Key Replacement - Save vs Dealer in San Diego

2012 Land Rover LR2 Smart Key Replacement - Fast, Affordable & Professional

I got a call from a guy parked near the Nestor side of Otay Mesa. He had his 2012 LR2 and a fob that had stopped talking to the car. Not dead, just unresponsive. The doors would not unlock from the handle, the dash was sitting there with a key-not-detected warning, and he was standing outside in the heat running through every button like one of them was going to change its mind.

He told me he had already swapped the battery twice. Bought two batteries from different stores. Still nothing.

When I got there, I pulled the fob apart on the hood. The CR2032 was fine. What I found was a hairline crack in the circuit board trace near one of the button contacts. Not visible until you look close under decent light. That kind of damage usually comes from dropping the fob on a hard surface. He remembered dropping it in a parking garage a few weeks back and figured it was fine because it kept working for a while after. These things can limp along after an impact and then quit when the trace finally gives out completely.

A fresh fob, programmed on site through the OBD port, synced to his existing key memory. Tested every button, walked the door handles, confirmed the dash warning cleared. He was back in the car in under forty minutes.

He had already called the dealer before he called me. They told him to tow it in and expect to wait on a parts order. No timeline, no estimate, just tow it in and wait. He saved a good chunk going this route and did not lose his car for a week.
