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 (LCO#6792) and carries full business insurance. For a 2004 Murano, the job involves cutting a key blade, registering a transponder to the vehicle's immobilizer, and pairing the remote. That's legitimate automotive locksmith work, and we have the tools and credentials to do it correctly. If you're calling around, ask any locksmith whether they can program the transponder on-site for this specific vehicle and generation. The answer tells you fast whether they've actually done the job before.

Question 2

How do I know you're not a scam locksmith?

Accepted Answer

Scam locksmiths follow a pattern: a suspiciously low quote on the phone, then a ballooning number once you're stuck and out of options. They also tend to go vague when you ask specific questions about your vehicle.

A legitimate locksmith working on a 2004 Murano should be able to tell you on the phone what the job involves, what equipment they use, and give you a real quote before they arrive. We can.

We also document our work publicly. Our YouTube and TikTok channels show the actual process on real vehicles. Over 100,000 people follow that work. That kind of record isn't something a scam operation builds.

Ask questions before anyone shows up. Any locksmith who can't answer them clearly isn't the one you want touching your car.

Question 3

Will the replacement key work exactly like the original?

Accepted Answer

Yes. A properly programmed replacement remote head key for the 2004 Murano does everything the original did. The transponder communicates with the immobilizer so the engine starts and runs normally. The remote functions handle lock, unlock, and trunk. We test every single function on-site before the job is closed out.

The reason we test in front of you is simple. You should watch the car confirm every function, not take our word for it. If anything doesn't behave exactly right, we sort it out then and there, not after we've left.

Question 4

I bought a replacement fob online. Can you just program it, or do I need a different key?

Accepted Answer

This one comes up often with 2004 Murano owners. The remote head key for this vehicle is a combined unit, meaning the remote and the transponder chip are integrated into the same key body. If you bought a shell or a remote-only fob online, it may not have the correct transponder component inside, and if the transponder isn't the right type for this vehicle, programming won't complete correctly.

Before you show up or I come to you, check what you actually have. If the factory FCC ID on the fob matches what was originally on your key, there's a reasonable chance it's the right unit. If it's a generic aftermarket shell with no chip information listed, odds are lower. Call me and describe what you bought. I can usually tell you over the phone whether it's worth attempting or whether you need a correct replacement unit. Bringing the wrong part to a programming appointment wastes your time and mine.

Question 5

My 2004 Murano starts fine but the remote stopped working. Do I need the whole key reprogrammed?

Accepted Answer

Not necessarily. If the engine starts normally, the transponder side is still registered and talking to the immobilizer. The remote side is a separate function. First thing to check is the battery. These take a CR1620, and a dead or weak cell will kill remote range entirely while leaving the start function untouched. Swap the battery and retest.

If a fresh battery doesn't bring it back, the remote may have lost its pairing to the vehicle, which can happen after a battery disconnect or certain electrical events. That's a reprogramming job but it doesn't involve the transponder side. If the remote housing itself is cracked or the buttons are physically damaged, you're looking at a replacement key. Call me and describe what it's doing. A two-minute conversation usually narrows it down before I'm in the driveway.
