Frequently Asked Questions
1. How do I verify I have a "Board E" remote?
Lexus utilized multiple boards (E, G, etc.) for the same FCC ID. You MUST open your original remote and look for the letter "E" stamped on the circuit board. If your board has a "G", this remote will not work.
2. Can I program this key myself?
No. This proximity key requires specialized diagnostic equipment to synchronize with the immobilizer system. You must contact a professional automotive locksmith or a Lexus dealer for programming.
3. Does it include the emergency key blade?
Yes. Each fob comes with a fresh CR1632 battery and an uncut LXP90 emergency blade that must be laser-cut to match your vehicle's door locks.
⚠️ Critical Verification Notice
Lexus proximity systems are board-specific. This remote will ONLY work if your original circuit board is stamped with an "E". Please verify before purchase. Professional programming is mandatory.
