The system
Three ways a Murano has been started
The Murano arrived in the United States for the 2003 model year as a stylish midsize crossover, and it quickly became known for its technology. Across its generations, Nissan has started the Murano in three different ways: with a conventional key in a slot, with a knob on the column that turns only when an Intelligent Key is nearby, and with a push button. Which one your Murano has determines almost everything about the key job.
The first generation, sold through the mid 2000s, came with either a conventional transponder key or Nissan's Intelligent Key depending on trim and options. On Intelligent Key vehicles, there is no key slot in the usual sense. Instead there is a round knob where the ignition would be. With the fob in your pocket, you turn the knob to start the engine. Without a recognized fob, the knob will not turn. Many people who buy one of these used have never seen that arrangement before.
The knob often has a small cover or release that allows the emergency blade from inside the fob to be inserted, which is a backup for certain situations. The owner's manual explains exactly how it works on each version, and it is worth reading before you are stuck.
The second generation, sold from the 2009 model year into the mid 2010s, moved the Murano to push button start with Intelligent Key. The CrossCabriolet, a two door convertible version sold for a few years in that period, follows the same general approach, though its specific parts should always be confirmed separately.
The third generation, which arrived for 2015, continued with Intelligent Key and push button start, using updated electronics. A newer generation followed in the mid 2020s with Nissan's latest systems. On the most recent vehicles, some registration steps are more involved, and certain all keys lost situations may require dealer access.
Tucked inside each Murano fob is a slim metal key. Slide it out and it turns the driver door lock on the night the fob or the car battery gives up.
Before we program anything, we ask the model year and how the engine starts: key, knob or button. That answer tells us which parts and procedure to bring.
Systems by generation
The twist knob years, the push button years, and how to tell them apart
Murano owners sometimes describe their ignition as a key that is not a key, a switch, or a dial. All of those descriptions usually point to the same thing: the first generation Intelligent Key knob. Later Muranos use a start button that most drivers recognize immediately. Getting that detail right on the phone is the difference between arriving with the correct fob and arriving with the wrong one.
Think of these rows as a way to start the conversation. Muranos changed hands often, some had modules swapped along the way, and the one in your driveway gets checked in person.
| Approximate years | Common key types | How it starts | What the job usually involves |
|---|---|---|---|
| 2003 to 2007 | Transponder key on some trims, Intelligent Key on others | Turn key, or twist knob with Intelligent Key | Identify the ignition type, then register a key or a fob to match |
| 2009 to 2014, including CrossCabriolet | Intelligent Key with emergency blade | Push button on most | Fob registration, emergency blade cutting, button checks |
| 2015 to early 2020s | Intelligent Key | Push button | Fob registration with Nissan's updated electronics |
| Mid 2020s generation | Intelligent Key | Push button | Newer procedures, some all keys lost cases needing the dealer |
For first generation Muranos with a conventional key, the job looks like most transponder key work: cut a blade that fits the doors and ignition, and register the chip so the immobilizer accepts it. Remote functions may be built into the key head or handled by a separate fob depending on the vehicle. We match what your Murano originally had.
For first generation Muranos with the twist knob, the fob is the key. It has to be registered to the vehicle so the knob will release and the engine will start, and the emergency blade inside it has to be cut to open the driver door. These vehicles are now old enough that the knob assembly itself can wear or fail, and a knob that will not turn even with a recognized fob points to the ignition hardware rather than the fob. We check that before selling you a new fob.
For second and third generation Muranos, the push button system is familiar to most drivers. The fob is registered for entry and starting, the door handle request buttons unlock the vehicle when the fob is nearby, and a backup start method lets you start the engine with a weak fob by holding it close to the button. Some Nissan systems require a security code derived from the vehicle before a new fob can be added, and that step is part of the procedure where supported.
Recent Muranos are easiest when one fob survives and a second is being added. A late model Murano with no fob at all may be a Nissan job, and the call is where you find that out.
