Unlocking a car with a key can sometimes trigger the alarm to go off. To avoid this, try locking and unlocking the driver’s side door using the key, as it can reset the alarm system and stop the alarm from sounding.
If the driver’s side door doesn’t work, try the passenger door. Additionally, turning the vehicle on can also help deactivate the alarm.
Reasons Why Car Alarm Goes Off When Unlocking With Key
There are several reasons why a car alarm may go off when unlocking with a key. One possible cause is a faulty key fob. When the key fob is not in proper working order, it may be unable to send the signal to the receiver unit inside the vehicle, causing the car alarm to go off unexpectedly. Another potential reason is a dead battery in the key fob. When the battery in the key fob is low or completely dead, it may cause issues with the signal transmission and lead to the car alarm being triggered. Additionally, corroded battery terminals can also be a culprit. Corrosion on the battery terminals can interfere with the electrical connection and cause the car alarm to activate when unlocking with a key. It is important to address these issues to avoid any unnecessary alarm activations.
