🔧 PRO TIP
Dealer quotes for a Q50 key run around $500 for fob plus programming. Q50 owners online report paying $75 for an OEM fob and $90 for locksmith programming, totaling about $165. That price gap is one of the biggest in the Infiniti lineup.

2019 Infiniti Q50 Smart Key Replacement - Fast, Affordable & Professional

BSIS license LCO#6792 means I passed California's background check, maintain active liability insurance, and operate a registered locksmith company. NASTF certification means I have access to the factory security database that provides key codes and immobilizer data unlicensed operators can't get. Google Guaranteed means Google verified my credentials independently.

A dermatologist at her clinic near Third Ave Village told me she'd verified my credentials before calling. She had a 2019 Infiniti Q50 and needed a spare smart key, but she'd heard about unlicensed operators damaging luxury car electronics. She wanted proof of legitimacy before anyone touched her Infiniti.

I used my Smart Pro to program her replacement fob through OBD. The Smart Pro runs the Infiniti security access sequence and learns new keys using the factory-supported PIN procedure. Her fob, FCC ID KR5S180144014, was a 5-button smart key that I cut, programmed, and tested at the car. NASTF access matters on Infiniti because it provides the factory security codes the programming tools require.

Her spare cost $281. Dealer quoted $528. Real receipt, real license number, real phone number that works next month. You can look up LCO#6792 on the BSIS website right now.

“My car keys were stolen on a cold evening and Nick drove all the way out to Santa Barbara. He got into my car, made a new key, and charged $100 less than another company. Friendly, skilled, trustworthy, and genuinely caring. Nick is a hero.”

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”

Infiniti Q50 Mobile Service FAQ

Real costs, no dealer surprises

Do you use OEM or aftermarket keys on Infiniti vehicles?
We use OEM spec keys that match the factory part number, chip frequency, and blade profile for your specific Infiniti. Professional-grade aftermarket intelligent keys designed for locksmith use work reliably on Infiniti models, but cheap Amazon and eBay clones are a different story. Locksmiths report that ultra-cheap keys for Nissan and Infiniti platforms show up with incomplete electronics and intermittent start issues. We carry keys we have tested and verified on Infiniti vehicles so you get a key that works and lasts.
