Someone else's remote opening my 2003 4Runner's rear window

I reside in one of the most densely populated counties in the USA so this is more likely to occur here. I live in Brooklyn, NY . I'm a tradesman and I use a 2003 4Runner to go from job to job...I came out 4 weeks ago on a Monday morning (after not using the 4Runner for 48 hours). The rear window was open and $1000 worth of tools were gone (I think it was a crime of opportunity upon a lowlife finding that rear window open. I always check the rear window when walking away and it was closed). I replaced all my tools and have been trying to park it within visibility from my home windows. I looked at the 4Runner about 1am last night, it was fine and I went to sleep. I awoke about 7 am and looked out the window THE REAR WINDOW WAS OPEN....I ran out of the house panic stricken...everything I replaced was MIRACULOUSLY still there... I think someone else's transmitter is unintentionally opening my rear window.... Any easy way to change the frequency that opens that rear window? Any suggestions would be appreciated...Thanks in advance...

 

can you pull the fuse that contrils the rear window?

 

I'll try that...Thanks...
