question for extending keyless entry range

Does anyone know how or have any recommendations to increase the range of a standard 1st gen keyless entry, or any sort of product? I do know about holding it to your jaw and opening your mouth but I look crazy doing it in a parking lot.

 

I too have wondered this and only ever thought about the key fob side. The receiver side has much more potential due to its size but I've never looked inside

 

No need to open your mouth!

Just hold the fob to your chin. It's too good not to.

But about this twitch I've recently developed, and this lisp I never had//////

 

Take the can off in pic 3 to expose the circuity. I gained about 1/3 range just now, not joking

 

Y'all got keyless entry? Fancy asses...

 

You got “keyless” too, right? Like, your key broke off in the door and now it’s just...less.
