Here's how I increased the signal from my Keyless entry remote 7x!
I could only lock/unlock my truckicon1.png from ~5 feet. Now I can do it from 35 feet away.

Items needed:
Soldering iron
Solder
~4" wire 

Here's the average distance for the factory remote (in my case). 



The FCC has a maximum signal output that the manufacture must abide buy. 


Process:

Use a flat screwdriver to separate the two halves of the remote


The 2 halves & the buttons were little dirty.... Clean 'em up.

 

Grab your Soldering iron, solder & a short piece of wire.


Solder the wire to the area pictured.


Route the wire like this.


Put the two halves back together and test it out. 

Any questions?
