Question 1

My key broke in the ignition. Can you get it out?

Accepted Answer

Yes, broken key extraction is a standard mobile job. Specialized extraction tools let me remove the broken piece without pulling the whole cylinder out of the dash.

One thing worth knowing on the 2020 Murano specifically: this vehicle uses a push-button start, so a key blade is not going in the ignition in the first place. If a blade broke off anywhere on your Murano, it's most likely in the driver's door lock cylinder, which is where the emergency blade inside the fob gets used. That's a different extraction job than an ignition pull, and it's generally simpler. Once the piece is out, I can cut a replacement blade and verify the full fob is still functioning on site.

Question 2

What exactly is a smart key and how does the 2020 Murano use it?

Accepted Answer

The 2020 Murano uses a proximity-style Intelligent Key fob. You carry it in your pocket, and the car detects it passively when you grab the door handle. Touch the handle to unlock, press the button on the handle to lock, and start the engine with the push-button on the dash as long as the fob is inside the cabin.

The fob also has a physical emergency blade folded inside. That blade opens the door if the battery dies completely and the passive detection stops working. It does not bypass the vehicle's electronic security for starting purposes, so if the fob itself fails, you still need a properly paired replacement to drive.

The fob takes a CR2032 battery. Five buttons total. When it's time for a replacement, the new fob has to be paired to your specific vehicle using diagnostic equipment. It's not something you can do with a button sequence at home.

Question 3

My Murano says key not detected. What do I do first?

Accepted Answer

Start with the battery. The CR2032 in the Murano fob is the first thing to rule out, and Murano owners on Nissan forums report them going flat in under two years with regular use.

If the warning is showing but the car still starts sometimes, that intermittent behavior is usually a contact issue inside the fob, not a dead battery. The tab that presses against the CR2032 can flatten out over time and lose connection when the case flexes. Popping the fob open and reseating the battery takes about a minute.

If you've got a fresh battery seated correctly and the warning is still there, try this: hold the fob directly against the start button on the dash and press the brake at the same time. The button has a built-in inductive reader that picks up a backup signal from the fob even when the battery is too low for normal wireless range. That gets you moving.

If none of that works, the issue could be the fob itself, the vehicle's antenna system, or a low 12-volt car battery interfering with the security system's normal operation. That's when you call me.

Question 4

Can I buy a fob online and just have it programmed, or does it have to come from a dealer?

Accepted Answer

You can buy an aftermarket fob online and have it programmed by a locksmith with the right equipment. It does not have to come from the dealer. The fob for your 2020 Murano is widely available from third-party suppliers, and the part that actually matters is the programming, not the source of the hardware.

A couple of things to watch: make sure the replacement fob matches your original's button count and frequency. If the fob you buy is wrong for your specific vehicle configuration, no amount of programming will make it work. Buy from a reputable supplier, keep the listing, and confirm before you commit. When I do this job, I either source the part myself or verify what you've brought before I start the pairing process.

Dealer route is always an option, but you're paying for their overhead and waiting on their schedule. Most Murano owners who've priced it out come back saying the difference is significant.

Question 5

All my keys are gone. Can you still make a new one, or is the car just stuck?

Accepted Answer

All-keys-lost on a 2020 Murano is a solvable job. Not a quick one, but solvable.

When no registered fob is present, the vehicle's security system goes into a locked state and the normal add-a-key process won't work. Getting out of that requires a full security reset through the OBD port using professional-grade diagnostic equipment, after which a new fob can be enrolled and the vehicle can start normally again.

The process takes longer than a standard spare key job, and it does require the right tools. This is not a DIY procedure and there's no ignition-turn shortcut for a push-button start vehicle. But it's a routine call for a locksmith set up for Nissan work. I can do it on site, at your location in Ventura or out by Faria Beach, without towing the car anywhere.
