🔧 PRO TIP
The 2019+ Altima moved to a 4A AES chip, which is not cloneable. You cannot copy an existing key the way older Nissans allowed. Every new key must be a virgin blank programmed fresh to the car through the BCM.

2019 Nissan Altima Smart Key Replacement - Fast, Affordable & Professional

If you want the fastest possible 2019 Nissan Altima key replacement, here's what to have ready when I arrive. Your VIN, the 17-character code on the dashboard driver's side, visible through the windshield. Your ID proving ownership. And if you have a working key, even a dead one, keep it nearby because add-a-key is faster than all-keys-lost.

A Pilates instructor at a strip mall studio in San Marcos had all three ready when I pulled up. She had a break between classes and texted me the VIN before I left my last job. Her Altima needed a spare and with the VIN, I already knew her Smart Key, FCC ID KR5TXN4, and the exact 5-button configuration before I arrived. I had the blank prepped in the van on the drive over.

I used my VVDI2 to clone the transponder from her working key onto the new blank. Because she had the VIN ready and a working key present, I skipped the lock decode entirely and went straight to cutting and programming. Total time from parking my van to handing her a tested spare was 17 minutes.

That's the fastest version of this job at around $254 total. Dealer charges $436 for the same key without the speed.

Nissan Altima Mobile Service FAQ

Real costs, no dealer surprises

How long does a 2019 Nissan Altima key replacement take?
Most Nissan key replacements take 15 to 45 minutes once we are at your vehicle. A straightforward add-a-key on an Altima or Frontier can program in about 10 to 15 minutes. A Rogue or Pathfinder Intelligent Key with NATS server-based security may take closer to 30 minutes. Either way, you are looking at well under an hour from the time we arrive to the time you have a working, tested key in your hand. Compare that to Nissan owners who report dealers booking them for one to two hour appointment windows for the same 15 minutes of actual work.
