Key Replacement - Save vs Dealer in San Diego

2011 Lincoln MKX Smart Key Replacement - Fast, Affordable & Professional

Out near the Spring Valley border in Lemon Grove, a restaurant owner called me about his 2011 Lincoln MKX. He'd bought it used a couple of years back with one fob, kept meaning to get a spare cut, and never got around to it.

Then the fob hit concrete in his driveway. The shell split clean, the emergency blade popped loose, and the circuit board was sitting exposed in two pieces of cracked plastic. He had zero working keys and a lunch service starting in a few hours.

When I got there, first thing I did was look at the board. No visible damage. The contacts were clean, the chip was seated, and nothing had bent on impact. That mattered a lot because a good board means I'm doing a shell swap, not a full all-keys-lost reset with timed security cycles.

I moved his original board into a new shell, reseated the CR2032, and cut a fresh emergency blade by decoding the door lock. Then I walked every function: door handles, the start button, the lock and unlock, making sure the existing registration was still solid and the car was reading the fob at normal range. Everything worked. Start to finish, about 40 minutes.

He asked about the dealer on his way back inside. I told him they'd quoted him the full replacement price regardless of whether the board was good, because they don't do shell swaps. He saved a good chunk. The board being intact was the real win -- and the only reason that was possible was because he called before he threw the cracked pieces away.
