trick with remote unlock
idk if it works, but im gonna try it....
Cool Discovery
This only applies to cars that can be unlocked by remote button. Should you lock your keys in the car and the spare keys are home.
If some one has access to the spare remote have them telephone you on your cell phone.
Hold your (or anyone's) cell phone about a foot from your car door and have the other person press the unlock button, hold it near the phone.
Your car will unlock. I tried it and it works. Saves someone from having to drive your keys to you. Distance is no object.

Locked my keys in the car 30 miles away from home earlier this summer. Gave this a shot and it didn't work. Tried holding the phone any distance from 1 inch to several feet and no luck. Tried holding it on an angle, and even by the trunk. Still no luck. Even had my daughter hang up the home phone (land line) and call back on her cell -- still nothing. Got a ride home, grabbed the keys my daughter was using over the phone, pulled in next to my car and the first click opened the door - so I know the sending unit worked fine.
I'm inclined to say its a myth......

Change your remote batterys imo
If you put the flat part of the clicker against your chin it will reach out farther.
Walk away from your truck and get to where it won't work anymore and then try it and I bet it will reach.

That is also total BS. That isn't how radio transmitters work. The ONLY reason it might work better against your chin is because it is up higher and out in front of your body. There is nothing in your body that will help amplify, reflect, refract, or improve your keyfob.

Your son's car remote control has a miniature radio transmitter that is built into the key ring and which sends a coded message to a receiver in the car. You don't have to point the device directly at the receiver in the car, but it will help to increase the range if you press the remote control against your body. In fact, any part of the body will do, not just your chin. Arms and legs work too. And you can have endless fun pointing your bum at your car while pressing the key ring against your buttocks.
The range over which the remote control operates nearly doubles when you involve your body because your body picks up the radio signal and acts like a large aerial, transmitting it more effectively to the car.
The key and the body act like the two plates of a capacitor separated by an electrical insulator. When an electric charge flows into or out of one of the plates, the electrostatic effect drives a similar charge into or out of the other. Although no charge actually crosses the insulator, a current appears to flow for a while until the capacitor is fully charged. Applying a varying current to one plate means that the capacitor never gets fully charged and a current appears to flow indefinitely through the second plate.
This phenomenon, which is called capacitive coupling, works best with rapidly varying currents, which is exactly what the radio transmitter in the key ring produces.
Because it operates at a frequency of 433 megahertz, the current from the key can cross the insulating barriers of your clothing and skin to reach the conducting interior of your body. Your body then acts as a giant aerial when you press your remote control against it

Aaron, that is about as much fact as holding it up to a cell phone 100 miles away. You found what amounts to a well written pile of bull. Your body does not radiate RF and if you knew squat about antennas, you'd know that even if your body could radiate RF, it still wouldn't do you any good in this scenario. Its a lie.
BTW, do you maintain a fleet of 200 portable and mobile radios plus infrastructure where some components cost more than a Ford Ranger to begin with? No, I don't think so. Trust me, that thing you found is BS.
Oh snap. Go back to your igloo.

I'm the last person on the face of the earth to give electrical advise. However I did try the chin thing.
On my 06 FX I can walk away from the truck until it does'nt work anymore. Then walk an additional 25-30ft away. Hold the transmitter up against the bottom side of my chin / throat. Open mouth and push lock or unlock.
It works every time.

A) Your job sounds like you *maintain*. Awesome dude, a janitor *maintains* a public bathroom.
