Hi, new here so be nice please! I have a 2019 XV - only done 20k. Key fob battery lasted for the first 3 possibly 4 years, but now i'm having to change it every 6 - 8 months as it keeps telling me it isn't detected or I stand there like a lemon shaking my key before it lets me in. There must be such a thing as a receptor within the car - is it possible that's the problem? Can it just be cleaned, if so where is it? Thanks

Don't think they have a seperate battery for the locks so if it starts theres plenty of power.

If the battery died did it leak or corrode the contacts? Did you replace it with a rechargeable one? iirc they get charged while in the ignition

How long they last will also depend on how much you use it of course.

Hello Shirley, I had the same issue with my Impreza ( XV is basically an Impreza with more ground clearance ). Key fob battery replacement every few months. What you need to do is put your fob into sleep mode when you lock the car. That way the car and fob will not be constantly communicating using up both the fob and main car battery.

If when you lock your car you hold the lock button down and while keeping it down also press the unlock button twice - two flashes from the key fob red light will confirm the fob is now in sleep mode. To unlock do as usual. Press unlock once for the driver's door or twice for all doors.

I hope this helps 🙂
