🔧 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.

2020 Nissan Altima Smart Key Replacement - Fast, Affordable & Professional

People lose all their Nissan keys more often than you'd think. The most common story isn't dramatic. They just never got a second key. They bought the car used with one, always meant to get a spare, and a few years later that one key finally gives out.

A pharmacy tech at a carport in Poway had exactly that story. Her only key to her 2020 Nissan Altima cracked at the housing seam and the blade snapped when she pulled it from her pocket. The fob was in two pieces and the car wouldn't detect it.

I used my VVDI2 to read the transponder data from the cracked fob since the chip was still intact inside the broken housing. That saved time because I didn't need a full all-keys-lost procedure. I decoded her door lock, cut two fresh blades, and built two new fobs. Her key uses FCC ID KR5TXN4, a 5-button Intelligent Key that I rebuilt into new shells with the cloned chip data. I showed her the chip from the cracked fob so she could see it was still good.

She went from zero working keys to two in about 40 minutes. Total was around $241. A full AKL without the broken pieces would have cost more, and the dealer wanted $418 either way. If you still have the broken pieces, bring them.

“Super fast service. About 20 minutes from the call he was already there. He had an authentic replacement on hand and made a spare key for my 2017 Nissan Rogue in about 15 minutes. Great prices, friendly, and very professional.”

Nissan Altima Mobile Service FAQ

Real costs, no dealer surprises

My key broke in the ignition. Can you get it out?
Yes. Broken key extraction is a standard job for a mobile automotive locksmith. We use specialized tools to remove the broken piece without damaging your Nissan's ignition cylinder. One locksmith familiar with Nissans warns that once a key breaks off inside, the wafers and channel inside the ignition can get damaged, and even if the broken piece comes out, the cylinder may need replacement soon. Once the piece is out, we can cut a new key from the extracted fragment or from your vehicle's lock data and program it on the spot. Nissan models that still use a physical ignition key are most likely to run into this.
