2019 Nissan Versa Note Key Replacement

2019 Versa Note key specs

Most Versa Notes use a conventional ignition with a chipped remote head key, or a plain chipped key on base cars without keyless entry. Higher trims could have an Intelligent Key with push-button start. Supplier catalogs list a four-button remote head key for 2014-2018 cars, a separate three-button CWTWB1U751 remote for 2014-2019 and a three-button fob under FCC ID KOBGT04A. Read the part number on your key before ordering a spare, since several versions exist.

What's specific to the 2019 Versa Note

2019 was the final model year of the Versa Note E12 (first generation). Late-run cars occasionally pick up running changes, so we check the VIN instead of assuming a 2019 Nissan Versa Note matches a 2014. A 2019 Nissan Versa Note is about 7 years old now. Original fob batteries are near the end of their life at this age, so weak range or a "key not detected" message is often a battery before it is a failed fob. Cars this age are often on their second owner, which is when a single remaining key and a request for a spare tend to show up.

Smart-key cars like the 2019 Versa Note can be targeted with relay attacks that extend the fob's signal from inside your home, so keep fobs away from exterior walls or in a signal-blocking pouch, and have any missing fob erased from the car.

Key options for the 2019 Nissan Versa Note

• Transponder (chip) key. Transponder chips come in families, such as Texas Instruments 4C and 4D, Philips 46, Megamos 48 and the newer 128-bit AES types, and a Nissan Versa Note only accepts the one its immobilizer was built around. That's why a hardware-store blank that looks right often won't start the car. We match the blank to the vehicle's chip and keyway before cutting. One more practical note: the chip lives in the plastic head, and when that head cracks, the chip can fall out or shift away from the antenna. If the car starts some days and not others, a damaged head is a frequent reason, and replacing the key before it quits entirely costs less than an all-keys-lost visit.
• Remote head key. A remote-head key puts two separate systems in one piece: a cut blade with a transponder chip that the immobilizer reads, and a small circuit board with buttons that signals the body control module to work the door locks. On a 2019 Nissan Versa Note with this style of key, each side is programmed separately. That explains some confusing failures. If the remote stops working but the car still starts, the problem is usually the battery or the remote board. If the buttons work but the engine won't run, look at the chip side. Knowing which half failed tells us whether you need a repair, a reprogram or a whole new key.
• Smart proximity key (push-to-start). Making a new smart key is mostly a programming job. The fob has to match the vehicle's FCC ID, frequency and chip, and then the keyless system must be told to accept it, normally through the OBD-II port. Depending on the platform, that can mean entering a PIN, waiting through a timed security procedure, or on some newer vehicles, using manufacturer online access. When every key is lost, certain models need a module removed and read on the bench. For your Nissan Versa Note E12 (first generation), we'll tell you which of those applies, and if a step is dealer-only, you'll hear it before we drive out. The emergency blade hidden inside the fob is cut by code during the same visit.

How the Nissan immobilizer works on the Versa Note

Nissan's immobilizer is called NATS, short for Nissan Anti-Theft System, and nearly every Nissan sold in the US since 2000 has one; a few early pickups and SUVs were built with plain keys. A chip in the key or fob has to answer the car before the engine is allowed to run, and a small security light on the dash blinks while the system is armed. Around 2000, cars such as the Maxima and Altima used the Texas Crypto 4D60 transponder. From about 2003, the 350Z, Armada, Frontier and later Altimas and Maximas moved to the Philips ID46, which stayed inside Nissan's Intelligent Key fobs for about a decade. Intelligent Key proximity fobs arrived first with a twist-knob ignition on Pathfinders, Armadas and the 2007 Maxima, and the 2007 Altima made push-button start standard. Some 2013-era fobs switched to Hitag 3 (ID47), and Hitag AES (4A) took over from the 2016 Maxima, the 2018 Leaf and Kicks, and the 2019 Altima. The newest platforms, including the Ariya, the 2025 Kicks and the 2025 Armada, use current-generation fobs and add security layers that make lost-key work slower. Your model year and the part number inside your fob tell us which system you have.

