❓ Frequently Asked Questions (FAQ)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Q1: What does PEPS mean?
A: PEPS stands for Passive Entry & Push Start. With Passive Entry, your vehicle automatically detects the key when you approach the door — no need to press any buttons to lock or unlock. With Push Start, you can start the engine simply by having the key inside the vehicle and pressing the brake pedal + start button.
Q2: What is the difference between this PEPS key and product 642 (non-PEPS)?
A: Both share the same FCC ID (M3N5WY8609) and Part Number (164-R8091), but this product (641) has full PEPS functionality with Passive Entry and Push Start. Product 642 is a standard smart key without PEPS features. The PEPS version is used in higher trim levels. Verify which your vehicle requires.
