Buying Guide
What to consider before buying
- Vehicle compatibility: Ensure the device supports your make, model, year, and key type (blade vs. fob, transponder chip, etc.). Some models (e.g., certain Audi, BMW, VW, Volvo) are explicitly excluded by several devices.
- One-vehicle vs. multi-owner use: Many kits restrict use to a single vehicle for security. Check the allowed VIN or vehicle count.
- Need for blade cutting: If your original key has a blade, you may need to purchase and cut a blade separately.
- App availability and setup: Most kits require downloading a companion app from the App Store or Google Play. Ensure you can access and operate the app and QR code setup.
- Safety and reliability: Look for devices that emphasize secure programming and avoid potential harm to the vehicle’s immobilizer system.