A note on the CrossCabriolet
The Murano CrossCabriolet is uncommon, and its convertible top and two door body make it different enough that we always confirm its parts separately rather than assuming it matches the four door Murano of the same year. If you own one, say so on the call. Convertible owners also have a specific security concern: a soft top can be cut, so a key left inside the vehicle is more exposed than in a hardtop. Keep spares at home.
Older Muranos and the one fob problem
First and second generation Muranos are now commonly owned by second or third owners, and many of those vehicles changed hands with a single fob. That one fob is often a decade or more old. Its battery contacts may be corroded, its case may be cracked, and its buttons may be worn. If it fails or is lost, the vehicle becomes an all keys lost case. Adding a second fob while the first still works is usually a simpler job and the most useful thing an owner of an older Murano can do.
What a Murano fob appointment looks like
When we arrive, the first step is confirming ownership and the vehicle details against what you told us on the phone: year, trim, start method and how many fobs you want to end up with. If the doors are locked and no fob works, we open the driver door without damaging the weatherstripping or the door panel. Then we connect to the vehicle and check that the security system is communicating normally. A vehicle with a communication fault is not a candidate for new fobs until that fault is understood, and we tell you so rather than pressing on.
Next comes the fob itself. We confirm that the replacement matches your vehicle's specifications, then register it along with any existing fobs you want to keep. On systems that require a security code, obtaining it is part of this step. The emergency blade inside the fob is cut so it opens the driver door, and we try it in the lock rather than assuming it fits.
Finally, we test everything with each fob: walking up and touching the door handle, the lock and unlock buttons, the liftgate, panic, and starting the engine with the button or knob. We also try the backup start method so you know how it feels before you ever need it. The job is complete when every fob does everything it is supposed to do, not when the programming screen says it succeeded.
Getting a Murano ready for key work
Know the model year and how you start the engine: key, knob or button. If you have any fob or key, keep it with the vehicle. Gather every fob you want to keep working, because on many Nissan systems all fobs are registered together, and any fob not present may stop working afterward.
Jot down any message the dash shows when you try to start, word for word. Nissan's wording often tells us whether the car sees no fob, a weak fob or a fault elsewhere. Then call (302) 534-0150 and tell us which lot or driveway in New Castle or Kent county the Murano is sitting in.
Two routes
Locksmith or Nissan dealer for a Murano fob?
A Nissan dealer can supply and register a new fob. With no working fob, getting the Murano to the dealer usually means a tow. Crossovers with all wheel drive should generally be moved on a flatbed, which narrows the options and can add waiting time.
We bring the fob to the Murano. Twist knob era fobs and push button fobs for the common years, plus the cutting and registration equipment, mean no flatbed for a supported vehicle.
Nissan is the better stop for a Murano whose intelligent key unit or body control module has just been swapped, one under an open campaign, one whose network will not communicate, or a very new Murano that Nissan limits to its own terminal.
Original Nissan fobs and quality aftermarket fobs are both available for many years. Fobs that look alike can hide different electronics, so we match by vehicle specification, not by appearance, and tell you which type we are supplying.
For twist knob vehicles, the dealer route and the locksmith route both depend on the ignition knob working. If the knob assembly has failed, that part needs attention first, regardless of who supplies the fob.
Ask about removing lost fobs. A fob lost in a restaurant, a gym or a parking garage is worth deleting from the vehicle's memory so it can no longer start the engine.
If you have one working fob and simply want a spare, the choice is mostly convenience. A mobile visit fits into an evening at home rather than a weekday at a service desk.
If your Murano is outside what we can do on site, we say so before we drive out.
Diagnosis
Common Murano key problems
On twist knob Muranos, a knob that will not turn with the fob in the cabin usually points to a weak fob battery, a fob the vehicle no longer recognizes, or wear in the knob assembly. Replace the fob battery first. If a second fob behaves the same way, suspect the knob or the vehicle.
On push button Muranos, a message that the key is not detected most often means a weak fob battery. Holding the fob close to the start button, as described in the owner's manual, usually starts the engine anyway.
