Essential Lexus LS400 Keys

iKeyless – Lexus Transponder Key (Part No.LEXKEY300)

Lexus Transponder Key

from

$30.49
Needing a new key? We’ve got you covered! This key contains an embedded micro-chip called a transponder. Each transponder has its own unique code–it’s the key’s ‘fingerprint’. When the key is inserted into the ignition and turned, the transponder is energized and broadcasts its unique code to the car’s receiver in the dashboard. If the car’s receiver recognizes the code, it will allow the car to start. This specific key holds a Texas 4C transponder chip. This key also has a high security blade, a preventive measure against ignition picking and key duplication. Cutting and origination services for this key will need to be performed with a special laser cutting machine.

Product Features:
  • Replacement Key with Texas 4C Transponder Chip
  • Contains a transponder chip for enhanced security
  • Key blade ready for cutting and pairing
