What to Do When the Alarm Sounds When Using the Spare Key to Open the Car Door?
1 Answers
Insert the key quickly and power on the car after opening the door to stop the alarm. Related details are as follows: 1. For a car locked with a remote, when using a mechanical key (whether the main key or the spare key) to open the door, the car's computer will interpret it as an intrusion because the car was locked via remote but opened mechanically, which it defaults to as a forced entry, triggering the alarm. 2. If the car is locked and opened with a mechanical key, the alarm won't sound. This is a safety feature, and the alarm will cancel once the engine is started. 3. The remote key locks the car and activates the alarm simultaneously, so using the spare key to open the door will trigger the alarm. Quickly inserting the key and powering on the car after opening the door will stop the alarm. Since the spare key contains the engine decoding chip, the car can be started and driven away. Additional notes on car spare keys: 1. The spare key is for emergency use and should generally not be left inside the car. Otherwise, it may attract thieves, causing significant damage to your vehicle. 2. Don’t carry the spare key with you out of fear of locking yourself out. If you accidentally lose it and someone finds it, they might locate and steal your car, resulting in a substantial loss. 3. It’s best to keep the spare key at home. If you accidentally lock your keys inside the car, stay by your vehicle and have a family member bring the spare key to avoid theft and significant loss. However, when traveling long distances, carrying the spare key is advisable, preferably on your person. Otherwise, if the primary key is lost or unusable, you might have to break a window to retrieve the spare key, leading to considerable damage.
