How to Get a Replacement Lexus Key

Lexus key replacement can be obtained at the dealership or with the assistant of local locksmith in your area.

The main difference between the two is that a car locksmith will travel to your location, while getting a key made at the dealer requires you to tow your vehicle there.

Program a Lexus Key

Lexus car keys & Fobs can be purchased from a locksmith, online or by visiting parts department at a local Lexus dealer.

After buying a replacement key or Lexus fob, you still need to cut the blade and program the transponder chip and the remote/ keyless features.

Programming a Lexus smart key requires diagnostic tools. Customers with only one key who chose to get a spare key online may need to contact a nearby automotive locksmith to cut & program the key.