• Supplier catalogs list a four-button Versa Note remote head key with a transponder chip for 2014-2018 cars.
• The Versa Note was replaced by the third-generation Versa sedan rather than by a new hatchback.

Programming a 2019 Versa Note key

Chipped keys are cut by code or by decoding a lock, then registered through the OBD-II port with a PIN calculated from the security code. Intelligent Keys on equipped cars are registered the same way, and their emergency key is cut to the door. Keys not present are erased, so bring them all. Spares are routine, and all-keys-lost depends on which setup the car has.

Plain chipped keys are routine. Intelligent Key cars and all-keys-lost jobs may need extra steps or a dealer, which we confirm by VIN.

Lost every key to your Versa Note?

1. Gather your documents and the VIN. Find your registration or title and a government photo ID in the same name. Note the VIN, which is printed on the driver's side of the dashboard and usually on your insurance card. If the paperwork is locked in the car, tell us; we'll open the vehicle first and check it there.
2. Get into the vehicle without damage. If the car is locked, we open it with non-destructive tools such as an inflatable wedge and a long-reach rod, or by picking the door lock. Some vehicles need a careful approach to avoid triggering the alarm, which can interfere with programming later.
3. Originate a new key from the car. With no key to copy, the cuts come from the vehicle itself. We retrieve the key code through manufacturer channels where possible, or decode a door lock with a pick-decoder tool. Then we cut the blade on our code machine and confirm it turns the lock smoothly.
4. Program the key to the immobilizer. Next, the new key is introduced to the car's security system. Many vehicles allow this through the OBD-II port with a PIN or security procedure. Some all-keys-lost cases require reading a module on the bench, and a few platforms only allow dealer programming, which we'll tell you up front.
5. Erase missing keys and add a spare. Once the car starts, we remove the lost keys from memory wherever the system allows, so they can't start the engine if someone finds them. Making a second key during the same visit costs much less than a repeat all-keys-lost call down the road.

Why a spare key pays for itself

• When you sell or trade in the vehicle, buyers and dealers expect two keys. A missing key can come up during an appraisal or a private-sale negotiation, so having both on hand keeps the conversation about the car, not about what it will cost the next owner to replace one.
• Two drivers sharing one key is a daily negotiation. A second key lets a partner, teenager or coworker use the vehicle without handing keys back and forth in parking lots, and it means one person losing their key ring doesn't leave the whole household stuck.
• A spare turns a future all-keys-lost emergency into a simple add-a-key job. With one working key in hand, programming is quicker, and the chip or fob can often be paired without decoding locks or reading modules, which keeps the cost of a lost key far lower.

Dealer or mobile locksmith?

Dealers have one clear advantage: direct access to the manufacturer's own systems. Some newer vehicles tie key programming to online authorization that only a dealer can use, and certain all-keys-lost situations on specific platforms still require it. A good locksmith knows where those lines are. Where we can do the job, we use professional programming equipment that talks to the same immobilizer and keyless systems through the OBD-II port, and in many cases the result is identical: a properly registered key that starts the car. Where we can't, we can often still help by opening the vehicle, cutting a mechanical blade from code, or helping you gather what the dealer will ask for so that visit goes smoothly. For your Nissan Versa Note, ask us directly and you'll get a plain answer.

Versa Note key battery

Most fobs for a 2019 Nissan Versa Note open along a small slot in the seam; a coin or a plastic pry tool works better than a screwdriver, which chews up the housing. If the fob hides a mechanical blade, slide it out first, since the case often opens from that gap. Note which side of the old cell faces up, swap in a fresh replacement, and press the halves together until they click all the way around. Handle the new battery by its edges, because skin oil on the faces can hurt contact. In most cases the fob keeps its programming through a battery change, so test lock, unlock and start, and you're done.

