2023 Lexus LC Smart Key Replacement - Fast, Affordable & Professional
Patterson Road corridor, right by the Marina West shopping center. The LC500 owner had that look - half annoyed, half impressed by his own bad luck.
"Card key battery low" had been flashing for weeks. He ignored it. Then the fob died completely in the Vons parking lot, engine running, and he couldn't figure out how to turn it off without the smart key working. He actually called the dealer first. They wanted the car flatbedded in.
I showed him the trick: hold the dead fob right against the start button. The backup antenna still reads the NCF29A1M chip even with zero battery. Push to stop. Then we got to the real work.
New CR2032, but these HYQ14FLC fobs have a known issue where the battery clips lose tension. Bent the clips back for solid contact, tested all four buttons plus the trunk release. The "Card key battery low" warning cleared immediately once the ECU saw good voltage again.
The whole thing took maybe fifteen minutes in the parking lot. He mentioned the dealer wanted him to leave it overnight for "diagnostic verification" of the smart key system. For a battery.
Some LC owners carry a spare CR2032 after learning about the weak clip design. Smart move on a car that retails north of a hundred grand.

“I needed a car key replacement in Hillcrest and EZ Car Keyz helped me immediately. The technician programmed a new smart key right next to my car and tested every function before leaving. Fast, friendly, and very professional.”
“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.”
“A+ service at an even better price. Tim was a lifesaver. I lost my original and only key for my Audi and he was willing to come to my location at 8pm the same day. He worked fast, communicated clearly, and made sure everything worked before leaving.”
