How to Use the Spare Key to Open the Car Door Without Triggering the Alarm?

[CameronLynn]

Methods to use the spare key to open the car door without triggering the alarm: 1. Mechanical Key Unlock: Whether it's the primary key or the spare key, unlocking with a mechanical key will be recognized by the car's computer as an intrusion because locking was done via remote while unlocking is mechanical, which defaults to a forced entry and triggers the alarm. However, if you lock and unlock the car using the mechanical key, the alarm won't sound—this is a safety feature. The alarm will cancel once the engine is started. Since remote key locking activates the alarm, using the spare key to open the door will trigger the alarm. Quickly inserting the key and turning on the ignition will stop the alarm. The spare key contains an engine decoding chip, allowing you to start and drive the car. 2. Precautions: The spare key is for emergency use and should not be kept inside the car under normal circumstances. However, if you're going on a long trip, carrying the spare key with you is advisable. Keep it on your person, as losing or being unable to use the primary key may require breaking a window to retrieve the spare key, leading to significant losses.