How the job works

1. Identify the exact key your Versa Note uses. We ask a few quick questions on the phone: the year, whether the car starts with a turn key or a button, how many keys you have left, and whether the remote still works the doors. Then we check the VIN against our programming references so the van arrives with the correct blank or fob, not a close guess.
2. Verify ownership before any work. Before cutting or programming, we compare your government photo ID with the vehicle registration or title and check that the VIN on the paperwork matches the VIN on the dash. If the registration is locked inside, we open the car first, confirm the documents, and only then make the key.
3. Get the key code or decode the lock. If you still have a working key, we can read its cuts directly and check them against the factory depths for the Nissan keyway. A worn key gets corrected back to spec during this step, so the new key turns crisply instead of reproducing years of wear in a fresh piece of metal.
4. Cut the blade on-site. Our van carries a code-cutting machine that handles both traditional edge-cut blades and the laser-cut, side-milled profiles common on newer keys. The blade is cut to the code, then test-fitted in a door lock and the ignition or emergency keyhole to confirm smooth operation before any programming begins.
5. Program the chip, remote or smart key. With the blade done, we connect to the OBD-II port and register the new key with the immobilizer. Depending on the Nissan system, this may involve a security PIN, a timed waiting period, or on-board button sequences for the remote. On some vehicles we clone a working key's chip instead, when that's the more reliable path.
6. Test everything and clear out old keys. Before we leave, every function gets checked: doors, trunk or liftgate, panic button, remote range, engine start, and the emergency blade in the driver's door. If keys are missing, we delete them from the car's memory where the system allows, so a lost key can no longer start the engine.

What affects the price of a Versa Note key

• The type of key. Price follows complexity. The more the key does, the more it costs to replace: brass blade, then chip, then remote buttons, then full keyless entry and push-button start. If your Versa Note came with different key styles by trim, the one your car actually uses is the one that sets the quote.
• Factory or aftermarket parts. Factory keys and fobs carry the manufacturer's part number and usually the highest parts cost. Quality aftermarket keys use compatible electronics at a lower price and work well on many vehicles. We tell you which options we trust for your car, and where an aftermarket version has known range or fit issues, we steer you to OEM.
• Programming complexity and security access. Some immobilizers accept a new key with a few on-board steps. Others need a PIN code, a timed security wait, manufacturer online access, or removing a module to read its data. Every extra layer of security on the Nissan system adds equipment time and labor to the job.
• Travel, timing and extra repairs. Sometimes a key problem is really a lock problem: an ignition that won't turn even with the right key, or a door cylinder that has been jammed for years. Fixing those is separate work. We point them out, explain the options, and quote the whole job up front so the bill holds no surprises.

Common Nissan key problems

• Secondhand Intelligent Keys are a common dead end. Many newer Hitag AES fobs lock to the first car that learns them, and a fob with a different FCC ID or part number won't register even when it looks identical to yours.
• Nissan does not keep key numbers on file. The small metal key number plate that came with your keys is the only record, so photograph it and store it outside the car; without it, an all-keys-lost job starts with decoding a lock.
• Nissan manuals warn against leaving the Intelligent Key anywhere above 140 degrees Fahrenheit. A fob left on the dash of a parked car during an Inland Empire summer can get that hot, which shortens battery life and can damage the circuit board.

Tips from a mobile locksmith

• Learn your car's dead-fob start method now, in the driveway, rather than in a dark parking lot later. Depending on the make, you hold the fob against the start button or place it in a marked pocket in the console. Also find the hidden keyhole on the driver's door handle and practice using the emergency blade.
• Be careful with discount fobs from online marketplaces. A listing may match your remote's shape while using a different frequency, chip or FCC ID, and many used smart keys are locked to their original vehicle. If you already bought one, send us the listing or a photo before the visit so nobody pays for a programming attempt that can't work.
• On any vehicle with a turn-key ignition, keep the key ring light. A heavy cluster of keys, tools and charms swings with every bump and slowly wears the ignition wafers and the key itself. When the key starts to stick or needs a wiggle to turn, deal with it early, before it stops turning entirely.

Proof of ownership

Before we cut or program a key for any vehicle, we verify that you have the right to it. Please have two things ready: the current registration or the title, and a government-issued photo ID with a matching name. We also check that the VIN on those documents matches the VIN plate on the dashboard. If the registration is locked inside the car, that's fine; we open the vehicle first, check the paperwork in the glove box, and only then make the key. If something doesn't line up, we stop and sort it out before any key is made.
