This instructable will show you how to increase the range on any car key remote.

Step 1: Get Inside It

Lets start by using a small flat screwdriver and pry the key remote open. Then locate the antenna(it looks like a small silver box). Then using sandpaper lightly scrape off some if the silver coating.

Step 2: Adding Some Wire

Now solder a small length of wire to that antenna. Then close it up.

Step 3: Try It Out
