Common Questions
Will this work if my original key looks the same but has a different FCC ID?
No. Even if the shell looks identical, the internal board and the FLC system are different. This remote will only program to vehicles that use FCC ID: HYQ14FLC. It is not interchangeable with older FBA, FBB, or FLB models.
Can I program this key myself?
No. This proximity key requires specialized diagnostic tools that connect to the car's OBD2 port. A professional automotive locksmith is needed to sync the new push-to-start key to your vehicle.
Is the emergency blade ready to use?
The remote includes a new LXP90 emergency blade, but it is uncut. You will need to have it laser-cut by a locksmith to match your vehicle's door locks.
⚠️ Check Your Original Remote
Lexus systems are very specific. This smart proximity remote is only for vehicles requiring FCC ID: HYQ14FLC. Please verify your original remote's info before ordering to ensure it can be programmed to your car.
