[]they use garage door openers which aren't being tracked, or keyless entry transmitters?[]
cuz you look kinda stupid on airplane with a garage door opener & keyless entry transmitter. its too obvious
or maybe TSA wouldnt blink. thank you for flying______airlines. BOOM.
All you need is the outer shell of any cell phone, and just replace the inside with other electronics, and TSA wouldn't notice.
Methinks it's gonna go toward the "Only Speedos Allowed Onboard" rules.
