2004 Infiniti M45 MECHANICAL-KEY Replacement - Fast, Affordable & Professional
I guarantee my work. If the key I program to your 2004 Infiniti M45 fails within my warranty period, I come back and fix it at no charge. Not dealer warranty with fine print. Me driving to wherever you are and making it right.
A tennis pro at the country club near Brown Field had a fair question before I started. What happens if it stops working in a month? His M45 was his daily driver and he couldn't afford to be stranded between lessons.
I told him what I tell everyone. I stand behind every key. Chip warrantied. Programming warrantied. Blade cut warrantied. If something fails on my end, I come back. I decoded his lock with my NI04 Lishi, cut a fresh emergency blade, and programmed the fob through OBD. His remote, FCC ID , was a 3-button unit. I tested start, lock, unlock, trunk, and range. Then I tested again five minutes later because intermittent issues sometimes only surface after the key sits.
Total was $95. Dealer charges $200. My warranty is simple because the process is simple. Program it right the first time using quality fobs and the factory-supported PIN procedure.

What certified service looks like in reviews
“Tim went above and beyond. I struggled all day trying to program a new FOB and nothing worked. Tim helped me patiently, even recommending cheaper options since I was on a tight budget. He eventually came all the way to Ojai late at night and fixed everything.”
“My key fob stopped working while I was at Oxnard Harbor and I thought I was going to need a tow. EZ Car Keyz showed up fast, programmed a new fob, checked everything carefully, and made sure the car was fully functional before leaving.”
“Needed a spare car key made and chose EZ Car Keyz based on their reviews. The reviews were right. They gave me the best price, responded quickly to all my questions, came to my workplace, cut the keys on site, and finished fast.”
