new batteries should help........ but others experience that it dont....mine didnt help and its sucks..

 

yup, same here. I need to be at least 5ft away from the car for my key signal to work. Maybe 10ft if I'm lucky. At first I thought maybe it was low battery but I installed a new one and no difference. However my RX300 gets almost 30ft with no problem.

 

Yeah, the waves bounce on your skull or something and amplifies the signal. Not sure about health risks, though LOL

 

I have a mouth full of fillings so I think that helps. LOL!

 

I don't know about health risk the rf that comes out of remote at any giving time is. Way less than a phone call or people that use there fm transmitter(gag!!!!) in there cars to listen to there mp3

 

i reall am not kidding about this, i shot a video of it last night but i didnt DL it to my computer to upload it here...will do so soon. only time it normally doesnt work is if you have broken your jaw cause you loose the natural amperage your body produces

 

Ya the under the chin thingy really works. It increases range considerably.

I think Lexus kept the range short on purpose for security reasons. You don't want to accidentally hit the unlock button when your 100 ft away from your car, or be tempted to hit the unlock button when your 100 ft away from your car to get your groceries in, giving a theft or car jacker time to enter your car before you do.

 

hrmmmm so no real reason this is happening! sux!

 

The reason Lexus did this is to protect the codes that the remote sends out to the receiver unit in the car. There are Hi-tech thieves that have "toys" that will catch these codes when you use your remote.

 

I tried it again tonight after sushi and it was 5 car lengths and it unlocked.. Sorta shocked me to be honest.

 

This is why they have rolling codes. Most modern (post @ 2000) remote keyless systems roll the code every time it is used so that someone with a code grabber cannot get it. Most decent modern garage door openers do this now, too.
