Important Note
Some vehicles with IMMO or PATS may require key programming after installation. This is normal.

If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

Installation was straightforward, and I had the engine running smoothly again in no time. The quality feels top-notch, just like the original part, and I appreciate that I didn’t have to mess around with complicated programming or extra software.
