2003 Infiniti QX4 Transponder Key Replacement - Fast, Affordable & Professional
BSIS license number LCO#6792 is publicly searchable on the California Bureau of Security and Investigative Services website. You can verify it right now. That license means I passed DOJ and FBI background checks, maintain active liability insurance, and operate a registered locksmith business.
An oral surgeon at his office near Beyer Blvd told me he verifies every service provider. He had a 2003 Infiniti QX4 and needed a spare smart key. He'd already checked my BSIS number, read my Google reviews, and watched two YouTube videos before picking up the phone.
I used my ACDP to pull his IMMO module data as a safety backup before programming. NASTF certification gives me authorized access to factory key data for Nissan and Infiniti platforms, which means correct PIN codes and factory procedures, not workaround methods. His fob, FCC ID , was a 3-button smart key programmed through the correct data path.
His spare cost $138. Dealer quoted $316. He said he appreciated the transparency. Look up LCO#6792. Read the reviews. Watch the videos.

What certified service looks like in reviews
“I needed a car key replacement in Hillcrest and EZ Car Keyz helped me immediately. The technician programmed a new smart key right next to my car and tested every function before leaving. Fast, friendly, and very professional.”
“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”
“A+ service at an even better price. Tim was a lifesaver. I lost my original and only key for my Audi and he was willing to come to my location at 8pm the same day. He worked fast, communicated clearly, and made sure everything worked before leaving.”
