for the 2022 Maxima gets registered to your vehicle's immobilizer the same way the factory unit was. The engine starts, the security system recognizes it, and the remote functions operate normally. We test every single button and verify the dash warning is clear before we close the job. We don't hand you a key and drive off hoping it holds. If something isn't right, we sort it on site.

Question 4

I bought a replacement fob online. Can you just program it, or do I need to buy one from you?

Accepted Answer

You can bring your own fob and we can attempt to program it, but there are real risks with aftermarket and gray-market fobs for this vehicle. The 2022 Maxima smart key system uses a specific transponder chip that has to match what the immobilizer expects. Some fobs sold online look identical on the outside but have counterfeit or incompatible internals. If the chip doesn't match the required spec, the immobilizer will reject it no matter how good the programming equipment is.

If you want to go that route, we can test the fob before we start and let you know whether it looks viable. But if it fails, you've still paid for a service call and you're back to needing a correct fob anyway. Buying through us means we know the part is right before we begin.

Question 5

My 2022 Maxima starts fine, but one of the door handles stopped responding to the touch sensor. Is that a fob problem?

Accepted Answer

Almost certainly not the fob. If the car starts and other handles respond normally, the fob is communicating with the system just fine. Touch sensors on door handles are a known wear point. Dirt, moisture, and sun exposure around the sensor area can degrade responsiveness over time, and California sun near the Santee Lakes Area does real work on exterior surfaces. Start by cleaning the handle area thoroughly and retesting. If it stays dead on one door only, the fault is isolated to that handle sensor or the wiring behind it, not your key. That's a separate job from anything we handle, but it's good to rule out the key first so you're not chasing the wrong problem.
