Quick Info
How do I verify my Board ID?
You must open your original remote case to find the 4-digit Board ID (0440) printed on the circuit board. This remote will not program if your current board uses a different number, such as 0410 or 2110.
Can I program this key myself?
No. This proximity key requires specialized diagnostic tools. An automotive locksmith must connect to the car's OBD2 port to sync the new push-to-start key to the immobilizer.
What is in the box?
The package includes the complete remote, a fresh CR2032 battery already installed, and an uncut LXP90 emergency blade. The blade will need to be laser-cut by a locksmith.
⚠️ Technical Fitment Note
This remote is specifically for 314 MHz systems. It is not interchangeable with 315 MHz versions. Always verify both the FCC ID and Board ID before ordering to ensure a successful programming setup.
