Quick Info
Will this work with other FCC IDs?
No. The LS series uses a unique board configuration. Even if the shell looks identical, it will not program if your original key uses FBA or FBC. Match the HYQ14FBF FCC ID before ordering.
Can I program this key myself?
No. This proximity key requires specialized diagnostic equipment. An automotive locksmith must connect to the OBD2 port to sync the new push-to-start key.
What is in the box?
You receive the complete remote, a pre-installed CR2032 battery, and the uncut LXP90 emergency blade. The blade must be laser-cut by a locksmith to match your door lock.
