2023 Nissan Maxima Smart Key Replacement - Fast, Affordable & Professional
Worst case on a 2023 Nissan Maxima is when a previous tech attempted all-keys-lost, the car battery died during programming, and the immobilizer threw errors. Power interruption mid-security-handshake can lock the module into a fault state that makes some locksmiths pack up and leave.
A customer at a smog check station in San Ysidro had exactly this. Another locksmith attempted a key replacement on his Maxima, the car battery sagged during programming, and the immobilizer went into lockout. The other tech left. The smog shop called me.
I brought my ACDP as backup in case I needed to read the ECU directly. In this case, I recovered through OBD by stabilizing the battery with my jump pack first, then clearing the fault codes with my IM608 before starting a clean programming sequence. His Intelligent Key, FCC ID KR5TXN7, was a 5-button proximity fob. The fault cleared once the module reset, and the new fob learned on the first attempt. I showed the smog shop what had gone wrong so they'd know the signs.
Total job time was about an hour and a half, which is longer than normal. His bill was $241. The alternative was a flatbed to the dealer and $418 or more. I carry backup tools and backup power for when the first approach hits a wall.

“I got locked out of my vehicle and also lost my key. Marco came out, made a new key for my Toyota, and got me back on the road. He was professional, friendly, and clearly knows what he is doing.”
“My ignition would not turn in La Jolla and I thought I needed a tow. EZ Car Keyz repaired the ignition on the spot and also made a spare key for safety. The technician worked carefully and confidently.”
“Niv showed up, did his thing, and just like that I had two new keys for a fraction of what the dealership quoted. I have zero reservations recommending him to anyone who needs car keys replaced.”
