Car beeping on startup as if the keys are outside of the car

I think I accidentally pressed a button combo yesterday that is causing this. Basically when I push the start button the car will honk 2 times, just as it does when you start the car and exit the vehicle with the keys. How can I fix this? Keys are in my pocket on startup just as they've always been.

I still need help with this. It actually happens as soon as I close the door and the car is off. I can't find anything about it

maybe weak battery in remote?

Should get a message on the dash if the FOB battery is getting low.

both trunk and hood are fully closed?

Yeah, I reclosed everything. It hasn't happened in a day, hoping its gone

Mine does it every once in a while. Hasn't happened enough to detect any kind of pattern, though.

I posted this in another thread about the same thing. If you keep your keys in your right pocket when you get into the car, watch and see if the key fob hits the steering wheel when you get in. I noticed I was doing this and it was hitting the lock or unlock button while my door was open, and when I closed the door it double honked.

If it is only doing it when you actually hit the Start button and not when the door closes then it's probably something different and I have no idea haha
