Common Questions
Is this the correct replacement OEM refurbished smart key for my car?
Yes, if your factory remote uses FCC ID M3N-40821302 and part number 68066350AD, this key fob will pair perfectly. Selecting an OEM refurbished proximity remote ensures you receive an authentic, high-end original internal circuit board for reliable Keyless Go communication, protected by a brand-new outer shell.
What equipment and technical steps are required to program this smart key?
To configure this proximity control, an automotive locksmith or dealer must connect a specialized programming scanner (such as **Autel MaxiIM IM608**, **Advanced Diagnostics Smart Pro**, or **Obdstar**) to the car's OBD2 interface. The technical process requires **reading the vehicle's specific PIN code** from the RFHub/Immobilizer module to bypass factory security, allowing the programming tool to pair the unlocked PCF7953 transponder chip to the ECU.
What exactly is included with this original refurbished keyless remote?
Your order includes a complete, fully tested device ready for setup: the original factory internal circuit board with its integrated ID46 chip (professionally cleared and unlocked for a new pairing), a new 4-button shell casing, a fresh CR2032 battery, and an uncut Y172 emergency insert key blade.
