Common Questions
Will this work if my original key looks the same but has a different FCC ID?
No. Even if the shell is identical, if your original key uses FBA or FBC, this remote will not program. It is strictly for HYQ14FBF systems. Always match the FCC ID before ordering.
Can I program this key myself?
No. Modern Lexus smart proximity remote systems require specialized diagnostic equipment. A professional automotive locksmith is needed to sync the new push-to-start key to your vehicle safely.
What arrives in the box?
You'll get the replacement key with a fresh CR2032 battery already inside, plus the uncut LXP90 emergency blade. You just need to take it to a locksmith to have it laser-cut and programmed.
