Nissan Key Replacement, Key Fob Programming & Smart Key Service
From DA34 transponder keys to Intelligent Key proximity fobs, we cut and program Nissan keys at your location across Palm Beach County.
Nissan keys moved from the DA34 and NI04T transponder keyways to the Intelligent Key proximity system used across most of today's lineup. The fob family changed roughly every generation (KBRASTU15, CWTWB1U751, KR55WK48903, then KR5TXN7), so the year and ignition type decide which key your Nissan needs.
Our mobile techs cut and program keys for the Nissan lineup most common in Palm Beach County, including the Altima, Rogue, and Pathfinder. We carry the blanks and programming tools in the van, confirm whether your Nissan is turn-key or push-to-start, and finish most jobs curbside in one visit.
Nissan models we service

Nissan key types by generation
Nissan keys changed significantly from one era to the next. The right blank, chip, and programming path depend on the year, trim, and ignition type, which is why we ask for the details before selecting a key.
2000 to 2006: DA34 transponder keys
Early Nissans used the DA34 keyway with transponder chips and remote fobs such as the KBRASTU15. The blade fits the door and ignition, but the engine starts only when the chip is matched to the immobilizer.
2007 to 2018: NI04T keyway and Intelligent Key launch
Nissan rolled out the NI04T keyway and introduced the Intelligent Key proximity system, moving through the CWTWB1U751 and KR55WK48903 fob families. Many of these models split between turn-key and push-to-start by trim.
2019 to present: latest Intelligent Key fobs
Modern push-to-start Nissans use the latest Intelligent Key proximity fobs (FCC KR5TXN7) with an emergency blade inside. Lost smart keys are programmed to the specific vehicle.
Nissan key data by model
Verified blank, chip, and FCC references are marked accordingly. Where a value depends on trim, button count, or production date, confirm it from the original key, a VIN lookup, or a supplier catalog before cutting or ordering.
Data is drawn from professional locksmith key references. It is a starting point for identification, not a guarantee for your specific vehicle.
Nissan Altima Key Replacement
The Altima is one of the most common cars we make keys for. It spans DA34 transponder keys, Intelligent Keys on many trims, and the latest proximity fobs depending on the year.

Nissan Key & Fob FAQs
Can you replace a Nissan key if I lost all of them?
Yes. We program a new key or Intelligent Key to your vehicle on site. All-keys-lost jobs on push-to-start models take a little longer because the key is programmed directly to the car.
Do you program Nissan Intelligent Keys (push-to-start)?
Yes. We supply and program proximity Intelligent Keys such as the KR55WK48903 and KR5TXN7 and cut the emergency blade inside.
My Nissan key turns but won't start. What's wrong?
The transponder in the key has to match the immobilizer. If the blade is fine but the engine won't start, the chip may have failed and the key needs reprogramming or replacement.
Is my Altima turn-key or push-to-start?
Both exist across the years. If you insert and twist a key it is turn-key; if you press a button it is an Intelligent Key. Tell us which so we bring the correct key.
How much is a replacement Nissan key?
It depends on whether it is a transponder key or an Intelligent Key, plus the year. We quote an up-front price before we head out.
Can you cut a spare Nissan key from my working one?
Yes. A spare made from a working key is the cheapest insurance against a future lockout, and we cut and program it on the spot.
Do you come to my home or workplace?
Yes. We are fully mobile and service Nissans wherever they are parked across Palm Beach County.
Why is my Nissan Intelligent Key not detected?
It is often a dead coin battery rather than a failed fob. We can test it, replace the battery, or program a new Intelligent Key if needed.
What do you need to make a Nissan key?
The year, model, VIN, whether it is turn-key or push-to-start, and proof of ownership. A photo of your current key helps us match it.
Do you service Nissan SUVs as well as cars?
Yes. We handle the Rogue, Pathfinder, and the rest of the Nissan lineup, not just the sedans.
