Key Replacement - Save vs Dealer in San Diego

2014 Nissan Cube Smart Key Replacement - Fast, Affordable & Professional

I got a call from someone parked at a spot near Cardiff-by-the-Sea, one of those side streets just off the main drag in Encinitas. His 2014 Cube had been sitting there while he grabbed food.

When he came back out, the fob wouldn't unlock the doors. He got in with the mechanical key tucked inside the fob, tried the start button, and the dash lit up with a key-not-detected warning. Engine went nowhere.

He told me he'd already swapped the battery twice in the past month. That detail matters. When someone keeps swapping batteries it usually means the contacts inside the fob are not making clean contact, or something deeper is going on with the registration between the fob and the immobilizer.

I pulled up to him maybe twenty minutes after he called. The fob internals looked fine once I opened it up, contacts were solid, battery was seated right. So I moved to the diagnostic port. Ran a read on the immobilizer and found the registered key count looked off, which pointed to a registration issue rather than a hardware failure on the fob itself.

Reprogrammed the fob on site. Start button worked, doors worked, everything came back. He asked if the dealer would have figured that out. I told him probably, eventually, but they'd have billed him for the diagnostic time, the programming, and whatever else landed on the ticket while the car sat in their lot. He said he'd gotten a quote from them a few weeks earlier for a spare key that was way more than what I charged him. He hadn't bothered because of the price. I told him having a spare on a single-key vehicle like this is worth doing while I'm already there.

He let me make the spare on the spot.
