How to turn off warning alarm??

Hey guys!! I'm wondering if anyone knows how to turn off the warning noise in a 2015 Toyota Tacoma. When the truck is locked and someone tries to open the door it'll make a loud beeping noise (which is the warning noise I'm attempting to explain) which is cool BUT every night at around 3-4AM the truck makes that noise and wakes me up. I'm almost positive it's my neighbors cat probably jumping in the bed of the truck but it is driving me insane. Does anyone know how to turn that signal off? Thanks in advance!

 

That’s a aftermarket alarm system. The stock trucks don’t do that.

 

Do you have a KARR sticker on the driver door window lower right? Is there a lil blue flashing light and button on the dash where your shins are under the steering wheel?

 

Try holding the lock and unlock buttons at the same time

 

I dont have the KARR sticker but yes I have the little blue light by my shins lol

 

Sounds like you likely have a KARR system then. You can turn down the sensitivity of the glass break sensor (a microphone). Take a picture of the lil black box with the blue button / blue light, also follow the wires attached to it and take a picture of the box it connects to.
