Important Safety Information
- Professional Installation Required: This system is complex and requires installation by a qualified car alarm installer. Incorrect installation can lead to vehicle damage or malfunction.
- Compatibility: This system is not compatible with vehicles that have double pulse signals for lock/unlock, pneumatic or vacuum locking systems, factory OEM push start buttons, diesel engines, or certain luxury car models (e.g., BMW, Benz).
- Immobilizer Bypass: If your vehicle has a chip immobilizer in its factory OEM key fob, an extra bypass module (e.g., ASIN: B07NSLPBG7 or B00MEHBVIC) is required for remote start functionality.

- Carefully pry open the key fob shell using a small flat-head screwdriver. Handle with care to avoid breaking the shell.
- Remove the old CR2032 battery from the PCB (Printed Circuit Board). No unscrewing is typically required.
- Insert a new CR2032 battery, ensuring correct polarity.
