What could be causing my Subaru remote start to not work?
There are several reasons why your Subaru remote start may not be functioning properly. One common cause is a drained or weak battery in the key fob. If the battery power is low, the signals sent to the vehicle may not be strong enough to initiate the remote start. Additionally, check if the key fob is damaged or if the buttons are stuck, as physical damage can impede functionality.
Another factor could be an issue with the vehicle’s security system or a blown fuse. If your Subaru’s anti-theft system is triggered or malfunctioning, it may prevent the remote start feature from engaging. Furthermore, ensure you are within the appropriate range of your vehicle, as being too far away can hinder the remote start activation process.
How can I check if the key fob battery needs to be replaced?
To check if your key fob battery needs replacement, try using the remote start functionality from a closer range to see if it works. If the remote start activates when you’re very close to the vehicle but not when you’re farther away, it’s likely the battery is low. You can also perform other functions with the key fob, like unlocking or locking the doors, to see if those are sluggish or unresponsive.
If you suspect the battery is low, it’s relatively easy to replace. Most Subaru key fobs have a small cover or a slot that can be opened with a coin. Once you access the battery compartment, take note of the battery type to ensure you purchase the correct replacement.
