🔧 PRO TIP
The 2010 EX35 smart key system is shared across several Infiniti models from this era, so the programming workflow is consistent and well-documented. One thing owners miss: when the fob battery dies completely, the car can log a communication fault in the immobilizer even after you swap in a fresh CR2032. The fob might still respond weakly or not at all until that fault is cleared through the OBD port. So if you hand someone a new battery and the fob still acts up, that's why. The fix isn't the battery again. It's clearing the fault and confirming the fob is still enrolled. Also, the EX35 has an emergency key slot built into the door handle area. Most owners have never used it and don't know it's there until they're standing outside a locked car at night.

2010 Infiniti Ex35 Smart Key Replacement - Fast, Affordable & Professional

He'd been in the air for five hours. Cross-country flight, Tuesday afternoon, landed in San Diego and walked straight to the long-term lot in Bonita where he'd left his 2010 Infiniti EX35 before the trip. He clicked the fob. Nothing. Clicked again. Still nothing. The car just sat there.

He tried holding the fob closer to the door handle, which is what everyone tries. Then he called the Infiniti dealer. First available appointment was Friday. It was Tuesday. He had a territory meeting in three hours and his whole bag was in the trunk.

He found me through a search and asked if I could come to the lot. I was there in under an hour.

The door wasn't a problem once I showed him the emergency key insert built into the handle. He'd owned the car for years and genuinely had no idea it was there. We got in, I connected through the OBD port, and the diagnostic confirmed what I suspected: the fob was still paired and enrolled, but a dead battery had triggered a communication fault in the immobilizer that was blocking the wireless signal from registering properly. Even with a fresh CR2032 seated correctly, the system was still holding that fault.

I cleared it, verified the fob was reading clean, and walked every function: lock, unlock, the trunk release, and the panic button. All working. He was on the road before the hour was up.

The dealer would have had his car sitting on their lot until Friday before anyone even looked at it. He mentioned that on the way out, almost as an aside. He wasn't mad about it. He just seemed relieved someone had actually shown up.

“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.”

Infiniti Ex35 Mobile Service FAQ

Real costs, no dealer surprises

What if I need an Infiniti key after hours or on the weekend?
Call us. Infiniti dealer service departments are closed evenings and most of Sunday, and even Infiniti's roadside assistance program can tow your car to a dealer lot without getting you a programmed key until someone is in the building and available to handle it. That could mean your car sits until Monday morning. We work evenings and weekends in Chula Vista and the Bonita area. For a 2010 EX35, as long as you have at least one working fob, we can be at your location and have a spare added in roughly 30 to 45 minutes. All-keys-lost takes longer because of the security access and enrollment steps, but it's still a single visit and you leave with a working key.
How long does programming actually take once you're at my car?
Can you make a key faster than the dealer?
My fob works sometimes and cuts out other times. Is the key going bad or is this something else?
I bought a replacement fob online. Can I program it myself to my 2010 EX35?
