Horn makes a short peep when unlocking sometimes

[Hoseman50]

Evening everyone.
I’ve noticed this has been happening more frequently lately.
Sometimes when you go to open the car just as it unlocks the horn sounds a short peep.
Also, sometimes on approach it doesn’t unlock and you have to press the unlock on the remote.
Could this be related?
I’m wondering if it could be a signal that the remote battery is getting low.
Any thoughts would be greatly appreciated.

I've noticed that recently but it didn't happen when the car was newer. Maybe try the other key for a bit of it has been used less?

I’m going to try the other key for a few days to see if it makes a difference
