🔧 PRO TIP
The 2008 Infiniti M45 runs a Smart Key system, which means the fob does more than lock and unlock. It also communicates with the immobilizer at startup. When owners say "the car won't start," the problem is often the fob, not the engine. The fob takes a CR2032, and a low one will cause intermittent no-start before it fully dies. Before assuming the worst, swap the battery and check that the contacts inside the fob housing are clean and making solid contact. Also worth knowing: if the smart key fob is completely dead, there is a physical backup key blade folded inside the fob body. That blade opens the door manually. Getting in is step one. Starting the car with a dead fob is a different procedure and needs the right tools on site.

2008 Infiniti M45 Smart Key Replacement - Fast, Affordable & Professional

There is a restaurant near Winter Gardens, the kind of place with valet parking out front. The owner drove a 2008 Infiniti M45 and had been dealing with a frustrating problem for a few weeks. The car would occasionally show a key-not-detected warning on the dash even though the fob was sitting right in his hand. Sometimes it started fine. Sometimes it made him stand there a second time before it would cooperate. He figured the fob was dying.

He mentioned it to the valet, who passed my number along.

When I got there, the CR2032 inside his fob was reading low. Not dead, but not healthy either. The contacts had a slight film on them, probably from sitting in a pocket with loose change. I opened the fob on the hood of the car where he could watch, cleaned the contacts, seated a fresh CR2032, and closed it back up.

Then I did what I always do before I pack up: walked every function. Lock, unlock, each button on the four-button fob, and a clean start cycle. No more warning on the dash. No hesitation.

He had already been quoted a full smart key replacement at the dealer. That quote was going to cost him real money and at least a few days without his car. What he actually needed was a battery and ten minutes.

I left him with a working fob and the backup blade method explained, just in case. He saved a significant chunk compared to the dealer path, and he didn't replace anything that was still doing its job.

“Tim was GREAT. I honestly swear he must have had my keys made before he even showed up. The entire process was insanely fast, from the initial phone call to having the keys in my hand. No one will beat the pricing, efficiency, or outstanding service.”

“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”

Infiniti M45 Mobile Service FAQ

Real costs, no dealer surprises

I am locked out of my 2008 Infiniti M45 with no spare. Can you come to me in Lakeside?
Yes, that is exactly what we do. Call us and we come to wherever the car is sitting in Lakeside or the Winter Gardens area. We carry the tools and blanks for this vehicle, so there is no tow truck involved and no waiting at a dealership service counter. One thing worth knowing about the M45: the fob has a physical backup blade folded inside the housing. If the fob is dead or you have no fob at all, that blade is how you get the door open manually. From there, getting the car to start is a separate step that requires the right diagnostic equipment. We handle both on site.
Does Infiniti really require me to tow the car to the dealer for a replacement smart key?
What do I need to show before you can cut or program a key for my M45?
I bought a replacement fob online for my 2008 M45. Can I program it myself?
My 2008 M45 starts fine but the fob buttons stopped working at range. What is going on?