Door handle request buttons can fail over time. If the fob's lock and unlock buttons work but touching the handle button does nothing, the handle switch is the likely cause, not the fob.
A weak twelve volt battery can make every fob look dead. The security system needs stable voltage to detect the fob. Charge the battery before buying a new fob.
Fob cases on older Muranos crack and the button covers wear through. If the internals are healthy, a new case with the electronics transferred can extend the fob's life.
Phones, tablets, other fobs and metal objects near the fob can interfere with detection. Keep the fob away from other electronics when troubleshooting.
A fob that was washed or soaked often loses its buttons first. The part that talks to the immobilizer may still work using the backup start method, which can get you home.
A Murano that shows no reaction at all, with dark dash lights and no door response, almost always has a battery problem. Use the emergency blade to open the driver door, then deal with the battery before judging the fob.

Before service
What to have ready for a Murano
Murano owners often bought the vehicle for comfort and style, and they want the fob working exactly as before without a trip to the dealer.
If a fob survives, photograph the button side. Muranos differ in whether the fob carries a liftgate or remote start button.
The registration or title and the named owner's license are all we need. If a family member owns the Murano, their signed note or a call works.
For a leased Murano, the lease agreement shows your right to the vehicle.
Mention any previous repairs to the ignition knob, the start button, the door handles or the electrical system. Those can change what the job requires.
If the fob was lost with house keys, consider whether the home locks should be rekeyed. We can arrange that as well.
On twist knob Muranos, please leave the knob alone once we start. Turning it partway through can interrupt registration.
We test door handle entry, lock and unlock buttons, liftgate, panic, and engine start with every fob you want to keep.
On twist knob vehicles, we also confirm the knob turns smoothly with each fob before finishing.
If the knob assembly or start button itself is at fault, we show you the symptom and explain the repair rather than selling a fob that will not help.
Straight answers
Nissan Murano key replacement FAQ
Can a Murano fob be made if I lost every one?
For many Murano years, yes. All keys lost work on an Intelligent Key vehicle means registering a new fob, which on some Nissan systems requires a security code derived from the vehicle, and cutting the emergency blade for the driver door. Conventional key Muranos need a cut and registered transponder key. Some of the newest Muranos may require the dealer. Tell us the year and start method on the call.
What is the knob where my Murano's key should go?
On many first generation Muranos with Intelligent Key, the ignition is a knob rather than a key slot. With a recognized fob in the vehicle, you turn the knob to start the engine. Without one, the knob will not turn. The owner's manual explains the backup procedures for that system. A replacement for these vehicles is a fob, not a conventional key.
My Murano says key not detected. What should I try?
Replace the fob battery first. Then try the backup start method from the owner's manual, which on push button Muranos usually involves holding the fob close to the start button. Keep phones and other electronics away from the fob. If every fob shows the same message, look at the vehicle battery or electronics before buying a new fob.
Will a new fob affect my other Murano fobs?
On many Nissan systems, fobs are registered as a set, and any fob not present during registration may stop working. Bring every fob you want to keep. A fob found later can usually be registered again during another visit.
Can a cracked Murano fob be put in a new case?
Murano fob shells from the first two generations crack at the key ring loop and along the seam. When the car still starts with that fob, a replacement case is usually all it needs. Corrosion from a spilled drink or a rainstorm on the board is different, and at that point a new fob is the dependable choice.
Is the CrossCabriolet key the same as a regular Murano key?
The CrossCabriolet follows the same general Intelligent Key approach as the Murano of its era, but we confirm its specific parts separately rather than assuming they match. Tell us it is a CrossCabriolet when you call so we bring a compatible fob.
When should a Murano go to the Nissan dealer for a fob?
A worn twist knob, a start button that fails, or a swapped control module can each send a Murano to Nissan, as can a campaign notice or a very new build with restricted registration. For ordinary lost or broken fobs on a healthy Murano, the work happens at the curb.
