2018 Lexus LS Smart Key Replacement - Fast, Affordable & Professional

She had spent most of the afternoon at a specialist's office in El Cajon with her father, who uses a wheelchair. They were finally done, she had him loaded up alongside the car, and she pressed the start button.

Nothing. She held the fob against the button like she'd seen someone do once. Nothing. It was past six in the evening, the dealership was already closed, and she had an elderly man in a wheelchair on the pavement next to a car that wasn't moving.

She called me.

Fletcher Hills to that part of El Cajon is not a long drive. When I got there, she was calm but quiet in the way people get when they're holding it together for someone else's sake.

I got the door open using the mechanical insert key built into the fob, which is something a lot of LS owners forget is even there. Once I was in and had the diagnostic port connected, the scan told the story: the battery inside the fob had corroded the contact plate. The transponder chip wasn't communicating. The car's security system wasn't rejecting the key, it simply wasn't hearing it.

I replaced the fob, registered it to the vehicle, and walked every function before I called it done. Lock, unlock, the trunk release, the start button from outside the car. Then I started it myself and let it run.

The whole call, from the moment she reached me to the moment the engine was running, was under fifty minutes. She got her father home that evening in his own car, in his own seat. The dealer was a thought she never had to finish.
